The Infocus LP650 was one of the first projectors to use the technologically advanced 250 watt projector lamp. The alternate current projector lamp operates at a higher wattage than any projector lamp before it and therefore can produce a brighter image.

Many users give evidence to the amazing clarity and brightness of the Infocus LP650 even when operating the projector in well-lit or daylight flooded rooms.

Overall, the Infocus LP650 projector and projector lamp deliver. While there may be some small complaints about the unit malfunctioning or freezing up, most of these are because the unit is overheating due to lack of maintenance and care. Infocus will certainly retain their market share with phenomenal products like the LP650.
