One of customers from Mexico, want to install 20W AIO in 6m pole, which install in double side of way.

Then we make dialux of 20W AIO in 6m to show him that it's too dark for the road, it must use more bigger power.

At last, we make 40W AIO dialux for him comparing as below:

From above comparing, we can see if light fixed in same environment, with power of LED light get more bigger, then performance get more better.

For 40W AIO, it plays perfect for this 10m width road comparing 20W AIO.

So customer choose 40W AIO at last, only because it is right choice.
