Arri ceramic 250w problems

Recommended Posts

Hello folks, 

Just wondering if any one could shed any light on this. I have a arri 250watt ceramic with the correct bulb which is very specific. It worked fine one I put it in but then I handt used it in a while and the unit now give out a very load rattle noise one I hit the on switch. I wondered if anyone new what this could he and how I fix it. I really loved this light and turned out to be a very useful part of my kit. Any help appreciated.

sounds like a wire has come loose and is making contact with the metal housing but not making a Ground Fault , which should trip the Circuit breaker.. Not good.

Do not continue to use.

That rattling sound- is it more of a buzzing?

Sometimes discharge lamps of all kinds do buzz, especially if the ballast is switched to a flicker free mode. Can you record it, maybe upload it somewhere?

If it's more of a harsh rasping that might be electrical arcing, that's alarming.

Hi Guys 

 I will upload a video of the buzzing sound as well just in case it's a lose connection or something simple. Really hoping it is as this was a very useful light especially as it has a low electricity draw. I am very thankful for the response to this post.
