Light bulb replacement


The bulbs in my 1.5 year old kitchen are starting burn out. They are GE 4-pin plug-in CFLs that use a GX24q-3 base. I went to lowes and it looks like the bulbs are $15 each; and I need 10 of them! Do you folks know of a more affordable supplier??

Also, shouldn't these things last for more than 1.5 years? That's only about 1100 hours assuming they are on 2 hours a day.

How many off and on cycles did they go through? A fluorescent, compact or otherwise, that is turned off and on frequently will not last as long as one that has not gone through too many turn-ons even if the latter has had somewhat more burning hours.

Are the lamps pointed or facing down with the ballast units directly above? Are the lamps enclosed by a shade or diffuser? This can result in a higher temperature inside that shortens the life of both bulbs and ballasts.

They are turned on and off pretty frequently. That probably explains it. They are pointed down (can lights) with no diffuser.

Thanks for the info.
