Are these bulbs dimmable?

Asked by: SamB
No. I tried two different brands of dimmer switches and neither worked for my 50 bulbs in my basement ( all on same circuit.) I sure wish they were dimmable, because my basement lights up like WalMart ( too bright).

I live in California and the rainy season starts in November. Whenever the humidity reaches 50% or higher, about 40% of the bulbs do not light. I have to toggle the on/off switch numerous times to get them to work. The previous bulb worked 20 years in the same environment without a hitch. I am replacing the bulbs from Ace Hardware since they do work under my environmental conditions.

When you buy linear fluorescents as these you might want to consider the "color" of light it puts out. Cool White (4100K) is bright white. If you have a workshop you might like these. If you need some for your office you might consider a Soft White (3000K) which are not as bright white but a little more amber and easier on the eyes.

Rated 5 out of 5 by from Replacement bulbs for shop light and ceiling troffers This is the second time I have purchased these bulbs from Home Depot. I have 4, 2 bulb shop lights in the garage and 25 ceiling grid mounted 4 bulb troffers in a studio area. The bulbs are bright, last a long time and are reasonably priced at Home Depot.

I LOVE this item....it provides so much light and it lasts for so long - it's a good investment. I am not constantly replacing light bulbs with this item. Easy to use, easy to install/replace - will definitely purchase again (when that time comes)....

Maybe my previous purchase of ALTO bulbs were duds as it didn't last very long, a few years (supposed to be 24000 hrs-3 hours a day = 21.9 yrs.) and considering there are no choices from HomeDepot (like our healthcare) I had to buy these.

It is the only one wattage and size that works in my garage. I have light in my garage now, after several weeks of looking for the right bulb.
