How long should your LED Light last?

By February 16, 2015 No Comments

We often hear the words ‘how long should your LED Light last?’ Five years ago at the start of the LED Lighting revolution, LED Lighting was sold as a product that would last for at least 50,000 hours.
The reality was rather different and many of the earlier LED Factory Lighting and LED Flood Lights have already been replaced due to driver failure or substantially reduced light levels. Therefore, does a reduction in light levels [during the warranty period] in excess of 30% [L70] constitute a warranty claim?
When designing our LED Low Bays, LED High Bays and LED Flood Lights, the number one criteria is how to keep the LED and LED Driver at an acceptable temperature. This is the key to supplying an LED product that will perform for in excess of 50,000 hours.
This is achieved by working with our LED supplier, OSRAM Opto Semiconductors who have assisted with our designs to ensure that our range of LED lighting will perform for in excess of 50,000 hours.
BSSLED believe that all LED Lighting manufacturers should clearly state exactly how their LED Luminaire will perform over the expected life span and make clear statements on light output warranty.
Our LED High Bays and LED Flood lights use the OSRAM Oslon Square LED, the predicted performance of this product is to retain over 90% of the original light output over a time scale of 100,000 hours.
Within the overall design of an LED Luminaire, it is widely accepted that the first point of failure is likely to be a component within the LED Driver. Most European Driver manufacturers will work on a design criteria that will allow their drivers to last at least 50,000 at the maximum operating temperature. BSSLED have invested substantial resources into thermal management of our LED Luminaires to ensure the driver can operate at the lowest possible temperature and worked with LED Driver manufacturers who provide built in safety devices that reduce the output load in the event of the maximum case temperatures being reached.
At BSSLED, we will have 100% confidence in our products and should the light level drop below that specified by our LED suppliers, we will treat this as a warranty and replace the LED light Source. Before you chose your LED supplier, ensure that they are prepared to do the same.
BSSLED Limited are a UK manufacturer of LED Low Bays, LED High Bays and LED Flood Lights. All our products have a full 5 year warranty.
