I am using a couple of lightbulbs for the test load for my solar testbed. I was using either one or two standard bulbs which consume maybe 10W each. Not much of a load really. I started looking around for something a little bigger and realized there wasn’t much that you can run 24 / 7 that uses much electricity. I happened to have two old incandescent bulbs that weigh in at 60W or so each and they are about the best I can do.

Funny thing is the 10W LED bulb puts out about as much light as the old 60W incandescent. That’s significant. It certainly makes things like home solar much easier to manage. The idea of “keeping the lights on” isn’t such a big deal. The next step, I suppose, is keeping the A/C (or heat) on.
