# Selecon rama 150 Fresnels

I have a group of Selecon Rama 150 6 inch fresnels that are not *really* working. Some of them seem to have wiring problems, and the lamps blow at alarming rates. We even had an issue when a lamp blew right after being replaced, and almost put a student in danger. Has anyone else experienced this problem, or does anyone have an easy (ish) and (hopefully) cheap fix? I will take anything I can get!!!!

Thank you!

It's been a few years since I worked with them but I had a problem with the sockets failing all at once. They kept losing the ability to hold the lamp tight enough in the socket which causes an arc inside the fixture and leads to premature failure. Remove the bulb on one that you recently changed the lamp on. Look into the socket. Do you see nice pretty shiny brass or do you see grey/black char/welding slag residue? Look at a failed lamp, do you see evidence of burning on the bottom tip? I had to replace a bunch of sockets in them. Call your local dealer. Strand overprices their parts, but I believe we found an Altman socket that worked for about $30 each. If you have a problem finding the right part send me a private message and I'll hook you up with my local sales guy who got me the cheaper parts.

If the lamp has a burned contact, it will burn that shiny, new socket up. #### Jeph H ##### Member This is an example of a lamp that failed because of arcing. I am having also having a problem like the one described here. Is there anything I can do to fix the lamp socket besides replacing the contacts? #### gafftaper ##### Senior Team Senior Team Fight Leukemia I am having also having a problem like the one described here. Is there anything I can do to fix the lamp socket besides replacing the contacts? Nope. Replacing the socket is the only solution. Once the socket starts arcing like that, it spreads destruction like a fast moving virus. Also throw away any bulbs that were in a bad socket working or not. As @FMEng said, you can damage a new socket by putting a char damaged, but working, lamp in it. New socket and lamp! #### gafftaper ##### Senior Team Senior Team Fight Leukemia Also note the other dead giveaway that this is your problem, the rest of the dead lamp is likely to appear new. Often, only the contacts look bad. RonHebbard #### C. Widner ##### Member It's been a few years since I worked with them but I had a problem with the sockets failing all at once.

Thank you so much! I believe that is the problem. I will check out our sockets and see what we can do with them - I may be in touch!!

Yep I have a rig full of them, it's getting really costly. Having to replace lamps, order new lamp holders and then only to discover that another load have gone. I've even got a pre heat on the dimmers jsut so that when they are used , they aren't initially going from cold to hot staright away. The fixtures are the bane of my working life. That and you can't focus with them on!
