This drop-in has a nice beam, more flood than spot but still throws to 150 yards with ease. A lightbox test showed 449 lumen on high with one AW2600 18650. Med 206, low 99. I was so impressed I just ordered another. my only complaint is the low needs to be lower. This unit blew my Thrunite XML out of the water. Thrunite tested 337 lumen on high, 103 med, 26.4 low.
