Can you please explain why many people seem to prefer LED lighting over incandescent lighting with regard to their use in densitometers and spectrophotometers?

Probably the most compelling reason for choosing LEDs is their longevity in that they can last up to 10 times longer than incandescent lighting ; in many cases up to 50,000 hours or longer.

They are also very rugged and can withstand a significant amount of vibration and impact that is often found in most industrial applications. LEDs are also much cooler and do not as a result suffer from the thermal expansion of the glass cover as found with incandescent lights. LEDs are also much more efficient by converting electrical energy directly to photons and can be manufactured to cope with many different measuring conditions by mixing multiple LEDs together to provide a wide spectrum of coverage. Finally LEDs have much greater stability, turn on very quickly and provide a constant output over along time.
