gu10's for nightlights....

[slowngreen]

I wired up two blue gu10's over my 75g to use for nightlights, think it will be too much light for that and give stuff that needs light like algae enough to grow at night? Its not very bright but I thought I better ask before I find out in a week its just feeding bad things.

Is it this bright?

 

[slowngreen]

No not that bright and mine are only 3w.

Post a pic if you can.

 

If your corals, etc, are open and active, then I would be worried.

Some of my zoas are open about half way.

Others may disagree with me, which is commonplace, random, or generally accepted, but I think that is too bright.

 

If the zoas are reacting, it is too much.

 

I always aim for a very faint, very low blue glow...in which you can hardly see the tank.

I love the effect but I agree that if the corals are reacting to the light it;s probably too much.

[slowngreen]

ok thanks, I'll remove them and go back to my stock nightlights.

You could always remove the lenses to reduce the intensity.

[slowngreen]

Yeah? So it would lose the focus right? MIght have to give that a try. Just have them laying around so thought Id try to do something with them.

The area of coverage would increase by quite a bit. Those are most likely 40-ish degree lenses. The stock LEDs are around 120 degrees, not counting for any of the housing blocking the light.
