Task Light just Flickers

I have a Luxo asymmetrical task light which takes an 18 watt bulb, which is
starting to give me trouble. Most of the time it will just flicker as if it
is trying to come on, but sometimes it will flicker once or twice and then
come right on. When it does come on it shines bright. Luxo will not support
this task light anymore because they say it is too old??? even though it
was supposedly guaranteed for life. What is causing this intermittant
problem and how could I fix it? I hate to throw the light out because it
was around $200 when I bought it and it does work fine after it lights up.

Uh, did you replace the bulb?

Indeed. This sounds like an intermittent filament. Assuming it's an
incandescent lamp.

Is this a fluorescent lamp? It could be the bulb, or the "ballast".

Or the starter? I've had several bug zappers with replaceable bulbs, that
did not get fixed by replacing them. Then I decided to ignore the "no user
servicable parts inside" stickers, and opened them up. Inside was a regular
floursecent starter in a socket for each bulb.

I've replaced them each time I've replaced the bulbs, which makes a makes it
a $7 repair instead of a $40 replacement.

Yes, these are big bug zappers.

No, but there are low-wattage tungsten-halogen lamps used in such products.

I'm guessing this is a halogen light.

That's what everyone seems to be doing -- guessing.

you've never seen any Xmas lights? they're less than 18W per bulb.
and any TEK scope with front panel lights;less than 18W incandescents.
same for any flashlight...
then there's my TENSOR lamp,with a 12v 12W bulb.

Arghh. It's a LUXO Task Lamp. 18 watt fluorescent, virtually by
definition.

The OP should have said so.

Ok I opened up the light..... the bulb is a Syvania Dulux D 18w compact
flourecent 20677 835 avg life 10,000 hrs
But I can not log into www.sylvania.com which is on the box to check the
specs?????
The ballast is made by B and L Tech. http://bplusl.com/html/balnu6.htm
mine is an INstant Start class P Type 1 NU6-1128-NT-1
It has a slight brown spot on it and so does the bulb.
Interesting that the manufact. recommends buying bulbs with EOL protection
built in them (end of life) to protect the ballast.
Maybe this is why my balast died because of the bulb going bad?
Any thoughts would be appreciated.

And what model of LUXO Task Lamp. They made a lot of models they
called a 'Task Lamp'.

There is a good chance that it has an electronic ballast.

I can't find the model number on the light - all it has on it is LUXO on the
arm

Mr. !
Thanks SO MUCH........ you just saved me some money........... I was
about to buy another ballast, cause of the brown spot..............
I'll try replacing the $5 bulb first......
I don't know if I"ll ever buy another Luxo again because they just told
me my Task Light was too old and they didn't support the product
anymore.....
I'm not an electrician so taking apart this light was no fun.... I had to
find all this out myself with your help......................
Thanks AGAIN
