Unlike CFLs, LED Lamps contain no mercury. For more on Fluorescent lamps and mercury, see end-of-life management and Mercury in Fish .
The Operating temperatures Manufacturers specify on packaging should also be noted.
Light Emitting Diodes (LEDs) are the new source of Energy Efficient Lighting. LEDs provide more light for less energy. LEDs also last a long time.
LEDs have been around for a while. Their low energy use has made them particularly valuable for heavy/extended use, emergency and portable lighting. Where you want the light to last as long as possible on your battery or other form of emergency power supply. LED emergency lighting is used in Aircraft and in domestic torches and fire alarms.
Low voltage (typically 12V) ropes of LED fairy lights, Solar Powered garden lights and strips of LEDs have enabled creative lighting of domestic spaces, for sometime. In recent years, LED direct replacements for standard fittings have appeared on the market. In addition to requiring less energy to provide more light, LEDs are also available in Dimmable and for use with movement detectors to provide active lighting.
There are LED direct replacement alternatives for 
12V DC Two Pin Halogen - MR16 GU5.3(pins) 290lm or 240V MR16 GU10; 240V AC E15 (small edison Screw for multi-globe light fittings); 240V AC E27(Edison Screw) and B22 (Bayonette); T8 Fluourescent Tubes and Flood Lights.
While this guide focuses on Energy use and source (voltage and fittings), these are not the only considerations in selecting lighting. The type of lighting required is also a consideration - warm white, dimmable, white, other colours, low light, safety lighting etc. New LED products are emerging which provide the opportunity for new ways of lighting spaces.
The Operating temperatures Manufacturers specify on packaging should also be noted.

31 October 2013: Philips and Osram Lamps plumet in price as does the predicted lifetimes. Philips 10W B22 220-240V LED Bulb rated at 806 Lumen and 15000 hours was priced at just $15.98. When unpacked the Philips lamp looked like your old fashioned incandescent bulb! It was installed in a kitchen.
A 13W Philips LED Lamp claimed to be the equivalent of 75W incandescent. A 9W Osram was even cheaper but only put out 600 lumen. Both claimed to be equivalent of 60W incandescent. | |

27 December 2012: Phillips myvision LED Lamps are finally on the Shelf!Philips E14 Candle (4W Warm White 250 lm) was shorter than the Osram E14 Candle though both were larger than the Osram Halogen E14 Candles. Two Philips E14 Candles fitted into one Fan/Light fitting where the Osram model was too big. Two Philips B22 (9.5W Warm White 600lm) fitted into a Fan/Light with a larger lamp cover. Price $20. It is worth noting that the light fittings were rated at maximum 25W lamps and the halogen lamp was 28W. So, before installing such fittings, care should be taken to ensure they will allow enough lighting in the room. |
