Tips from our experts
- Inferior UV filters – inadequate filtration of UV light can cause permanent damage to the projector color wheels (which can melt) and critical optical components, cracking integrator rods, fold mirrors, and prisms.
- Lack of thermal couplers installed in-series with lamp wiring – this results in insufficient fan speed, creating excessive heat which can melt fans, wiring, and color wheels, or shatter UV filters and internal optics.
- Defective lamp timers - inhibiting “Lamp end-of-life notifications and alarms”. Inadvertently running lamps beyond their rated hours of operation creates the potential for lamp explosions, which often causes damage to optical components including color wheels and integrator rod assemblies.
- Lamp anode and cathode wiring or connectors that plug into the lamp driver installed backwards/upside down – causing failures of the lamp driver assembly or the DC power supply. Replacement of those parts, along with the lamp will be required to restore functionality.
The pictures below provide examples of the damage non-DP Certified lamps can cause to customer-owned projectors. Clearly, the best solution is to always use manufacturer-certified lamps.
