This 20 watt Lightwiz is suitable to replace a 60 to 75 watt incandescent. The bulb is rated to last for 10,000 hours. The spiral design ensures even light distribution on all sides, and the relatively low purchase price ensures a quick payback.
This bulb is not suitable for use in enclosed fixtures, emergency exit lights, in outdoor locations where it would be exposed to the elements, or in conjunction with dimmers or photocells.
