It must throw down some strong UV rays...because I was rotating plants with the light on and developed a rash/burn on my knuckles. First my right hand; (didn't know what it was, causing it)...then I switched hands and got rash on left hand knuckles......bottomline: don't stick your hands into the light....:smokin:

Anyways...I think most MH bulbs throw down serious UV rays, that's why many are rated for inclosed fixtures only. To block excess UV rays. This bulb is rated for open fixtures and has SOME UV block built into the glass bulb...but not much.
