Brinyte XML-C8 CREE XML-T6 5-Mode 6700K 850LM White LED Flashlight with Strap (1*18650)

Pros: - BRIGHTNESS: 1. Maximum brightness. It is bright enough to ride MTB in night forest or fields with a high speed. 2. Medium brightness. I can ride night forest/fields with medium speed (15-25 km/h). Also it is perfect to ride on night city streets. 3. Low brightness. I use this brightness level rarely. Maybe only on night walks in forest park located near to my house. - BATTERY LIFE With a 2400mah battery on maximum brightness level it lives 1h 30min. I think it is good enough for such a bright flashlight. On medium level it lasts for about 4.5 hours. - BEAM I really likes the beam of this flashlight. Thanks to textured reflector the beam is wide and has a very good fill. You can see what happening on the road just under your front wheel. - CONSTRUCTION The construction of this flashlight is well. It's sturdy and strong. Some kind of water resistant - it takes several rains and a working in a snow without any problem.

Cons: - Some problem in heat dissipation, it can get overheated on maximum brightness if has cooling like an air running on you when you riding a bike. - I don't need 2 flashing modes.

Other: I've presented my Brinyte flashlight as a gift to my girlfriend's father so now I heading to buy another one to me. Very, very good flashlight for any applications. Best for cycling!

Pros: Bright LED. Textured reflector - no sharp edges of the central spot. Quite wide background illumination. Good driver with configurable modes (I have switched off SOS ans strobe by soldering two stars on the driver board). Positive contact has a spring. Threads are greased.

Cons: Reflector can not be changed easily (diode mount is threaded in reflector body). Bad thermal contact of the drop-in module (contact to the case only by the edge of the reflector. This is not good for such powerful diode.

Other: Ok for DIY, but not recommended to use at highest power without some modification of the diode cooling.
