building an LED, transformer question, ??

My friend brought me a sebco 1109 'low voltage lighting transformer' rated for 250w that he found in a trash heap.

Can you build an LED light using this? it says it can be used for any low voltage lamp rated for 12 volts, not to exceed 60 watts per output. 250 for the whole thing.

The spec sheet says output is 12VAC x 21A. I'm sure you could make an LED driver that's built around this thing, but I would not expect it to be any cheaper (or easier to acquire) than something already built around the power coming straight from the outlet.

Cheers.

On second thought, you could build an array around this PSU quite easily, I would imagine. I'm not exactly sure how to at the moment, but I'm guessing it will require 250W worth of LED (probably more so you don't run them at max current), some LED's in series and some in parallel (in order to keep LED's that are in series at 12VDC, while having an overall power consumption of 250W), and a resistor in front of every "cluster" of LED's that are in series to protect them from overdraw. Sorry for my lame original response. Hope you get this and consider the cost benefits vs effort, and I also hope some one with real electrical experience can come in here and lay everything out for you better.

Good luck.

Hey thanks for delving into more detail there. i'll look into it more then. i don't mind some extra effort to even save 5 bucks lol.
