I picked up the 10 watt version at walmart; i was very surprised, especially compared to the 2.5 watt crane LED i have (the crane is very dim). this is in the category of ‘usable light bulbs’, it is very directional though. for me, the real question isnt ‘does it work’, because it seems to replace my 26 watt cfl’s ok (it is not as bright as the cfl), but i want to know if it’ll really put out the advertised life span.

If you need a reading light in a dark room and you plan to sit directly under the light, this may be useful to you. For most other applications, this has little value. The light is exceptionally dim. Perhaps not in comparison to the even-dimmer LED selection currently available, but certainly compared to other (vastly less expensive) lighting choices. The light is also focused in a very narrow spot. Unless you spend many hours sitting directly under a reading light every day, it will take you a very long time to recoup the cost of this bulb in energy savings (at current prices, anyway).

I purchased this bulb to replace a 50W Par20 halogen bulb mounted in a small double spotlight unit over my kitchen sink. In a side-to-side comparison with the halogen bulb, it provides the rough equivalent of a 40 watt halogen bulb, with a much whiter cast. It is about 3/4″ longer than the halogen bulb, which results in it being clearly visible at the end of the fixture (the halogen bulb is recessed enough to be hidden) so that it’s slightly more narrow beam is not restricted by the fixture as is the halogen bulb’s. The net result is a beam that is almost exactly as narrow as the original halogen bulb’s beam.
Finally, the exterior vents in the plastic casing provide a grip that makes this bulb exceptionally easy to insert and remove. I’ve had to use large forceps to remove some of the replacement halogen bulbs. As task lighting mounted 4 feet from my sink and kitchen counter, this is perfectly adequate. I’ve now ordered another for the other side of the fixture so I’ll have on overall savings of 86 watts.

Really glad I bought one, its bright white. Great for reading. Its very narrow flood lighting, its focus only in a narrow beam, wish it was a wider beam of light. Can’t use in enclosed fixture, but was able to remove my glass enclosed fixtures to use this LED bulb in. It ran fairly cool overall, its still warm to the touch but won’t burn your hands. Very heavy duty feel, I like the design of the swirl style heat sinks. Compared to my Philips LED bulbs, Philips has a slightly wider beam of light, but wasn’t as bright as this GE LED bulb. Prefer the GE over Philips. Haven’t tested any other LED bulbs. Its great by using so little energy to run, no waiting to warm up like fluorescents and not burning hot and energy consuming like incandescents. Highly recommend using this GE LED bulb, like most flood light LED bulbs best to use upside down, not sideways in dining room fixtures. Best to shine beam of light straight down, like directly onto your kitchen or bathroom sink. Suppose to last just over 10 years. GE has 3 LED’s inside, compared to Philips has 4 LED’s inside bulb.

I bought a few of these at Sam’s – they have a sweet colored light, don’t get too hot and put out enough light to light up (albeit a bit dimly) an entire room if relfected off a white ceiling. Recommend it.
