Small size with a big output, and at a very reasonable price especially compared to other similar lights.I had previously purchased a single head unit and was so happy with it I went for the 2000. The light itself is of solid construction, light color is a big plus to me, not so overblown that it seems to whitewash everything. Comes with a couple mounting options, recommend the flexible bands as they are more versatile and create a solid/snug connection.I use this exclusively for mountain biking and it is more than adequate. It provides plenty of light and a decent coverage zone. Raced with it at the 24 Hours in the Old Pueblo and it was perfect. This is a fast, open course, so a good lighting system is necessary in order to make sure you don't outride your light. Highly recommend for the money. The tail light is really nice too, very soft, flexible attachment, works great on the back of your helmet to provide some visibility higher off the ground from behind, so great for road riding at night. Recharges in decent time and runtime has not been an issue. Actually still not sure how long the battery can last on a charge as I haven't done a ride long enough to tap it out yet.I have always been a big Light and Motion fan and find this light to perform to the standards I have come to expect with L&M. ### ⭐⭐⭐⭐⭐ Bright light, lives up to it's claims *by G***Z on Reviewed in the United States on January 1, 2015* I am extremely happy with this light. It is extremely bright and I believe measures up to the 2000 lumen claim that it makes. One thing I do like about this light is that it has a very nice external, rechargeable, battery pack which is extremely well made. The fact that it has an external battery pack gives a much greater versatility This allows it to be used and a headlight or on a bike helmet, which allows it to be used in the areas of mountain biking, spelunking and camping. Because of its external battery pack, and it is variable intensity settings, the charge can last up to 20 hours thus making it ideal for multi day camping trips. This large battery pack allows it to go for up to 3 hours at a high, 100% brightness or up to 20 hours at the lower beam setting.The construction is of a very high quality with aircraft aluminum. Every part of this light and it's accessories exude top quality workmanship. It is also light weight.This light also comes with a "free" tail light which is also made out of high quality aircraft aluminum and is of very good workman ship. It is much better than any of the numerous bicycle tail lights I have. The light also comes with its own carrying case which is of top quality. I highly recommend this light for it's craftsmanship, versatility, extreme brightness and length of charge. ### ⭐⭐⭐⭐ Super bright ! *by G***G on Reviewed in the United States on June 6, 2015* Works great and VERY bright! I bought this light for night rides on my mountain bike, on difficult trails with uneven terrain. I needed something that would make the trail look like day. Boy this light does! I took off one star because the plastic strap that goes around the helmet mount is kind of cheap and weak, it sometimes comes apart. Other than that, everything so far seems high quality. I've only used the battery on high for an hour and a half at one time, but it has not gotten dim on me yet. I put the battery in my camel back and I don't notice it. I do sometimes notice the light on top of my helmet when I'm going through tight canopy with low branches.
