I have seen it both ways. Usually it is the bulb which is a few bucks. The ballast will cost more and could cost $15-$30 bucks depending on type. If you have another bulb that is working, swap it with the flicker light and see if the problem goes away. If the swapped bulb works, I always put the bad bulb in the fixture where the good bulb came from. If the bad bulb now works, you could have a seating problem with the bulb. If it flickers, replace it.
sure, it emits light as well as heat. the light from a regular light bulb is not sufficient for photosynthesis but may have an effect on photoperiod which can be a good or a bad things, depends on what you want to grow
You didn't say what kind of light which would have been a good clue. If a fluorescent it could be a bad tube or bulb, a bad starter or a bad ballast. If an incandescent light could be a loose connection or a disconnected filament that is making intermittent contact due to vibrations.
Its GOOD
No such thing as "bad bacteria" and "good bacteria" because they are all one and the same (though not literally) and can be affected by the same thing if the "bad" bacteria is targeted. A rod-shaped bacterium can be any bacterial species, "good" or "bad."
If one of the light bulb goes out, then the rest go out too.
If you have trouble codes and the build is known to be good, but will not light up, you have a bad power feed to the bulb, or a bad ground to it.
Bad news - there is no light bulb. The cluster is light using electro-luminesence, which means the entire thing needs to be replaced.

Bad bulb, no power, no ground.
no
fuse might be bad
It could be a bad bulb, it could be bad wiring, it could be a bad switch.
Bad or broken bulb OR bad seal to cover that protects the bulb.
Have you tried changing the bulb ? maybe the bulb is bad
If you mean the bulb failure light; The bulb failure detector compares the current drawn by the left bulb to the right bulb and lights the bulb failure light if the currents are not equal. I have never seen a bad one. The usual reason the light is still lit after the bad bulb is changed is because the new bulb is not an exact match or the contacts are corroded. Try two new bulbs. Good Luck
