The Colorlight SSR-L16 brightness sensor measures ambient light for LED display brightness control. Connected to a compatible Colorlight iM9 multifunction card, it supplies light readings so the display can follow a brightness adjustment strategy configured in the control system. This helps maintain comfortable viewing as daylight changes and can reduce unnecessary screen brightness.
Key features
- Ambient-light measurement: 0–65,535 lux measuring range.
- iM9 connection: designed for the Colorlight iM9 multifunction card, which offers four optional expansion ports.
- Outdoor use: waterproof, dustproof and salt-resistant construction described in the Colorlight specification.
- Installation: standard 5 m cable can be extended; sensor body measures Ø32 × 41 mm.
- Power: rated at 5 V and does not need a separate external power supply when connected as specified.
