Parking lot lighting commonly refers to outdoor lamps, that usually sit on poles above parking lots, pavements and driveways. This exterior lighting intends to mostly explain areas where cars and pedestrians move. It matters to protect folks and help them reach their target, when the sun sets.
The shoebox lamp is one of the designs, that you find everywhere. The name fully answers, because it really looks like a shoebox standing up on a pole. Its flat and rectangular form hides all parts in a compact, efficient mode.
Simple Guide to Parking Lot Lights
One uses them to light big spaces, as parking lots for many cars streets and public gathering spots.
LED lights for parking lots became a real revolution lately. They give stronger light, while they consume much less energy, what easily lowers your cost for electricity. Options for color temperature dump the old methods from usage.
Some LED lamps can replace the task of traditional 1000-watt HPS bulbs. One manager of services, that I know, altered those old 1000-watt HPS units to 144-watt LEDs. Within three years, that lowered his monthly bill from almost 391 dollars to 295 dollars.
Here the kdin of savings, that adds up quickly.
Pole lamps set themselves directly to high poles and posts. Commercial pole systems allow to choose the power and the height from 10 to 30 feet. If you work with a 28-foot pole, the distance between lamps usually ranges between 80 and 130 feet.
At shorter 80-foot intervals, a 200-watt LED provides lots of light strength.
Footcandles help to measure the lighting of parking lots. One footcandle describes the light, that one candle gives at one foot of distance. When you plan that, well control the needs for footcandles and also consider the spread of light.
Beside hotels, choose type II, III or IV for light spread with shields on the lamps, to lower the surrounding light and stop light from entering threw windows and doors. Full cutoff or down-facing design works well, they stop light from going upward, where it does not need to.
Darkness leaves areas in shadow and opens way to danger. Good lighting does the opposite, it strengthens security and limits risks for all. LED lamps spread clear, precise and even light through the whole space.
Dark shades and surrounding glow disappear, what pushes the place safer for folks, that walk here.
Solar lighting solutions answer for parking lots also. Full solar systems with batteries and panels avoid digging for cables and do not raise your power cost. Some solar parking lots operate well during years.
Another saving option is retrofit LED corn-cob bulbs, they cost less than replacing whole lamps andinstall in little time.
