4. Key Features
1) Smart brightness control: memorizing the brightness in use, its light-up brightness can be set, otherwise is the same as last time.
2) Aluminum alloy frame: decrease light decay and color decay; sturdy and durable.
3) Smart energy saving: if the light is on, but no operation, the light will close automatically after an hour to save power.
4) Standard mode: our film viewer can be set standard mode. It is unique for this technology. Users can set the brightness as needed for the standard one. When the viewer is in any other brightness, just need to press the recovery key, it can get back to standard mode. 
5) Separated control: each section can light up and dimming separately, every section can work as a single viewer. The boundaries between each section are clear, no affect with each other, avoid string light affecting the viewing quality. This is our patented technology.
