Cheryl and I have been selling woods lamps for many years at our www.woodslight.com website. All of the lamps currently on the site use fluorescent lamps with a wavelength of 365 nm. Over the last few years there are more and more solid state UVA black lights showing up on the market and most if not all of these emit 390 nm (longer wavelength UVA).

I'd like to know if these LED lights can be used to detect Vitiligo. There is no doubt that areas of skin glow (fluoresce) brightly under UV light at 365 nm. The question is "Will light at 390 nm cause skin to fluoresce?"

I want to find out and the first two or three souls with Vitiligo (living in the USA) who email me at chris@cane.com will receive a sample of a UVA Flashlight at 390 nm. I'd like to chat with you and figure out the best way to test the newer technolgy lights.

Here's a photo of someone with Vitiligo using a 365 nm light.

I'm wondering if we get similar results with 390 nm light?

Call me 877-289-2656 or email me at chris@cane.com

Mayb you can help!
