Replacing lamps
Incandescent lamps fail over time. Therefore, they should be replaced with new ones every 2 years, even if they still retain their functionality. This does not apply to halogen lamps, which, for example, are used in headlights. As a rule, their resource is much higher and they should be replaced only when they fail. The weakening of the luminous intensity in incandescent lamps is determined by the black deposit on the glass bulb.

Wipe off any accidental touch marks with a clean, lint-free cloth or alcohol.
