I tried making a lamp for my observatory consisting of an 11 watt halogen light and a red Perspex cover,which could fold down, giving me a red or white option. The problem was the heat given off by the lamp, it started to melt the perspex.
At a fair increase, pricewise, I replaced the halogen with a 1 watt LED which had the same fitting. What a change, bright light and cool, and, only 1 watt. That is the way to go!
