6 leds about 35 bucks
1000ma dimmable buckpuck with pot 20 bucks
24v power supply 15 bucks
heatsink-be creative 0-25 bucks
screws+wires+other stuff not included
the power supply should have a + side and a - side, connect accordingly to the driver which will have marked cable leads
driver will have a + and minus side to the leds
wire all the leds in series and the end
you will have no control over the color with this setup since you will only be able to dim all of them at the same time
if you got two drivers and hooked each driver up to its own color you could have blues going half power and whites going full or any combo you want, you could also get away with using a power supply you might find around the house, like an old laptop cord. you want about 4 volts per led, but a little less is okay and a driver takes 2v i beleive
