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.

Replacement Lamp Sanyo PLC-XU73 Projector
Sanyo PLC-XU73 is a great presentation projector with a bright picture. It is compatible for office use such as a short focus lens, however it may not be as useful for the home theatre enthusiast. The lumens rating is very high and can really make most projectors appear dull in most light settings. The key to its brightness is its 200W projector lamp which is strong enough yet still energy efficient and will last roughly 2000 hrs.

Projector prices have dropped a lot in the last few years. But the cost of replacement lamps has not followed suit. However some lamps are now below $300, most are in the $350 to $400 range and will continue to be for the foreseeable future. Therefore more and more clients buying entry level projectors are shocked to discover that replacement lamps can cost as much as half of the projector’s original price. Projectors are not like televisions that can run without any maintenance. They need to have their lamps changed on occasion, and most have air filters that need to be cleaned every month or two. Certainly longer lamp life can mean lower cost of ownership.
For those thinking of buying a used projector to save money, a bit of caution is warranted. There is usually no warranty on a used projector, and the lamp is likely to be almost expired unless the seller specifically guarantees you a new lamp
Projectors are not maintenance-free. But as long as you are aware that replacement lamps are not cheap and you will need one on occasion, you can usually budget for them over the life of your projector without it having any serious unexpected impact on your finances.
