Was thinking of trying these on my scrubber since I have to replace a bulb and want to upgrade.

I've tried some but not that one. Is real important to heat sink.

Some of them have a clear coating, and they are bright. But some like the one you linked, I think has an orange coating to just convert white LEDs into pink, and they are very weak. You might try other that don't have the orange coating.

Just look at all their pics. Problem is that they may send you something different.
