Lighting Display

Background

While I was at TechAdvantage, I saw the light bulb display that Touchstone Energy was showing at their booth.

Bulbs

Here are the bulbs I selected. I tried to stay right around the 800 Lumens range. These figures are based on 3 hours/day, 365 days per year, at a rate of $ 0.12/kWh.
