They missed the color, warm quality, longevity and dimming ability of incandescent bulbs.Īlthough CFLs have improved since their early days, those initial bad impressions stuck with consumers. The problem was, consumers didn’t fully embrace CFLs for their homes. In the early 2000s, CFLs became the poster child for the greening of America. (Karin Higgins/UC Davis) The problem with CFLs CLTC Director Michael Siminovitch uses his hands to compare the color quality of a lamp meeting the California Quality Specification (right), which the CLTC helped create, and one that does not. Perhaps the full-color experience will help spark new aha moments for the design students working under the lighting, while also conserving energy. LED lamps meeting the standard will be deployed in future relighting and new construction efforts at UC Davis, beginning with design classrooms as a pilot project later this year. The skin tone is warm, while the other hand appears more sterile.īoth bulbs are energy efficient, but only the second one displays high color quality - the one that meets the California Quality Specification. As a side-by-side comparison, one hand looks distinctly more, well, human than the other. He places one hand beneath a light in the first section of the box and his other hand under a light in the second section. Inside the center, Siminovitch stands before a divided box containing two light bulbs. With fully constructed mockups of hospital rooms, kitchens, art studios, a futuristic office, boutique store, and its own “bulb room,” it and the UC Davis campus itself are the testing grounds for lighting innovations that have spread throughout the state and beyond. The CLTC is tucked away in a quiet building on the eastern edge of Davis. “If we don’t develop the LED market right, we’ll run into the same problem.” High standards for high fidelity “Visual satisfaction and demand for the full-color experience is why CFLs failed,” Siminovitch said. The CLTC created the California Quality Specification to help ensure that energy efficient LED lighting doesn’t succumb to the same fate as compact fluorescent light bulbs, or CFLs. ![]() Effective this past January, new homes built in California must have lighting that meets the California Quality standard. Lamps that meet the standard are now available in the marketplace and are eligible for rebates. Such efforts support UC’s Carbon Neutrality Initiative, which commits UC to emitting net zero greenhouse gases from its buildings and vehicle fleet by 2025.Ī new lighting quality standard conceived by the CLTC called the California Quality Specification was adopted by the California Energy Commission in 2015. ![]() ![]() Many of CLTC’s recommendations become state building standards, creating a ripple effect of energy savings.Īdaptive lighting for parking and exterior lighting has been applied widely throughout California, including the UC campuses. When the center taps into a promising solution, its sound reputation has earned it the ear of lighting manufacturers and state energy regulators. UC Davis parking garage lighting retrofit. Fortunately, with new technology, we don't need to sacrifice one for the other.” Ripples of Light, and Energy Savings We’re trying to change that and meld visual quality and efficiency. “In the past, when we’ve moved to more efficient lighting, we’ve lost quality of visual experience. ![]() “Incandescent is a beautiful light source that we all love, but it’s not very energy efficient,” said Siminovitch, a professor in the UC Davis Department of Design. Now Siminovitch, co-director Konstantinos Papamichael and other researchers at CLTC are ushering in a new era of lighting that merges color quality with energy efficiency. It was his “aha” moment, leading his research firmly in the direction of restoring high color quality to energy-efficient lighting. Siminovitch said it was the most color-intense indoor space he’s ever seen. He was especially enthralled by its interior spaces: Reds, golds and earth-tones were illuminated by candle flame and warm incandescent lights, saturating colors to perfection. The temple was a highly crafted, architectural marvel, Siminovitch said. A Buddhist statue in Wat Chiang Man, a temple in Chiang Mai, Thailand.
