On the next run of fixtures, you should make them able to be hung without drilling into the fixture amd voiding the warranty. Maybe something like a nut that is welded to the top of the fixture and all the user would have to do is screw in some supplied eye bolts. Or, something that will slide into where the legs go. If you cam make an affordable dimming fixture, then hanging a fixture isn't that big of a deal.
+1. I figured out a way to hang my 24" Ray 2 without drilling. Pretty easy, but it would also be easy (with the right tools) to make a plastic bracket that would slide in where the legs do. Could even sell it as an extra. I'd pay for it.
