Question
How often should the DR 3900 lamp be replaced?
Summary
DR 3900 lamp replacement interval
Answer
Lamps are rated in hours but this is only useful on an instrument that keeps the lamp on as long as the instrument is on, this does not apply to the DR 3900. There is no specification for minimum switch cycles, although this can be viewed under the lamp history. The lamp has a 6 month warranty.
