Kaidomain has had that for a while! Best thing to do is remove the driver and put a real one on it like the Taskled. It is severely underdriven. It is also a big floody spot. Although much tighter than the reflectorless triple XML.
We are looking to make dive video lights but everything seems to be too focused. Have you tried these LED with no reflector or lens? Or do you have a suggestion for elimating the spot?
