BEFORE WE REALLY GET GOING
• This presentation is based on my perspective and
mainly retrofit experience
– Glad that most clients really liked what I did
– But there are several projects I consider mistakes and
wish I would have specified them much differently
• You may have quite different perspectives and
experience and have found what works for you and
your clients
• But we can all learn from each other
– Including different
• Perspectives
• Successes & failures
4
BEFORE WE REALLY GET GOING
• Retrofit
– There are many good retrofit projects
– But there also way too many that just focused on energy savings
and paybacks, but the lighting quality and/or flexibility was really bad
• Wish I never delamped the 2x4 18 cell parabolics with repositioned
lamp holders, reflector and keeping the louvers in the one Kaiser office
many years ago
• In general, if retrofitters had to do their normal work in the spaces that
they specify the retrofits for, the design would often be much different
– Over the years several end-customers hired me to design re-retrofits, not to
save more energy, but to improve lighting quality and/or flexibility
– Too much lamp for lamp with reduced wattage T8s and low BF
ballast, which
• Does not really improve light quality
• Makes customer have to buy and recycle extra lamps down the road
5
BEFORE WE REALLY GET GOING
• New construction and gut rehab
– There are many very good projects
– But there are too many projects that have
• Way too many and often expensive lamp types
– Selecting a fixture for the looks, even though the lamp is not
specified in any other fixture in the project
•
•
•
•
•
Dimming ballasts, when really not necessary
Not the most efficacious lamps, ballasts and fixtures
Hard to access fixtures (to and into)
Complex control systems
Too high power density and electric bills
– Title 24 can be used as a back stop and every watt in a space is
used
» And Title 24 is worst allowable
– Check out following letter to the editor
6
BEFORE WE REALLY GET GOING
• LD+A published my letter to the editor in the December
2005 edition
– Reading October's Over & Out in LD+A, confirmed my
experience that very few lighting designers check with
maintenance and facility people two to four years after their
buildings have been built. If more lighting designers asked
maintenance and facility people what they think of the number of
lamp types, lamp life, lamp costs, accessibility inside fixtures, and
ease of maintaining lighting control systems, I think that many
lighting designers would change how they do design. A good
chunk of my retrofit business is from end users in buildings that
have good quality and energy efficient lighting, but the
maintenance costs are very high. I appreciate the business, but
would prefer if more lighting designers would walk a mile in the
shoes of maintenance and facility people in the first place.
7
BEFORE WE REALLY GET GOING
• Based on facility managers’ requests over the
years, retrofitters have gotten very good at the
following, especially over the last few years, when
facility and maintenance staffs have downsized so
much and 1 person now does what 2 or 3 people
did in the past
– Minimizing lamp types and eliminating expensive and
single source lamps
• An example is going with 2’ F17T8s or overlapping 4’ F32T8s to
get rid of 3’ F25T8s
– Specifying long life lamps often with program start
ballasts

KELVIN
10
KELVIN
• For offices, schools, etc.
– It seems like lighting designers and architects prefer
3000 or 3500K
• Because warm color tone and/or because think neutral
• Because of some of the lighting designers that were here in the
80s and 90s, higher percentage of 3000K here than almost
anyplace else
– While most energy efficient consultants and retrofitters
prefer 4100 or 5000K
• And love to see buildings with 3000 or 3500K, because know
can save extra wattage with using high Kelvin spectrally
enhanced lighting
• End customers pick 5000K in about 80% of my projects
11
3500K AIN’T NEUTRAL
• It is my experience, that many lighting designers and
architects consider 3500K neutral, because in between old
WW (3000K) and CW (4100K)
– And they would usually confirm that idea when they gave their clients
a choice of 3000, 3500 and 4100 Kelvin lamps with the same CRI
• But as I and other lighting professionals have learned, is that
when you give people a choice of three Kelvins, they
typically pick the one in the middle, so if you give them…
– 3500, 4100 and 5000 Kelvin, they typically pick 4100K
– 4100, 5000 and 6500 Kelvin, they typically pick 5000K
• In both phases 1 and 2 in the DOE research, there was no
statistical preference of lower Kelvin compared to 5000K
after 2 - 3 weeks, so who cares about initial preference
12
PICK KELVIN FIRST
• With 5000K, or other high Kelvin lamps
– Pick the Kelvin first and then look at paint,
flooring, furniture colors under that light before
they are selected
– It does not have to look sterile
• For example pick white paints with some warm color
tones
13
EVEN THE BEST CHANGE…
• Even the best change can be
considered bad, because some
people have to adjust
• So
– Inform
– Allow 2 – 3 weeks

NOTES ON 8000K
•
•
In the one 2x4 ceiling fixture in my office, I went from 4 F32T8 741s to 2 F32T8
850s to 1 F32T8 880
From Rod Heller, LC, Energy Performance Specialists, Wisconsin
www.energyperformance.net (July 29, 2009)
– American Family Insurance
• We are in the process of testing 8000K lamps for a major installation at American Family and
my contact at the company went to a meeting in a conference room and forgot his glasses. He
could not read the documents in front of him at the meeting, but sat through it until lunch. Over
lunch, he had maintenance change the lights from 735 lamps to the 8000K lamps. When he got
back to meeting he was amazed that he could read without his glasses. It was not as easy as
having his glasses, but he could read the documents.
– Goodyear
• I did a trial installation of the 8000K lamps in this facility. I took them 1 case of lamps and they
were installed in a couple of offices. By the time they got to the end of the box, people were
fighting over who got the last lamps. We then re-lamped all the offices. The one comment I
heard back was from the head of human resources. She stated this is the first time since she
had Lasik surgery that she has come to work and her eyes did not water. I have no idea why,
but it does warrant further investigation.

