I would like to use LED lighting as backup lighting during power outages. I can work with 12VDC (direct from battery bank, so some voltage range must be tolerated) or 120VAC (from inverter powered by battery bank). I would love something with equivalent light output to a 60W incandescent bulb, but I'll accept something dimmer than that if that's the only thing on the market.
The sticking point is that I want it to have a CRI of 85 or higher and a color temperature of 4,000K or yellower. I currently have a Zebra Light H51Fc, which is a 85CRI 4kK emitter. It's just barely good enough.
Do high-CRI LEDs exist in the correct form for direct-replacement of a standard incandescent bulb?
