A sunburn on the human skin can occur with 500 micro watts/square centimeter of UV. Some cheap HID bulbs have been tested to produce twice that amount of UV light. The OEM bulb suppliers seem to be able to keep their UV outputs in the 200-300 micro watt/CM^2 range even on the higher color temperature bulbs.

Big whoop, a headlight lens is supposed to be a bit more resilient than human skin....and as to sunburn? Y'all planning to tan yourselves leisurely sticking your face in front of the housing???
Hate to disappoint, you'd have to lay down for that, else the only thing your E90 LCI headlight will be hitting point blank is the knee and shin area of the pants of a person standing in front of it.
And, on another note, youre not supposed to use reflectors for HIDs period, so if it burns reflectors like you say youve only got yourself to blame
