Beware The Naked Bulb
While some manufacturers do sell the Projector bulb only without the cage, it’s not a recommended purchase for the average layperson. It can be a complicated process that should be done by a skilled repair person or at least by someone with a technical background. If you do try and change your light bulb, use rubber gloves. You don’t want any oil from your skin on the bulb.
Bulbs Burn At A High Temperature
These bulbs burn at such a high temperature that the area with the oil will be hotter than other surface parts and may prematurely burn out. The most important reason to avoid this kind of replacement is that many counterfeit lamps are sold as bulb only.
Phillips Replacement Bulbs
Phillips has authorized MI Technologies to sell their replacement bulbs since this company also manufactures its own cages. It’s this is a rare exception to the rule, however.
