What it means:

Residential properties have their own rules

 

If your fixture doesn't meet the rule, a 60 watt bulb or a 13 watt  compact fluorescent gets you off the hook, or a motion detector and a 75 watt bulb or 18 watt compact fluorescent will also.

 

The no-light-above-horizontal requirement — “fully-shielded”:  The lamp should be set up into the top of the fixture, or the fixture should be under an overhang that comes down as far as  than the fixture.  Diffused” means covered by, say, frosted glass.  Some illustrations are on a later page.

 

Floodlights

The best floodlight is one on a motion detector.  It gives real security because it detects something moving around the house.
