Last week I had a sudden revelation, and replaced the 60W incandescent bulb in my desk light with an 11W low energy bulb. Like most people these days, I have these bulbs fitted in many of the lights in the house. For some reason I never thought to put one in my desk light. It used to be too hot to touch within 5 minutes of switching it on, now it runs cool and remains easy to move around.
Yes, I know I sound like a bit of a dork putting that in my blog. :)
P.S. My desk light is an old original Luxo L-1, with a clamp rather than a base. My father-in-law gave it me when he rescued it from the office where he worked.
