You just have to start low and slowly raise the intensity. That light looks fine to me, its essentially the same thing as the taotronics that were mentioned earlier but with a different label. They're all Chinese fixtures.
Edit: you can use a PAR meter if you have one. But I just do what I said above. Work your way up to where everything is happy and growing well and nothing is bleaching.
Bleaching = too much light
Browning = not enough light
