5) Not confirmed yet. (All-in-one) = 15 Pcs.
6) Let us name model number after we confirm the specification.
7)
8) Followed the model we talked WS-605-5W, which I send you ppt to explain.
9) It provides dimer lighting. - 50% = 12 hour OK OR - 100% = 6 hours
Your requirement: have 100% 10 hours , then 50% BECOME = 20 hours.
In this case, we increase solar panel into 10W and increase the battery INTO 12.8V 3.2AH OR 6.4V 8AH.
CAN U verify and confirm this standard, then I revert you with possibity.
(to check if lighting metal case need to be bigger to hold the battery and total cost of this new standard unit)
I have question, HOW SHALL WE ARRANGE THE SHIPPING?
