I was doing some lux readings with xt11 xml and solarforce xm-l2 3 mode drop-in and noticed that my solarforce is under performing on high .

XT11 was between 10240-10640 on high middle 2080 and low 70.1 lux at 1m

Solarforce with 1 battery was between 10670-11160 on high , middle was 2550, low was 247.

With two batteries high was 10520 -10900 , middle was 4240 and low was 1060 .


You can see below that the middle and low numbers make sense compared to my readings but on high there is no real change .

Solarforce specs

LC-XML2 (U2, 3 modes, 2.7 - 9V):
H: 540 lumens / 120 mins or 670 lumens / 165 mins
M: 150 lumens / 4 hrs or 260 lumens / 6.5 hrs
L: 15 lumens / 40 hrs or 65 lumens / 35 hrs
Lumens rating / runtime (using 1 or 2 pc of Solarforce S18650P (V3) batteries


Does anyone have similar experience with these drop-ins ?
My drop-in also has a green tint to it .
