QPT-238 is an LED short distance projector for both home and office use. It can project up to a 40” screen at a 1 m distance, so a big screen can be enjoyed no matter how small the available space is. The screen protector cap is integrated into the machine so that cap loss is no longer a worry. Using the mercury-free, high lighting efficiency LED, its light bulb’s life expectancy is 6-10 times longer than that of a traditional light source. This not only greatly reduces cost thanks to a decrease in frequency of light bulb change, it’s also more environmentally friendly.
