possble cheap alternative to ldd-l drivers?

been thinking about redoing a few fish room lights to get a bit more oomph so looking at cheap options. been leaning toards a basic bridgelux eb build. maybe 2x2ft ones over my 75s in my fish room. but looking to do them cheap. noticed these drivers when i was poking arround for cheap ac/dc drivers from [Ebay Link Removed] pretty good price point for 5 for under 10 bucks. anyone have any thoughts? they are 700mah 5-35V pwm compatable. basically a cheaper LDD-L driver

I wouldn't worry about the caps as long as you keep them well under their rated voltage. The problem there is at least one of them is a 35V cap which is also the rated voltage of the board. This would be OK if you use a 24V supply but I'm not sure you'd be able to run a 22V EB board since that's only 2V less than the supply, and you can't use a 36V supply.

The other issue I see is there are no mounting holes, so you'd have to find a way to mount them.

2nd gen Eb strips are 20v at the same amperage for the same amount of light. Pretty efficient lights at 180lm a watt.
