I didn’t measure the throw before I took the XPE out. It throws further though. The light is noticeably brighter in both flood and spot.
I have a couple other modded zoomies that I recently switched from dedomed XPG2 to dedomed XPL. They have much more flood and noticeably more throw with the XPL when run on a 3 amp driver on a fresh Kinoko INR 14500. These are tiny zoomies… just 87mm x 21mm. But they get around 17k lux and probably put out around 1000 lumens, both have much more throw than the Coast HP1, but perhaps that’s not surprising since the HP1’s spot mode is also designed to have some flood. These same lights only got around 15k lux when they had dedomed XPG2 inside.
My brightest zoomie is my modded Aleto N8. Currently with a 20mm aspheric lens inside. It’s smaller than the HP1, but runs on an 18650 and has a FET driver. It has a dedomed XML2 instead of an XPL and gets 31-33k lux…. much better results that I got with XPG2.
