If the light is just to see the snake, and not for temperature, what about LEDs?
I don't use lights for my snakes, only the red heatbulb for our leo. But I have a superb LED torch I use at work on nightshifts, and have had to prise it back from several Drs borrowing it to test for pupil reactions because it's so bright. So, nope, not quite a genius, just a little lateral thinking. That's why I said I'd have no idea if it would affect the temp in the OP's viv.Right, you rock, Janine! Thanks for that, I'll soon have some red leds in my viv. Have you seen that before, or are you somewhat of genius?
Also, the day glo will only be good for lighting for the viv...during the day.
If you want to see your snake at night it *HAS* to be a red light as they can't see it.
