[Originally posted at Jetson Green. This is pretty impressive looking at least at first glance. I haven't seen a distribution photometric, but it's supposed to be a pretty broad angle of lighting, unlike some of the early LED bulbs. This is only a 20-watt equivalent, but it won't be long before there's a 60-watt equivalent being sold in 4-packs at the big box.]
What can you do if you’d like to use an energy efficient light bulb, but you think that they look funky? How about a LED bulb that looks and functions almost exactly like an incandescent filament bulb?
Panasonic has introduced a clear bulb with a standard base that looks almost identical to an incandescent. It has a warm 2700K light color, similar to an incandescent. It has the lifespan (40,000+ hours) you would expect from an LED. And it only uses 4.4 watts of power, but produces 210 lumens, the light equivalent to a 20-watt incandescent.
This bulb also has a color rendering index (CRI) of 80, which is similar to other LEDs and good CFL bulbs. And, as with other LED bulbs, the bulb contains no mercury.
