Projector Lamps USA is a great partner for helping with our legacy projector maintenance. We lean on them frequently to assist in determining the correct replacement piece for a variety of equipment age and capability. They always have plenty of stock ready to ship, and get it to us in less than a week, even without electing for expedited service. Quality is top notch and they offer a nice selection of entry level and upgraded options for most models. There are several lap suppliers that may seem similar, but these folks have proven to be the best. Thank you for the great service!
