renman303 Posted February 11, 2008 Share Posted February 11, 2008 Ihave a Nova Extreme T5 that has most of the LED's gone out in it. The remaining ones are dim. Has anyone successfully replaced these before? Dave Quote Link to comment Share on other sites More sharing options...
Headless_donkey Posted February 11, 2008 Share Posted February 11, 2008 If you are handy with a multimeter you can find the wires going to the LEDs and measure the voltage. If not there is probably a transformer in the fixture to knock down the voltage to something DC. That transformer most likely will say on it what the output voltage is. Find LEDs that are that voltage and splice them in. Remember LEDs only work one direction because they are a diode. Long story short, if you can get to the wires and know the voltage replacing LEDs in easy. Quote Link to comment Share on other sites More sharing options...

Thanks, I guess I was just surprised that they went out after having the T5 for only a year and them only being on during the evening? LED's normally have a huge lifespan, no?

Headless_donkey Posted February 12, 2008 Share Posted February 12, 2008 In theory yes, but I think your get what you pay for. Look at the LED traffic lights. They almost all have bulbs out. Quote Link to comment Share on other sites More sharing options...
renman303 Posted February 12, 2008 Author Share Posted February 12, 2008 (edited) Perhaps I should save myself the headache and get the moon lights that are independent of any other lights? I know Drs Foster and Smith sell them. http://www.drsfostersmith.com/product/prod...mp;pcatid=12110 Dave Edited February 12, 2008 by renman303 Quote Link to comment Share on other sites More sharing options...
GKarshens Posted February 12, 2008 Share Posted February 12, 2008 I took the moonlights off my tank. Unless you enjoy looking at the tank under them I don't think they really serve any purpose. I know there are people that are fanatical about it thinking it is for coral health or spawning, but I really don't want anything to spawn in my tank.

Headless_donkey Posted February 12, 2008 Share Posted February 12, 2008 On a side note. Have you ever actually met someone that there corals spawned? I have heard the, "this guy some where...10 year old tank...tank crashed" story, but is there any hard personal evidence? Quote Link to comment Share on other sites More sharing options...
+ACampbell Posted February 12, 2008 Share Posted February 12, 2008 [sorry to continue the sidetrack] I knew a guy in Lubbock that had a certain sps the spawned. He hated the stuff and was constantly chipping away with the hammer to get it off everything. It was defiantly a nuisance. Quote Link to comment Share on other sites More sharing options...
