The Greenlite Lighting 11/20/26W/3WAY/35K 3 Way Dimmable Spiral Bulb is a 3-way Compact Fluorescent bulb that performs at 11 Watt, 20 Watt, and 26 Watt, which is equivalent to 40Watt, 75 Watt, and 100 Watt incandescent bulbs. The 3 Way CFL Bulb features smooth dimming IC controlled and is flicker free. The CFL Spiral Bulb uses about 1/4 the energy compared to incandescent bulbs and costs less to operate. A Greenlite bulb equals 6 standard incandescent bulbs and lasts up to 10,000 hours. Ideal for table lamps, floor lamps, ceiling fixtures (if ventilated), closet lights, and desk lamps.
This product is also available in 12/23/30W/3WAY 3 Way Spiral Dimmable CFL Bulb.
What is a CFL?
A compact fluorescent light bulb (CFL) is a type of fluorescent lamp designed to replace an incandescent bulb. CFLs are the most energy efficient lighting available. Like other energy-efficient products, high quality CFLs bear the Energy Star symbol, demonstrating to consumers they are among the most energy-efficient on the market. Energy Star-approved CFLs, such as those produced by Greenlite, must meet numerous requirements that include: using at least two-thirds less energy than standard incandescent while providing the same amount of light; lasting 10 times longer than incandescent; saving $30 or more in energy costs over a bulb's lifetime; and generating less heat than incandescent bulbs.
CFLs Environmental and Economic Benefits
Regular incandescent bulbs waste energy: 90 percent of their energy is used to produce heat, not light. CFLs save energy and help lower electricity costs because they use 75 percent less energy than incandescent bulbs, thereby requiring only one-quarter of the energy consumed by incandescent. For example, a 13-watt CFL produces the same light as a 60-watt incandescent bulb, saving about 45 watts each hour it is lit.
Estimates show that if every person replaced just one incandescent bulb with an Energy Star CFL, greenhouse gas emissions would be reduced by about 400,000 tonnes each year - the equivalent of taking 70,000 cars off the road each year.
The average home has about 30 light fixtures that consume about $200 in electricity costs each year. If just five incandescent bulbs using three hours of light each day were replaced with Energy Star-approved CFL light bulbs, a homeowner could save $30 each year.
CFLs help to save the environment in other ways too. Because Energy Star CFLs are required to last 10 times longer than incandescent bulbs, fewer bulbs and packaging are sent to landfill sites. And using less energy and fewer bulbs reduces emissions from power plants and helps protect the environment from the risk of global climate change.
CFLs and Mercury
CFLs are perfectly safe to use in homes. Each bulb contains a very small amount of mercury -- an average of three milligrams - about the same amount it would take to cover the tip of a ballpoint pen. The mercury dissipates when the bulb burns out, leaving no harmful toxins. There is no health risk if a bulb breaks because the amount of mercury is minute and in vapor form so it dissipates immediately leaving no harmful toxins. As Energy Star states, when a CFL breaks there is more harm from broken glass than mercury. Currently, using mercury in the manufacturing of the bulbs is necessary because there is no other substance that can replace the efficiency properties of mercury to produce fluorescent light. However, in recent years the mercury content has been drastically reduced and research is underway to develop bulbs that use even less mercury.
Safe Disposal of CFLs
Ideally, CFLs should be recycled. Many municipalities accept CFLs that are placed in plastic bags in the blue recycling box. However, regulations on proper disposal of CFLs differ by province. Check with their local municipalities to inquire about disposal programs and regulations in their area.

Review of 903236
I was surprised that it actually puts out as much light as a 75 watt incandescent light bulb on the highest setting and that it was dimmable with a conventional in wall dimmer switch, that's because it has a chip in the base that converts the duty cycle of a conventional dimmer switch to variable current flow of the newer CFL dimmer switches and it works quite well!

The exact right color( 3500k) now we just wait to see how long it lasts. A CFL I keep on 24/7 ran continually for 537 days. I like it.
