18650 or CR123A
See everything in your path with this bright, 1800 lumen bike light. This compact light is versatile to handle any situation with it’s six brightness levels. Power this light with either four CR123A batteries or two 18650 rechargeable batteries.
I love this light. I live in the Pacific Northwest and cycle to work. A good headlight on my bicycle is a must. Being able to swap batteries easily is wonderful and means I won't be fumbling my way home in the dark after work if I forget to charge up.
Brightness is excellent. I use this mounted on the front of my aero bar loop and it works great. Distance and spread of light is very good. I also use the blinking feature during the day. Battery life has been very good. I got more than the rated life on high using 2600mah batteries. Also going to try the 3500. Very happy.
Like the way it attaches/good lighting
I've had this light going on four years now. It performs exactly as advertised. Same two batteries. Very happy with it. Yes, there is a problem with the battery holder ring. I'm just very careful with it. Fenix should make a effort to improve the problem.
I road bike the Houston bayous at night. We "spin" at about 17 - 20 mph. At 500 lumins, I have a friend who rides behind me, without a light. Gives me confidence that I can go "full gas" in a training session at night. My ride is 43 miles. Always have about 44% charge left.
Just an amazing light for the money. Disclaimer: I got this light in September of 2015 with a 30% off deal. It's performance has been nothing other than flawless for almost 4 years now. I'm using Samsung 25R cells and they give me over an hour on Turbo mode while using the hyper speed switch frequently. Carry an extra pair or 2 of cells and you're good. The twin beam design is ideal; a spot and a wide beam. You really couldn't ask for more when it comes to a fixed setup for pavement riding. Combine this and a good helmet mount light and you have a durable and reasonably priced setup for night single track rides.
This light is amazing! I bought it because of the flexibility to use either rechargeable or 123a batteries. The color of the beam is great it doesn't have that annoying blue tint I hate so much. It is rugged and stays where you put it . Altogether a great bike light. Fenix shipped out my order right away . Great company to do business with. I also have a BT10 bike light that is going strong after three years which is now relegated to my helmet. Great combination!
