Does it give a wider beam pattern than you'd get with the more usual
grid of chips pointing downwards?

I'd say *considerably* better than downward firing LEDs, the diffusion
sheet (a bit like a circular halftone screen) does an excellent job.

Mine's 6" diameter, 6 watt, mounted centrally in a 6'x4' ish porch with
6'6" ceiling.

It gives a good wash of light onto all walls and the floor, except for
about a 2" band around the top of the walls due to the 3mm high bezel,
so at least a 175° beam.
