Those heads are probably just as durable as the rest of the stuff Victor sells (which, from what I understand, is quite so). However, they will not have the output of the KX2C head (I have not tested this unit, nor do I know anyone who has, but based on the other LED module that they sell, the 220 lumens is "emitter lumens" and not OTF lumens unless otherwise noted.) nor the beam-pattern (expect a smaller, but slightly "hotter" central hot-spot with a more defined spill than the KX2C. I am guessing throw will be similar, but with the TNVC unit having a more narrow beam at distance and a more "defined" spill up close. Again, THAT is just pure speculation based off my ownership of their TNVC 6P module). They are a good buy for 2/3 the price of a used KX2C head though, considering used KX2C heads are...well, kinda something just talked about. If you don't want to spend the $135, I would give the TNVC a good look.
