We guarantee that all Cobalt Projector Lamps are made with 100% OEM bulbs and reflectors/burners from manufacturers such as Philips, Osram, Phoenix and Ushio. You can always expect to get a bright, quality image and a product that lasts the test of time.

  • High-quality guarantee
Cobalt Lamps must pass rigorous quality control measures before they are shipped to you.

Beware of Generic Lamps. Projector Doctor does NOT recommend or sell low quality generic projector lamps. Generic projector lamps are built using the substandard components and build techniques that result in a dimmer and shorter life for the lamp. These low-quality lamps can damage the projector itself causing safety concerns and voiding your projector’s warranty. The pricing on these lamps can be very attractive, but you will get what you pay for. Buyer beware.

OEM lamps (i.e. lamps directly from projector brands/manufacturers with brand label) available upon request.
