C-more 8", 10", 12", and 15" units have field replaceable backlight bulbs to help preserve your investment. The original backlight bulbs and replacement bulbs on all C-more panels are rated at 50,000 hours. That's almost 6 years of continuous operation. Turn on the "screen saver" feature to extend the bulb life even further, or use the Event Manager to dim the backlight settings at predetermined times, or whenever the machinery is idle (based on a PLC tag).
