"With great power comes great responsibility."
A constant current power supply varies the voltage across an electronic circuit allowing the device to maintain a constant electric current. This ensures that, no matter the variation in voltage, the current delivered to the LED light does not change.
Constant voltage drivers have a fixed voltage of IE: 12, 24 or 36 volts DC supplied to the circuit.
So when purchasing a LED driver or power supply how do we decide if we need a constant current or constant voltage LED driver for your application? Choose from our range of Drivers LED SAA Approved suitable for your application.
Constant Current Drivers
For most LED applications, it is better to use constant current drivers as they will ensure all the luminary`s are even in brightness with undefinable change.
They offer you the designer & architect peace of mind your project will look even & professional.
Ideal for home lighting, shops, hotels & displays where consistency & even lighting will be noticed.
Constant current LED drivers are more efficient than constant voltage drivers as far as lumens per watt output.
Constant Voltage Drivers
Many LED projects can be made by stringing or connecting luminaries together such as LED modules in signs or garden LED lighting systems.
If you had 2 lights on one string connected in series then another string running 4 lights in series the constant voltage driver will ensure the 2 light string will not be brighter than the 4 light string providing even lighting on both strings.
One must keep in mind on larger projects there is voltage drop over distance so having 20 lights wired in one long string or series the last LED may not be as bright as the first LED providing uneven lighting. This can be overcome by wiring the 20 lights in parallel or 4 strings of 5 lights for example.
Voltage Amplifiers will also help to provide even lighting in each string.

Even lighting is the key to creating that Zen like feel and finish. Clean smooth lines & minimalist decor adds to a tropical feel.
When selecting the right LED lighting there is a lot to consider. We offer great quality LED Lighting at a factory price.
You can be rest assured we are continually improving LED Lighting with the best available components.
