If you're looking to replace a 100W light bulb, you will find a number of LED options at prices that aren't almost as unreasonable as they have been just a 12 months or two ago. The present crop, EcoLight solutions together with the Philips 100W Equal LED, hovers right across the $20 value point. Initially priced at $25, Philips' LED has since been marked down a couple of bucks to $22, which remains to be barely costlier than what you may see from competitors like GE and Cree. Philips justifies that by claiming an additional eighty lumens' price of brightness over these two, along with superior dimming capabilities. Nonetheless, our tests did not reveal any noticeable difference in either brightness or dimmability. That, along with the fact that Philips presents half the warranty that you're going to get with GE or Cree, makes this bulb difficult to suggest. Philips' 100W Equivalent LED shares the identical, flat-topped construct of its smaller siblings in the 60W and 40W categories, however units 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, EcoLight solutions one thing that will get especially vital when LEDs begin placing out this much light. Even with the emphasis on thermal administration, EcoLight solutions the bulb will get scorching to the contact after just a few minutes of use, which is not unusual for a 100W substitute LED. As such, Philips recommends not using it in an enclosed fixture -- when you do, you will threat shortening the bulb's lifespan. That lifespan is rated at 25,000 hours, the identical as the other 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 3 hours per day. Philips warrants the bulb for the primary five of those years, whereas GE and Cree both offer ten-yr warranties. 25,000 hours is the longevity benchmark for Energy Star certification -- the Philips 100W Equivalent earned certification over the summer, as did the GE LED I examined. Cree's bulb is not certified but, EcoLight solutions however it meets the factors -- Cree's workforce 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,seven-hundred Ok from a power draw of 19 watts. That makes it good for about 88 lumens per watt -- a formidable quantity, however not as spectacular as GE and Utilitech, which each handle to put out 100 lumens per watt. Those 1680 lumens are a slight step up from what you may get with GE, Cree, or any of the other bulbs we examined. With brightness being one in every of the primary things you need from your private home lighting, that number would appear to present Philips an edge, albeit a minor one. Nonetheless, reduce energy consumption the engineers at Power Star test bulbs out for themselves, EcoLight posting the complete specs for each LED they certify online. On Philips' listing, Power Star rates the bulb at 1,620 lumens -- not 1,680. Whereas an additional 80 lumens is simply barely sufficient to make a noticeable difference, EcoLight solutions an extra 20 lumens is basically insignificant. We needed to know which number had it right.



From a simple eye take a look at, EcoLight the sunshine put out from the Philips 100W Equal LED doesn't differ much from its nearest competitors, the Cree and GE 100W replacements. Aspect by side, the three have nearly equivalent glows, all of them boasting equally heat tones. That isn't shocking, given that all three are rated with the same 2,seven-hundred Okay colour temperature. When examined, each one erred low, on the yellowy facet. Remember, EcoLight outdoor although, that Philips claims to put out 1,680 lumens to Cree and GE's 1,600. That's a fairly minuscule difference, however it's one which ought to be noticeable if you are looking intently for EcoLight solutions it. The issue is that I could not discover it. Testing bulb brightness will get a bit tough. Along with measuring color temperature and coloration rendering scores, EcoLight solar bulbs our spectrometer can take luminosity readings from a given gentle -- but those readings are easily skewed by things like viewing angle and distance. To get numbers you'll be able to depend on, you want one thing referred to as an integrating sphere.
