LOL too funny ...
They are 250 watt quartz lights, and that what they look like when you "hit" them with power. cool effect for a $6.00 light. You can get them in all kinds of sizes but 250 works best for us guys.
I have a Light-O-Tower made with 8 of them and we can pretty much light up the neighborhood with it when it is on, and blinds cameras.
but singles is the way he uses them here. You can get them at HD, Lowes or any tool place .. called "work lights" best ones to use is the ones that are made by workforce in a blue and gray box.
