GE Figures Out How To Squeeze 100W Of Light From A 27W LED Bulb

One drawback of LED lighting is that as the bulb's output wattage grows, so too does the chip cooling system. But GE's new Energy Smart bulb's ingenious cooling design packs a 100W of power at a quarter the energy requirements of a standard A19 incandescent.

To cram the necessary parts into the A19 shape, GE partnered with Nuventix to replace the conventional cooling fans with something they call a synthetic jet — essentially an oscillating membrane that helps dissipate the heat. In addition, the Energy Smart bulb emits at the 3000K colour temperature and is rated at a 25,000-hour service life.

"Our innovation team has tackled a previously insurmountable technical challenge: cooling a 100-watt A-19 shaped replacement LED bulb without making it physically bigger," said Steve Briggs, general manager of LED systems, GE Lighting in a press release. "Each subsystem such as optics, electronics and thermals needed to be designed for miniaturisation and cooperative performance. We explored the limits of what's possible and pushed far beyond industry expectations and competitors' thinking and product offerings."

GE engineers plan to further develop this technology to exceed the new 100W limit. For now, the Energy Smarts will hit store shelves by June of next year but no price has been set yet. You can expect them to be pricey, though. [GE Lighting]


    Sounds good. Hopefully they have a 2700k temp version though, I prefer the warmer temperature bulbs. Also I dunno about other people, but my bulbs are usually less than 100watts, usually around 60watts

    Buuuuut standard CFC bulbs rated at 100W are common already at 20W so am I missing something big here?
    I though LEDs gave more light at less power than CFCs, this sort of seems like that's not true...? They also don't need huge bulky, expensive cooling systems.

      correct me if I'm wrong but I think you mean CFL . In my experience, 100w CFL's are no where near as bright as incandescence's.

        The thing about CFLs is that they take time to reach their full brightness - in the order of about 15 minutes. This is one of the reasons incandescents should NOT be discontinued: as much as I like CFLs cupboards, bathrooms, basements, laundries and other areas where you'll only have the light on for short periods will actually be better off with an incandescent than a CFL.

          Disagree, sorry, but if they didn't ban incandescent lights people would still have them all over their houses not just the quick use areas. Most modern CFL's come close to full brightness a lot quicker these days. With the possible exception of the brighter models, which still take a bit longer.

    The headline is impossible: it should be changed to something like: "GE figures out how to get the light of a 100W incandescent from a 27W LED bulb".

    100W of light is 100W, the absolute minimum amount of power required to produce it from a perfectly efficient light source (more efficient than an LED ever will be) would be 100W.

      the problem here is you presume that giz is a source of intelligent and accurate news.

      in reality its more like "ZOMG NEW GADGET ZOMG ZOMG, SHINEY THING!!!"

    I have a requirement for instant on light (from my wife :-) - compact flouros are often pants there as discussed. I use generally use OSRAM LED bulbs now - max rating that is "affordable" is 12w white/warm white (~700/600lm) which are equivalent to a 60w/50w 180 degree reflector incandescent (or roughly a 40w halogen) - perfect for ceiling lights. I have one fitting with a "Y" adapter that allows 2 bulb in one socket (its a big fitting!) - so the same as a 120w bulb in 24w. The "commercial" OSRAM ones that I can get go up to 48w POWER USE (!) in standard commercial fittings, but are more than proportionally expensive (my "Y" setup is about 2/3 the price of a 24w LED and gives MORE light that is distributed better to boot). The large watt ones are not silent past a certain number of watts and they are also LESS efficient per watt, unlike incandescent where the opposite is true (more watts = more efficient for incandescent ). For non directional lights like table and standard lamps I use 4-6w "omni" array (multi-module) LEDs from deal extreme - they are cheap and MUCH more efficient than 15-40w incandescent or small CFL.

    In terms of CFL vs LED, well they are both actually florescent - one uses gaseous quantum electron effects to make UV to a phosphor and the other uses solid state quantum effects to make UV to a phosphor, the theoretical max efficiency is similar and the practical efficiency is converging as is the cost. I like the instant on of LED, the higher life time and the lack of mercury + even now the cost per usable hour is LOWER for LED and for sub 600lumen bulbs they are more efficient than CFL - for really small bulbs like torches there is NO contest - LEDs rule, and have for 5 years at least.
