Cheap LEDs to rebuild a RB BB

My Reefbreeders BB light over my sump has chared the blue LEDs. I've already replaced the light with another cheap one, but would like to remake this one to work again.



Buying individual LEDs from TopLedLight is a bit expensive. This is the quote I got, which would replace all the LEDs plus some extras to play around with.
13pcs 4500K neutral whites
6pcs 480nm blue
6pcs 420nm violet
2pcs 660nm deep reds
28pcs 450nm royal blues
4pcs 400nm UV
4pcs 520nm bright green
Total: USD 91 including shipping by registered airmail.
But at that price I could buy a new light, and have all new metal and drivers, and not have to spend a few hours over a soldering iron too.

Does anyone make a rebuild kit for them that just has the cheap LEDs in a kit?
This is just a sump light, so exact spectrum is not critical.

just replace the blues.. that spectrum (wavelength) cooks the cheap lenses on those in a short time..
the others will last a long time..

Great, thanks- Don't know why I didn't look there. Guess I was hoping someone had put together a kit to remove some of the risk of selecting the wrong parts.

These look OK?

Thank you, parts are on order. I'll post again when I get them working.

I just ordered the blue LEDs, although I suspect that some of the others are getting weak too.

Got the LEDs in, and work as expected. Used a Metal (high power soldering iron) at work to get them replaced.



Put it on the tank last night, and everything looks good for now.

Thanks for the help-
