I bought a Lithonia T8 32 watt light. Will my old Philips F40cw 34 watt bulbs work in it.?

Asked by: Kevin
No because the ballast is different. T8 bulbs wont work in t12 fixture without changing ballast.

What is the correct name for the holders or connectors that you mount the two pin t12 40w 4 ft. flourescents bulbs on?

I'm having trouble doing a search for them on your site.
Asked by: veteran63
It’s a G13 fluorescent lamp holder. You can probably search by T8/T12 fluorescent lamp holder and get the same info.

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.

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.
