I bought this up-lighter almost 20 years ago in B&Q. Back then it was fitted with a 500 watt halogen lamp, which was an expensive proposition even back then, so the light wasn't used much. I finally got round to modifying it to take a state-of-the-art LED G10 lamp using a recycled lamp fitting. It is just as bright as before and now uses... 4 watts! That's a 125th of the electricity for the same light output. The cable is a bit heavy and I want to make sure the connections are 100 percent safe and secure before bringing the light into the house, but it works.
