These look interesting. Anyone want to give some opinions on them. Maybe pair them up with a fasttech driver for a cheap veg light?

I tried this one, very similar to the first one you linked. It is nice because the light is so spread out, but the aluminum base is warped quite a lot so it took me a lot of work to sand it flat. It didn't take long before I burned it out during testing, I put 900mA of current through it and poof.

In terms out output, for $7.12 you could get a Vero13 and for $12.61 you could get a Vero18 and they come perfectly flat and will not burn out, even at 2X max current (I torture tested a Vero 10 and it did not care.)
