New Crop of LED Filament Bulbs Look Almost Exactly Like Incandescents

Posted by timothy on from the not-according-to-everyone dept.

An anonymous reader writes A recent article posted on a green building site gives a detailed analysis of a creative new kind of LED bulb that has been popping up Europe and Asia over the last year. They look almost exactly like Tungsten filament bulbs, require no heat sink, and offer extremely high efficiencies in the 100-120 lm/W range. The article describes their construction, compares them to conventional LED bulbs, and describes the result of a report by the Swedish Energey Agency that analyzed the performance of several brands of these these bulbs on the European market. Particularly interesting are links to teardown videos.

    How can anyone think this will work?

      Ah but you can get WiFi enabled ones, that can adjust color/light levels in conjunction with whatever TV show is on.

      You forgot to point out that it isn't from Apple... Obviously, all other bulbs will become obsolete when the iBulb comes out...

      I wouldn't call them obsolete, but either way they won't fit in the same socket.

  2. I'll never give up incandescents. EVER. by Anonymous Coward · · Score: 4, Funny

    I heat my house with incandescent bulbs. Until LED's can do the same thing, I will never switch. What kind of an idiot would switch to a less efficient method of lighting AND heating their house?

      LEDs could do the same thing. 300 watts of incandescent and 300 watts of LED will do the same heating.

      You'll just have a lot more light with the latter.

  3. I still use whale oil by jfdavis668 · · Score: 4, Funny

    Forget those new fangled light bulbs, I still burn whale oil to light my house. A little pricey to import from Japan, but well worth the effort in the end.
