Next time that old incandescent bulb goes out in your trouble light try replacing it with one of those compact fluorescent types "CFL". I put one in my trouble light over two years ago. I have dropped it 100's of times & the same bulb it still going. You can put in a 100 watt CFL for only a few pennies & it doesn't get hot either, no more burns on your face when you get a little too close.
