I don’t understand what would make this bulb more desirable than the LED bulbs you can buy now for as little as $8.50 on Amazon. I realize that it costs a bit more for dimmable.
My guess is it is the promised lifetime, but unless they give you a guarantee for that 20 year period, I don’t know how you can count on it.
I’ve just started dabbling in LED bulbs. I’ve got one that looks a lot like a nice 60-watt incandescent, which works great as a standalone light in my TV room (light enough to move around, but doesn’t cast harsh light on the screen like the CFL). It’s 6 watts.
I’ve got one in my bathroom that is only 2 watts, and puts out a more “point source”. I pointed it at a mirror, and it is a fine light for almost everything you have to do in the bathroom. I have a CFL that is slightly unscrewed in the other light socket, so if you need extra light you just turn it a bit. At 2 watts, you can afford to leave the thing on all day. However, this isn’t really the right light for a bathroom, my plan is to mount it on a directional light off a wall that I can use as a reading light, because with it’s directional feature it’s like a 100-watt bulb if you point it where you need it. It is surprisingly bright for 2 watts, and it only cost me $10 bucks and it’s dimmable.
But I’m seeing how long it will last. That is what my test is now.
Still, if I had a guaranteed 20-year cycle, I would pay $60 for LED bulbs for all of my enclosed hard-to-reach fixtures.
The plan is to be able to run most of the lights in my house on a UPS unit. I’m still working on a UPS unit big enough to run my FIOS box and TV for 8 hours. :-)
I am really going to buy a propane generator (I was going to use gas, but with propane I am truly off-grid for months if things go bad — otherwise I’d use natural gas because I’ve never lost gas feed before). I want to be ready when the EMP pulse hits.
Have you seen that you can just update a standard UPS with a bigger battery (or battery stack)?
