Here is my surefire lights.
Z2 combat dual xpl hi and dual 219c… 2345 lumen @30 seconds.
6p quad xpl hi. 2212 lumen @30 seconds…
They are very bright for the size… most light around that size only put about 1500 lumen…
I set my lights to 3 modes… great heatsink! Medium and 50 lumen mode are good and no overheat… those two are my keeper…
