The red lights kept my chooks up all night, too.
I have the ceramic heat bulb - 250 watt - and love it. Heat without the light. It stays on 24/7 here in MN. Got mine on ebay - about 50% cheaper as long as you don't need it, like, yesterday. You can get lower wattage bulbs in most pet stores that sell reptile stuff.
BTW, my girls are very comfortable at 10 degrees, which is where the interior of my coop has been sitting for the last few months. It's when it drops below zero in the coop even with heat (and sometimes 2 heat sources) that I start getting a little worried. And that has only happened a couple of times. So far, no frostbite here.
As long as your coop is draft-free, then mildly freezing temperatures are not that big of a concern. If the red light is keeping your roosters awake and naughty, then I'd turn it off. They'll be okay.
