# What is the Polarimeter Lamp Life

## The lamp life (hours) is dependent on the amount of instrument use. This article will provide general guideline related to lamp life and steps that can be taken to extend the lamp life.

- The lamp life is 2,000 hours. If an instrument is powered on all the time (24hours a day) that would require a bulb replacement every 83 days or 4 times a year.
- To make the bulb last longer, they should turn the instrument off when not in use. If the instrument is turned off and customer wants to run samples, they should turn on the instrument and wait 10 minutes for the instrument to warm up prior to running samples.
