Rated 4 out of 5 by Cottage perfection from Abundant light Nice but too bright for bedtoom. It is three way however it is bright!

Rated 3 out of 5 by Ballard is Great from Fine Not as big of a range between the 3 brightness levels as I would like.

Rated 1 out of 5 by KCCookie from Not a 3-way Bulb I purchased this pricey bulb to avoid a trip to the store for the lamp I bought at the same time, which called for a 3-way bulb. It only had one brightness setting when I turned it on, so I went to the store to purchase a different one to make sure the lamp was not faulty. The lamp is perfectly fine but the bulb is not.

Rated 1 out of 5 by S Bert from Don't waste your time. These bulbs didn't last. Right out of the box one bulb did not switch to the 3 different wattages. Then a few days later the other stopped switching at all to the different wattages.
