Can you dim a constant current LED driver?
Although both constant-current and constant-voltage drivers can be made with a dimming feature, not all LEDs are dimmable and the ones that are capable of dimming must be used with the proper dimming technology (e.g., PWM or CCR).

What size LED driver do I need?
We recommend choosing a driver with a wattage capability at least 10% higher than the wattage the LED tape requires to ensure a longer lifespan. For example, 5m of 6w LED tape requires 30 watts. We would recommend using a driver with an output capability of 33 watts or more to power this tape.
What is the difference between an LED driver and a transformer?
LED drivers and electronic transformers for retrofit LED lighting are not interchangeable. They differ in output and load compatibility i.e. which LED lights they will work with. The fundamental difference between the two is that LED drivers output DC while electronic halogen transformers output 12VAC.
How do constant current LED drivers work?
A constant current LED driver is an LED power supply that regulates the current flowing through an LED array so as to maintain a desired level of light output. It provides accurate output current control regardless of the supply-voltage fluctuations and the changes in other operating conditions.
How long do LED drivers last?
Namely, the life of the driving circuit expires prior to when the LED stops emitting light or has its brightness dropped. The typical nominal lifetime of these elements is often times less than 25,000 hours, while the lifetime of LED itself could be as long as 000 hours.
How do I choose an LED driver?
First, consider the voltage requirements of your light. If your LED requires 12 volts to operate, use a 12-volt driver; if it uses 24 volts, use a 24-volt driver, etc. When choosing a driver for a constant-current LED, you must also consider the LED’s current output, which is measured in amps or milliamps.

How do you brighten an LED?
Turn on the power supply. Slowly, turn up the power supply to 100 volts. Look at the LED string as you turn up your power supply’s voltage level. Stop increasing the voltage when you notice that the lights do not shine any brighter for an increase in voltage.
