BY "CONVEYORS"
we mean people who are involved in some way with moving
lamps and lighting devices into society. We posed a series of fourteen questions
specifically for conveyors in addition to six
general questions. We also provided a "History to Go" section for those
who wished to submit general comments.
Selected responses to our questions are posted below. As noted in our privacy
statement, these responses have been edited for spelling and clarity.
There are two other Collecting History pages on this siteConsumers and
Producers. Comparing the responses of all three groups should show how each group's
perspectives on and interactions with lighting technology differ.
Our project is on-going, so remember to add your perspective by submitting one (or
more) of the Collecting History forms.
We have received the following comments
about conveying energy-efficient lighting equipment to society:
"Dimmability, initial cost, and light quality are the three largest real issues I see bothering people. Listing violations that involve substituting compact fluorescents for incandescents, and safety questions associated with those violations are a seldom-considered problem, but non-trivial." "As a lighting designer, I have seen the industry go from using general source ambient lighting (employing lamp sources that waste illumination in the ambient environment) to task-oriented illumination. Task illumination requires specific knowledge of lamp characteristics and beam patterns. Proper use of this knowledge is still sadly lacking in the general population. Usable lights are those that allow the beam pattern of a lamp to be confined to the task-area based on the ceiling height and spacing criteria of the lamps in that area. The relationship between general and task illumination must also be considered as too often designs are based solely on ceiling aesthetic in the space with no regard for actual requirements. "It took awhile, but nowadays most folks readily admit the tri-phosphor T8 lamps running on electronic ballasts are far and away better lighting than standard cool or warm white T12's running on magnetic ballasts. However I still think that the older deluxe halophosphate lamps have a role to play - especially in residential use. Deluxe Cool White and Daylight, and the 5000K Chroma 50 lamps are cheaper than the 80% tri-phosphors and, while not as bright, they give excellent color rendering. In a residential kitchen color rendering is more important than efficiency. And often the fixture already has a magnetic ballast which, until if fails, the homeowner is not usually willing to replace. If one needs more lumens but still wants excellent color, just install a 4-lamp fixture and use deluxe tri-phosphor lamps." "In the construction industry it seems, as elsewhere, that companies are looking for the right light level (lumens per square foot) for the right price (installation cost and operating cost.) I have seen experimental lighting in parking garages that use solar energy to light them. It seems that application could be used in all types of buildings in some way." "I started in the industry in 1984 and in
the past 15 years have seen the change from incandescent sources to fluorescent and
now the beginning of the emergence of L.E.D. technology applied to [general] lighting.
I have seen the change from inefficient ‘Cool White’ fluorescent lamps to highly
efficient ‘tri-phosphor’ lamps. I believe that this has been the best and most
exciting time to be in the lighting industry.” "The banning of the F40CW bulb has been
the best thing to happen to fluorescent lighting. Replacements and new installations
are now using lamps with higher CRIs (Color Rendition Index), and the F40CWX has
made a comeback. Better color rendition makes products in stores look better hence
more product moves, increasing cash flow in the economy. High CRI lighting in the
work place results in higher moral, fewer sick days, fewer errors on the job-this too
may be playing a part in our improved economy.”
"You are a fool not to read and understand
issues involving home, business, and all other lighting issues! What you don't know,
can drain your pocketbook easily!!!"
“[Energy efficiency] is a real hard
concept to sell here in south central Pennsylvania. Energy costs are so low, and the
people so tight-walleted, that even paybacks of under 2 years take forever to get
approved."
"The design community and especially the
energy-legislative community has become so enamored of the concept of energy efficiency
that they have lost touch with some basics of light, physics and quality of
environment. A 20 watt low voltage lamp can be used to create similar light levels
as some compact fluorescents while offering greater control and quality. However the
reaction becomes one of believing that only the use of fluorescent is energy
efficient and environmentally correct. Is a watt not a watt?"
