This is a commercial projector used primarily for slide shows at special events such as weddings. It was used at most 6 hours a month for the year it was in operation, so the lamp time on it is very very low less than 1% of the advertised lamp life has been used. Works very well, was able to get crisp and clear images out of it with 13ft diagonal from about 20 ft from the projection surface. Quite heavy duty and high quality, sure it would be great for another venue, lecture hall or projection mapping!
