There are many imitation lamps sold in the market. They are sold as “Optoma” products with the same model numbers and names, and they look similar to genuine Optoma products. However, these imitation lamps have not gone through the proper quality assurance procedures, and may not meet the quality and safety standards that are necessary for Optoma projector operation. We are concerned that the use of these imitation lamps may lead to early lamp failure, insufficient brightness, and possibly even bursting of the lamp itself. In addition, please understand that Optoma would not be able to provide warranty protection or take responsibility if a problem or accident should occur as a result of using a non-genuine Optoma lamp.
