Back up one level on that link and there are lots of LED high-bay lights. Stay with ones that are less than 300 watts, and it seems like most of them don't require fans.

Seems like there are a lot of options without fans, using big heat sinks. Seen them for around $100-200 on Alibaba. Elsewhere they are harder to find.

    Are there not already LED products available for replacing these
    type of lights?  You just like tinkering, and want to reinvent
    the wheel, huh?

            Progress is slow, but am making progress.  This array is
            designed to replace all my 1000 watt metal halide high
            bay lights.  It burns 330 watts. Trying to eliminate fans
            etc. If was was going to use fans I would have been done
            by now. But no fan is going to last 20 years.
