One other thing that might be considered: how long of a service life will any LED fixture have? Not just the LED emitters themselves but the power supply, driver board, fans (if used). Which manufacturer will be able to supply repair parts and for how long after the sale? Some manufacturers excel at parts and service, others not so much. Once the product is discontinued, can you get any parts?
We are used to 40+ years of service from incandescent fixtures. They just keep going with only lamps and a socket replacement. Just a thought.
