Light fixture with LEDs of multiple different wavelengths
An LED light fixture comprising a plurality of LEDs mounted on a substrate, wherein the plurality of LEDs include a lime/mint light source accounting for at least 25% of the total lumen output, and a deep red light source accounting for at least 0.5% of total lumen output. The lime/mint light source preferably accounts for at least 50% of the total lumen output. The deep red light source preferably accounts for at least 1.0% of the total lumen output. The light fixture can also include other colors, such as 1% to 50% cyan, 1% to 20% red/red-orange, and 1% to 10% blue/indigo. In one embodiment, the fixture further includes a processor for calculating a color mix and driving the LEDs. Preferably, the processor is programmed to produce a color mix having a CCT in the range of 2700-6500K, a TM-30 (R f ) of at least 90, and a TLCI of at least 95.
