Tis the season - for new LED lightbulbs!

Today is the day to use those gift cards you got to help save yourself some money and the planet too. Based on this morning's trip to Home Depot, I have updated my lifetime cost calculations for LED/CFL/Incandescent bulbs. The chart is based on recessed lights, 65-75W equivalent R-30 bulbs, 5 yrs use per day, $.12 kWh electricity price. These lights are very common in the houses in my neighborhood. The LED bulbs are down to $30 each, so get our there and replace those old bulbs!

On a related note, 40w equivalent LED bulbs in A-19 (standard bulb shape) are selling for only $10 a piece. This is a great deal - I got 5 of these today for a dimmable fixture and they work great! Anyone care to work the payback numbers for those? Please leave a comment if you do!

  1. Many people prefer recessed led lighting for a number of reasons. These are the lights of modern times and used for a number of objectives. Why do people prefer so much? First, the intensity of these lamps is quite high and compared to conventional lighting. So you need a small amount of these fires.

  2. The led ring light is the best quality of led lights. BMW have proper lights angel eyes to some models of more than 10 years. They are just rings of light around the outside of the beacon can be activated independently of their own flashlight. Replace the side marker lamp more conventional. Angel Eyes are sometimes also known as Corona rings.
