Ask Your Electrician/Electrical Supplier
Ask your electrician or local electrical suppliers for full-cut off or fully shielded light fixtures and select those which are compatible with your architecture and community.
If you wish to go further, contact the manufacturer's representative to see a sample of the fixture(s) and ask for a free lighting plan. Most lighting manufacturers have Application Departments which will execute free lighting plans to meet local lighting codes.
