LED Driver 700mA Constant Current Sources for LED

LED Driver 700mA

LED Driver 700mA – Constant Current Source for Power-LEDs

We offer affordable LED constant current sources of high quality. In this product category you can find a compilation of LED operating devices that have a fixed or programmable constant current of 700mA to operate Power-LEDs for example.



  • Alternative with fixed setting for only 700mA.
  • LED drivers with fixed values (350mA, 500mA, 600mA, 700mA, 900mA, 1050mA and more) programmable via DIP switch are available to an inexpensive price here.
  • Different performance classes (15W to 50W).
  • Optionally dimmable via 1..10V, DALI or button operation.
  • We are happy to assist you in choosing your 700mA LED driver.

Why LED ballast with 700mA constant current?

In the early beginnings of LED, low power LEDs were used. 10mA constant current was normal for one LED. This was mostly realized by using a dropping resistor of approximately 270 ohm for the operation on 5V. At a forward bias of approximately 2.5V the remaining 2.5V of the dropping resistor would drop at a current of ca. 10mA.

In approx. 2009 the power of 1W could be turned into light by using so called Power-LEDs with a current of 350mA. The constant current control with dropping resistor would have become true heaters. Accordingly the constant current was used in modern LED drivers with the help of clocked regulators via pulse width modulation (PWM).

The operation with 350mA was standard.

Today with more and more efficient LEDs it’s not a problem any longer. Even currents of >1A with appropriate heat dissipation bring an outstanding price-performance ratio. As a good compromise LED drivers are often set to 700mA. This is roughly an output of 2.5W per LED.

The impact of the current intensity to the LED

 Small currents for a LED mean:

  • Low heating
  • Long durability
  • High luminous efficacy
  • possibly worse cost-benefit-ratio

Doubling the current intensity with LED driver 700mA

  • Higher operating temperature of the LED due to doubling of the intern difference in
    temperature (RthJC)
  • Therefore lower durability (per 10K – bisection of lifetime)
  • Less LEDs for the same amount of light --> lower costs, lower effort to manufacture

Meanwhile, more and more LED drivers are used with 700mA, since the LED technology has improved dramatically in recent years.

LED driver 700mA are now widespread. That’s why you can find a selection in the above mentioned LED drivers which can be set to 700mA via DIP switch.
