More About Shielding
If you can see the bulb from the side, the fixture is not fully-shielded. The shield should completely cover the bulb target light to only where it is needed.
Ceiling-mounted, recessed, or "can lights" and lights completely hidden by eaves do not require shielding. Pathway lights that do not exceed 12 lumens do not need to be shielded. 2-3 watt led bulbs with warm color (2700K) work well for pathways.
