When Should I Change My Lights? Signs to Look Out For

How many times have you walked or driven past a building with failed lights on the outside? Chances are, when the lights were first installed, it looked amazing, but it’s probably long overdue a refit. Here are four key signs that you need to get your lighting installation updated by professionals. 


Sooner or (hopefully) later, all lights will fail. Sometimes, depending on the installation – it might not be that noticeable that a few fixtures have failed, but quite often there will be gaps in the lighting scheme or specific details which won’t be illuminated. 

With colour mixing LED fixtures, a single channel could fail, which would leave your lights in the wrong colour – imagine a situation where green and red channels are being mixed together to create amber, but the red channel fails on one fixture so one of the lights is green instead.

Energy Efficiency

This isn’t really an obvious sign that your lights need changing, but it is still an important one. If your lighting scheme is still using halogen, metal halide or other traditional lamp types, it will be far less energy efficient than a functional LED scheme. Some businesses can be put off from upgrading to an LED scheme, but the initial output will be offset by the savings provided by using more energy-efficient lighting. 

Light Output Dropping

Over time, all types of lighting drop in output; the lifetime of an LED fixture is usually measured to when the light output is at 70% of what it was when it was initially installed. Over a longer period of time, the light output of the fixture will change, so what was once an eye-catching vibrant installation will eventually look quite faded and dull. 

Colour Shift

Subtle variations in the colours can be obvious, and this is something that will happen to lights over time – particularly to those lights that are driven hard or that use lower quality components. When the light output of a fixture changes over time, the red, green and blue portions will not necessarily drop at the same rate. If the ratio between two colours, say red and blue, changes over time, mixing those colours together will have different results.
