Thank you for your reply.Of course it's possible. But to answer the question "HOW?" we'll need to know what power source you want to use. We could tell you how to do it with a 45 volt battery - but you might not just happen to have one handy. So we can't answer the how until we know more about what you are working with. Including more information than 3W LED's. Are these running at 110VAC? Are they running on 5VDC? 12VDC? Exactly what voltage? What power source? We can help you get there. I just don't want to do it FOR you. I'll help if I can. If I can't - I'll be sure to make that clear. Won't give you bad information if I can help it.
I don't know...looks like the drivers needs about 4 volts of overhead so it might not produce the output voltage needed with a 48 volt input.You should be able to drive 120 3W LEDs from a 10A 48V supply by using 8 strings of 15.
Yes i figured thank you .Depends on which of the contradictory numbers you use. He originally asked about 30 LEDs. Then we find out he had 60 and was adding another 60. And the power supply is either 250W as he stated or 48V x 10A.
