The first 60-watt direct replacement, Premium Quality High Brightness (PQ-HB) bulb that uses less than 8 watts. The GeoBulb is the same size as a conventional incandescent bulb suitable for direct replacement in any indoor open fixture. It puts out more light than a standard 60-watt bulb but uses less than 8 watts. LED bulbs last 3 years of continuous use or 10 years at about 8 hours per day. Every part of the GeoBulb is built for long lasting durability. The GeoBulb is the first bulb built to withstand 10 years of use.

This bulb isn’t cheap: Buy here for $119.95.

ENERGY: Incandescent vs. CFLs vs. LEDs Light Bulb Challenge

IMAGE: Some comparisons of incandescent versus CFLs versus LEDs. Click the picture to download the Excel spreadsheet illustrating the information from productdose.com.

From productdose.com:

As a versatile bulb that burns comparably bright to a standard incandescent, but still costs less over the long term and burns more efficiently, the CFL Bulb may be your best bet. An advantage the CFL has over the LED is an upfront-cost that is considerably lower and far closer to the incandescent. In fact, if overall cost is your only concern, the cost of new LED bulbs may be more than you want to spend. Over the life of an LED, you are only going to see dramatic savings over the CFL if you are in an area that has high energy costs. For example, we compared LED and CFL bulbs at a standard $0.10 rate, and found that you would save about $11 over 60,000 hours. We also compared the two at $0.33 (what a friend pays) where the savings jumps to $120 over the life of an LED.
