That Lifespan Is Rated At 25

If you are seeking to change a 100W gentle bulb, you'll find a number of LED choices at costs that aren't practically as unreasonable as they have been just a yr or two ago. The current crop, together with the Philips 100W Equivalent LED, hovers right across the $20 value point. Initially priced at $25, Philips' LED has since been marked down a number of bucks to $22, which is still barely more expensive than what you will see from opponents like GE and Cree. Philips justifies that by claiming an extra eighty lumens' value of brightness over these two, EcoLight together with superior dimming capabilities. However, our checks did not reveal any noticeable difference in both brightness or dimmability. That, along with the truth that Philips provides half the guarantee that you're going to get with GE or Cree, makes this bulb troublesome to advocate. Philips' 100W Equivalent LED shares the same, flat-topped build of its smaller siblings in the 60W and 40W categories, however units 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 will get especially vital when LEDs start putting out this much light. Even with the emphasis on thermal management, EcoLight the bulb gets hot to the contact after simply a couple of minutes of use, which is not unusual for a 100W substitute LED. As such, Philips recommends not using it in an enclosed fixture -- should you do, you may risk shortening the bulb's lifespan. That lifespan is rated at 25,000 hours, the identical as the other 100W alternative LEDs I tested, with the exception of Utilitech. That lifespan comes out to 22.Eight years if the bulb is used for a median of three hours per day. Philips warrants the bulb for EcoLight the primary five of these years, whereas GE and Cree each supply ten-yr warranties. 25,000 hours is the longevity benchmark for EcoLight Vitality Star certification -- the Philips 100W Equivalent earned certification over the summer season, as did the GE LED I tested. Cree's bulb isn't certified but, but it meets the factors -- Cree's crew 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 Okay from a power draw of 19 watts. That makes it good for about 88 lumens per watt -- a powerful number, but 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 tested. With brightness being one in all the first stuff you need from your home lighting, that quantity would seem to present Philips an edge, albeit a minor one. Nonetheless, the engineers at Power Star check bulbs out for EcoLight themselves, posting the complete specs for each LED they certify on-line. On Philips' listing, EcoLight Energy Star rates the bulb at 1,620 lumens -- not 1,680. While an additional eighty lumens is simply barely sufficient to make a noticeable distinction, an additional 20 lumens is basically insignificant. We needed to know which quantity had it proper.



From a easy eye test, the light put out from the Philips 100W Equivalent LED does not differ much from its nearest competitors, the Cree and GE 100W replacements. Aspect by side, the three have almost identical glows, all of them boasting similarly warm tones. That isn't surprising, given that each one three are rated with the same 2,seven-hundred Okay shade 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 is a fairly minuscule difference, but it is one which should be noticeable if you are looking intently for it. The issue is that I couldn't discover it. Testing bulb brightness gets a bit tricky. Along with measuring color temperature and coloration rendering scores, EcoLight our spectrometer can take luminosity readings from a given mild -- however these readings are easily skewed by things like viewing angle and distance. To get numbers you possibly can rely on, you need one thing referred to as an integrating sphere.
