Led Light Bulbs How They Work

This generates energy which is released as a "photons" — units of light. While they currently cost more than ordinary bulbs, LED light bulbs can last 25 times longer than traditional bulbs. Traditional incandescent bulbs only convert around 10% of their A group of girls sat listening to a breakdown of how circuits work in place and slide the LED bulb's wires inside to make a connection. The girls then used tissue paper to create the leaves and petals of the flowers, before they turned out the lights In my Times column Thursday, I reviewed a new generation of LED light bulbs. They last 25 times as long as regular bulbs, use maybe one-eighth the electricity, work with dimmers, turn on instantly to full brightness and remain cool to the touch. And LEDs are even more efficient, and last longer to boot. Yes, they’re pricier, but LEDs are vastly superior to CFLs in every other way. But which LED bulb is best? I experimented with a few brands to see if I could suss out differences. To compare That’s because, although they’re Many LED bulbs are dimmable, but older dimmer switches were designed for use with incandescent bulbs and some won't work with LEDs. If you're unsure about your dimmer switch, visit light bulb manufacturer websites a traditional 60W bulb you need just a 6W LED bulb. Although they are considerably more expensive to buy than traditional light bulbs and other “low energy” types of bulb, such as those that work more like fluorescent lights, they consume so much .

There are many reasons that LED light bulbs continue to be popular. Here are some of the main benefits they offer: LEDs are extremely efficient and require very little current to illuminate. Since they do not have a filament, LEDs do not heat up Cooler than an incandescent, but still hot to the touch Both the Ecosmart and Phillips LED light bulbs get quite hot during operation. They have circuitry inside and that circuitry does dissipate heat. It’s warm enough to prevent holding for very long. A bit more on economics: an Edison bulb so LED bulbs are usually rated for 25,000 hours. How long they last in practice is TBD, however: I have not used any for 25,000 hours. Edison bulbs are good for about 2,000 hours. Here is how the dollars work In some ways, LED light bulbs are a perfect technology. But they still have a way to go before they become the higher-efficiency bulb of choice. In this article, we'll find out why. We'll look into how they work, why they're a desirable lighting choice .
