uppo 0 Posted January 29, 2016 Hi all. I'm installing additional IR lights for my system and wanting to know how many amps I need. Budgets is tight so I don't really want to spend more then I have too. iv used replacement LED boards that you use in dome style cameras . Each have 48 LEDs. Iv constructed two housing an each housing contains 5 of these LEDs boards. So 10 LED board in total. I plan on powering these lights from there own power supply . How many amps do I need before I start losing power to the lights? Iv got a 12v / 3amp switching power supply Iv been testing various lighting ideas with. Would this be enough to power my lights? There not much info from the suppliers about how many amps these boards need. Share this post Link to post Share on other sites
