Buying LED Flood Lights | What You Need To Know

Definitions

Lumens &#; Lumens measures the total amount of light emitted per unit of time. This unit essentially measures the brightness of the light.

Wattage &#; Wattage refers to the amount of power a light projects. Generally speaking, higher wattage lights will project more lumens (brightness). LED flood lights come in a wide range of wattages. This ranges from 15 watts all the way up to 400 watts.

Color Temperature (Kelvin) &#; Kevin or color temperature basically corresponds to the color of the light projected which also correlates to heat. LED flood lights generally come in two different measurements: K, and K.

DLC Listed &#; DLC stands for Design Light Consortium and certifies that the product can perform under high levels of energy efficiency.

Photocell &#; A photocell uses a sensor to detect the level of lighting available outside and turn on if necessary. In other words, once it becomes dark, the light will turn on. Certain LED flood lights are photocell compatible and can serve as &#;dusk to dawn lights.&#;

Base &#; The base for a flood light involves the type of mount to attach the fixture. For example, some mounting options such as a Trunnion Mount allows the flood light to cast illumination from side-to-side. Other mounting options such as a Slip Fitter Mount involve mounting the light up on a pole.

Lens &#; The type of lens a lighting fixture uses will influence how light is dissipated. Two common types are a clear lens or frosted lens.

Voltage &#; Voltage involves the amount of work required per unit of charge to move a test charge between two points. For LED lighting, this is the amount of power a lighting fixture provides a bulb.

Shorting Caps &#; The Shorting Cap contains a shorting connection between the line and load of the receptacle keeping the lights on at all times when power is being supplied.

Motion Sensors &#; Motion sensors inside outdoor lighting fixtures detect when there&#;s movement close to the light and will automatically turn on. This is an ideal for security lighting purposes.

Dusk to Dawn Lights &#; Dusk to dawn lights are any light which automatically turns on once the sun begins to set. Certain LED flood lights can be installed with a photocell and serve as dusk to dawn lights. It&#;s important to check product descriptions and spec sheets to ensure your flood light is photocell compatible if you wish to use this functionality.

Selecting Wattage for LED Flood Lights

Wattage refers to the amount of power a light projects; thus, the amount of watts light bulb has pretty much dictates its brightness. In other words, the higher the wattage, the brighter the light will be. There are a wide range of wattages available for LED flood lights. This ranges from low wattage lights (15-40 watts) all the way up to industrial grade 350+ watt flood lights for major applications such as airports and sports stadium lighting. We&#;ll break this down further below.

Low Wattage (15-40 Watts) &#; Flood lights that are considered &#;low wattage&#; operate with bulbs in the range of around 15 to 40 watts. These are ideal to illuminate small areas such as a footpath or door way. These bulbs generally provide ample illumination for residential purposes or very small areas around commercial buildings.

Mid Wattage (40-80 Watts) &#; Mid wattage lights operate with bulbs in the range of around 40 to 80 watts. These are ideal to illuminate areas such as a small yard, garden, or driveway with a moderate level of brightness.

High Wattages (100 Watts or more) &#; Once you get into triple digit wattage numbers, the bulbs are considered &#;high wattage.&#; These bulbs are necessary for applications such as parking lot lighting, roadways, and other municipal or commercial lighting needs. According to the International DarkSky Association, roadway lighting may have wattages up to 400 watts. These high wattage bulbs are mounted on poles high above the ground.

Ultra High Wattage (400+ Watts) &#; 400+ watt flood lights are the highest number of approved wattages. These are typically only appropriate for major municipal or industrial lighting verticals such as airport lighting, highways, large parking lots, or outdoor sports arenas.

What Lumens To Use

Lumens measures the total amount of light projected per unit of time. In other words, the higher the lumens the brighter the light. It&#;s important to note, this number also correlates with wattage; thus, as the amount of watts go up, so does lumens.

Low Lumens (1,600-4,000) &#; LED Flood Lights operating between 1,600 and 4,000 lumens are ideal for small outdoor area lighting such as a staircase, walk way, etc. These are very common for residential or small commercial needs.

Medium Lumens (4,000-10,000) &#; 4,000 to 10,000 lumens is a mid range of brightness. This level is ideal for yards, fields, and slightly larger exterior areas around buildings.

High Lumens (10,000 and up) &#; High lumens outdoor lights are generally used for municipal areas or larger commercial applications such as parking lots, cities, etc.

Ultra High Lumens (50,000 and up) &#; 50,000 or more lumens is typically only ideal for large industrial needs like highways, airports, and large parking lots.

