If you're looking to replace a 100W mild bulb, you may find a number of LED choices at prices that are not almost as unreasonable as they were only a year or two ago. The current crop, including the Philips 100W Equivalent LED, hovers proper around the $20 price point. Initially priced at $25, Philips' LED has since been marked down just a few bucks to $22, which continues to be slightly costlier than what you may see from competitors like GE and Cree. Philips justifies that by claiming an extra 80 lumens' value of brightness over these two, along with superior dimming capabilities. Nevertheless, our tests didn't reveal any noticeable difference in either brightness or dimmability. That, together with the truth that Philips gives half the warranty that you're going to get with GE or Cree, makes this bulb troublesome to recommend. Philips' 100W Equal LED shares the identical, flat-topped build of its smaller siblings in the 60W and 40W classes, but sets itself apart with a novel design that splits the bulb into three sections separated by deep channels.

This helps keep the heat buildup at bay, something that gets particularly essential when LEDs start placing out this much mild. Even with the emphasis on thermal administration, the bulb gets sizzling to the touch after simply a few minutes of use, which isn't unusual for a 100W replacement LED. As such, Philips recommends not utilizing it in an enclosed fixture -- for those who do, you may risk shortening the bulb's lifespan. That lifespan is rated at 25,000 hours, the same as the other 100W replacement LEDs I examined, with the exception of Utilitech. That lifespan comes out to 22.8 years if the bulb is used for a mean of three hours per day. Philips warrants the bulb for the primary 5 of those years, whereas GE and Cree both supply ten-year warranties. 25,000 hours is the longevity benchmark for Energy Star certification -- the Philips 100W Equal earned certification over the summer, as did the GE LED I examined. Cree's bulb is not certified but, but it meets the factors -- Cree's group tells me they count on it to be certified within the near future.

Philips claims a light output of 1,680 lumens at a golden hued 2,seven-hundred K from a power draw of 19 watts. That makes it good for about 88 lumens per watt -- a powerful quantity, however not as spectacular as GE and Utilitech, which both manage to place out one hundred lumens per watt. These 1680 lumens are a slight step up from what you'll get with GE, Cree, or any of the opposite bulbs we tested. With brightness being one in all the first belongings you want from your private home lighting, that quantity would seem to offer Philips an edge, albeit a minor one. Nevertheless, the engineers at Energy Star take a look at bulbs out for themselves, posting the complete specs for every LED they certify online. On Philips' itemizing, Power Star charges the bulb at 1,620 lumens -- not 1,680. Whereas an additional eighty lumens is just barely enough to make a noticeable difference, an additional 20 lumens is essentially insignificant. We needed to know which quantity had it right.

From a easy eye test, EcoLight outdoor the light put out from the Philips 100W Equivalent LED doesn't differ a lot from its nearest opponents, the Cree and GE 100W replacements. Side by side, the three have practically similar glows, all of them boasting similarly heat tones. That isn't stunning, given that each one three are rated with the same 2,700 Okay colour temperature. When tested, each 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 fairly minuscule difference, but it is one that needs to be noticeable if you are wanting closely for it. The problem is that I could not discover it. Testing bulb brightness will get a bit tough. Along with measuring color temperature and EcoLight color rendering scores, EcoLight outdoor our spectrometer can take luminosity readings from a given mild -- however those readings are simply skewed by issues like viewing angle and distance. To get numbers you possibly can rely on, you need something called an integrating sphere.
