Olight T20 Q5 is very bright, the beam pattern has been discussed by many users, for me, the beam looks very "special", small and tight hot spot with very bright spill.

Lux reading references:
T20 Q5: 3380 lux (2xCR123A), 3280 lux (2xRCR123A) 3390 lux (unprotected 17670)
P3D P4 (smooth reflector): 3050 lux (2xCR123A)
P3D Q5 (smooth reflector): 3480 lux (2xCR123A), 3300 lux (2xRCR123A), 3520 lux (unprotected 17670)

5 m beamshots: left-right, T20 Q5 (2xCR123A), P3D P4 (2x CR123A smooth reflector), P3D Q5 (17670 smooth reflector)


10 m beamshots: left-right, T20 Q5 (2xCR123A), P3D P4 (2xCR123A smooth reflector), P3D Q5 (17670 smooth reflector)


The level1 (high) runtime claimed from manufacture is 1.5h, however I got 130 min with flat regulation




I think total output of P3D-Q5 is brighter than T20 Q5, throw and runtime in max level are identical; it's hard to tell which light is better, dependent on what flashlight size and what beam pattern you prefer.
