Just got my “new” SF4000, there is a screw missing on one of the drivers, other screw heads are damaged, the aluminum board is arched, the light is clearly used and the box it was delivered in looks like it has been around the world.. I sent a support email to request a replacement or a refund. Here is the latest reply that I received.
“ Really sorry for what happened.
We guess it may be caused during transportation, please don’t worry, we will solve it with you.
We check that the product is shipped from our warehouse and is new.
As you can see from the pictures you sent, the lights are functional.
The dropped screw, we confirmed with the engineer, will not affect the normal use of the lamp, it is to fix the power supply.
In order to express our apology, we can apply for a refund of 20USD to you, you can buy the screw to use, could you accept it?”
