Let's talk about the quality... I have seen worse, but the quality control here is far from good. Reflective surface on one of the reflectors is really bad and has no mirror finish to it which automatically drops the light output. The reflective surface is chemically etched to a plastic form and is extremely thin and not durable. Soldering is absolutely horrible and the thermal paste under the emitting chip is not good quality. There is no thermal control and the lens modules after 20 min of working get really hot which means short lifetime. Led controllers boxes are not weather sealed and they also get hot during work. Leftovers from the casting is all over the base and they should to be filed down in order to properly mount the mounting brackets. There is some kind of oxidation/corrosion on the base. I guess for 100$ you get what you pay for.
Another bonus is strong radio interference so forget the car radio :)
Incredible output. Great product. I would have liked them to be 4300K. I'm on miniH1s, and changed them for this led projector , with a great result. In the photos you will find Led projector next to the miniH1. Shrouds should be for 3 inch projectors.
