Ultra LB18 Erratic Behavior

Hi, are the fixtures installed somewhere where they are always powered on 24/7? If so, that could be one of the causes, we've added language into our manual stating that most fixtures last longer if they are powered off when not in use overnight or during the day.

No, they’re not. They’re only powered when we need them.

About 3 or so months ago, we bought ten Ultra LB18s. For a while, they were working fine. However, for the past month, each one has been dimming off for some period of time or going to full brightness and fading back out. We’ve verified that this is not a DMX issue, and now I’m at a loss for what it could be.

Has anyone else been having similar issues? We already are sending one of them back for RMA because of having lime out in one of the cells.

I have encountered a similar issue with the Ultra LB18s dimming and fading erratically. To address it, I recommend reaching out to the manufacturer or supplier to report the problem and inquire about possible solutions or replacements under warranty.

I have the same issues with mine. They will intermittently turn off and slow fade back on. Seems like an overheating issue

At one point, I caught the screen on the status page, and the current temp said 100 degrees Celsius. After a quick power cycle, it went back to 26 degrees Celsius. As of now, I have still not gotten any reply to any of the emails I sent to ADJ. I won't be buying these fixtures again, since every single unit we purchased has the exact same issue.

That’s super unfortunate. I love the fixtures. The color mixing and CRI on the whites are fantastic for back lighting. They also have a such a fantastic spread for a bar light. I just need the issue fixed and I haven’t been able to figure out a fix. They are also relatively newer so there isn’t much chatter on them in general. For the cost, we should be able to expect them to not glitch out.

Hello all, I'm really sorry to see issues with these fixtures, and if they are within their warranty period you should absolutely be communicating with our service team by either emailing us at Rma@adj.com or calling into our service department if you are in the USA.
We'll be happy to work through these issues with you, just call or email us.

I've tried emailing them. Even the unit we already had RMA'd has the exact same issue. I'd say it might be a firmware problem, but at this point I'm still not getting email replies

Ok, I can look into this for you, is the email address you use for this forum the one you've emailed to us before?

It should have been.

Hi, i'm talking to the service guys now, and the email on your profile doesn't show up in our system at all for a RMA request. Is there a different email we could look up?

I didn't even get far enough to make an RMA request. I can try sending a new email?

At the same time, RMAing every unit isn't really an option. I can maybe send the worst one, but every single unit we purchased had the exact same issue

Hi, Rma email doesn't mean you have to send them in, it opens the line of communication for us to log the issues and keep a record of your issues and needs, if you didn't reach out to Rma who did you speak too in the service department?

I didn't speak to a person. I emailed support@adj.com, and never got any response.

Ok, i am still looking into this, and i will see what i can find out and update you here, or someone may email you directly.

OK, thank you

We have been having the same issue with all our lights. Any progress on a fix for this? Thanks.  

We have been experiencing the same overheat / random shutdown and restart issue. Any progress on a fix for this? Thanks!

If the fixtures are overheating, they may automatically dim or shut off to protect themselves. Check for proper ventilation and ensure they're not in enclosed spaces.

They're probably not actually overheating, since when you power cycle them, they are instantly 26 degrees

Hey All,

I just had a similar issue within the last 36 hours. I installed these in the ceiling of a heavy duty tent and left them on overnight. I came back the next day and 10 out of the 24 units installed were completely dead. Wouldn't power on or anything. They still passed DMX and power but the menu wouldn't turn on and they are dead in the water. Now I'm replacing a rig that's dead hung 20 ft in the air in the middle of the night so it's ready for tomorrow's event. Not cool, ADJ. These units have less than 200 hours on them. We bought them in March.

Any updates on solutions? Mine are getting worse.

Hello all, for service related or fixture issues troubleshooting, the forums are not the place for that, the best place to get help is to email to support@adj.com or to call the service department from the number listed on our website.
I am sorry for any issues, but we don't have service staff overseeing the forums. 

Someone from support sent me this sheet. They said to make sure both IR Remote and RDM were set to off. I had both of those on. I turned them off and for the first time in a while didn’t notice any erratic behavior with my fixtures this evening. Early, but so far so good. So just something to check and try for others having issues.

Thanks for this, I'll try it sometime this week
