The skinny Philips SlimStyle is flat, but well-roundedWe see value with this low cost, high efficiency LED.
Hey, I'm CNet's [UNKNOWN]. And today we've got a review of the Phillips SlimStyle LED. Now dont' be fooled. This is not a pint sized ping pong paddle, this is a lightbulb. It's got a unique design that spreads the diodes out along the perimeter of this, kind of, horseshoe shaped body. And that makes for better heat dispersion and means that the bulb doesn't have to rely on heavy aluminium heat sinks. Because of that, this is a very lightweight LED. It weighs in at just 2.2 ounces and that's less than half of what you'll see from a lot of other LED's including Phillips's own standard 60 watt equivalent LED. The [UNKNOWN] style puts out 800 lumens of light from a power draw of 10.5 watts. And that's very good. That gives it an efficiency of about 76 lumens per watt. Not quite as good as what you get from the [UNKNOWN] LED but still, very nice. Another thing I like about it is that it doesn't seem to do well with heat. We tested over time to see how heat effects the power output of these bulbs. All of them are going to drop off a little bit in the first 30 minutes after you turn them off as the heat cranks up. It's gonna effect that power output slightly, not that noticeable, it doesn't make it that much dimmer but it still happens. With the Phillips Silmstyle though it happens a lot less. If you look at this graph, the purple line on top there, that's the Phillips SlimStyle. You can see the power and the brightness dropping off a couple percentage points after you turn it on. All the bulbs do that, but it flatlines right about 93% and that's higher than any other bulb we tested. That means that the heat is affecting it a lot less. Now the translation for practice purposes is that if you wanna use this bulb in an inclosed fixture, you're probably gonna have good results compared with you might get from other bulbs where that heat build up inside that inclosed fixture would effect performance over time, maybe shorten the life span a bit. You won't wanna use it with a dimmer switch though, there are better bulbs for that purpose that won't buzz or flicker quite as much as the slim style will. You can pick up the Phillipson style 60 watt equivalent for about nine dollars. It's a pretty good deal. So, if you like this design or don't mind this design maybe, I say check it out.