"There is a great need for education
related to this issue since the use of efficient luminaires does not insure that the
best results are obtained. Is daylight considered? Is the whole area illuminated when
only a small space is in use? Has task and ambient lighting been considered? The
issues are endless."
"Most of the designs I have seen recently
that are popular in offices and homes concentrate too much on simplicity not artistic
design."
HISTORICAL MATERIALS:
In addition to perspectives we are also
collecting historically interesting documents, photos, objects, and other materials
pertinent to electric lighting. Below are a few of the materials already received:
As of November 2000 we have received
several website referrals
CONVEYOR QUESTIONS:
#1 - Tell us about the designers, marketers, or other conveyors you believe have been
especially important in promoting energy-efficient lighting.
"Believe it or not, OPEC." "Charles 'Chip' Israel, Leslie Wheel,
Ralph M. Swarens, James Benya" "GE, Holophane, Lithonia, NEC and Hubbel" "I think the ballast designers and the lamp phosphor developers have played an exteremely important role in the evolution of fluorescent and HID lighting." "In my area of entertainment lighting,
I believe a prime mover has been ETC Corporation. They have designed a new generation
of fixtures that allow a 575-watt lamp to put out the [same amount of light as] a
1,000-watt lamp in a traditional fixture. Also, the advent of "intelligent" fixtures
that can move, change color, etc., by remote control has made it possible (in some
applications) to use fewer fixtures since these devices can be reset to perform the
duties of a larger number of fixed units. Two major manufacturers of this type
equipment are Vari-Lite, and High End Systems." "Many European manufacturers
and a few of their American associates who have evolved the use of low wattage
incandescent to create efficient and attractive fixtures. Such as Light Solutions in
the US and CEUP in Italy." Go to: Collecting
History from Conveyors #2 - Explain how the emphasis on lighting efficiency has changed the nature of your job
during the past 30 years.
"More efficient light strips are used now,
and our bosses care more about how they are using their money to light a job-site." "Though I have been in the lighting business for the last seven
years only I feel that, due to competition throughout the field, people have been compelled to learn about and use energy efficient lamps and luminaires."
"We are more careful to specify fixtures that are more efficient, and we are more careful to specify 'task' oriented lighting rather that a blanket of light." "The changing technologies in lighting
have forced designers to take a different view as to how they should illuminate a
space. A broad range of lighting has opened up in the last decade alone. Incandescent
lighting was the way when dimming situations presented themselves in the past.
Applications of the compact fluorescent lamp (CFL) were limited at first. As the
market opened up to the demand for more efficacious compact light sources, further
development of the CFL allowed greater flexibility for applications. Better phosphor
blends for better color rendering abilities have been developed, making integration
of the CFL into commercial designs easier. Though the compact fluorescent is more
costly [to buy] than a typical incandescent lamp, CFLs have more than paid for
themselves in the maintenance arena." "Another important development has been
the great improvements in control devices, especially dimmers. Up until 30 or 40 years
ago, these devices worked on the principle of introducing electrical resistance into
the circuit to control the lamp intensity. Thus even when a lamp was dimmed the same
amount of electricity was being used-the balance was dissipated as heat! Today,
electronic dimmers using silicon-controlled rectifiers and triacs moderate a lamp's
intensity by cutting off part of the Alternating Current sine wave, thus truly using
less electricity.” Go to: Collecting
History from Conveyors #3 - Can you give
examples of projects that have been especially important for moving efficient
lighting into the market?
"Major retailers and supermarkets seem to have been the first to specify both energy efficient and color corrected lighting to help sell their products" "India has been consuming
large quantities of general lighting service (incandescent) lamps.
Over last five years companies like Osram and Philips have created
awareness of the advantages of compact fluorescents over incandescent
lamps through various exhibitions and other media." "Retail is often considered one of the most energy inefficient users of lighting. However with the development of new sources and luminaires [retail users have] probably shown some of the most creative and aggressive adaptations of [efficient] lighting."

