If you are interested in these units, I can get these in the 10-20k. It is built with heatsink all in one unit like the canon led unit. I didn't import these in because I thought it wasn't a high demand for them.
It also come in the 5,10,20,80,100,200,300 watts. I don't mean to jack your thread, but just want to share some info. I still think you need to add actinic to the 14k 50w unit.
