What is the advantage of Xenon bulb over a halogen one?
Principally, it’s a question of life. A Xenon bulb is expected to give around 10,000 hours of life which on a vessel or in a caravan occupied only part of the time, should represent many years! They are obviously slightly more expensive than the equivalent halogen bulb but the extended life may pay off in the long term. Xenon bulbs are apparently more robust than halogen bulbs but we have never put this to the test!
