I just wanted to say that I was burning two 15 watt CFL's in a lamp post but replaced them with three 2.8 watt LED bulbs.
The LED's draw about 1.5a from my batteries at night vs around 5a with the CFL and are just as bright.
LED
9w / .56pf / .9 = 17.85w / 12v = 1.5a
CFL
32w / .59pf / .9 = 60.26w / 12v = 5a
(90% efficient inverter)
I could only burn the CFL's every other night with my limited setup to prevent undercharging my batteries.
Now, except for days of bad weather I mainly need to watch over-charging.
Someday I'll get me one of those fancy charge controllers.
