A short time ago a friend asked me about the 50 watt solar panel they sell at H.F. That's not much power and running it through an inverter would just be silly. So I started trying to come up with something useful enough to justify the purchase.
I found an LED that puts out 420 lumins and only uses 5 watts. (this LED is only 20 bucks)
This is just enough light for a nice bedside lamp , and at only 5watts you could run ten of them off a 50 watt solar panel.
That's about as much light as a 40 watt light bulb . If you had ten 40 watt bulbs in your house and you replaced them with these you'd save 350 watts (that's a lot of watts).
If you'd like to build a few just follow this instructable. And remember , stay safe , have fun , and every dollar you save doing something green is a dollar that can be put back into the economy some where else to help make it strong again.
Go Green for the Green !!!
