No, they wont. If you don't know about something, please don't post incorrect info about it. How do they use "half" the energy? If you see I posted the Lumen's per Watt of common lights, LED's do not save power per Lumen of light they emit. Also, we don't even know the light output of the LED's he's talking about. So they are saving half of what??

If I'm a little aggressive against newbies posting wrong info, it's because of my time over at the Pirate4x4 board.
