Demystifying LED Lightbulbs > 자유게시판

Maybe you’ve already executed the righteous factor and swapped out all your power-sucking incandescents and not-universally-useful CFLs for long-lasting, mercury-free, power-saving LED bulbs. More doubtless, you’ve dropped in a couple of right here and there, with blended outcomes. LED bulbs can still be chilly, alien-wanting things with odd shapes, splayed fins, and dazzling price tags. But they keep getting better-and EcoLight cheaper. Should you haven’t already, now is the time to start making the switch, and we’re going to explain how and why. The first LED bulbs I tried made my living room seem like a hospital ward. How do I avoid that stark white gentle? Newer fashions do a greater job of diffusing the tiny directional beams that LEDs generate. But even so, you may want to begin with decrease-lumen (which means much less bright) bulbs. LED bulbs-which home digital circuits and light-emitting diodes that act as semiconductors relatively than filaments-now come in "color temperatures," together with warm tones that may mimic incandescent bulbs and flatter furnishings, comparable to varnished wooden.

Curiously, cooler ones are sometimes really useful for outdoors as a result of they carry out the inexperienced in foliage, says Seattle-based lighting designer Christopher Thompson. There’s enough small print on the bundle to blind a lawyer. Look for the requisite Lighting Facts label, EcoLight solutions which posts the Kelvin (Ok) rating: The nearer to the lower end of 2700K, the warmer the sunshine (yes, that does sound backward). Bulbs are additionally rated for his or her skill to render color accurately, reduce energy consumption utilizing what’s called the Colour Rendering Index (CRI). Incandescents, reduce energy consumption which do particularly properly with hotter colours, rating 100. It's possible you'll have to verify the manufacturer’s webpage for the CRI ranking; despite all that small print, it’s not always on the package deal. I’m confused about watts and lumens. Life was a lot simpler when i could change one 60-watt bulb with another! Lumens are a greater means to compare brightness. Watts measure how a lot electricity a bulb attracts, EcoLight lighting not light output, which varies, since not all 60-watt incandescents are equally efficient.

More necessary, 60-watt-equivalent LED bulbs could seem brighter, since the light is cooler. So if you’re purchasing for a 60-watt equal, consider making an attempt a 40-watt equal instead. Its 450 lumens could also be brilliant enough. I really like my recessed cans however can’t find an LED flood that has a broad, heat light. Look for a reflector bulb, such as the BR30 type, with a slight bulge near the face of the bulb. Data on the package deal ought to say whether the bulb is a "spot" or a "flood," and reduce energy consumption may additionally include the angle of the sunshine beam. When you desire a flood, search for EcoLight dimmable an angle of greater than 50 levels or the acronym WFL, for broad flood. Alternate options for recessed cans also embody LED floor-mount panel fixtures, such as ones made by Pixi Lighting. One other downside: The dimmer is not in a position to carry the light manner down. Traditional dimmers are often unable to operate LED bulbs: They might flicker or fail to reply-a syndrome often known as "dead travel." In other words, don’t assume a bulb labeled dimmable will jibe with the dimmer you’ve received.

Go to the bulb maker’s web site to see which dimmers go along with which bulbs-or consult the Lutron LED Control Center of Excellence, which runs a toll-free hotline for frustrated customers: reduce energy consumption 877-DIM-LED8. Smartphones may become the ultimate resolution; Philips already makes bulbs whose color and brightness are managed by an app. Can I stick an LED bulb in any fixture? Pretty much. Just match up your previous bulbs’ bases with LED variations, taking care to also compare lumens, or brightness levels (again, a lower-lumen bulb could also be extra pleasing). Some new bulbs are surprisingly good at mimicking the familiar Edison, reduce energy consumption and reduce energy consumption one company, Change, has launched the primary three-way LED bulb. To soften the beam and make it much less direct, manufacturers set up a number of LEDs, reflectors, lenses, and EcoLight brand diffusers within the bulbs. Some bulbs look slightly funny until you turn them on or put them behind a shade or inside a glass globe. However remember that some LED bulbs cannot be used inside enclosed fixtures or capped recessed lights.

As Ray Johnston, a workers scientist at 3M, explains, LED bulbs have "heat sinks"-fins or one other means out for the heat generated when power passes via the semiconductors-which assist them use much much less wattage and emit a lot less heat than incandescent bulbs do. But on the flip facet, LEDs are extra sensitive to their surrounding temperature and want a decent quantity of airflow to work effectively. Overheating won’t make a bulb explode, but it will shorten its life. As for cold temperatures, in contrast to CFLs, LEDs do nice outdoors. How about replacements for unusual bulbs? Look for LED pin bulbs that may replace halogens, small bulbs for candle-style fixtures, and specialized LED fixtures, such as undercabinet strip lights from companies like Kichler and Häfele and battery-operated lights for drawers and closets from the likes of GE and IKEA. Remember the fact that the aforementioned airflow challenge has led to odd bulb shapes, styles, and fin shows. Ask if the store has a no-questions-asked return policy.
