How To Determine Brightness Of LED Flood Lights

There are various factors you need to consider when determining the brightness of the LED flood light.

Location plays an important role as it determines how much of the area you need to light up.

If the area is large, you require brighter LED flood lights so that they can illuminate the whole area.

For instance, large stadiums require brighter LED flood lights than private homes.

Also, confirm if you will be intruding on other people’s property as bright light will likely spill over to surrounding areas.

This is vital when you are using the LED flood lights in your private home.

Besides, the brightness level may distort the vision of oncoming traffic if it is near roads.

For this reason, you can angle the light downwards so that you do not distract oncoming drivers.

An electrical performance test will make sure the output is suitable for the application.

Photometric Parameter Test

This test entails measuring the visible light and how humans will perceive the brightness of the light.

The unit of measurement is lumen [lm].

Color Parameter Test

This test will measure if the LED flood light will emit the correct color as per the design specifications.

Quality Certifications And Marks LED Flood Lights Should Have

LED flood lights have to conform to international, national, and regional standards to ensure they are safe for use and work optimally.

Examples of these quality standards entail the following:

CE Mark Of Quality

This standard will ensure LED flood lights comply with EU standards by ensuring they meet health, safety, and environmental considerations.

Besides, complying with this standard enables manufacturers from different countries to sell this light in European Economic Areas.

Restriction Of Hazardous Substances [RoHS]

This standard restricts manufacturers from using hazardous materials when manufacturing LED flood lights.

To date, RoHS bans the use of 10 toxic materials as they pose a danger to people and the environment.

Ingress Protection [IP]

This standard describes the sealing level of LED flood lights against dirt and moisture.

A high IP rating means better sealing.

Underwriters’ Laboratory [UL] certification

This standard ensures the LED flood lights have been tested by UL according to nationally recognized safety and sustainable standards.

ISO Certification

This standard ensures the manufacturing, processing, and documentation meet the necessary quality assurance standards.

Illuminating Engineering Society [IES] standard

This standard entails how the LED flood lights will distribute light from the source by using measurements from real-world data.

Function Of Heat Sink In LED Flood Light

Heatsinks are components that enhance the flow of heat away from the electronic parts of LED flood lights.

They accomplish this by increasing the working surface area of the LED flood light and the quantity of low-temperature fluid moving across it.

The types of heat sink you can find in LED flood lights include:

Active Heat Sinks

This system uses forced air to enhance the flow of fluid across the hot regions of the LED flood light.

For instance, it may use a fan or blower to provide the forced airflow.

The air then flows across the heat sink, increasing the thermal gradient, and allowing heat to exit the LED flood light.

Passive Heat Sinks

These designs depend on natural convection to cool the system.

Here, the buoyancy of hot air will cause air to flow across the system thereby not depend on other power or control sources.

However, they are not as effective as active heat sinks when it comes to transferring heat.

Hybrid Heat Sinks

These heat sinks use both active and passive heat sinks.

Besides, they are not common and rely on control units to cool the LED flood light based on the temperature needs.

As the LED flood light operated at cooler levels, the source of forced air is inactive hence, cooling the light passively.

When the LED flood lights reach higher temperature levels, the active cooling systems become active and enhance the cooling capacity.

How To Choose Best Reflector For LED Flood Light

LED flood lights use two types of reflectors namely, ellipsoidal and parabolic reflectors.

In parabolic reflectors, you will place the LED at the focus point within the parabola-shaped reflectors.

This allows parallel beams of light to reflect off the reflector hence you cannot focus the light since the light does not converge at any point.

Ellipsoidal reflectors can focus the light and operate in tight spots.

How SMD And COB Technology Compare In LED Flood Lights

SMD stands for Surface Mounted Devices while COB stands for Chip On Board.

Here is how these two compare:

COB vs SMD Flood light

SMD vs COB Flood light

Quality Of Light

SMD LED flood lights use several point lights combined to emit a main point light.

COB LED flood lights are surface lights and offer uniform illumination with a large adjustable beam of light.

Besides, it has no glare like SMD LED flood lights.

Productive Process

In SMD LED flood lights, you will conductive glue to make LED chips and use insulating glue to fix the pads of the lamp to the holders.

Once you conduct the performance test, you will cover it with epoxy resin.

COB LED flood lights entail directly fixing the LED chip on the pads with conductive and insulating glue.

Afterward, you will solder after conducting a performance test, then cover with epoxy.


When making SMD LED flood lights, being by mounting the LEDs on the PCB board through reflow soldering.

In COB LED flood lights, reflow soldering and mounting are not necessary since you will directly apply the COB to the lamp.


The manufacturing and labor costs of the lamp beads in SMD LED flood lights are about 15% of the cost of materials.

However, the labor and manufacturing costs of COB LED flood light beads are about 10% of the cost of materials.

This means the cost of manufacturing COB LED flood lights is less than that of SMD LED flood lights.

Color Temperature

COB LED flood lights mostly offer one color temperature while SMD LED flood lights can offer multiple color temperatures.
