Hi All, I got my replication running last night. I used the same parts as Imhotep's setup. I found reasonable brightness on my single 125 watt equivelent bulb. The only issue I had was that my relay started to heat up after about 1 minute of run time. It got to the point where I could no longer hold it between my fingers because it was to hot. I double checked my circuit and do have everything hooked up correctly. My amp draw is around 3.5 amps from the primary batt. That is probably why the relay is heating up. I have several pots of various ohm ratings that I'm going to try on the relay and befor the relay to see if I can make a difference in this heating up problem as well as brightness of the bulb. I will also try another bulb in series for I have two of the same bulbs ready. Harbor Freight has a great deal on a 45 watt solar system until August 11th. for $189.99, regular price I think was $245 It has three panels and a charge controller.
Of course they didn't have any in stock but I got a rain check to hold my price until the units come in. I would like to use solar to run this lighting system and it will work great once we get this amp draw down to under a 1amp draw. This is exciting technology. Imagine lighting your whole house for penny's of electrical cost that you create yourself. Stephen
