LED fixtures, such as

With energy consumption that is less than half of what 150-watt LED parking lot light that is a direct replacement for 400-watt metal-halide (MH) fixtures. That’s 250 watts less for the same amount of light!

The average price of electricity per kilowatt-hour (kWh) is 12 cents. To figure out the monthly cost of running 25 LED parking lot lights for 11 hours per day, use this formula: (combined wattage x monthly hours of use)/1,000 x price per kWh. For 25 LED lights, (3,750 x 330)/1,000 x .12) the total would be $148.50 per month or $1,782 per year.

When the same formula is used for 400-watt MH fixtures, the monthly cost is $396, and yearly cost would be $4,752. So, in this situation, switching to LED fixtures would save approximately $3,000 per year. When coupled with the savings on maintenance, LED fixtures can save $6,470 per year. At that rate, the cost of 25 $340 LED fixtures would be recouped within two years.

Unlike LED fixtures that light up instantly, HID parking lot lights require a warmup period of up to 10 minutes before they reach full brightness. They also can’t be turned immediately back on after being switched off; this is called restrike time, and it can take up to 15 minutes before they can be turned on again. Attempting to power on the lights before the bulbs have cooled can damage a fixture’s components and cause the HID bulb to fail sooner.

HID lamps consist of a ballast and a quartz tube that contains gas, metal salts, and two tungsten electrodes. In order to create light, an electric arc passes from one electrode to the other through a gas (most commonly mercury, metal halide, or sodium). The mercury used in this process is dangerous if enough is inhaled or released into the environment. If an HID bulb bursts, all contents should be put into a sealed container or sealed bag and taken to a recycling center or hazardous waste facility. If HID fixtures are used indoors, wall packs and canopy lights, are used indoors, the possibility of ultraviolet (UV) radiation exposure should be taken into consideration. HID bulbs emit a substantial amount of UV radiation, but an outer glass envelope prevents the radiation from escaping. However—according to the FDA—”If the outer bulb breaks and the inner tube continues to operate unshielded, intense UV radiation is emitted. UV exposure at this level can cause eye and skin burns, as well as blurred or double vision, headaches, and nausea.” The UV light from an HID bulb with a broken envelope can also lead to discoloration of items and fabric. LEDs emit little to no UV radiation.

In short, LED lights are a better alternative to HID parking lot lights. They offer a great deal in the way of savings, longevity, maintenance reduction, brightness, color, and safety. While it may take a short amount of time to recoup the price of switching to LEDs, all of their qualities make it easy to see why so many businesses have started the process.

When your saying goodbye to guests in the evening, you don’t want to send them out in the dark to fumble their way back to their vehicle. Without proper outdoor lighting your front yard can be riddled with hazards at night. Installing outdoor and landscape lighting can add safety in a number of ways as well as add pleasing aesthetics to your home at night.

Outdoor lighting can add functionality in a number of ways – it can illuminate potential tripping hazards, deter criminals, and add a pleasing look to your home at night. The trick is to have the lights positioned correctly to have the desired effects. When placing your outdoor lighting keep these areas in mind:

Installation of outdoor lighting can be different depending on the type of landscape lighting you choose. If you are using solar powered or battery powered you will not require any additional electrical work. If you are looking to install electrical lamps and fixtures on the outside your home or along a pathway it will require the wire to run underground, because of the high voltage, to the home’s electrical system. If you are unsure of how your new outdoor lighting connects to your home, or want to prepare to install new lighting, have an expert electrician do the installation for you.

Three common sources of outdoor lighting are fluorescent lamps, metal halide, and LED lighting. Fluorescent lamps are designed to run efficiently, but can have trouble starting in certain temperatures. Metal halide are highly efficient within a temperature range, but require approximately a minute to warm up – not ideal for motion lights. LED lighting is a popular choice because they are highly efficient, require no warm up time, and the bulb lasts longest, but this all comes at a higher cost.

Outdoor and landscape lighting is very important and something every homeowner should keep in mind. With so many options out there, it can be difficult to know where to start and what will work.
