I agree that retail is not the same as DIY in that you get more and pay less for a DIY setup.

The retail LEDs are old technology. DIY with Cree, or even knockoff Cree LEDs, are waaaaay more powerful. One retail LED is not even in the same league as one Cree LED, so they cannot be compared as apples to apples.

True... Still comes back to price then.

This one is still $1899 for a 4ft fixture, with i'm guessing 48 LEDs:

yup and you can buy a kit with everything you need including optics, but no heat sink, for 48 LEDs for about 400 bucks.

Thanks for the links guys. I'm still preferring to do this total DIY as the fixture is for a Fluval Edge planted tank. I could have went with 2 MR16 base LED bulbs that would have plugged right into the Fluval edge fixture but I opted to go with 9 Cree XP-G 3W LEDs instead as I assumed I'd get better coverage and I enjoy most DIY projects. This is the 1s time I've ever had any problems with a DIY build and thanks to some of your comments, I'm assuming it was likely due to a build up of flux while soldering.

I haven't been able to find any wire thinner than 18 G locally so I still haven't resoldered the LED array. I did pick up a better soldering iron and a solder sucker to remove the excess solder from the previous job. I'll let everyone know if I do manage to get this build up and running.

I had seen the "solderless" LED connectors but opted to go without them due to mounting options. Very neat idea though.