17,000K
• One major manufacturer has a new line of
lamps, available with 17,000K
• At this time more common in Europe
• 17,000K makes 5000K look warm white
19
WHAT ABOUT THE KRUITHOF EFFECT?
• IESNA Lighting Handbook, 9th Edition, 3-40&41
– Experiments examining the psychological effects of varying CCT and
illuminance have suggested that using lamps with high CCT values at
low illuminances will make a space appear cold and dim. Conversely,
using lamps with low CCT values at high illuminances will make the
space appear artificial and overly colorful. Figure 3-53 illustrates this
so-called Kruithof effect. Although these findings have been broadly
replicated, other investigators have failed to find a similar tradeoff of
CCT and illuminance. Rather they found that when people spent
sufficient time in the room for color adaptation to occur, the
perceptions of rooms lighted with lamps of different color temperature
was dominated by illuminance. This implies that where color
adaptation occurs with no opportunity to compare lamps with different
CCTs the CCT of the light source is relatively unimportant to
perception. Where comparisons can be made or color adaptation does
not occur, CCT is more likely to be important. At the very least this
confusion means that the widespread belief about the tradeoff of CCT
and illuminance should be treated with some skepticism.

WHAT ABOUT THE IES AND
SPECTRALLY ENHANCED LIGHTING?
• IES Visual Effects of Lamp Spectral Distribution Committee
– Chair
• Brian Liebel, who recently move from California to Florida
– Secretary
• Tom Tolen, who is in the San Francisco Bay Area
– Other local members include
• Dr. Sam Berman, people from the major lamp manufacturers, others and me
– Our TM-24 should be ready soon
• Before the IES accepts spectrally enhanced lighting
– I go below IES photopic footcandles if customer will sign off on it
• Except for critical areas like stairwells, carpenter shops, etc.
– I go for bottom of IES photopic footcandle range if customer will not sign off on
going below
• IES Board of Directors recently unanimously approved to revise PS-02-09
• Side note
– PG&E’s and some other utilities’ tool lending libraries’ have photopic scotopic light meters, which can be borrowed for free

T8s vs. T5s & T5HOs
• Yes, T5s & T5HOs are newer and smaller
than T8s, but are they really better than
T8s?
• Check out the following table, which is based
on optimal temperatures of 77F for T8s and
95F for T5s & T5HOs

T8s vs. T5s & T5HOs
• High performance T8 and T5 systems have about
the same efficacy
– But not that many people seem to be using the high
performance T5 systems
• High performance T8 systems are more efficacious
than T5HOs
– At optimal temperatures for each
• 22% than full wattage T5HOs
• 9% than reduced wattage T5HOs
– Special note for suspended indirect/direct fixtures with
lamps exposed in typical 70 - 75F ambient temperature
• 33% than full wattage T5HOs
• 14% than reduced wattage T5HOs
25
T8s vs. T5s & T5HOs
• Some fixture manufactures and others compare T5s and T5HOs to
basic grade T8s, generic electronic ballasts and fixtures with reflectors
and optics really designed for 5/8” diameter lamps
– Which makes T5s and T5HOs look artificially better
• I have heard that some fixture manufacturers, rep agents and
distributors push T5 and T5HO fixtures, because better profit margins
than T8 fixtures
– Since T8 fixtures have been around longer, pricing tends to go down over
time
• There are a lot more BFs for T8s
– Which helps fine tune light levels and wattage
• Mercury levels in T8s can be quite close to T5s & T5HOs
– Some T5s and T5HOs have more mercury than some T8s
• Since T5s and T5HOs are smaller, more can fit in a container, so most
of them are made overseas and shipped here
– Most T8s are made in America, which helps keeps jobs here

T5s & T5HOs
• Please do not spec the same length T5s
and T5HOs on a project
– Because down the road maintenance
people will probably put the wrong lamps in
the fixtures
28
U-BEND T8s
• Most end customers want to get rid of Ubend T8s, because they are
– Expensive
– Bulky to carry around
– Extra recycling costs
– Wattage can be significantly reduced with
F17T8s
• But numerous 2x2 fixtures are not long enough for
F17T8s, so new fixtures are required
29
PARABOLIC
TROFFERS
30
PARABOLIC TROFFERS
• Hopefully nobody here still specifies parabolics,
except maybe for niche applications
• But several manufacturers have designed very
good upscale kits from several manufacturers that
–
–
–
–
Allow delamping down to 2 or 1 lamps
Save substantial wattage
Eliminates the dreaded cave effect
Improves lighting quality
• I recently wrote a white paper that lists several
manufacturers
– You can request it by email

