LED Diodes Replacement

[Juano908]

I just noticed there are 7 diodes not working properly in my full spectrum adjustable Chinese LED lights, they are on the blue channel and by not working properly I mean not fully lightened up like the rest of the diodes, plus when the fixture is off they look burnt.
I don't know for sure what kind of color temp these diodes are but I'm suspecting they might be royal blue. As I've mentioned before they are on the blue channel and they are only 7 but the rest are working properly.

Here is a pic of them off, any input will be well appreciated.

I went through the same issue and @Chrisgarrick showed me how to replace them. I bought a selection of blues from Reefbreeders.com and swapped them out with a soldering iron. Its a good time to adjust your spectrum at the same time if you want to.

The only thing to really look out for is alligning the polarity correctly. There is a "+" and "-" to each diode and it must be placed in the proper orientation. You can use a "AA" battery and some wires to see which side is which. It will only light when + from the battery is aligned with + on the diode. Then it is a matter of placing the iron on the small tabs to release it and do the same to attach it. I know someone on here has a thread with pictures that walk you through it. Maybe they will chime in.

Thanks, I have no problem replacing them but my main concern is what color temp they might be, I checked Reefbreeders but they are on back order.....any suggestions of what color temp to use taking in consideration they go on the blue channel?

I had the Ocean Revive and there schematic was posted on there website so I knew what colors were out. The were all either 420 or 450s Im pretty sure you can order the same 3w leds from Amazon at a cheaper price.
I eventually gave up on the fictures because they would continually burn out. I had 4 and all 4 had the same problem. I know run T5s and like the set and forget about them. No fiddling with intensity or spectrum. Everything grows much better now.

Thanks again, I run T5 too for supplements.
