Here's the best product of all if you want to save the planet. This 100 watt equivalent bulb only uses 10 watts! However, these LED lights are still expensive - this one is close to 100 bucks. Instead of putting up giant wind turbines everywhere that don't generate much power, I'd like to see our government fund the mass production of these bulbs. If we only needed one tenth the power we're now using, we'd really be getting somewhere.
