Hella marine bulbs are top quality products sourced from leading international bulb manufacturers.
Incandescent bulbs, also referred to as ‘standard’ bulbs, produce light by heating a filament until it is white hot. Incandescent bulbs become progressively dimmer over the course of their service life, because heating the filament makes it slowly burn away, with residue settling on the inside of the glass envelope.
