This glass lens is etched to create an even diffusion.

Its effect is similar to the COSL but the diffusion effect is more pronounced, creating a wider beam with very diffuse edges and nearly obscuring the beam's hot spot.

It reduces the center beam brightness by about 46%.

This lens can be used whenever a highly diffuse light source is needed, especially useful when lighting certain plant material or surfaces where hot spots would be problematic.
