Electric Miniature
Are long-life (low-energy) electric light bulbs hotter or cooler than old-style bulbs?
Which kind of electric Light Bulb gives out most heat for the equivalent amount of light – one of the old (UK) bulbs or the newer low-energy bulb? I believe the low-energy type are just miniature fluorescent lamps, so in theory they should be cooler.
But I want to check on this before using these in a lampshade.
My free Yahoo bulb is much cooler.
