Meyda Custom Lighting Creates Custom Victorian Chandelier for Traverse City Opera House
SSLighting Design News Staff
March 5, 2010...Dr. Timothy Hanley and his wife Sally chose to donate a chandelier to the Traverse City Opera House as part of a major restoration project. The Traverse City Opera House was the first public building in Traverse City to feature electric lighting. The opera house, which was built in the 1890s in downtown Traverse City, is now a cultural hub in the area.
Meyda Custom Lighting of Yorkville, New York was contacted to custom design and manufacture a one-of-a-kind fixture. Meyda Custom Lighting is a Meyda Tiffany company and a leading manufacturer and designer of custom lighting and decor.
The original Victorian-style chandelier, which featured Vienna glass globes powered by gas, was lost long ago. No images of the fixture were available. The new chandelier was based on a conceptual design prepared by the opera house's restoration architects, Quinn-Evans of Ann Arbor, Michigan. The design represents an historic interpretation of lighting fixtures that were in use in the late nineteenth century.

Commentary & Perspectives...
Breaking SSL barriers... and ratting out the fiends
Tom Griffiths - Publisher
March 5, 2010..."Records are made to be broken," quotes the old adage, and it is never more true in vibrant technology areas such as LED lighting. Two of solid state lighting's 'technology barriers' have recently been broken with a recent announcement from Cree of lab results for 200+ lumen-per-watt (lm/w) from a power LED, and from BetaLED with new 100 lm/w exterior soffit luminaires. While barriers may be just a another number, they also have significance to humans because they build belief. In some cases, it's belief that a particular task really can be accomplished. Sir Edmund Hillary succeeded at climbing Mt. Everest, and now about 150 people reach the summit of that mountain each year. In other cases, it demonstrates that a barrier is not a physical one, but a mental one. The four minute mile was deemed by many to be "unbreakable" due to human physiology. "Not enough capacity to absorb oxygen, and it's simply too long a span to maintain that anaerobic condition," was a common argument. Then in May of 1954, Roger Bannister broke the barrier. While that was a huge accomplishment, even more stunning was that it was broken a second time by Bannister's closest competitor, John Landy, just six weeks later. This wasn't a one-off miracle performance. The barrier wasn't a physical barrier, but a psychological one. In classic "did it second" form, Landy took the approach that "it wasn't really a barrier" at all and contended that, “It has nothing to do with psychology," he was quoted as saying. "It was just a matter of having the right runners at the right level of training and the right set of circumstances." Meanwhile the "barrier" had stood and been argued-over for over decades, while human physiology hadn't gotten better. People had simply been training to get as close to the 4 minute mile as possible, but not necessarily to get under it. Once the "barrier" was broken, perceptions changed to "how much below it can we get. Once there were at least two believers", 9 or 10 managed the feat in the next 24 months with the new records continuing to be set 18 more times from 1955 to 2000!)
It wasn't that long ago when some were suggesting that 200 lm/watt would be close to all we could expect out of a power LED source, and I remember charts showing LED efficacy showing a real asymptote kicking in around that 200 lm/w. The DOE's LED lighting roadmap has actually been adjusted at least once to reflect the efficacy growth curve exceeding the time frames that the industry originally expected. When asked for some thoughts on "the barrier", Cree's New Business Development Director, Mark McClear commented that, "By hitting that mark, I think it has been pretty clearly demonstrated that there is still more room to grow. Breaking this 'barrier' clearly establishes LEDs as the most energy-efficient artificial light source." Cree has been very reliable about turning "lab results" into production-available products in a12 to 18-month time frame.
The second recent accomplishment was breaking that 100 lm/w "barrier" at the luminaire level. I suspect that Beta isn't the first to claim the accomplishment, but I do know that they have been one of the consistent performers in the exterior SSL lighting space, and are probably the most visible brand in that segment. And if they said it, that we can expect it is true. While 100 lm/w doesn't suddenly shift the business case in comparison to 96 or 98, it is easy to recognize that "more than 100" is something that the industry can latch onto in order to stake claim to offering the highest efficacy solutions. “Our achievement of reaching over 100 lumens-per-watt delivered in outdoor LED luminaires demonstrates the advantages of LED technology over HID,” said Christopher Ruud, president of BetaLED, a division of Ruud Lighting.
