So I've been having a ton of issues with one of my Halides. Jason and Luke at Premium Aquatics have been awesome in helping troubleshoot the problem and sending out some replacement parts, but thought I would post here to see if anyone has any thoughts on it.
I have 2 of these setups:
Lumenbright Mini Pendant
Radium 250w bulb
Hamilton M80 Ballast
The left side of the tank has fired first time every time and given me zero issues since day 1. The right side, however, gave me trouble the first week. Some days it wouldn't fire, some days it had no trouble. I had to remove the socket from the pendant and adjust the bulb sometimes to get it to fire, then reattach it to the pendant for the day. I had gotten some weird colored socket brackets from Lumenbright anyway, so I got a whole new socket and bracket to see if that would fix it. I think it seemed fine for a couple days then went back to giving me trouble. In the meantime, I swapped the ballasts to see if it was a ballast issue and the problem stayed on the right side. I then got a replacement Radium Bulb sent out from Premium Aquatics. Fire first try, and has been working great for 3 weeks or so.
I was on vacation this past weekend, and looked through my logs and noticed that on Feb 11th, only one of my halides was running for the first 1.5 hours of my photo period. 330w versus the normal 660w (thanks apex!). In addition to that, today the bulb didn't fire and I had to do the same thing I did before by removing the socket from the pendant, which allowed it to fire immediately.
At this point, I have a new socket, new bulb, and have swapped ballasts to ensure there are no issues there. The ONLY remaining item from the original issues is the Pendant. Could it be a grounding issue on the pendant? I think my next step might be to remove the socket and bulb from each pendant and completely switch them. If the problem stays on the right then I think it is 100% the Pendant.
All this being said, I love the look of the Halides, but am getting pretty frustrated here. Should I go back to my old favorite of mounting some nanobox reef pucks in an ATI fixture for my LED/t6 Hybrid? It is winter and I'm getting a 2 degree jump in temps with the Halides on for 5 hrs right now, so I'm a bit concerned that it will get worse in the Texas heat.
