I personally had an experience with a light of this sort. Rushing to go to the beach a girfriends daughter 6 yrs old rolled up a sleepingbag and put it in the top of the closet with one of these lights in it. The weekend beach house was about an hour away from her parents house where recently divorced girlfriend was staying. over the course of the hour the sleeping bag unrolled and layed against the lightbulb where it caught fire in the upstairs bedroom. Her 80 yr old father hopped up the stairs on 1 leg and put out the fire with one hand (stroke victim). All because the light was left on and the sleeping bag unrolled. I think of this everytime I put a closet light in. Everyone thinks it cant happen to them. Small price to pay noone got hurt.
