LED bulb review

To show you how lame I am, I have no idea what the "wattage" rating is for this monstrous thing. Or the price. Or much of anything, except that this is the smaller of two sizes, it's not quite bright enough to read by, and it seems to require about as much juice as a CFL that is. At least that's what my inverter tells me.

The bigger size is physically much larger, making it impossible to fit in a standard light fixture. It needs to be bigger, since it just contains a whole bunch more LEDs. If this is the best the industry can do, CFLs are in no danger.

Ironically, this one gives off a blue-ish light that's a bit jarring to eyes grown accustomed to CFLs. And that's coming from a guy who spent some time bitching about the quality of CFL light.

On two different occasions I bought a LED bulb advertised to last 100,000 hours. Both failed within a week. The industry is failing.

You got the wrong kind, it looks like. You need Cree LEDs. But they're not cheap.

I have four LED light bulbs. Two are Geobulbs, which I bought a while back, for lots of money. The two newest ones I got recently. A 60-watt equivalent that draws 7 watts from the wall for $18, and a 100-watt equivalent that draws 12 watts for $25. From Amazon. All four bulbs look just like regular Edison light bulbs, but they're quite a bit heavier. The two new ones are plastic, and advertised with a video showing one of them surviving a drop from eight feet. I haven't tried to reproduce that, but I can tell that they're tough.

The 100-watt equivalent is plenty bright enough for a desk lamp. The others are serving well in locations that are kept on a lot.

The LED chips may well last 100,000 hours. The problem is that they require a driver (which is roughly equivalent to a transformer) which is in all likelyhood _not_ guaranteed for 100,000 hours.

No driver, no light whether the chip's good or not.
