What is the lifespan of a 2100Q lamp?
2100Q/P lamp lifespan
There is not an exact specification of the lamp lifespan for the 2100Q or 2100P. The life expectancy of a tungsten lamp in continuous use would be approximately 5100 hours. This does not apply to intermittent use, which is how the 2100Q functions. Lifespan during intermittent use is difficult to predict as it is dependent on number and duration of cycles. The temperature of the filament also affects the in-rush current of the lamp. Hach Company recommends that preventive maintenance and factory calibration be performed annually. During this process the lamp will be inspected and replaced as needed. Please contact Hach Technical Support to initiate this process.