#4 - How
have the needs of various lighting users changed, in your experience?
Can you provide data on how you determined those needs and how this
influenced your planning process?
"There are various places here in Argentina
that simply cannot afford or don't have the resources (energy supply, etc.) to have
regular lighting. In these places I have designed systems using low voltage, energy
efficient lamps and on various occasions I have had to rely on careful alignment and
orientation as they could only afford little lamps. Energy efficiency here has
opened a new breach in costs and availability. In general, lighting users have become
more concise and are now more aware of what they want, which always makes it easier
to design."
"People are asking for more sophisticated lighting to replace standard incandescent and fluorescent. For example: halogen, low voltage and metal halide." "In the area of stage lighting it seems
that many more groups are utilizing live staging for disseminating their message,
raising funds, entertaining, etc. Schools (even at the elementary level) and churches
are two good examples of this phenomenon. Because many of them are relatively new in
this practice they are not saddled with hand-me-down equipment used for generations,
and thus provide a good market for today's manufacturers of modern energy-efficient
gear. Also, since many of these spaces don't have the raw power capacity of
traditional performance spaces, it is even more in their interest to get the most
light per watt of power."

History from Conveyors #5 - Lighting
design has moved from "blankets of light" to more refined and complex
designs. In your experience, have there been unanticipated consequences (good or bad)?
"My training has taught me that blankets
of light are visually boring and unacceptable. The more complex designs are much
better."
"In homes especially, task lighting and high-lighting have helped to make homes more inviting and attractive. However some complain there is not enough ‘ambient' light and the newer homes can sometimes feel dark . Some of this stems from the use of dark colors in newer interior designs" "Brighter in not always better. A drawback would be initial purchase price and possibly installation price of the newer lights. However, if by providing adequate lighting for the employees makes them more productive and happier, isn't the price worth it?" "The lighting knowledge in India is very low, but with multinationals like Thorn, Vossloh, Clipsal and others educating employees here even small organizations are compelled to keep up-to-date. This is a little difficult as we can not access as much technical detail as they can." "The market has budged, but not moved in
this respect."

History from Conveyors #6 - Can
you provide information about the effects of corporate downsizing and globalization
on lighting sales and design?
"Our downsizing hasn't had any effect on
our lighting as far as I can tell." "In entertainment lighting Rock n' Roll
seems to be the prime mover. It's music, theater, dance, and visual art-all in
abundance. And "nothing succeeds like excess", especially in America. However, Rock
seems to have become a global language and a lot of acts play Singapore and Sydney
like they used to play Kansas City or Manchester. This huge popularity has pulled the
technical aspects along with it (perhaps hand-in-hand), and today lighting trade
conventions go to Taipei or Buenos Aries, and equipment is manufactured or marketed
globally. The result is that entertainment lighting and all its attendant affairs are
of a worldwide mix with input from all over being redirected outward again to the four
corners. This pertains to sales, design influence, staging techniques, and safety
guidelines (as overseen in the U.S. by the United States Institute of Technical
Theatre). Corporate downsizing's most likely effect on entertainment would be that
corporate donations to local arts groups may become more scarce. This would affect
the performing group's disposable income for lighting as well as rental and sales
agencies, the labor and design pool, and ultimately the manufacturers."

#7 - Efficient
lighting is increasingly seen as a system involving many integrated components. From
your experience, how has this affected adoption of the technology?
"This is a great concept that has only
begun to crawl. I am currently working on a very complex project where we (lighting,
HVAC, security and IT designers) have integrated wide and local control of all systems
with cross-compatibility. The various industries involved have yet to recognize the
complexity of cross-compatibility and many say they have gone there, but have
[actually] only scratched the surface. Once the walls are broken down and the various
disciplines truly work together in development, only then will we see some highly
efficient and sophisticated technologies." "An open mind is required for the adoption
of anything new, as is the case of lighting technologies. Education in the new
[technology] is also paramount. If a designer is not well versed in the new
technology they will have difficulty trying to maintain an efficient design.
Familiarity with operational and visual characteristics of new technologies will aid
a designer in making the proper choice for [an] application while maintaining an
efficient design"
"I think it has greatly increased
[adoption of efficient lighting], now [that] more people understand what everything
is for and have less fear of importing new technology. Especially in transformers and
digital circuitry there is less fear of everything being too complex and [so] people
adopt the new technology."

