I made a small but significant improvement in my workshop this weekend. For a number of years I have been using a series of clip-on task lights that allow me to "point" a 100-watt bulb at the area or tool on which I am working. I usually clip the lights to the rafters above my head and point them directly at my work. I sometimes I use two or more of these lights at once (like when I am using the lathe).
The lights have always worked great, but I always end up breaking a sweat from all of the heat that they generate just above my head. This weekend I replaced the regular incandescent light bulbs with 100-watt equivalent compact-fluorescent light bulbs. The compact-fluorescent bulbs generate almost no heat and are every bit a bright. Plus they use 47% of the energy and last 10 times longer than the regular light bulbs. Nice change.

A Learning Adventure in the Workshop 
I am a big fan of compact fluorescent light bulbs. In my home, I have replaced all of the incandescent light bulbs with compact fluorescent bulbs. The power savings is significant.
What happens when a compact fluorescent bulb burns out? For an incandescent bulb the filament burns up and breaks. No fire hazard. Well, about two months ago I had a compact fluorescent bulb physically burn out and started to smoke and just about ready to catch fire! Fortunately no damage was done.
