donnob Posted January 13 Share Posted January 13 (edited) Hey guys, want to know if anybody here has some advice for me. I have a @Light It Up 240W QB and lately it's been much dimmer than normal with random flicks of brightness every now and then. Could it be the driver packing up? Maybe the dimmer is not functioning properly? Maybe the diodes? I have the multimeter attached and the dimmer is on full yet it outputs less than 50% of what it normally did. Anybody have a clue of where to start looking? After a week or 2 I should have a gap between runs to take the light out and troubleshoot.

I read on a previous thread about the meter box thingy was giving some guys problems so they disconnected it.My wattage fluctuates ever so slightly but my electric experience tells me to leave shite alone until I know what I'm doing.Reach out directly to @Light It Up, the guys are supper helpful.Sent from my S40 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Aha, never thought about the meter box being out of whack, another thing to check. Thanks for that 1 Quote Link to comment Share on other sites More sharing options...
ORGANinc. Posted January 14 Share Posted January 14 Its most likely the dimmer, same thing happened to my QB. To test, connect the unit directly to the power source and leave the dimmer disconnected, it should run at full power which would be easy enough to see. 1 2 Quote Link to comment Share on other sites More sharing options...

The_StonedTrooper Posted January 14 Share Posted January 14 I had a light with same issue, cut the dimmer off and it worked full power, no flicker anymore. Try that? 1 Quote Link to comment Share on other sites More sharing options...
donnob Posted January 14 Author Share Posted January 14 Cool, thanks guys, I'll bypass the dimmer and see what happens, that's easy enough to do. I'd be over the moon if that sorts it out! 1 Quote Link to comment Share on other sites More sharing options...
CreX Posted January 14 Share Posted January 14 i have had a bit of issue with the dimmer unit as well, but can confirm that the LED panel, and the Power supply are absolute quality and will likely outlive the rest of your electronics haha. its just the knobby dimmer that seems to give issues Quote Link to comment Share on other sites More sharing options...

donnob Posted January 14 Author Share Posted January 14 Would it work if I just disconnect the... p-o-t-e-n-t-i-o-m-e-t-e-r ... from the quick connector? Or does the loop need to be closed somehow? 1 1 Quote Link to comment Share on other sites More sharing options...

Prom Posted January 14 Share Posted January 14 Shouldn't it go off when you join the dimmer wires? Open is Max.. closed is off.. as I understand. 1 1 1 Quote Link to comment Share on other sites More sharing options...

Open is Max.. closed is off.. as I understand. sort of, open circuit ie infinity ohms is full current, but if you short the wires, nothing happens - it needs a PoTeNtOmEtEr with a specific range of ohms to operate the dimming function i think its 100 ohms 2 Quote Link to comment Share on other sites More sharing options...

Dookie69 Posted January 14 Share Posted January 14 Might as well remove the meter seeing as its only there as an indication of the dimming (and by inference, the PPFD) 2 Quote Link to comment Share on other sites More sharing options...
Light It Up Posted January 17 Share Posted January 17 Sorry for getting in on this a bite late, we do not check the forum everyday but do monitor our emails daily. If there is ever anything urgent, best to drop us an email. We see the issue has been resolved by removing the pot / dimmer. We have been experiencing some issues with the dimmer and got a new batch of dimmers from our supplier which we are now making use of and busy testing. @donnob Drop us a PM and let us know if you'd like some replacement dimmers and we will happily send them through to you. 1 Quote Link to comment Share on other sites More sharing options...
