Two spot or floodlights like used for outdoors. ONes with heavy glass, not light indoor kind. One on each end pointing to middle. I have box and outdoor adjustable sockets on them, but rarely ever move them. One on left is in back corner, one on right is in front corner, so I can open door and still get parts thru bigger part of the door. BUT, if on and hot, doesn't take much of a bump to make them knockout the filaments and have to change. You get better at not hitting them after a few hits and outages, ha! Try diff brands of bulbs, some last longer than others. You can add a switch on outside of box for them or as I do, just plug in when using cabinet, no switch. I use TP parts, good stuff and quick ship. A little more money, but good service. I also use that expensive Hardened metal tip, lasts a real long time. The other metal ones are better than ceramic, but even those can wear in short time. Have even had the outer section of the gun that holds the tip wear thru areas inside it's body and need replacement. Everything on a blaster wears out fairly fast.
