Go to the Halo (Cooper Electric) website and check out the datasheets
for their trim. Some of them will have diagrams showing the light
patterns for a given bulb and trim. Generally it depends on:

Size of can: The larger the can the higher wattage bulb you can use
and the more options you have for bulb type and wattage.

Bulb type (size/shape, flood or spot)

Wattage

Trim kit used.

Type of lighting wanted (general, accent, spot, etc.)
