Foreword: We are using a limelight, and all the below is based on the green LED on it.
We found the issue was not with the light reaching the other side of the field, but having the correct camera resolution to still see it. The zoom feature of the limelight help us, but I would definitely do some testing if you are using your own camera.
I would also like to remind people to tune for other’s lights. There were matches in 2016 that I remember people using flashlights cause other’s vision tracking algorithms to go amiss. I was at no fault of the flashlight user, but rather that people didn’t consider this as a possibility. (We sure didn’t)
