How to manage Epson Projector Lamp
Epson has managed to balance light output, contrast, and resolution without really compromising any of the 3, and the result is a fantastic picture. Whether used for movies, PowerPoint, interactive sessions, or long distance teaching the contrast makes everything discernable with a ratio of 2000:1. The lumens output of 3200 ANSI is bright enough to handle minor amounts of ambient light such as desk lamps or lighting towards the back of the room. The brightness is controlled by the user and the projector can run in a normal mode as well as eco-mode, which saves lamp life. The 230W projector bulb on the inside can be manipulated to provide two different light outputs, however, in my opinion it is always best to go with the normal setting since fluctuations in voltage can also affect lamp life.
The Throw distance starts at 5 feet and can go as far back as 28 feet, however, I believe most classrooms are choosing to place their projectors closer to the screen itself to prevent any interference. It has Digital Keystone correction (both horizontal and vertical), so you should be able to clear up any malformation depending on where you place the machine.
The Powerlite 915W has amazing native resolution of 1280x800p set to an aspect ratio of 16:10. This is definitely a nod to the new wide screen style computer monitors which are WXGA and this should make set up much easier. It comes with all inputs including HDMI and Epson also decided to throw in Wireless Networking using Crestron RoomviewTM. This option allows users to control the projector from any computer by logging into a terminal. Teachers are sometimes too busy to deal with the problems of having to learn the ins and outs of new technology, and this lets the IT people at the school deal with it from a central location.
Color and white light output:-
With Epson projectors, your presentations are sure to shine bright. The Epson EX30 delivers 2200 lumens, whether you’re projecting images with deep, dark colors or a white screen with minimal text or graphics. You get consistent light output, whatever you’re projecting. And, with Epson, you can be confident you’re getting exactly what you need because Epson measures white light output according to the ISO 21118 standard, a more rigid standard than the maximum or outdated ANSI lumens rating used by competitive products.
