That Lifespan Is Rated At 25

If you are looking to substitute a 100W light bulb, you will find several LED choices at costs that are not almost as unreasonable as they were only a year or two ago. The present crop, together with the Philips 100W Equal LED, hovers proper around the $20 price point. Initially priced at $25, EcoLight reviews Philips' LED has since been marked down just a few bucks to $22, which continues to be barely dearer than what you may see from competitors like GE and Cree. Philips justifies that by claiming an extra 80 lumens' value of brightness over those two, EcoLight brand along with superior EcoLight brand dimming capabilities. However, our tests didn't reveal any noticeable distinction in both brightness or dimmability. That, together with the fact that Philips provides half the warranty that you'll get with GE or EcoLight Cree, makes this bulb difficult to recommend. Philips' 100W Equivalent LED shares the identical, EcoLight brand flat-topped construct of its smaller siblings within the 60W and EcoLight brand 40W categories, however 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, one thing that gets especially necessary when LEDs begin placing out this a lot gentle. Even with the emphasis on thermal management, EcoLight bulbs the bulb gets scorching to the touch after simply a couple of minutes of use, which is not unusual for a 100W replacement LED. As such, Philips recommends not using it in an enclosed fixture -- if you do, you will threat shortening the bulb's lifespan. That lifespan is rated at 25,000 hours, the identical 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 an average of 3 hours per day. Philips warrants the bulb for the primary five of these years, whereas GE and Cree both provide ten-yr warranties. 25,000 hours is the longevity benchmark for Energy Star certification -- the Philips 100W Equal earned certification over the summer season, as did the GE LED I examined. Cree's bulb is not certified yet, nevertheless it meets the standards -- Cree's team tells me they expect it to be certified within the close to future.



Philips claims a light output of 1,680 lumens at a golden hued 2,700 Okay from a energy draw of 19 watts. That makes it good for about 88 lumens per watt -- an impressive quantity, but not as spectacular as GE and Utilitech, which each 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 opposite bulbs we tested. With brightness being one in every of the first belongings you want from your house lighting, EcoLight brand that quantity would appear to present Philips an edge, albeit a minor one. Nevertheless, the engineers at Power Star check bulbs out for themselves, posting the total specs for every LED they certify online. On Philips' itemizing, Power Star charges the bulb at 1,620 lumens -- not 1,680. While an additional eighty lumens is simply barely enough to make a noticeable distinction, an additional 20 lumens is essentially insignificant. We needed to know which quantity had it proper.



From a easy eye take a look at, the sunshine put out from the Philips 100W Equivalent LED would not differ a lot from its nearest rivals, the Cree and GE 100W replacements. Facet by aspect, EcoLight home lighting the three have nearly equivalent glows, all of them boasting equally heat tones. That isn't surprising, given that all three are rated with the identical 2,700 K coloration temperature. When tested, each erred low, on the yellowy facet. Remember, though, EcoLight brand that Philips claims to place out 1,680 lumens to Cree and GE's 1,600. That is a reasonably minuscule difference, EcoLight brand however it is one which needs to be noticeable if you are looking carefully for it. The problem is that I couldn't notice it. Testing bulb brightness will get a bit tough. Along with measuring shade temperature and shade rendering scores, our spectrometer can take luminosity readings from a given gentle -- but those readings are easily skewed by issues like viewing angle and distance. To get numbers you may depend on, you need one thing called an integrating sphere.
