This is a quality 2" x 4" backlight manufactured by Spectrum Illumination. It is typically used to image objects in silhouette for measurement applications and feature presence detection. It can also be used as a low-intensity diffuse front light.

The light includes a white diffuser as standard. It may be operated in continuous or strobe mode. If used in continuous mode, the light should be mounted against a metal structure to provide additional heat dissipation.