Hopefully what will be memorable here is that the 100 lm/w mark is being achieved
'on the target'. As Ruud explained, “Lumen-per-watt ratings on traditional
lamp sources are misleading because they don’t account for inefficiencies
of the ballast, reflector or lens. Lamp manufacturers have claimed 100 lumens-per-watt
with conventional light sources but this was not a measure of total lumens exiting
the product. While HID technologies reached the 100 lumens-per-watt mark
at the lamp, i.e. bare source, the light output was not directed in a useable
fashion. Up to 40 percent of the bare lamp’s output can be lost to
ballast, reflector and lens inefficiencies. BetaLED integrates LED chip
technology with optical performance and an optimized fixture design to maximize
light output at the source and on target. This delivered, targeted-lumen output
is the most efficacious luminaire to date, and further proof that an LED is
the most efficient light source in the industry."
I think Mark summed it up nicely with a thought on the ultimate relevance, outside
of this or that number. "Raising the performance bar in brightness and
efficacy is really about economics. Each advance in LED performance lowers LED
lighting product costs, opens new markets and applications and brings the LED
Lighting Revolution to more and more people." The performance continues
to march forward regardless, but I believe the fact that these 'barriers' have
been broken will really lock into people's minds that "LED lighting can
do it".
Time to start calling out the violators?
In my marketing life, I have never been one to focus others' attention too much on what the competition is doing, generally preferring to simply "outperform and ignore them" rather than make more direct accusations of their exaggerations or 'specsmanship'. That admittedly colors my thinking to create some distaste on those that might take a different approach. But things have changed, I believe. For the LED lighting market, as LED efficacies come up, new entrants are better able to claim that their luminaire, or their "integral replacement lamp" if it is an LED bulb or LED tube type of design, is a cost effective replacement for an incandescent, fluorescent or HID source. The specs make the case, and while in the past, if a company was claiming 50 lm/w but only putting out 40, it didn't really matter all that much since no rational decision maker was going to choose their solution compared to a fluorescent or HID incumbent except in a few specialized cases. Generally, when you have a specialized case, extra diligence is required and the truth will be uncovered in short order. A bad apple doesn't have to ruin the whole bushel in most of those real-world circumstances.
But as LEDs really do become recognized as the most efficacious source out there, the risk to the industry is increasing. The decision maker sees enough luminaires from reliable suppliers to be putting out 80 lm/w and more, so it starts to sink in that such performance isn't the special case that it once was. As their guard comes down, so does their risk aversion and skepticism. They test a few top notch suppliers, and find those suppliers are meeting the specs they claim. "Looks like the claims are reliable," they say to themselves. Then along comes a supplier whose name has been out there, and who is claiming a spec along the lines of what the decision maker has seen, with the addition that the "new guy" is showing a substantial cost savings. Makes sense... the two progress curves are "increased performance at the same price" and "similar performance at a lower price" especially from lower-overhead and potentially more agile new entrants. Problem is, the manufacture is lying, or using inferior materials, and with the decision maker's guard down, it may not be discovered until hundreds of units are installed (especially if they are replacement lamps). The industry gets a black eye.
So what should be do? Our suggestion is that maybe it's time to reset the industry's "politeness meter" to be oriented towards protecting the customers, and start calling out the blatant violators. At least one resource for that is in the Energy Star realm. Recently, we even let one slip through, as a company that signed up as an Energy Star "partner" projected the story that it was due to its product performance. "Partner" says "we want to support the Energy Star program" not "we have Energy Star qualified products". And Energy Star is pretty clear on its policies. "Partner" can't be used to imply the products are Energy Star approved, whether the mistake is made intentionally or not. There's no fine print about it either. Personally, I think the Energy Star "brand" is well enough established that the use of the phrase "partner" should be scaled back to include only those companies that have at least one product that is actually certified for the mark. They may have other products that aren't there yet, or for which a category doesn't exist, but having at least one would probably take us 90% of the way towards eliminating the problem, both because ignorance would not be an excuse, and because violation of how "partner' is used would put the company at jeopardy of losing their Energy Star approval on a product that they invested effort in getting the mark attached to. We are advocating that violators be reported. If you see what you believe to be the improper use of the Energy Star Partner mark, or see claims of an LED replacement lamp as being "Energy Star qualified" (the specs don't kick in until August), you can and should report them to ssl@energystar.gov.
