6. How long will the LED light source in the Qumi last and can it be replaced?
The Qumi does not use a typical Qumi 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.
7. 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.
