How the 420nm look?? I want LEDs mixed with 420&460??
Personally I think the 420 would look nicer cause they are more purple like black light making your corals stand out more, do you see a diff?
 
I'm very pleased.. I see a huge difference in blue .. I honestly wouldn't mind running four of these bulbs I like them so much
