[ppreceipt]

just buy some premade lights.

you are probably better off just buying some premade solar lights

two of them have bad reviews. The other two have good reviews.

You can get two lights for $50. If you built it yourself I doubt you could do it much cheaper.

While I'm not a big fan of their solar products, you may want to look into Goal Zero's led lighting. Their "light a life" and "estrella" lights both run at about 3 watts dc. Typically a bit of a blue color temperature. I cut off their custom connectors and made my own.

The Luna led light runs from usb, so that's handy.

You could even forego solar altogether - I really like the RayoVac Sportsman Xtreme SE3DLN led lantern if you don't mind using 3 D-cell batteries. Pretty good reviews from the guys at CandlePower forums, although the battery installation / twist at the bottom is a little funky if you don't line things up just right. It's my favorite led lantern since it is small, bright, and configurable. Of course my D-cells are rechargeable by solar externally, but then I'm kind of nutso....

LED's here I come. If that. Sounds like you need a couple grand just for lighting.

So, I'm looking at LED lights? That friggin little light bulb is going to drain the damn battery in 12 hours?

Your battery if you burn 8 of those lights will be dead and destroyed in 1 hour and 15 minutes at most. Those lights use 1.8 amps x 8 = 14.4 amps. Your battery is 18 Amp Hours. So 18 AH / 14.4 amps = 1.25 hours or 1 hour and 15 minutes. In reality due to Peukert Law less than 1 hour.

You need to find a different light.

Ok, first post here, new to solar, just figuring this out. Need to make solar/battery purchase in a couple weeks.
I have a travel trailer I am wanting to keep lighted at night, thats about all for the electrical needs.

I am wanting to run up to 4-8 of these bulbs for at least a few hours a night: http://www.bulbs.com/espec.aspx?ID=10614

23/8.3 Watt, 12.8/14.0 Volt, 1.80/0.59 Amp Miniature S-8 Bulb

I am looking at this battery but I am getting the sinking feeling this battery would only run one bulb of this type for about 12 hours or so, is that correct? Then I am sunk.

12V/18AH/20Hr

This is not even including probably a 250 watt solar charger to keep this battery charged enough? I'm in a pretty sunny area.
