Contacted the client again and gave him a zoom meeting. The client introduced his warehouse in detail, but he did not confirm his idea with the client. The final plan was a revolving column with lights. The original plan was that the client would also remodel the roof. Get light, but the cost is too high, it is recommended to set a rotating column + 2 light rods, the customer agrees to the plan and quote again.
Now the client is having an investment meeting to determine the next step of the program.
