Re: night lighting

I went with a different approach for night-lights.   I've got a bunch of LED
providing the night-light for my tank.   It's a perfect low glow.   The fish
don't even notice it (if I turn it on and off).  It's just enough light to 
give a glow to the tank.   There is an article about it on my website.

The parts to build it cost about $10.00.   And since it runs on low
voltage DC, it's safe and easy to wire.

I've got a red filtered flashlight I use, and fish seem to jump at it as
much as they jump without the red filter.   I think the red thing doesn't
make a difference to the fish.

I'd think that a 32w (or 40w) tube is way too much light for a nightlight.
