The SlimStyle is a 60W-equivalent LED bulb that produces 800 lumens and operates at 10.5W (76 lumens-per-watt). In many ways it’s a standard consumer LED bulb: it’s rated for 25,000 hours of life, it’s dimmable, it has an omnidirectional light pattern, and it has a CRI (color accuracy) rating of 80. All this means that Energy Star certification isn’t just possible… it’s pending. But after a single glance at the SlimStyle you’ll know that it’s not just another LED bulb. In fact, the term “bulb” isn’t exactly appropriate…
When looked at straight on, the SlimStyle appears to be bulb-shaped, but that’s actually only true in 2D. When turned, it’s clear that the lamp is flat on both sides and has a ring running around its outside which serves as a light guide. The design is unlike anything else found in the LED market today but not only because of its unique aesthetics, it’s also missing a part found on every one of its competitors: a metal heatsink.
Basically, LEDs don’t like to get hot — the heat decreases lifetime and brightness (I’ve spent a lot of time explaining that) so a metal heatsink is used to disperse heat, moving it away from the sensitive LEDs. With the SlimStyle Philips was able to move to an all-plastic body and still keep the LEDs cool enough to promise a 25,000 hour lifetime. And, in doing so, the company was able to move to this cool new design. Best of all: not only does the flat design help conduct heat away from the LEDs, says Philips, it also helps cut down on costs.
