Genuine Osram Bare Lamp Compatible with Optoma DS311 Projector
This item does not include the required lamp module/housing. You must reuse your existing module. If you are not comfortable changing the bulb you must purchase the complete lamp module which is the module with the bulb already installed.
Check below for other lamp options for your projector. We highly recommend lamp modules with Philips, Osram, Ushio and Phoenix OEM bulbs inside for the best lifespan and brightness.
30-Day Money-Back Guarantee. Free warranty replacement 180 days from the date of purchase.
