So if i run one 55w light and a 5-6Ah 12v batt i should get 1 hour run time, right?!?
The 55w MR16 bulbs that came with my Optronics were yellow and I ended up tossing them. Get a Phillips high efficiency 20w MR16 - 55w draws too much current. The one thing I found about batteries is they never last even close to your calculations.
I bought my first set of 2 optronics housings from J.C. Whitney for about $22 shipped. I got a deal on several more off ebay. The only ones on ebay now are a 5-pack currently at $26 shipped.
