ok, i was just currious about it,,,<p>i use it with a flourscent light,, 2-3 second delay for the inverter to fire up and 1 secone for light to fire up,,, kind of a drawback,, and i do not want to leave the inverter on all the time, since this is a solar set up,, need to conserve power as much as po...

ok, but if possible i whould like to have one with out a relay..maybe a trasnsistor or scr if possible...the load is less 1 amp.. thanx

anyone have a scematic to share ? i am using low voltage lights ( LED's ) running off of batteries and only need them on at night. i can only find high voltage foto cells ( 120v. ) i need a solid state low power consumption foto cell that will work off of 12v.<p>if anyone can reply with a schematic ...
