- Lamp modules supplied by Optoma or our authorized distributors hereafter known as “Optoma genuine lamp modules” are designed and tested to work specifically with your Optoma projector. Whilst copy lamp modules may carry original manufacturer’s bulbs, Optoma specifically screens all its lamp modules to ensure the highest quality and longevity.- Lamp modules are made up of two parts – the bulb and the bulb holder. Optoma genuine lamp modules are designed specifically and uniquely for Optoma projectors. Copy lamp holders may contain differences that could affect the performance of your projector.- Installing a non-Optoma genuine lamp module in an Optoma projector may void your projector's warranty. Repairs resulting from damage done by a copy lamp module may not be covered under your Optoma warranty.- Copy lamp modules may lead to reduced performance and reduced life expectancy.
