Hybrid Light Engine
Casio is definitely a leader in solid state light engines. They’ve been offering an extensive line-up for several years. We reviewed their first series about five years ago. Casio claims to have the largest market share in terms of serious solid state projectors (excluding all those tiny pico and pocket projectors).
The light engines Casio uses are “hybrids” where they use both a blue laser and a red LED, and use phosphors excited by the blue laser to produce the blue and green primary colors along with the LED’s output for the red primary color.
The XJ-F210WN is the one of very few feature-rich business/education projectors we have seen in this price range that offers a hybrid light engine with reasonably high light output. Laser/LED light sources have the advantage of being much more stable over time, in terms of light output and color characteristics, than do traditional lamps.

The laser/LED hybrid light engine discussed above is a major factor in reduced maintenance costs. The up to 20,000 hour expected life of the XJ-F210WN’s hybrid light engine is 4 to 6 times longer than the life of a typical projector lamp. That means significant savings over the life of the projector by avoiding the cost of the replacement lamps and also the labor required to replace those lamps. Also, this model does not have an air filter that requires periodic cleaning or replacement, so that is an additional factor that contributes to the very low maintenance requirements for this model.
The XJ-F210WN comes ready for connection to a wired (Ethernet) local area network with its rear panel RJ45 connector. Casio's available YW-40 Wi-Fi adapter plugs into the projector's rear panel USB connector for enabling wireless networking. Content from PC's can be displayed via wired or wireless LAN connections and with the available Casio wireless adapter installed, content from mobile devices can be displayed. Casio offers the "C-Assist" app for Android or iOS mobile devices which allows for projection of images from smart devices.
The files for a presentation can be either transferred into the projector's internal memory or stored on a USB flash drive plugged into the projector's USB port. I would note that while some business projectors have the ability to directly read and display standard Microsoft Office files, Casio requires Powerpoint files be converted, using an available software program called "EZ-Converter FA", into a file format that is compatible with the projector's file viewer function. While this is less convenient that being able to read Powerpoint files directly, it does work. A number of other common file formats including photos in jpg, bmp, png and gif file formats can be directly displayed without the need for external conversion. Also documents in pdf format can be directly displayed as can videos in avi, mov and mp4 file formats.
In addition, when the wireless adapter is installed on the projector, presentations can be made from a mobile device using the wireless network connection.
Quick Power On/Off
The use of a hybrid light engine allows for a quick startup of the projector with full brightness being achieved in as few as five seconds, and the time from startup to screen display is shortened dramatically as compare to traditional lamp-based projectors. Also, no lengthy cooling down period is necessary when the power is turned OFF.
