Lighting fixture: Replace or Repair?

I have a SolarMax HE 2 bulb 42W (21x2) T5 fixture. The problem is the 6700k bulb barely lights up. Are these units repairable and worth doing so? Or do I need to buy a new fixture?

Hmmm have you tried replacing the 'starter' if it has one (the little cylinder thing... I'm so technical :/) a lot of times that's what keeps things from fully lighting (if it's fluorescent).

If it's LED I say replace teh whole thing they're usually more trouble to fix than others.

It is a T5 fixture which I believe isnt florescent(?) and has 2 seperate switches for each bulb. The bulb only partially lights and is VERY dim. Im an electrician and not afraid to tackle a repair if its possible but if its not or not worth it, I guess Im looking at a complete replacement?

T5s come in Fluorescent and LED :)

Does it do that with any bulb you put in there? I've gotten a few bulbs that were deadish when I bought them.

The ballast might need adjusting too, I had to do that with ours because the ballast was damaged at the lights would come on and off and flicker. Maybe it's not getting enough electricity to that bulb because a bad ballast? Just another idea. Not sure if you can get a replacement for that bit if it's bad.

I havnt tried any other bulbs. They do resemble thin florescent bulbs so i guess it is possible it is a florescent fixture. I think Im gonna disassemble the unit, see if there are any lose connections or corrosion on the contacts. If that all checks out ill try replacing the bulb.

Went to a lfs today. They had my fixture in stock along with replacement bulbs, though not the one I need. So its pretty safe to say I can replace the bulbs if needed. What a relief as those fixtures are not exactly cheap lol. But I have a question though. Can I use higher wattage bulbs? Or do I have to stick with the 21W bulbs it came with?

I think it depends on the fixture and what it's rated for, most of the time the higher wattage gets too hot though even if it can handle it.
