Leviton 4 Channel VS Ratpac 12x200 for Quasars

Recommended Posts

Is there any reason why dimming quasars on a Leviton D4DMX would be bad for the units? Its just a much cheaper option than the ratpac LED dimmers for DMX. Thanks!

It should work quite well.

I haven't used the Leviton dimmer, but I used to have a couple of American DJ units which are very similar. They worked fine with Quasar tubes, except when dimmed very low. There seemed to be a cut off point after which the tubes just switched off abruptly. It was the same when dimming up from nothing, they would suddenly switch on, rather than fading up. I don't know if this was to do with the dimmer or the tubes.

Did you try ghost loading the dimming circuit with say a 25W or 40W tungsten? Found that can help sometimes with the sudden on/offs of quasars.

I never really looked into it, Adrian. On that particular job, I didn't need to dim the tubes all the way down, so I mentally filed the problem away for another day. Probably would have tried that had it been a issue for us.
