Thanks for the kind words of support, it means a lot to me
All the lights are rotaries,
two are triples
the output of the triple 219b 3500k 9080, falls right between the two samples of single 219b 4500k 9080.
It seems lower CCT makes less lumens, and the triple brings it back up a bit to essentially match the 219b 4500k 9080 (if we average the two samples)
the triple 219a 4500k 9050 has the lowest lumens among the magnetic rotaries
the HDS w 219b 3500k 9080 has the lowest output. The circuit it lower power than the five magnetic rotaries (Jetbeam/Niteye, which all share essentially the same driver). HDS output is essentially about half that of the other five lights.
.
and here is a test of how many lumens it takes to hide a shadow with a triple vs a single led in a reflector



I have no way to measure actual throw, but Im guesstimating the triple throws half as far. otoh it also illuminates more than double the area
.
Here is an outdoor shot, the single LED at 430 lumens throws a narrower beam, farther than the triple at 310 lumens (battery is not fully charged):


although the hotspot of the single LED is brighter, smaller, and throws farther, it also makes more glare.
I prefer the wider beam of the triple for close range and indoors, the single LED for outdoors at distances over 30 feet.
I prefer the 4500k for daytime EDC, and the 3500k for nightime.
