When purchasing LED lighting, read the warranties carefully. Most warranties do not cover when an LED fixture does not meet its advertised performance, leaving you in the dark, light-wise and warranty-wise. Unlike most, Flex Lighting Solutions provides a true and transparent 5-year lumen maintenance warranty.
Now as LED lighting is becoming a mature technology, time has proven sheet metal is a bad choice for most parts of an LED fixture. Always look for LED High Bays made with aluminum heatsinks. They are the most dependable, deliver higher performance and enable a longer LED life thanks to their superior heat dissipation.
Many LED fixture manufacturers contradict themselves by enthusiastically explaining how their drivers have a built-in surge suppression but then later recommend an additional surge protection. So, do you really need it?
