The incandescent light bulb is a past tense, already gone from shops in Australia and Brazil. By the end of 2011 their sale will be banned in Britain, production ended in Japan and fadeouts will begin in the United States and intensify across Europe. Many are switching to compact fluorescent bulbs (CFL) that still contain harmful mercury and do not last as long as LED bulbs. Why switch to 30 watt CFL when a 6 watt LED will do the job? Welcome to the new light, LED bulbs are dimmable and come in PAR38, MR16, and traditional A19 incandescent sizes and equivalent fittings. Incentives are now available to help cover the extra cost for LED bulbs.
| MR 16 | 5 Watts |
| PAR 38 | 10-16 Watts |
| A19 | 6 Watts |
