Demystifying LED Lightbulbs > 자유게시판

Maybe you’ve already performed the righteous factor and swapped out all your power-sucking incandescents and never-universally-useful CFLs for lengthy-lasting, mercury-free, vitality-saving LED bulbs. Extra possible, you’ve dropped in just a few right here and there, with blended results. LED bulbs can still be chilly, alien-wanting things with odd shapes, splayed fins, and dazzling value tags. However they keep getting higher-and EcoLight products cheaper. Should you haven’t already, now's the time to start making the change, and we’re going to clarify how and why. The primary LED bulbs I tried made my dwelling room seem like a hospital ward. How do I keep away from that stark white light? Newer models do a greater job of diffusing the tiny directional beams that LEDs generate. But even so, you might want to start out with decrease-lumen (that means less bright) bulbs. LED bulbs-which house electronic circuits and gentle-emitting diodes that act as semiconductors reasonably than filaments-now come in "color temperatures," together with heat tones that can mimic incandescent bulbs and flatter furnishings, reminiscent of varnished wood.

Curiously, cooler ones are often recommended for outdoors as a result of they convey out the inexperienced in foliage, says Seattle-based mostly lighting designer Christopher Thompson. There’s sufficient small print on the package to blind a lawyer. Search for the requisite Lighting Information label, EcoLight products which posts the Kelvin (Ok) rating: The nearer to the decrease end of 2700K, the warmer the sunshine (sure, that does sound backward). Bulbs are additionally rated for EcoLight products his or her means to render color accurately, utilizing what’s called the Colour Rendering Index (CRI). Incandescents, which do particularly nicely with warmer colours, score 100. It's possible you'll must test the manufacturer’s website 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 after i could change one 60-watt bulb with one other! Lumens are a greater way to match brightness. Watts measure how much electricity a bulb draws, not light output, which varies, since not all 60-watt incandescents are equally environment friendly.

Extra important, 60-watt-equivalent LED bulbs could seem brighter, EcoLight lighting since the sunshine is cooler. So if you’re shopping for a 60-watt equal, consider trying a 40-watt equal as a substitute. Its 450 lumens could also be shiny sufficient. I really like my recessed cans but can’t discover an LED flood that has a broad, heat gentle. Search for a reflector bulb, such because the BR30 type, with a slight bulge near the face of the bulb. Information on the package deal should say whether or not the bulb is a "spot" or EcoLight products a "flood," and might also include the angle of the sunshine beam. When you need a flood, search for an angle of greater than 50 levels or the acronym WFL, for vast flood. Alternate options for EcoLight bulbs recessed cans also include LED floor-mount panel fixtures, equivalent to ones made by Pixi Lighting. One other problem: The dimmer is no longer able to deliver the sunshine method down. Traditional dimmers are often unable to function LED bulbs: They could flicker or EcoLight fail to reply-a syndrome often known as "dead travel." In different phrases, don’t assume a bulb labeled dimmable will jibe with the dimmer you’ve bought.

Go to the bulb maker’s website to see which dimmers go along with which bulbs-or EcoLight products consult the Lutron LED Control Middle of Excellence, which runs a toll-free hotline for pissed off customers: 877-DIM-LED8. Smartphones might develop into the ultimate solution; Philips already makes bulbs whose color and brightness are managed by an app. Can I stick an LED bulb in any fixture? Pretty much. Simply match up your previous bulbs’ bases with LED variations, taking care to also compare lumens, or brightness levels (once more, a lower-lumen bulb may be extra pleasing). Some new bulbs are surprisingly good at mimicking the familiar Edison, and one firm, Switch, has introduced the first three-method LED bulb. To soften the beam and make it less direct, manufacturers set up a number of LEDs, reflectors, lenses, and diffusers throughout the bulbs. Some bulbs look slightly humorous till you turn them on or put them behind a shade or EcoLight products inside a glass globe. However be aware that some LED bulbs can't be used inside enclosed fixtures or capped recessed lights.

As Ray Johnston, a staff scientist at 3M, explains, LED bulbs have "heat sinks"-fins or one other way out for the heat generated when vitality passes by way of the semiconductors-which assist them use a lot less wattage and emit a lot less heat than incandescent bulbs do. But on the flip aspect, LEDs are extra sensitive to their surrounding temperature and want a good amount of airflow to work nicely. Overheating won’t make a bulb explode, but it'll shorten its life. As for chilly temperatures, unlike CFLs, LEDs do high-quality outdoors. How about replacements for unusual bulbs? Search for LED pin bulbs that may replace halogens, EcoLight small bulbs for candle-fashion fixtures, and specialised LED fixtures, corresponding to undercabinet strip lights from firms like Kichler and Häfele and battery-operated lights for drawers and closets from the likes of GE and EcoLight reviews IKEA. Take into account that the aforementioned airflow problem has led to odd bulb shapes, kinds, and fin displays. Ask if the shop has a no-questions-asked return policy.
