Best PC color?

[Iplantz]

What brand of 65w PCs do you think have the best actinic blue? I need to balance out because of my XM 10k bulb. Price is somewhat of a factor

I like 450nm

[Iplantz]

Any brand you like in particular?

Coral Life 420nm. there is an article around here about 420 being better for your corals over 450. I think it was an old Gary Powell thread?

Ok thanks, coralifes on the cheaper side too isnt it?
