In addition to size, the height of the fixture is another important consideration. As a general rule of thumb, outdoor entryway lights should be positioned at eye level. More specifically, the center of the light source should measure 5.5 to 6.0 feet from the ground. Fixtures also should be mounted 8-10 feet apart.
Subsequently, one may also ask, do you need special light bulbs for outside?
Halogen spotlights & flood light bulbs: These light bulbs may be used indoors or outdoors. LED Lights: Light Emitting Diode or LED bulbs may be used indoors or outside. Compact Fluorescent light bulbs: Some CFLs may be used outdoors, but you should be sure to check the maximum temperature the bulb can withstand.
How many lumens should an outside light be?
That said, our professional suggestion on lumens for various outdoor lights includes: Path lighting:100-200 lumens. Step lights: 12-100 lumens. Flood lights: 700-1300 lumens.
How many watts do I need to light up a room?
So if you have an 18' long room x 12' wide room multiply times 1.5 = 324 watts, that's how much wattage is needed to adequately light the room. You can divide that lighting into more than one source. 2 Lamps @ 150 watts each and 1 lamp @ 60 watt would be more than adequate light for the room.
