Hello,

Does anyone have a diagram that shows the different sizes of reflectors and the coverage they give out? I've been looking everywhere for one.

Thanks

Not exactly. However, the chart linked below will show what the spread will be at varying degree spreads. This chart is for 7" reflectors and grids. To calculate a specific spread for a specific size reflector, use the measurement for 7" reflectors, then add the difference in reflector size to the end spread.

For example, 7" reflector with a 30 degree spread at 10 feet will illuminate a circle of about 72 inches. The 18 OMNI is 18 inches in diameter, or 11 inches more than the 7" reflector. This will result in a circle of about 83 inches in diameter.

Also, remember beam spread is measured from centerline out to -1f. Beyond that, you can have various rates of fall off, from gentle to almost spotlight-like hardness. The beam spread measurements do no describe the fall off pattern.
