This 13-watt spiral GU24 CFL generates up to 70 lumens per watt to replace a 60-watt incandescent light bulb and save up to 75% in energy costs. It has a warm 2700K color temperature that is similar to incandescent light and a long 10,000-hour life that reduces replacement and maintenance costs.
The light output for this bulb is 900 initial lumens; average of 750 lumens throughout the life of lamp.
I have only had the bulb for a couple weeks but it seems to be working fine. I am really impressed with Pegasus Lighting though because they had an excellent price, free shipping and I swear it arrived in two days!! I will definitely use them from now on.
