Industry leading lifetime is achieved using Optoma’s DuraCore technology. Implementing advanced laser diode cooling techniques and an innovative dust resistant design.
Optoma projectors have been designed to operate 24 hours a day in standard orientation. Perfect for applications where prolonged periods of use is required. Subject to 24 hour terms and conditions.
24/7 Operation – standard lamp warranty applies. Projector warranty is based on standard business usage hours. For optimum performance Optoma recommends that your projector is turned off or placed in standby mode for 30 minutes every 24 hours to prolonging the life of your lamp.
