Isn't the electricity cost of those insane?

• TeMPOraL 4y ago
  That's some 3 KW of lightbulbs in total, based on original comment, and I'm not sure if the OP is running them all at the same time. Even if, that's in ballpark of household appliances, and I imagine it isn't running 24/7 (and most of those lights are likely active only during 1/4 - 1/5 of the year). Sure, it probably triples their power bill. But electricity is dirt cheap anyway - and if it mitigates their SAD, then it pays for itself. I'm also guessing OP doesn't have any problem with heating in winter. EDIT: I misread, OP isn't using 100/500W bulbs, but 100/500W equivalent - so the actual power use is not ~3KW, but probably under 1KW. It's very much in ballpark of combined use of household appliances, so I doubt it even doubles their power bill.
