LED... Build or Buy?

[DSlater]

I would say there are some things you can cheap out on if you go DIY but I wouldn't cheap out on the actual LED's. The output per watt really varies.

I have both DIY and one of the dimmable Chinese 120w off ebay. Went and bought the best LED's I could find for the DIY and the light output and quality does not compare. Visually I would say I get twice the light output per watt from the DIY than the ebay fixture, better colour as well.
I cheaped out on fans and power supplies... have had trouble with both...
