The Optoma ZK521ST-B is a short-throw DLP laser projector built for golf simulators and always-on installations. It puts out 5,000 lumens at 4K UHD resolution and throws a large image from close to the screen, so players don't cast shadows on the impact area. The DuraCore laser source is rated for 30,000 hours with no lamp changes, which sets it apart from lamp-based rivals that need bulbs and dim over time. It suits home and commercial golf bays, sim lounges and bright rooms where a dim home-theater projector would wash out.
