New floundering setup

[peiserma]

Stinky_Hooker gave a link to where he bought them, its at the bottom of the 3rd post. The website says 12V, 27W, so that's around 2.25A (for each spotlight, they come 6 to a set. Doesn't look like you can buy just one). If you're running all six at once, that's 13.5A or 108 Ah (Amp-Hours) over 8 hours...

Be aware that the Ah rating applies either for a specific discharge rate, over a specific time. If you exceed the discharge rate, then you'll get less Ah out of the battery. So YMMV depending on the battery.
