That Lifespan is Rated at 25 > 자유게시판

If you are trying to change a 100W gentle bulb, you may find several LED options at costs that aren't almost as unreasonable as they had been just a year or two in the past. The current crop, EcoLight bulbs together with the Philips 100W Equivalent LED, hovers proper across the $20 worth point. Initially priced at $25, Philips' LED has since been marked down just a few bucks to $22, which continues to be barely dearer than what you'll see from competitors like GE and Cree. Philips justifies that by claiming an additional eighty lumens' price of brightness over those two, together with superior dimming capabilities. Nevertheless, our tests did not reveal any noticeable distinction in both brightness or dimmability. That, along with the fact that Philips offers half the warranty that you will get with GE or Cree, makes this bulb tough to suggest. Philips' 100W Equivalent LED shares the identical, flat-topped construct of its smaller siblings in the 60W and 40W classes, however sets itself apart with a unique design that splits the bulb into three sections separated by deep channels.

This helps keep the heat buildup at bay, one thing that will get especially necessary when LEDs begin placing out this a lot light. Even with the emphasis on thermal administration, the bulb will get scorching to the touch after just a few minutes of use, which isn't unusual for a 100W substitute LED. As such, EcoLight dimmable Philips recommends not utilizing it in an enclosed fixture -- if you do, you may risk shortening the bulb's lifespan. That lifespan is rated at 25,000 hours, the same as the opposite 100W substitute LEDs I examined, with the exception of Utilitech. That lifespan comes out to 22.8 years if the bulb is used for a median of three hours per day. Philips warrants the bulb for the primary five of those years, energy-efficient bulbs whereas GE and Cree both offer ten-year warranties. 25,000 hours is the longevity benchmark for Vitality Star certification -- the Philips 100W Equivalent earned certification over the summer season, as did the GE LED I examined. Cree's bulb isn't certified yet, but it meets the criteria -- Cree's staff tells me they count on it to be certified within the close to future.

Philips claims a light output of 1,680 lumens at a golden hued 2,700 Ok from a power draw of 19 watts. That makes it good for EcoLight about 88 lumens per watt -- a formidable number, however not as spectacular as GE and Utilitech, which both manage to place out 100 lumens per watt. These 1680 lumens are a slight step up from what you will get with GE, Cree, or any of the other EcoLight bulbs we examined. With brightness being certainly one of the first stuff you want from your home lighting, that quantity would seem to provide Philips an edge, albeit a minor one. Nevertheless, the engineers at Energy Star take a look at bulbs out for themselves, posting the total specs for each LED they certify online. On Philips' itemizing, Power Star charges the bulb at 1,620 lumens -- not 1,680. While an additional 80 lumens is simply barely sufficient to make a noticeable difference, an additional 20 lumens is basically insignificant. We wished to know which quantity had it right.

From a simple eye check, the light put out from the Philips 100W Equivalent LED does not differ much from its nearest opponents, the Cree and GE 100W replacements. Facet by facet, the three have nearly identical glows, EcoLight solutions all of them boasting similarly heat tones. That is not surprising, given that all three are rated with the same 2,seven-hundred Okay colour temperature. When examined, each one erred low, on the yellowy side. Remember, although, that Philips claims to put out 1,680 lumens to Cree and GE's 1,600. That's a reasonably minuscule distinction, but it's one which must be noticeable if you're wanting intently for EcoLight it. The issue is that I could not notice it. Testing bulb brightness will get a bit difficult. In addition to measuring colour temperature and shade rendering scores, our spectrometer can take luminosity readings from a given gentle -- but these readings are simply skewed by things like viewing angle and distance. To get numbers you possibly can depend on, you want one thing called an integrating sphere.
