Do you, personally, really care about the energy efficiency of light fixtures?

If so, why?

If I were the city manager responsible for paying the electric bill for street lights, yes, efficiency would be important. Reduce the bill by 30%? Go for it! Works for home lights, too, but home lights aren't the biggies, usually.

I sure do, because I'm a taxpayer who helps to pay for the light that does me more harm than good. Moreover, the additional demand for power puts upward pressure on what I pay for the power I use myself.

And it's not just astronomy: I have to draw the curtains at night because the light from the sky here in Philly is literally bright enough to keep me awake.
