fluorescent light lifespan and best value

lostinthewoods

It seems to me that I keep changing the fluorescent light tubes much more often than I should. The 4 foot straight compact tubes in my bathroom only seem to last four or five months. The circular ones in my kitchen and living room about the same.

I will know for definite since I have started using a CD marker pen to put the replacement date on the plastic ends of the tubes.

1. How long should they last?

2. Are there any brands or sources that last longer?

I have several fluorescent lamps in daily use in this house. They were there when I moved in twelve years ago. I haven't had to change a tube yet.

I think it's likely that your problem isn't the tubes.

Is the fitting a switch start fitting - has it got a round starter in the side of the fitting ?
If so then the starter may require renewing ?

Tubes should last minimum of 20,000 - 40,000 hours so in a house where its not on all day should last years, unless they are carp quality !

There are four things to try - cheapest option is to get an electronic starter, more reliable than a switch / glow starter http://www.e-lightingandheating.co.uk/fluorescent-starter-efs600-4-125w-electronic-tube-saver/p7265?source=froogle&utm_source=froogle&utm_medium=comparison_shopping_feeds&utm_nooverride=1

After that if that doesnt help the situation try a long life Triphosphur tube from a manufacturer such as Philips or Osram.

You could try a LED tube, but they are quite expensive !

Last thing to go for would be a High Frequency fitting, these are very reliable and quick starting and also save slightly on energy consumption which will also help on the lamp life.
