The far light is the new LED 3 watt bulb. Same color as the 50 watt nearby. These are not really dimmable but my daughter likes them on full blast all the time anyway. There are 13 in my basement. 13 x 50= 650 watts verses 13 x 3= 39 watts. This is a savings of 611 watts. If on for 12 hours that's 7.3 KWh. Right now a KWh costs $0.11, or $.80 per day. But that's $292 per year or $8176 over the 28 year life of the bulbs!
