4 adjustable red LED arrays
Built-in strobe controller
3 year limited warranty

This light has four arrays of LEDs, each with a 4” by 1” window. It is typically mounted just above objects in a dark-field configuration, where the low-angle light will accentuate edges and surface features. However, it can also be mounted further from objects for bright-field applications. The angle of each light array can be easily adjusted from 0 to 90 degrees to achieve optimal performance.

This light features a built-in strobe controller, and may be connected directly to 24 VDC power. A 4-meter cable is included.

Please contact us if you're interested in a different diffuser material, or a longer cable.
