These are an order of magnitude more efficient than compact fluorescents. Improvements in these have been made in recent years so that a greater selection of fittings and a brighter light is now available, but bright ones for regular practical lighting are still very expensive. Moderately priced ones are useful for low level decorative or emergency lighting. There is no extra cost for colored ones, and color-changing ones are becoming more popular for special effects. Whereas CFLs use about one-fifth of the electricity of incandescent lamps, some LEDs use one-tenth to one-fifteenth. I would expressly consider using them as GU10 halogen replacements, providing bright light is not needed. A sensibly priced GU10 replacement LED will give the equivalent of 20W of light, but only use about 1.5W electricity.
