Don't know if anybody would find these useful. It's PAIR of lights that I took from my mom's work when her lab closed down. I thought I could use them but never found a use for them. Her lab was using them to take shadowless pictures of objects. Here's a picture of one of them. Free to anyone that comes out to Upland to take them them. Otherwise I can drop them off for you in return for gas money or lunch.
AFAIK the lights can use normal light bulbs. I've got 4 of the little shades even though there is only 1 in the picture (one fore each light). The lights CANNOT be pointed toward or away from each other but CAN be slid up and down the arm and rotated about the axis of the arm. The arms have 2 quick adjust elbows and the shiny metal tubes are held by bolts and can be turned if you loosen the bolts... I think... Lights mount by clamping on the table. They're pretty hefty so make sure it's a sturdy table. Also, for reference, the lights are about 14" apart from each other (center to center) in the picture so that puts the whole thing about 2' long.
PM me if ya want them.
edit: Gone... Wow, that was fast.
