Cree has introduced an LED bulb that produces as much light as a 75 watt incandescent bulb, except it uses 82% less energy, translating to a reasonable power consumption of 13.5 watts.
This bulb is of the standard A19 type, it has a warm white colour temperature of 2,700K (for those fond of the flattering incandescent glow), and Cree claims it will last 25 times longer. The brightness is an adequate 1,100 lumens. A fluorescent bulb of this brightness would consume about 20 watts.
These bulbs are also dimmable, so people can set up a few of them to achieve a very high brightness per room if desired or needed, and they can simply dim them to save energy when the extra brightness is not needed.
As Cree said in a news release:
“Cree LED Bulbs are the ideal replacement for energy-wasting 75-watt incandescents and compromise-laden CFL lighting. Boasting the same shape and size as the popular A19 traditional bulb, the Cree LED 75-watt Replacement Bulbs can be placed in most lighting fixtures in the home. Unlike many low-priced LED bulbs, Cree’s omni-directional LED bulbs turn on instantly and are easily dimmable with most standard incandescent dimmers. The high-performance bulb is illuminated by Cree LED Filament TowerTM Technology and provides a compact optically balanced light source within a real glass bulb to deliver consumers the warm light they love and want.”
Lighting efficiency has come a long way, hasn’t it? It seems like just yesterday that light bulbs were consuming 75 watts. These efficiency and price improvements will be most beneficial to people who use recessed lighting, as such setups often involve separate light bulbs, so the cost per bulb has to be acceptable.
