Used these to aid in the bending of acrylic and it worked great. However, they pull a lot of power and need to be on a dedicated circuit of at least 30 amps if you use all three at the same time.
Worked very well with us 2 had come in broken an we were having trouble sending it back ,so they sent a replacement right away to us an didnt have to send the broken ones back which was nice of them to do
These work great! They definitely pop a 15 amp breaker and one out of six bulbs is dead. Other than those two, sure, they're cheap and flimsy but I really needed just the bulbs and something to hold them for a powdercoating oven project and they did just that.
Big power, dry paint really fast and produce a lot of heat, just you need to use a dedicated outlet for the lights if not the breaker trips, but other than that excellent for the cold weather!!!
