Faulty LED spotlight before it has even lit up, how is that possible?
We've all experienced it before, there are three common causes which are explained below and in the appendix.

COB LEDs are becoming more and more efficient, recognisable by the yellow LED dot getting smaller and smaller, this also makes them more sensitive.

The three most common causes are:
  • ESD – Electro static Discharge
    Use ESD gloves on a worksite, for fixed workshops there are ESD floors or ESD mats to place on a workbench.
  • Hotwiring, never connect an LED to an energised LED driver, always cover the fuse even for 48Vdc rails, never snap the luminaire into the rail if the rail is energised.
    An led driver that is energised without a load connected to it does not know what to do, some led drivers can supply more than 100V, if an led with a forward voltage of 20V is then connected to it, it will get the led at worst more than 5 times the voltage.
  • Heat, an LED needs cooling, always respect the manufacturer's specified clearance around the spot, the max temp. for an LED is usually 100°, above this the Phosphor will start boiling, resulting in a failed LED.
All this can be reviewed in PDF.


To make the step a little smaller, we already have a free set of ESD gloves available, feel free to ask for them when you are with us, or when you place an order, we will put them on delivery.