BASKET TROFFERS
33
BASKET TROFFERS
• These fixtures are often called indirect or indirect/direct
troffers, ceiling still dark
• Many architects and lighting designers have been
specifying these fixtures over the last few years, often
because of low glare, but
– Usually very low fixture efficiency
• Sometimes below 60%
– Often very difficult to get to the ballast
– These may be the parabolics of this century so far
• Although sometimes easy to delamp
– Sometimes can be difficult to retrofit, especially if biax or T5s and
too short for T8s
• Most end customers that I have dealt with HATE biax because
expensive, short life and not that good lumens per watt
34
BASKET TROFFERS
• This is what I recently did at San Jose State University’s
Martin Luther King Library
• Original
– 2x2 perf metal basket troffer with 2 40W 3000K biax lamps and
thin white lens on top of metal basket
– 72W
• Retrofit
– Although sides were shorter than 2’, there were round holes, so
F17T8s could be used
– 2 high performance F17T8s, high performance1.17 BF parallel
wired program start ballast, custom socket kit on outside of fixture
& custom high transmission white basket kit
– 38W
– Increased light levels, even just photopic
– $160 approximate cost

TASK - LOW AMBIENT
• Can easily get .4 - .6 watts per square foot in offices including
ambient and task lights
• Ambient examples
– High performance suspended indirect/direct fixtures with one T8 per
cross section
– High performance 2x4 kit or troffer with 1 T8
– High performance 2x4 kit or troffer with 2 T8s & .71 or .77 BF
• Task examples
– LED undercabinet and/or desk mount fixtures
• Optional occupancy sensor

Technologies Studies

– Would have even been lower power density with high performance

FLUORESCENT vs. LED
TROFFERS
• Based on DOE CALiPER testing there are some LED
troffers than compare quite well to high performance T8
troffers with regard to wattage, lumens and distribution
• But the LED troffers cost about $300 - $350, while high
performance T8 troffers cost about $100 - $150
• Also be aware
– When each LED troffer reaches 50,000 hours or maybe slightly
longer, it may cost over $200 to retrofit or replace it
– While T8 troffers can just get inexpensive lamps and ballasts
decade after decade
• Plus with present design, LED troffers will either provide
excessive light to begin with or underlighting at end of
rated life when LEDs lose 70% of initial lumens

LED
vs.
INDUCTION
40
INDUCTION
• Although one major manufacturer introduced induction in
1991 and another major manufacturer introduced their
version in 1997
– Induction has become quite popular over the last few years, mainly
from fixture manufacturers using lower priced Chinese and Korean
induction lamps and generators
• Real useable life for induction is really more like 60,000 70,000 hours than 100,000 hours
• Bare lamp system lumens per watt is usually
– <80 initially
– <55 at 100,000 hours
– And since a mature technology, probably will not improve much if
at all
• With such large coated lamps
– Very little optical control
41
LED
• LED fixtures have really improved, especially since last fall
– Efficacy
• There are some LED fixtures that provide over 100 lumens per watt out
of the fixture
– Price reduction
• Some LED recessed can kits now only cost $65 from distribution
• LED cobraheads, which can replace 100 - 150W HPS, can cost $300
when quantity is at least 1000
• Although some exterior fixture manufacturers are stating
over 150,000 hours for certain applications
– 50,000+ is more realistic
• Manufacturers are working on improved lumens for lower
Kelvin chips
42
LED vs. INDUCTION
• I recently wrote a white paper on LED vs. Induction
focusing on streetlights
– It is on my website with my other white papers
• When I visited a large LED manufacturer in North
Carolina back east earlier this summer
– Told that they will have 150 - 160 lumen per watt chips
by 1Q11, which will be able to provide 120 - 130 lumens
per watt out of fixtures at steady state temperature
• With LED’s continuing improvements and price
reductions, I think that
– Induction will be an afterthought in as little as 1 year
– And some end customers will have a hard time getting
warranty support and replacement parts, especially from
43
Chinese and Korean manufacturers

LIGHTING BLOOPERS
• One arm of a local government said
– We’re going to do some new streetlighting
– These cast poles will look super in our
town
• Another government office said
– This is a historic building
– The storefronts and the awnings need to
stay where they are
50
IF YOU ARE NOT
ALREADY AWARE
• There is a big push to try to mandate controllable
dimming or multi-stage ballasts in all new nonresidential construction in the 2011 cycle of Title 24
– Doug Avery at Southern California Edison
• Jim Benya is lead investigator
• Francis Rubinstein and Michael Neils are also in core group
• If this is mandated, it would take choices away from
you and your clients
• But may bring pricing down on these ballasts and
controllers
51
IF YOU ARE NOT
ALREADY AWARE
• Since I consider this very ugly, I spent a lot of time,
focusing on the California Energy Commission, to
stop this mandate, because often about the same
or more wattage and KWH can be saved other
ways for much less initial and long term costs and
are more sustainable
• Since this is so important, you and your
counterparts across the State could provide your
input for or against