Wattage Lumens 15W 1,663 30W 3,720 50W 6,180 80W 10,340 100W 13,500 150W 20,250 230W 31,050 300W 40,500 400W 50,200

Color Temperature (Kelvin)

5,000K &#; K LED flood lights are by far the most common. This color temperature projects a cool white illumination that emulates day time environments. This is very ideal for the illumination and security of outdoor spaces.

4,000K &#; 4,000 Kelvin LED bulbs project a natural colored light you commonly find within workspaces.

3,000K &#; 3,000 Kelvin is a warm color of LED light used primarily inside restaurants or houses. It&#;s rare to find outdoor flood lights in K as it&#;s not recommended.

ZHL lighting group have been widely recognized by the industry as the top manufacturer for outdoor floodlights. In this episode, Our team of engineers will explain how to choose the right floodlight product.

If you are a contractor or electrician, it is important for your customers to have the suitable flood lighting installed in their outdoor spaces. Quality floodlight provides additional safety, security and optimum efficiency to a wide range of area lighting applications. Industrial areas, sports facilities, billboards, recreational facilities, ports, parking lots and driving ranges to name a few!

&#;As a contractor it can be daunting to choose &#;Right First Time&#; outdoor floodlights considering heaps of choices out there.&#;

However, as a real professional, you would like to see quality, efficiency and low maintenance professional fittings to keep your clients happy. We would like to share our experience when choosing the Right First Time floodlights. Following these simple 6 steps should help in your buying journey.

&#;Safety standards,
height, angle, glare and
energy efficiency of your
fittings could make a

output for the spot you
want to illuminate.&#;

 

LOCATION. LOCATION. LOCATION.
Like any other type of lighting it is key to determine what kind of facility and area you will be installing floodlights to cover with light. Safety standards, height, angle, glare and energy efficiency of your fittings could make a big difference in final output for the spot you want to illuminate. Make sure to also consider obstacles such as moving trucks, doors, drainage; distance from neighbouring property; and energy consumption in the early stage of your project.

COLOUR TEMPERATURE
Colour temperature is a key specification when you&#;re looking for a specific application. For security, go for cool white ( K) or daylight colour temperature ( K), because it appears brighter to human eyes and more pre-emptive. If you&#;re working and playing under cooler light, it looks more natural and helps you to be more alert and concentrate on the job at hand. If you want to enhance architecture, warm colour temperature ( K) will create a welcoming and cosy feel. You might have observed that effect in many façade and hospitality applications. See the surface and test colour temperatures to enhance the area or architecture.

BRIGHTNESS
Lumens vs Watts War: Lumens equals brightness and watts does not. Not that watts are bad, as they help us with energy use. Floodlights output anything between 2,000-202,000 lumens. Choose lumens depending on the size of the area you want to illuminate. Small residential areas like backyard might use lumens, whereas large commercial areas like car parks might need 20,000+ lumens. Again, height and angles of installation also helps in choosing the right lumens for your floodlight.

POLLUTION
When designing any kind of lighting outdoors, you should always minimise upward light. This is purely wasted energy and contributes to sky glow or light pollution. The good optical control of LEDs means that they deliver the light where it is needed and reduce pollution at the same time.

UPGRADE TO LED FLOODLIGHTS, LED&#;S TALK!
Three major advantages of using LEDs outside are their long life, reduced maintenance and better beam control. This leads to energy and cost savings for your customers. Contrary to most conventional lamps, in well designed fixtures, LEDs do not fail abruptly (or catastrophically). Instead, their light output deteriorates over time. Luminaire life, on the other hand, has to do with the reliability of the components of an LED luminaire as a system, including the electronics, materials, housing, wiring, connectors, seals and so on.

KEY FEATURES AND BENEFITS YOU SHOULD LOOK FOR;

• High Performing Optics that deliver maximum application coverage without being obtrusive.
• Efficient LED Thermal Design Fins on the back of the luminaires can ensure good heat dissipation; these create airflow around the housing to prevent dirt from settling on the luminaire.
• More energy savings for example, system efficacy over 120lm/w generates more than 50% in energy savings compared to conventional floodlights.
• Easy to install for example, factory fitted cables and tool-less opening reduces installation and maintenance time.
• Flexibility in optical beam choices (symmetric wide and, asymmetric medium and wide) will suit most lighting application needs.
• Excellent reliability meaning 15KV/KA surge protection and non-corrosive die-cast aluminium housing and bracket means you can install in harsh environments.
• Long-lasting for example, Lifetime 50,000 hours at L70 means that after 50,000 hours, the LEDs are emitting 70% of their original output.
