If you want to install some 12V LED strips powered by 120V AC home wiring you need one of these. I needed to upgrade these two drivers from 12W to 24W after adding more LEDs to my runs. Make: DALS Model: BT12DIM-IC Bought originally from EECOL here in town. Worked perfectly before they were replaced. Both have all their bits and connectors. I just put them into the boxes from the 24W replacements. $20 for both is a steal. Just want to avoid going straight to e-recycling. Cash only. Come and get 'em.
