Rattler, you're right, I was under the impression electricity was more expensive. I guess I never did the math on my electric bill.
A 100W appliance run for 12 hours a day costs around 10 cents a day.
So, every 100W you add to your lighting setup is roughly another $37 per year. So it adds up, but slower than I realized.
If that $135 fixture is over 200W, after a year it costs the same as the one I listed. It still seems worthwhile.
