Michael Doran Posted July 28, 2015 Report Share Posted July 28, 2015 I was intrigued by the idea, so I called my UV lamp supplier. (Currently I'm using a mix of UVC and UVB fluorescent lights for tanning and UVB for drying varnish.) He and I had a great conversation about LEDs in general as well as UV LEDs. The tests he's done showed that that the LEDs on the market today are not actually emitting very much UV, nor was he convinced that the proposed nanometer ranges are necessarily accurate. He also told me that, in general, for a comparable amount of light emission (lumens) LED and fluorescent are about neck and neck in terms of energy efficiency. A particular LED or fluorescent tube could be slightly more efficient than the other, but he said it's mostly a wash. To be clear, both are drastically more efficient than incandescent. He thought the real draw to LED is the longevity, not the efficiency. He said that to try and rig up a comparable set up to what I have in my light box with LED would be very expensive, about as efficient, and not emit nearly as much UV.
