Having a 28W LED lamp with constant current LED driver which has some dip switches where I can change the current, is it safe to lower the current to reduce the brightness of the LED?

  • I'm inclined to say yes. But to make sure there's no hidden caveats, perhaps you could update your post with information about the LED lamp and driver. (make, model, datasheet...) – Unimportant Mar 22 '21 at 19:07
  • the lamp is a Caboche PLUS Grande LED, i can't see what type the LED's are (built into the lamp); the LED driver is a TCI Professionale 42 BI https://win.tcisaronno.com/downloads/?IDnode=3118&field=docs&language=EN .. – Twan Manders Mar 22 '21 at 19:21
  • Datasheet does not have info how to set DIP switch to dedicated current. Check out for additional documents, like manual, installation guide, etc. – user263983 Mar 22 '21 at 19:41

    the dip switch settings are written on the LED driver going from 300 mA (OFF OFF OFF OFF) to 1050 mA (ON ON ON ON) .. with 50 mA intervals – Twan Manders Mar 22 '21 at 19:51

I would think so, yes.

The constant-current driver Professionale 42 BI 127486 states that it will work up to 1050mA output. That is the maximum it can deliver; whether you use all of that or not, is up to you.

As a side benefit, the LEDs will last even longer when under-powered.

However they could, if run dimly enough, appear to color-shift slightly. The only way to know if this will happen would be to try it.
