JPEG, PNG and BMP.
11.  How long will the LED light source in the Qumi last and can it be replac\
ed?
The Qumi does not use a typical UHP lamp. It uses a set of Light Emitting Diodes 
(LED) to illuminate and project images. LED’s have a greater lifespan than 
conventional lamps. Qumi LED’s are estimated to last for approximately 30,000 
hours. The lifespan of the LED depends on factors such as brightness, usage, 
environmental conditions. LED brightness can decrease over time.  The LED module 
is not replaceable.
12.  Why do I need to re-adjust the focus on my Qumi after it’s powered up?
For the best picture quality, adjustment of the focus ring may be necessary once the 
operational temperature has been met.
