What is the weak link with the lights? Is it the transformer, which could be replaced, or are the lights not properly sealed against corrosion? Our lights no longer work.

So far I've had no issues with mine. They've been in my tank since September and I run them every night for 2 hours and so far so good, no lights have dropped yet. Sorry I can't help anymore than that

If your transformer truly outputs AC you may not want this light. It will try to run on only half of the power half the time because the rest of the time the electricity is going in the wrong direction for this DC device, that will either make it run poorly or not at all. It will also likely shorten it's lifespan. Double check your transformer for output markings if it is an AC transformer with a rectifier that outputs DC then these lights should work fine. Mine have worked well for about a year or so. **Note** They don't like water so if you do use them make sure your fixtures seal.

Buy a new one. When these have anything go wrong, it is cheaper to buy a new one than try and fix. I had problems with the light on mine, and it was not the light, but something in the wiring. I purchased a new one from Amazon. Very happy

Any of the previous reasons could be the problem. Contact Cooper Lighting for a replacement, it has a 2 year warranty.

I would try looking through the ambx forums. Some users have worked through various issues with these lights and have documented their fixes. Make sure to download the latest software and follow their install instructions. Good Luck!

Leave them plugged in for an hour or so and recheck them. I believe I had a similar issue with these initially. I'm anxious to hear if this works for you. I've been really pleased with the lights I am using in our house. Helps so much at night.

The problem is either your voltage is dropping off or that you have "dirty" power going into the lights...you can solve the dirty power problem with a small capacitor between the power supply and the terminals on the lights

Mine worked for a few weeks the each light started going out. I think it might be something to do with the power box

It sounds as though there is moisture inside the fixture. You should remove the light to inspect for any sign of corrosion on the LED solder points. If none is obvious, the light should be returned to us for further inspection and warranty handling. Please advise.

Sounds like internal wiring issue inside the lamp itself. Make sure your connection has good ground. I'd try powering the lights with a separate pwr source, if they still don't work return for warranty.

Most items sold on Amazon have a 30 day return policy. I am curious as to why you think the transformer might be blown as it is built into the unit. One of the units I got had a dead remote battery so it wouldn't turn on the light. I used a new battery and the light turned on. Maybe try that?

I have had problems with CFLs and LEDs in this lamp. They burn out quickly. I believe it has to do with the transformer in the power cord.

I have no idea. I wonder if all the lamps are going to go bad. You can buy new cord etc at Home Depot.

You can connect them to any low voltage transformer. These lights are terrible as submersibles though. Mine leak and I really should have sent them back a long time ago!

Consider using multistrand, connector wire - it has less resistance. Check the current under various lighting conditions. Good Luck

I called Amazon and they gave me the number for the manufacturer. The manufacturer replaced the lights, but within a week the stopped working. There is a design flaw which causes too much condensation and causes the lights not to work. I am going to call them and see if they have a solution.
