New Crop of LED Filament Bulbs Look Almost Exactly Like Incandescents
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.
