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!
