Light has a delay when turned on
I have a series of recessed lights when switched on, all the lights come on except one. This one does not come on but after a few minutes will come on. This light is not the first in series or last in series, and once it comes on, I can turn the switch off and back on and it will turn on immediately.
The bulb is a fluorescent bulb. All other lights in the run turn on and off instantly except this one.
Is this a light bulb problem or could this be caused by other reasons?

Some of the older compact florescent bulbs can take some time to warm up.
Have you tried swapping the bulb with one of the others and see if the problem follows the bulb or stays with the light fixture? This will determine if the bulb is the problem or the fixture.

He is saying "fluorescent bulb" and not CFL, so I believe this to be a tube situation, and yes it is definitely a bulb problem. Do the swapping thing to see if it follows you around the room. Once you do it, you will know. Replace the bulb and be done with it.
I had to do it for a client today. Her kitchen light would not work. Changed bulbs, no go. Knew then it was the ballast and told her the ballast was as expensive as a fixture. Wound up getting her a new fixture with T8's for $23 while the ballast for the old one was $18.

I am terribly sorry. It was a recessed light for incandescent bulb but I used a fluorescent bulb instead.
I have replaced the bulb with a new one and so far so good, but I have no idea if it corrected the problem because the original problem was somewhat intermittent.

I have found that manufactures of CFL bulbs perform quite differently. Some light instantly. Others take a little bit. I have even found a difference in different style of bulbs made by the same manufacture.
