Yup they work great. I bought one a couple years back and have been using for every board since. I actually took mine apart and used the parts to build more of a curing oven setup. The one i purchased was a canopy (top half only) which provided more than enough bulbs to get the job done.
i build hws only so theres a freaking lot of work going into each board before getting glassed. i just wanna go safe and dont mess anything up… it kind of gives me a good feeling not to be in a hurry.
