This 12,500 Lumen SXGA+ large venue projector has 11,083 projector hours and 571 lamp hours. Please note that it does not come with a power supply.

To use this projector, you'll need to connect your own power supply. First, find a suitable location for the projector in a large venue. Then, connect your media source to the projector. When starting it up, give it a few minutes to warm up. Be aware that since it doesn't have a power supply, you need to ensure your external power supply is compatible. For maintenance, keep the projector in a clean and dry place. Regularly check the lamp hours, and when it reaches a high number, consider replacing the lamp to maintain good projection quality. Also, make sure to clean the projector's air vents occasionally to prevent overheating.
