Singapore- Frankfurt, 10th April 2010

Who invented the term warranty? In my early days in lighting we used to talk about guarantee, not warranty… a warranty seems to be a guarantee with a lot of small print…….  🙂

I am on my way to Frankfurt, but just before I left I had one of the LED suppliers in my office to demonstrate some of his latest T5 LED direct replacements and we got into a discussion about lifespan and warranty. The issue of warranty is becoming more and more a key element in the sales pitches of suppliers and manufacturers as the professed long life of LED would make a longer warranty logical. Yet there are still many suppliers that only give a one year warranty on LED, some painfully agree to a two year warranty. The ones that provide 3 years or more are only the reputable manufacturers and still they do it with conditions attached.

I can understand the conditions, because providing a 3 year warranty is really depending on the frequency of use. An LED installation can be used only a few hours a day or 24 hours a day…that is a big difference. A year at 24 hours a day is about 8700 hrs/ year, so with some manufactures claiming only 15,000 hours for some of their LED systems, a three year warranty may pose a little problem… just for argument sake. But it is at the same time understandable that the market is expecting longer warranty times if the professed longer lifespan of LED’s is such a big part of the sales pitch.

Then there is also the compatibility issue of the components. To extend the warranty the manufacturer/ supplier must be confident that all components are compatible, with tested and certified performances. Too often local manufacturers have doctored a system together from different brand components which may have individual reliability but not necessarily combined in a newly manufactured environment. Insisting in complete brand system configuration is at times necessary to assure its long term warranty.
