I just received my Tiara C1 pro NW (4000K) headlamp and all I have to say is: Wow! So much light out of such a small size!
I compared it to my about 4 years old 10Watts LED light (Aimai SSC-P7), which was bright as hell at that time... but now? Sure, it is not as bright as when it was new, but the Tiara C1 is so much brighter in turbo mode! I can only see the hotspot of the SSC light, but the room is lit by the Tiara, which also has the better, neutral white, tint.
Unfortunately, armytek has no "killer bright" flashlight with 3x XM-L2.
