LED Bulbs







LED lighting has got a lot going for its advantages. The lights can be far more efficient than other types of lights, and the bulbs are supposed to last for tens of thousands of hours--enough to last 20 or 30 years depending on usage. Unlike CFLs, there's no mercury, the light is instant, and turning lights on and off shouldn't degrade their useful life, according to china led manufacturers.

The downside of LEDs, feature-wise, has always been the light color; the blueish light LEDs have traditionally had feels cold, particularly compared with the warm glow from incandescent and halogen bulbs. The other knock (or feature, depending on your usage) on LEDs has been that they direct light. That makes them great for spotlights but not good for a desk lamp. And LEDs for everyday use are pricey and unlikely to be stocked in your neighborhood hardware store.
However, all that is changing. Prodded by a federal mandate to boost lighting efficiency, consumer lighting companies are producing LED bulbs with the familiar screw-in bottom for general lighting. At this point, the amount of light that these LED bulbs produce is still a bit low, at least for my tastes, but the light quality is good. And of course, whether these bulbs last for decades as manufacturers say is still unproven.

Florida-based Lighting Science Group, which is providing many of the LED bulbs for Home Depot's EcoSmart line, sent me a package of its products to try out. Overall, I've been impressed and I'm looking forward to what comes next, particularly when you consider the pace of technology change.
Thomas Edison wouldn't recognize most of the products in the EcoSmart line; they are cone-shaped bulbs with fins that act as heat sinks, and they have flat tops where the light source goes. These are spotlights, great for casting a beam of light from above your kitchen counter or perhaps for an outdoor flood light.
In the past year, though, lighting manufacturers have introduced LED bulbs in a shape Edison would recognize that put out a decent amount of good-quality light. They still don't give off light from all sides as incumbent technologies do, but this latest generation of LEDs does a better job dispersing light, which means that you could use one (or a few) for overhead lighting.
