Could it be that they are manufacturing them so they burn out quicker?
Everything is motivated by profit in this country. Would it be in the best
interest of a company to produce a bulb that last longer or shorter?
Interesting, I have two workshops one exclusively for wood one for rc
planes, both in my basement but 2 walls isolated from each other. My wood
shop has both 4' fixtures and 8' fixtures with 4' bulbs. I get much shorter
life out of the wood shop lights by comparison. They don't burn out, but
they start producing less light (not just from dust) and get black on the
ends. Hardly every replace the rc bulbs which are probably on more

I had no trouble with the last set of dual 4-footers. Bulbs would last
years and years. But I switched to new, electronically ballasted
models (at twice the price) in March of 2002 and just replaced my
18th effin' bulb within these 4 units. I'm not at all impressed. As
I replaced 2, I thought it might be a good idea to take the bad ones
back to the Ace store and let them run some tests on them. Maybe they
had a bad lot. I got a box of 30 which is now almost gone. Those in
the standard fixtures in the house haven't needed changing, so it
might be the stupid cheap electronics doing it. Either way, I need to
get it straightened out. One fixture just stopped working yesterday.

being 'picked' one time to be the maintenance man at a church
has disadvantages... BUT, ther was one room that had 15-4 light 4
foot fixtures in it, and they kept complaining the bulbs would
they were going down to the local HW store or Walmart and pay
$1.50 a pair (this WAS some years back), and complain when in 2
weeks they would burn out....
I ordered from an electrical supply house a BOX (24?) of the
better quality GE bulbs, paid the sum of almost $3 each...
the bulbs quit burning out... there does seem to be a difference
Dave, it might be worth finding someone with a line voltage monitor and
letting it run for a day or 2. It is possible to have spikes and excess
noise on you electrical service. I would think that it would also
effect incandescent bulbs but it is hard to tell.

How cold? I have three cheap 4 foot double bulb lamps that
I use a lot. The one above my work bench is used the most
and the bulbs have been in it for over 20 years. Another is

closer to the door (garage door that doesn't seal real well)
and outside wall and doesn't work well in the cold, has a
bad tube, and is unplug at present. Bulbs lasted about 6
years with a lot of use but I haven't used it much in recent
Wow! Everyone says their bulbs last a long time. Sometimes my four
footers don't last even 6 months. I checked voltage to them
today--115V. I haven't had any problems with all of my electronic
equipment or power equipment; just those bulbs.

I think it's the bulbs. I haven't fared well at all with the borg Phillips
"contractor pack" T12 bulbs, even though the box says "average life 20,000
hours". Replaced a couple after about 20 hours, most others at around 200
hours, which leaves me to believe that Philllips learned how to measure an
hour from lawyers working on class action lawsuits. Further I think the
"contractors pack" has nothing at all to do with number of bulbs in the box
but rather refers to bulbs designed to give just enough life for the
contractor to move onto the next job. Good news is that there are only 2
left in the last box I will ever buy.
Latest adds have been with T8 fixtures since it gets cold (like real cold)
here and the cold start is nice. Too early to say about bulb longevity but
they seem to be holding up well.
So I'm not the only one having to replace those bulbs more often than
should be expected. The last ones (note plural) were in a new fixture,
I double-checked my fixture connections because I was surprised that
both lights could have gone out simultaneously and so quickly. I've
replaced at least 4 others in the past year.
I'll have to start looking for a different brand after the remaining
bulbs are gone.
I've been using Wal-Mart's finest el-cheapo GE two-packs in Wal-Mart's
finest el-cheapo bottom of the line $5 shop light fixtures. I have some
bulbs out there that have been working since 1999, through all kinds of hot
and all kinds of cold. (The fixtures themselves are all new, owing to a
little wiring rectocranial inversion that fed their predecessors 220V for a
short time. BTW, don't try that at home.)
