Qual é a duração da garantia das luzes à prova de explosão?

Some explosion-proof lights come with a 5-year warranty. However, the typical warranty period for explosion-proof lights is 3 years.

As explosion-proof lights age, their light sources tend to diminish in strength. While some bulbs may last up to five years, the primary issue is usually with the light source itself. After five years, some bulbs may cease functioning.