- Describe how government actions have affected your efforts to expand the use of
energy-efficient lighting. These actions could include research and development
efforts, legislation, local energy ordinances, or buying habits.
"The Energy Act of 1994 coupled with Title
24 in California have made efficient lighting the rule rather than the exception."
"I applaud the efforts to save energy taken by the U.S.
federal and local governments. In Europe these efforts are admired." "The EPACT legislation, while well-intended
, has left some holes in my choice of lamps for ordinary household use. This is partly
the fault of manufacturers, who manipulate characteristics of their products within
the constraints of the legislation to allow them to advertise those products in the
most favorable light. For example, the old 150PAR38 [flood lamp], in its new, mandated
,120-watt form has a narrower beam to allow them to advertise it as having the same
photometrics. Consequently, we get less coverage and may even have to add more lamps,
thus defeating the intent of the legislation! While I applaud such efforts to save
energy and reduce pollution I hope that [legislators] don't get their hands on
special-purpose lamps such as stage/studio lamps. These are for special
applications and not for lighting chicken-coops, and besides, I feel the
manufacturers are doing a great job on their own."

History from Conveyors #9 - Energy-efficient
lighting is sold in four main markets: residential, commercial, industrial, and
specialty. How have design and sales perceptions of these markets changed?
"The sales end of the industry is lagging
a bit in discovering these newer and more efficient sources."
"There is a relatively high awareness of
energy efficiency in large commercial projects due to legal and cost incentives, and
to centralized buying through Facilities Managers, etc. This has not been the case
with residential and specialty markets where energy efficiency is seen as conflicting
with design and esthetics."
"Definitely most of the new residential and commercial projects have switched over to compact fluorescent lamps and more efficient luminaires, but the same is not true with industrials. They have remained more or less same." "The biggest problem is that energy efficiency has the connotation of increased initial cost. So where cost is a factor in the design of a project it is sometimes a hard sell, especially if the owner is not paying the electric bill." "Each market is different from the others
in terms of application. The users are now voicing their preferences and desires.
Before, all they could do was install whatever was available. "

#10 - How
does professional training about lighting differ now from when you started in your
field?
"Now there is training." "Not enough to make a great difference.
Most of my knowledge has been gained in my practice." "It has become all based on numbers and
engineering with a total disregard for aesthetics. What happened to a requirement in
understanding space and volume, human emotion and general architectural principles?
As a community, there is no longer a desire to render form and create spatial
excitement as much as there is the demand to produce calculations for the uneducated
who have no clue what a foot-candle means."
"As equipment types have proliferated and
control systems have gotten much more sophisticated, there is much more emphasis on
the technical aspects. Unfortunately, it seems that many if not most universities
train their students for a ‘best case’ workplace situation. While it may certainly be
desirable to introduce the student to all that is available these days, I wonder if
they're not graduating unprepared for a lot of ‘real life,’ less sophisticated
situations that are still out there-and will be for a while."

History from Conveyors #11 - Lighting
has been a part of many utilities' Demand-Side Management programs. Can you cite
particularly successful or unsuccessful efforts? What effect is utility restructuring
having on DSM?
"Florida Power and Light has a rebate
program for retrofit of offices from T12 to T8 technology. We
have only been able to take advantage of this program once unfortunately" "Successful implementation of utility DSM
programs has shown that greater quality and quantity of lighting can be achieved.
The fault, however, lies in the misapplication of retrofit technology by the Energy
Service Companies that receive revenue based upon energy usage reduction, mainly
derived from retrofit applications."

