Package: sufficient enough to keep it undamaged during shipping. Build quality: Black painted metal makes it looks cheap and feels like plastic, or is it a plastic? Let see after some endurance test later. Fan speed: I think the fan speed is dynamic controlled by the small box(driver). After driving for an hour, the fan speed is heard faster than when in bench testing. Lights Output: It must be real CSP Led, I compare it with Cree Xhp50.2, this product is much brighter than cree. Cutout is good, intensity and density is also good. Overall: good price for value. Pending: stability/endurance test and warranty (hopefully doesn't need any).
