Hello all! I joined this board mainly because I want to learn about this vintage Fresnel fixture I picked at a HAM fest for $12.00 I'm well educated with moving mirror, moving heads, and vintage disco lights but not as much when it comes to theater specific lights like this one. It came with a Chinese copy of an Altman clamp, a new safty cable, and the Fresnel fixture without a lamp. I bought it for the clamp and the cable but I always wanted to domesticate the Fresnel to use as an accent lamp in a room to light up a picture. Recently I repainted and redecorated a room to look like a coffee shop / jazz club so I started working on this Fresnel. I took out the old socket and reflector and mounted a 120v 50w MR16 bulb in its place. I want to aim the light on a 3D metal wall decoration however the way it is now it hits you in the face when your trying to watch TV. I thought of getting barn doors for it so I can crop the light out of my face but I have no idea what Barn Door will fit this light. So far I've spent an additional 25.00 on this light. I'd like to repaint it too however I'm not sure what type of paint I should use on it. I'm mainly interested in learning about what modern Barn Doors will fit on this thing. I reuploaded the photos using the forum's upload feature. They are attached below. The 6th photo shows a tape measure in front of the gel holder slots. Its roughly 8 inches.
