A while back I read somewhere (perhaps on the forum) about an idea to warm a hive in the winter using small light bulbs (~7 watt Christmas Bulbs). I believe the basic idea was to provide just a little heat to the hive to assist
the bees. Several bulbs could be used, if needed. The bulbs could be wired in parallel or series (I suspect) to help either increase their life or increase the heat output. Something would have to be done to protect the wiring and bulbs, but the basic idea sounds very feasible.
I don't believe the idea was to provide the bees with a heated hive, where life would go on like normal.......but, rather to create a system to help the bees to survive the winter. Something to assist them. Just as insulating a hive is suppose to help.
Has anyone taken this idea and built up a system?
Did it work ?
If not, what went wrong?
Outwardly, it seems with a little PVC, a few bulbs, wire and some imagination a simple system could be constructed.
I know that this is a bit early to be worrying about winter, but this idea is stuck in my head.