History from Conveyors #12 - Some
technically successful devices have failed to sell; other devices have sold well
despite technical problems. Describe your experience with such successes and failures.
"This industry is cost driven and the
decision to purchase occurs within a very competitive environment. This environment
is concerned only with present costs and not with quality or energy efficiency. And
for the sake of survival the industry has gone along. So, it is no trick to make the
best lamp or the best luminaire, the trick is to make one that will survive the
decision making process involved in the purchase. And that means to make the best,
most efficient [product] at a low price. "
"Who determines ‘technically successful?’
A number cruncher? Or a real world user? Great engineering does not mean you want to
live with it." "We don't care for low pressure sodium (LPS) light sources, the energy efficiency may be great but the color rendition stinks. The worst installation I've seen is in a town in Long Island that used LPS for street lighting; you couldn't tell the street lights from a yellow traffic signal - until it turned red."

History from Conveyors #13 - From

GENERAL QUESTIONS:
#15 - What
specific effects did the Energy Crisis of the 1970s have on your work with lighting
technology?
"It offered the opportunity to create more
sensitive lighting that related to individual users [rather than] corporate ease of
lighting management." Go to: Collecting
History from Conveyors #16 - Some
efficient lighting products have become associated with problems such as torchier
fires, mercury content, and "light pollution." What problems or concerns
affected your work with efficient lighting?
"Our biggest worry in India is that people have started replacing fluorescent with compact fluorescent lamps. Because of this the overall lux level has dropped drastically and that can effect eyes and the efficiency of people working under these lamps. People should be thoroughly educated about the product and the relevant requirements before launching such products." "The lack of controlling the source.
Initially there were no compatible fixtures for efficient sources. The void between
fixture manufacturer and lamp manufacturer has closed but continues to be a problem."
"The advent of reduced mercury fluorescent
lamps has and will continue to greatly depreciate the flow of mercury into the waste
stream. However the dutiful responsibility lies with the manufactures of these products
to inform consumers that there is still hazardous mercury content. One should not
think that reduced mercury content is not going to have an impact on the environment.
The less-is-better mentality is fine, but [even so there will be a] lasting impact
as the industry continues to add mercury to the waste stream. I hope that someday
the development of recycled mercury technology will experience a growth rate parallel
to [that seen in the] lighting industry."

History from Conveyors #17 - Adopting
efficient lighting seems to require producers, conveyors, and consumers to think about
illumination in new ways . Do you see evidence of new approaches to
lighting in society at large? Have you, as a conveyor, changed your
own notions about lighting?
"Yes, we as a producer have definitely changed our thinking but consumers are not taught the proper way to apply these products. Hence though they buy, they don't get the expected results. That disappoints them and keeps them away from trying such products in the future." "People respond well to dramatic lighting. More fixtures, less wattage, proper placement, convenient control - that's the way to go." "I believe that the population in general
has become more aware of lighting at some level of consciousness. I think that new
product development and aggressive marketing has [boosted] the dissemination of
lighting (not just illumination) into all areas of our society. This new awareness
can be found in restaurants, public and corporate buildings, museums and homes, as
well as in entertainment venues. I think this is also due to the good economy and an
increasing mood of consumerism. As we search for ways to dispose of our disposable
income, decorative-functional items such as good lighting are part of that mood. It
follows that, as a matter of personal economics as well as a growing environmental
awareness, energy efficiency would be a consideration in design and purchase."

History from Conveyors #18 - Has
your involvement with energy-efficient lighting led you to consider energy issues when you
think about other products? Can you give examples?
"I have experimented a bit with polarized lenses for fluorescent fixtures and think in some situations they help, but I have not seen a large enough application for polarized lenses to make a real judgement." "Yes. Air conditioning." Go to: Collecting
History from Conveyors #19 - In your
experience, has the environmental movement helped create demand for efficient
lighting? Can you cite any specific examples?
"Yes, to reduce the consumption of fossil
fuels for the production of electricity."
"India has yet to learn
on this subject as far as lighting is concerned." "No. The issues brought about by the
environmental movement are sound and good, but the consumer votes with the pocket not
the head. "
