The Slim Series incorporates a CASIO developed and patent pending Hybrid Light Source which combines Laser and LED technology for amazing high brightness and can last up to 20,000 hours. The Slim is an earth-friendly, low maintenance, 5 pound projector with features such as a 2X Power Zoom Lens making it a great portable projector. The Slim eliminates the need for a short life mercury lamp (typically 3000 hours) and is economical to operate.

The main differences between the models listed below will be the aspect ratio (4:3 vs 16:10) and whether or not it has the USB / Wireless LAN connectivity features.  All projectors come with a 3 Year Warranty and operate at 270W.  They are also mercury free.


Also if you need any replacement bulbs for your current projectors we are offering discounts in the range of 10-25% off bulbs through August 31st.  Discount varies by model.  Please contact us for details.
