Voltage drop when using LED Strip lights

Voltage drop when using LED strip lights.  

12 or 24 volt constant voltage DC LED strip lights will always gradually drop in voltage as the current travels along through the length of the strip – this can result in having one end of your LED strip brighter than the other end. 

To avoid voltage drop, firstly ensure that you have chosen the correct 12 or 24 volt power supply for your installation and check that you are not trying to run the LED strip for longer than the advised run length - Lumiled constant voltage LED strip range will run for a maximum of 5 metres.   

Sometimes, having a cable tail attached that is too long can cause voltage drop – remember the power has got to travel through the cable before it even feeds the LED strip so you do not want to have your power supply installed too far away.  

If you need a longer cable tail, you will need to use a thicker cable to avoid voltage drop. Cable thickness is the single most significant factor affecting voltage drop.  

The answer we have all been waiting for! 

The good news is, if you have a large domestic or commercial area that you want to illuminate using LED strip, we suggest using a constant current variant - product code  -  LSP24-120. 

Constant current led strip is designed and based on a constant voltage led strip circuit, however, a constant current IC chip is added to each group of led circuits which automatically adjusts the voltage requirements of the LED in order to operate at the rated voltage. The brightness from start to finish stays the same - saving the need for extra power supplies mid-way or powering from end to end. 

Our IC integrated circuit LED strip will run comfortably for up to 20 metres, powered from one end using the correct size 24 volt driver/power supply.
