Sylvania has been making energy efficient light bulbs for a long time now with an excellent selection of compact fluorescent bulbs. They've recently kicked it up a notch with a new line of LED light bulbs; the ULTRA Retrofit line, made with medium bases for direct incandescent replacement.
The ULTRA LED Retrofit line of LED light bulbs replaces a variety of incandescent light bulbs. The standard light bulb shape everyone is familiar with is called A-line, and the ULTRA LED Retrofit A-line LED light bulbs look great. It is an 8 watt LED light bulb
designed as a high quality replacement of 40 watt A19 size incandescent bulbs.
For smaller applications there is the MR16 LED light bulb. This is a 6 watt bulb designed to replace 20 watt halogen MR16 incandescent light bulbs; the type of bulbs you would use in track lighting or to light display cases.
They even have a flood light LED light bulb! The ULTRA LED Retrofit PAR
line of lamps replaces incandescent floods, including sizes PAR20, PAR30, and PAR38. The number after PAR indicates the relative size of the flood light. PAR20 LED light bulbs are 8 watt and replace 50 watt halogen equivalents. PAR30 are 15 watt, for a brighter 50 watt halogen replacement. Finally there is the PAR38, weighing in at 18 watts and suitable for replacing 75 watt halogen PAR38 lamps.
This is a pretty exciting development in the lighting industry, as now all the other players will need to quickly release comparable lines of LED light bulbs! With all the competition this will create, prices should continually go down and it won't be long before we're all using the next generation of energy efficient, green light bulbs.
