Rated as a 12/19/28-Watt 3-way CFL bulb, it it the equivalent of a conventional 30/70/100-Watt 3-way incandescent light bulb, and it should fit any standard lamp that accepts 3-way bulbs, especially those of the open torchiere style. Just be sure that the base is the E26 medium screw-in standard. The big difference between this bulb and others is that it's rated at 6500 K (Kelvin), which is its color temperature.
Kelvin Color Temperatures:
Trying to not get too technical, color temperature is a description of the warmth or coolness of a light source, and describes the characteristics of visible light that have important applications in lighting, photography, videography, and other fields. Color temperature is usually stated in the unit of absolute temperature, the Kelvin, having the unit symbol K. Higher Kelvin temperatures (3600-6500 K) are considered cool, and lower color temperatures (2700-3000 K) are considered warm. Cool light is generally preferred for visual tasks because it produces higher contrast than warm light, while warm light is preferred for living spaces because it is more flattering to skin tones and clothing. Bulbs with a color temperature of 2700-3600 K are generally found in most indoor general lighting applications.
This Westinghouse 3-Way Daylight CFL bulb with its 6500 K rating is the equivalent of overcast daylight, and for some, it's the perfect light for work spaces. It does not have that greenish cast that we associate with conventional fluorescent tubes found in most office spaces. In comparison, the electronic flash used with most cameras is usually rated at 5,500-6,000 K, while Cool White/Daylight CFL bulbs are often rated at 5,000 K. Standard incandescent lamps have ratings around 2,500 to 3,300 K.
If you prefer a warmer 3-way bulb, the GE 47448 12/23/29-Watt CFL Energy Smart Spiral 3-Way Light Bulb is rated at 2,700 K, which puts it in the Warm White range. Others such as the Sylvania 29913 CFL replacement for 3-way lamps are rated at 3000 K. The choice is yours.
I've found this Westinghouse Lighting 3796300 3-Way Daylight CFL Twist Bulb to be an excellent light source as a work light, especially while on the computer or working with photos. Its light is clean and not distracting, and the fact that it's rated life is 10,000 hours is a plus.
As of this writing, in late 2014, these bulbs are difficult to find, and it appears that Westinghouse no longer manufactures them. I had purchased many of them earlier this year, as I was even finding them difficult to find then. Amazon had them, so I ordered to get enough to last me about 20 more years. They do not have them in stock as of this writing.
I highly recommend these Westinghouse 3-Way Daylight CFL bulbs, if you can find them at a good price. We paid about $13 each on our last order, which comes out to about $3.25 per year with significant electric savings over incandescent bulbs, that makes up the price difference.
There may be some newer LED Daylight 3-way bulbs available, but have not tried any yet.
Also - be forewarned - like other reviewers have said, this bulb's light is DEFINITELY more in the bright daylight, blue realm. I'm not scientific, so I won't go into the spectrum, but the light given off by this bulb was very blue - and very reminiscent of the blue given off by bare flourescent bulbs in an office environment. I knew when I bought the light that it'd be "daylight" but I never thought the light would be nearly this blue-white. I'm glad I ordered the Sylvania 3-way bulbs in this same order for comparison. Even though the Sylvania reviews say that light is "warmer", it's still a pleasing "white" light and not an artificial yellow light. I was definitely seeking white light for the room I bought the bulbs for, so I'm glad that the Sylvanias give me that without making the room feel - I don't know - like a hospital room. With the Westinghouse bulbs, my desk looked like a medical examiner's table - like from CSI, just sans body. Not the kind of work light I was looking for.
So - in summary - nice bulb that seemed to function fine (without humming) but EXTREMELY BLUE light. Also - in NO WAY "compact". I had to return them. For a warmer "bright white" light, I suggest the Sylvania 3-ways others have mentioned in reviews.
