Semiconductor devices have never been cheaper!  I picked up a 5W, 650 lumens LED for single-digit dollars, along with a rechargable 3.6V NiMH battery pack and 6 solar cells for good measure.  I think it’s going to take a lot more solar cells to be worth it but hey, as long as they are no bigger than the batteries it will be fine…

Now how likely do you think it is that I will burn out that LED?  Stay tuned…
