The latest technology in LEDs provides Museums the opportunity to get comparable good color rendition, and art conservation as an incandescent source, and contribute to the global efforts of sustainable lighting.
The San Francisco Museum of Modern Art (SFMOMA) experimented with newly installed LED lighting fixtures in the Djerassi Gallery.
The existing Djerassi Gallery at SFMOMA (picture on left) was being lit with a quantity of 25 fixtures using 45 watt Halogen PAR38 lamps with 45 x 50 degree spread lenses achieving a fc level between 7 and 9 fc for conservation purposes.
The same Djerassi Gallery at SFMOMA (picture on right) was re-lit using a quantity of 17 LSI LumeLEX 2040 Series LED Fixtures utilizing Xicato technology 2700K 95+ CRI, a 40 degree reflector with a linear diffusion gel and a 30% neutral density gel.
RESULTS:
25 fixtures were replaced with 17. The light levels and uniformity were virtually identical at between 7 and 9 fc. 1125 watts of incandescent light were replaced with 442 watts of LED light. That's a 61% savings on direct energy alone. In addition, there is roughly a 1W reduction in HVAC load for every 3 watts of reduction in lighting load, so the reduction of 683 watts in that gallery alone would also contribute to an additional 227 watt reduction on HVAC.
