Re: 2 New Bee Questions...
The bees will fly toward white light at night but they also become crawlers with a propensity to sting. If you have a chink in your armor they'll pay it a visit, not bashful about crawling up your pants leg either. Go ahead and test the hypothis, the bees will give you up close and personal feedback.
You're overwintering hypothetical is focused on stores, aka a dearth. Read up on taking care of the winter bees and taking care of the bees that take care of the winter bees. Randy Oliver's Scientific Beekeeping is a good source. They can have all the honey they could possibly use but if your winter bees have been compromised by mites, forced to become foragers, etc, their chances of surviving winter diminishes
empirical observation, bees don't see red light but I've had some drawn to an LED headlamp; I assume there something about the LED bulb that allows them to get a bearing on the lamp
