I received my Delta (with spun finish) last week and I have not been able to remove the bezel, which would allow me to clean the face of the optics and/or the internal face of the front window :sigh:. Beneath the front window, the optics and/or the front window seem to be covered in smudges and what appear to be ridge lines from a finger print; however, these don't noticeably interfere with the beam quality.
Other than the smudges
, this light is a solid 10/10! Physically, this light is machined to perfection, with silky smooth threads and no detectable blemishes. I selected the 319A 5K emitters with unknown optics (as there was not a drop down menu available at the time of purchase) and they produce reasonable flood and exceptional throw, with a slight green tint when compared to a 4500K MCE in one of my Alphas. This light is more portable than I anticipated, and will be at home in my pocket during these dark winter months. Overall, I would recommend this light to anyone and will be purchasing one for my wife. If anyone has tips for coaxing the bezel open, please let me know! Great work, Jason and team!
