That's a good point, I do hear that red is better than blue at night.
Blue is an awake colour and red resting. that's why computer screens have a red mode for night and we are told we should turn off our phones at night.
Its natural if one thinks about it. The light in the day is more blue, come sunset it becomes more purple then red tones.
I have my living room lighting on timers. (I still have main white lights, but do not uses them unless I need to) Starting with Cyan then blue in the day, then nice and overlapping with pink/magenta, in the evening to create purples and ending in pink/magenta, before bed.
But the blues i used for snakes were so dim at night it didn't seem to affect the snakes.
However, Taking on board your point, Maybe this time i could make the tanks the same as my living room. Blue for day and red for night? Would not be so gently transitional though and would require timers and two dimmer stats.
Also, yes I will stock up. I have loads still ok after 25 years as I said, when used on dimmers stats. I believe new low energy bulbs are not so eco friendly as they use a lot of carbon to make and contain harmful chemicals like mercury. if that got on your snakes or us, it could cause serious harm .
