As LEDs Magazine reported back in 2017, a bunch consisting of the University of California system, the University of California-Davis California Lighting Technology Center (CLTC), and the California State Department of General Services announced its “Million Lamp Challenge,” in which the collaborative first sought bids to supply 1 million high-quality LED retrofit lamps. The original intent was to provide the University of California, California State University (CSU) and group college system, in addition to state companies with lamps that complied with the Voluntary California Quality Light-Emitting Diode (LED) Lamp Specification 2.0 printed by the California Energy Commission. In 2018, the program would be prolonged to faculty, employees, students, and alumni of collaborating organizations to buy the incentivized LED lamps. The lamps included have been common-service A-lamps.

Initially, that high quality commonplace was voluntary, but when it became aligned with the CEC’s finalized Title 20 Appliance Efficiency Regulations in 2016, differences of opinion arose within the LED and stable-state lighting (SSL) community as to whether or not the demands of the standard were focusing on the necessary metrics and a stability of efficacy and colour high quality. The concerns pared all the way down to whether the quality specifications took into consideration the efficacy penalty of shade characterization by CRI, and questioned whether the enactment would lower potential energy value financial savings and in the end the decreased carbon emissions goal driving incentivization of such ubiquitous products.

Fast-ahead to 2021 and the program members have now propelled what’s identified as the Million LED Challenge – Phase 2 into LED linear lighting replacements. The UC Procurement department just introduced two new contracted agreements to supply a choice of linear LED lamps (also called TLEDs), retrofit kits, and LED luminaires to exchange the installed base of fluorescent tubes throughout the partner institutions.
This week, LEDs Magazine spoke with Michael Siminovitch, Arthur H. Rosenfeld Chair in Energy Efficiency and director of the CLTC at UC Davis. Siminovitch is deeply involved with the Million LED Challenge and lighting analysis through CLTC. He additionally occurs to be a co-author on one of the linked articles regarding lamps high quality regulations, and has recently published via the CLTC webpage an article that outlines why California wants a top quality specification for linear LED lamps.
Curiosity piqued, we of course wanted to understand the synergies between the event of the Million LED Challenge for linear lamps and the quality specification proposed within the article. But first we needed to ask, what did the team learn from the original Million Lamp Challenge that could be utilized to the brand new linear LED lamps program?
“Basically, with the Million Lamp Challenge, we introduced that up initially to feed into type of broader promulgation, codes and requirements, availability, all utility packages, and many others.,” defined Siminovitch. “And [the response] was, mainly, ‘Well, we can’t do that because these items doesn’t exist,” he mentioned, clarifying that the university system and state contributors were concerned that high quality and value-efficient LED retrofit lamps products weren’t as extensively accessible as they should be. “So [they advised me], ‘You’re going to must convince your pals [in the industry] to go make these items before we start incentivizing it.’”
Siminovitch famous that via the framework of the Million Lightbulb Challenge program, the university companions, the CLTC, and its affiliates decided what benchmarks the procured LED lamps needed to meet in order to coach the general public on lamp specifications, motivate participation in the program, and deliver satisfactory outcomes. “Getting universities and neighborhood faculties and government buildings to work together is a difficult technical problem, and so we did eventually get [this system outlined] and it labored,” he said.
Still, “We obtained the expertise coming to the desk, and utility packages, after which the 2016, 2017, 2019 coloration normal – California type of took over on that,” he added, which introduced updated colour quality requirements into play for the lamp procurement. The Million Lamp Challenge helped to navigate the public through the lamps transition, Siminovitch famous. “You can’t purchase a foul lamp in California,” he noticed with a smile.
As mentioned earlier, there is a big base of linear tube lighting put in in the US. Siminovitch indicated that awareness of the better use of linear lighting across the college system. Government buildings propelled the necessity for Phase 2’s give attention to linear LEDs. But linear fluorescent tubes, ballasts, and fixtures introduced extra of a challenge than a basic-service, socket-base lamp alternative.
“At the same time [because the university requested the program enhancement], I’m getting all kinds of strain from schools and universities where retrofits are going badly,” Siminovitch stated. “Stuff is failing, doesn’t look great, you identify it. So I went to the Energy Commission and i said, ‘Look, there’s nice pressure to do stuff, but it turns out that we don’t have great expertise,’ in order that they stated, ‘We’ll take a look at it.’”
Siminovitch continued, “And sure, certainly, the technologies that have been going broadly into public buildings were not great – low high quality, low efficiency, that poor optics, you understand, after all poor color, interoperability points. So how did these experiences lead the Million LED Challenge partners to judge. Specify the linear merchandise listed in the procurement announcement?
Siminovitch initially objected to the proposal for TLEDs to be included in the program but understood that “you can’t stem the tide on that” as a consequence of value pressures and upkeep considerations in some services. However, the characteristics of UL Type A and sort B TLEDs have to be understood totally for the person installation scenario. Refer back to Siminovitch’s CLTC article for a concise rationalization of the advantages and disadvantages of TLED types. Performance and safety risks have to be assessed thoroughly due to interoperability points in Type A lamps with generally put in ballasts, and mains electrical voltage with Type B current on the fixture lamp holders.
“Of course, we’re trying to navigate in direction of [retrofit] kits; with kits we get actually improved optics and likewise longevity,” Siminovitch admitted. Regardless, “I stated we ought to develop a quality spec which might eventually evolve into utility applications and a typical for California. But let me use the public buildings purview – the colleges, the faculties, the federal government buildings – because the draw for doing a big public solicitation.”
When it got here right down to growing specifications for the linear LED lamps, he mentioned, “You want something that’s sensible and it’s not going to be massively costly, however one thing that meets the effectivity, the controls, the colour quality…You realize, simply the product high quality.”
Beyond the culling of preliminary submissions for pricing, Siminovitch defined, the merchandise wanted to be deliverable and manufacturers must present support, whereas sticking to producing TLEDs, kits with integrated LEDs and drivers contained in a plastic and metallic housing (a modular form issue), or a luminaire that can be mounted to the T-bar ceiling. “Most of the ‘action’ goes to be within the TLEDs and the kits,” he mentioned, and decisions may come down to the fee differential between TLEDs and the kits. “But there are places for TLEDs, a good-high quality TLED… Say, if you’ve bought a pendant fixture, an expensive indirect fixture.” As Siminovitch elaborated, “We really put in that the quality specification wanted to have a a lot wider distribution, to present volumetric brightness to an current fixture.”
We concluded our conversation with the prospects of bettering the retrofit expertise throughout a spread of business, academic, and governmental buildings, and how the SSL business can rise to the problem, as an alternative of enabling commoditization.
“At the end of the day, [individuals] actually do need quality product… And when you ask for it, and provides the industry time to reply, the price stuff… once you look at installation and shipping and ordering and all of the transactional prices – the fee differential here is insignificant,” Siminovitch defined. “Then if you amortize that over 5 to 10 years, you can’t even measure it. So why not buy one thing that’s good?” The conclusion to be drawn is that quantitative analysis of fastened prices versus transactional costs must replace assumptions that accepting lower-high quality product is critical to meet budget targets on giant-scale projects.
California rules, code, and policies have typically led the way in which for updates throughout the country especially in terms of vitality efficiency and environmental standards. It is going to be fascinating to see how the Million LED Challenge proceeds, together with the potential evolution of the program’s product specs into standards for commercially-obtainable SSL products.
