Not good for lamps.
on May 9, 2014
I'm surprised at all the positive reviews about this bulb. There's an obvious downside to this compared to a traditional incandescent or fluorescent bulb: It emits it's light from only half it's hemisphere! If you put it in a lamp, the top half of the shade is illuminated, the bottom half is not. Not only does it affect the aesthetic of your lampshade, it diminishes it's usefulness if you use it as a reading lamp. Most of the light is thrown up, not down.
I'm an architectural photographer. Lights, lamps, and lampshades are part of my everyday existence. This is a glaring (pardon the pun) defect of this (and many other type) of LED bulb.
What's good about it? I can't speak for it's longevity...I just purchased one to try it our in my living room (and it will be replaced). It appears well made and robust. It does emit a warm light that is comparable in temperature to traditional incandescent bulbs. It doesn't get hot. It does turn on immediately (unlike some other LED bulbs I've tried that have a delay). I trust that the lamp draws only 12W as advertised. Other than that, I have to give this a "D" grade simply because it doesn't emit light in a nice sphere like you'd expect a bulb to.
