Well, they're full of **** on the specs if nothing else. If the first one is really 17 watts, and it uses 3 AAA cells, which is 4.5 volts, that means it's drawing 17/4.5 = 3.7 amps from the AAA cells.

First off, AAA cells won't even deliver ONE amp. But even if they did, that would give you about a 10 minute runtime.

They may be trying to imply that it puts out as much light as a 17 watt incandescent lamp. But they'd need at least a 2 or 3 watt LED to do that, and even that is problematic with AAA cells.

Same analysis holds for the other one.

If you do decide to get these, be sure to let us know how it works out. I suspect that you'll go down the road a bunch of us did (including myself) - I spent $20 to $35 each on about 5 lights before finally giving up and spending the money to get a real light. I blew more money on crappy lights in the end than if I'd just bought a good light to start with.

I think a lot of us have a shoebox full of crappy useless $20 lights that we'd be happy to mail to you.
