This is my first time using this lamps. My bed is a 88 model, Wolff system. 16 bulbs, once i replaced my old Wolff bulbs with this bulbs, i could instantly tell a difference. This bulbs are very very HOT! Use eye googles when laying in bed. My 3rd day laying with them, and yes i have burnt, they recommend to lay for 10 Minutes, i made a mistake and laid 10 minutes on the second day. Well worth the price.
