Need to replace a fan (or both) in an LED fixture. I've searched online a little only to realize I can't locate an exact replacement. So now I need to know how to measure these damn things to size up a compatible replacement. I expect I need to match the hole pattern for mounting purposes, but how do I figure the rest of the details I need to match? What mm fan is this? Measure the blade? It is one of two fans which cool this little off brand 300LED. It's a loaner so I plan to repair it.
