Assuming the camera settings are manual, that ZL is clearly brighter. Just look at how much more light you’re getting in the spill.
Also doubling lumens (with the same beam profile) usually appears only about 25% brighter to the human eye.
As far as flood vs throw (the ZL HI models are definitely not “floody” lights BTW, they have a much narrow beam than many similar lights even from ZL) any light than is going to the spill isn’t being concentrated into the hotspot. Its always a tradeoff in where that light is going. How wide the hotspot itself is becomes a huge factor too.
