Help Repairing My Aquarium Light

[Eb0la11]

Hey guys,

my FW tank aquarium light seems to have finally quit working. I'm not sure what is wrong. I have changed the bulb to a new one and it still is not working so it's not the bulb.

It's a very simple 40W FW 4 foot lighting unit.

I've taken it apart and took a couple shots of the interior components tucked behind the reflector, they are below.

What component do you think may no longer be working?
Where in Calgary can I take it to be repaired or buy the necessary parts?

Is it an electronic ballast? (do you need to hold the button down for it to fire up or does it flicker and fire up itself?)

If you have a multimeter I would first check the switch to make sure that when you turn it on you get conductivity if so check that the 2 connections to each post of the light are still good. If everything checks out I would guess it is the ballast. A replacement ballast can be found at larger hardware stores (Rona - HD) or an electrical supply store.

Hmmmm, it doesn't flicker on like my MHs on my salt water tank. It just clicks on.

I can't really test anything as I dont have the hardware.

The ballast says its a class P ballast and is an s40BP Robertson ballast, I believe.

Should I just take it to a shop and pay to get it repaired? I prob wouldn't wanna pay more than like 40 bucks for a repair though. Think thats possible?

Depends on the light, I had one that wouldnt work on me and was thinking of doing that, turned out to be a 50 cent starter. (small cylinder shaped piece) If its a good shop they should be able to tell you wether its worth it or not to have it repaired as its pretty tough to diagnose with no tools. Is the light run on a timer?

Yes the lights run on a timer. I've unplugged it form the timer and tried a working wall socket with no luck as well.

hmm well without the tools to do the tests joe suggested your pretty much shooting in the dark. Best bet if you dont want to get the tools is to look into repair costs vs new cost. Any electronic repair shop or possibly a lighting shop should be able to tell you wether or not its worth it. Sometimes if its a ballast, you factor the part, plus there time and you could of bought a new light.
