That Lifespan Is Rated At 25

If you're looking to replace a 100W mild bulb, you'll find a number of LED choices at prices that are not almost as unreasonable as they had been just a year or two in the past. The current crop, including the Philips 100W Equivalent LED, hovers right around the $20 price level. Initially priced at $25, Philips' LED has since been marked down a number of bucks to $22, which remains to be barely more expensive than what you may see from opponents like GE and Cree. Philips justifies that by claiming an extra 80 lumens' worth of brightness over those two, together with superior dimming capabilities. However, our assessments didn't reveal any noticeable difference in either brightness or dimmability. That, along with the truth that Philips offers half the guarantee that you will 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 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, something that will get especially necessary when LEDs begin placing out this much gentle. Even with the emphasis on thermal administration, the bulb gets hot to the contact after just a couple of minutes of use, EcoLight solar bulbs which isn't unusual for a 100W replacement LED. As such, Philips recommends not using it in an enclosed fixture -- in the event you do, you may 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 energy-efficient bulbs a mean of three hours per day. Philips warrants the bulb for the first 5 of these years, reduce energy consumption while GE and Cree both provide ten-12 months warranties. 25,000 hours is the longevity benchmark for Power Star certification -- the Philips 100W Equivalent earned certification over the summer, as did the GE LED I tested. Cree's bulb isn't certified but, nevertheless it meets the standards -- Cree's crew tells me they expect it to be certified within the near future.



Philips claims a gentle 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 number, but not as spectacular as GE and Utilitech, EcoLight bulbs which both manage to put out 100 lumens per watt. These 1680 lumens are a slight step up from what you'll get with GE, Cree, or any of the other energy-efficient bulbs we examined. With brightness being considered one of the first things you want from your home lighting, that quantity would appear to present Philips an edge, albeit a minor EcoLight one. Nevertheless, EcoLight solar bulbs the engineers at Vitality Star test bulbs out for energy-efficient bulbs themselves, posting the total specs for every LED they certify on-line. On Philips' itemizing, Power Star rates the bulb at 1,620 lumens -- not 1,680. While an additional eighty lumens is simply barely enough to make a noticeable difference, an additional 20 lumens is essentially insignificant. We wished to know which number had it right.



From a easy eye check, energy-efficient bulbs the sunshine put out from the Philips 100W Equivalent LED doesn't differ a lot from its nearest opponents, the Cree and GE 100W replacements. Facet by aspect, the three have almost similar glows, all of them boasting equally heat tones. That is not stunning, given that each one three are rated with the identical 2,seven-hundred K coloration temperature. When tested, each erred low, on the yellowy aspect. Remember, though, that Philips claims to put out 1,680 lumens to Cree and energy-efficient bulbs GE's 1,600. That is a reasonably minuscule distinction, but it is one which needs to be noticeable if you're looking intently for it. The issue is that I couldn't discover it. Testing bulb brightness will get a bit difficult. In addition to measuring colour temperature and colour rendering scores, our spectrometer can take luminosity readings from a given gentle -- however those readings are simply skewed by issues like viewing angle and distance. To get numbers you'll be able to depend on, you need something known as an integrating sphere.
