Here's an idea, just buy a power inverter from an auto store and it will convert your 12V source to 120V AC power. Then you can use whatever lighting you want, rather than dinking around with LED lights. LED's aren't very good for growing, they're quite uneconomical to get started with.

Just make sure that you get a power inverter that is rated for the wattage you intend to use.
mountainman Reviewed by mountainman on . 12-volt lights ??? this is an odd question, I'm sure ... whats the feasibility for growing indoors under 12-volt lights ... possibly car headlights ?? ... this is for a stealth grow with no available AC electricity ... I'm curious which sort of 12-volt light would be best ... conventional, halogen, etc. ... ??? :stoned: Rating: 5
