Reply #31: Yep, all fluorescent lights emit a lot of UV. [View All]

The phosphor coating converts most of it from UV to visible light, but some UV still gets through. (I'm assuming it's UV light that triggers lupus flares.)

Would LED lighting trigger lupus? LEDs are insanely expensive right now (though the technology is constantly improving), but they're starting to be used for actual lighting purposes now, and they're very energy efficient. Also, the frequencies emitted by LEDs can be very precisely controlled, meaning that LEDs by design emit no UV.
