Review on 660nm leds

[Acrofiend]

Hi I’m thinking I’m mixing some 660nm LEDs with 450 and 420nm LEDs on a bar.
I don’t want the red to overpower the blues. Does anyone use 660nm LEDs? If so are they noticeable in tank?

Yes they are noticeable, but they also promote algae growth.

Why?
Are you thinking about photosynthesis or just more color?

I’m thinking more about photosynthesis.

I’m thinking more about photosynthesis.

You may want to consider the " full spectrum" diodes.
They use a blue pump and a broad red phosphor and not too many of them.

I'd probably label it as " experimental"
