Should be fine for some softies. It's hard for me to recommend something like that as I've not tried it. They do get hot. Running them at 1000mA, they can actually damage themselves in minutes without proper cooling.
As an update, I have phase 1 done on this new venture. The enclosure is built and painted and has been mounted on top of my canopy. I'm amazed at how bright it still looks. I can't wait for the optics to show up. Could be a week and a half, still.
