Faulty LED spotlight before it has even been lit, how is that possible?

COB LEDs are becoming increasingly 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 job site, for fixed workshops there are ESD floors or ESD mats to place on a workbench.
• Hotwiring, never connect a led to an energised led driver, always cover the fuse even for 48Vdc rails, never click the luminaire into the rail when the rail is energised.
  A led driver that is live without a load connected to it does not know what to do, some led drivers can deliver over 100V, if an led with a forward voltage of 20V is then connected to it, at worst the led gets more than 5 times the voltage.
• Heat, a led needs cooling, always respect the manufacturer's specified clearance around the spotlight, the max temp. for a led is usually 100°, above this the Phosphor will start boiling, resulting in a faulty led.

All this can be reviewed in the 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're with us, or when you place an order, we'll stick them on delivery.
