Pros: Insanely bright for the price.
Easy to set up and use.
Has different size o rings to allow either handle bar mount or head band.

Cons: Cable a bit short, and comes out frontways from the lamp, but easily sorted with cable tie.
Also fitted the battery pack onto the back of the headband, but would be nice to have the cable long enough or an extension to be able to mount on a belt/ backpack

Other Thoughts: I used this to run a team of 10 huskies through the woods at night and not only lights up every dog in line but the main focus beam can still light up over 100 metres away with a nice flood lighting up the surrounding area.

Bottomline: Buy this or the other 5 mode one. They are superb light for the price. Going with the reviews/ beamshots I have seen, they are just as good as the lupine systems but a fraction of the cost.

Pros: For the price paid, this is an excellent light. The construction appears to be very solid and it work right the first time. For the price this light is exceptionally bright at approximately 700 lumens. I used it on my ride home from work a couple days after I received it and it worked well. It appeared to be brighter than the majority of other lights that I saw in the bike trail. A comparable light in terms of brightness, you would have to spend at least five time the price. I will likely purchase a couple more of these in the near future.

Cons: There are only a few things that I would like to see improved with this light. Amongst the improvements that I would desire would be a longer power cord, or a power cord extension. When the light is helmet mounted, the cord is too short to reach a pocket. The battery needs to be attached to the helmet or if your wearing a hydration pack, one of the shoulder straps. When mounting the light on the handlebar, the short cable length is ideal.
When the light is mounted on the handle bars, the beam is not wide enough to accommodate lighting the turns. This cause me to have to slow down considerably so that I can navigate the turn safely. With the width of the beam being a bit too narrow for handle bar mounting, a helmet should be provided. I altered the head strap that was provided with the light so that I could helmet mount the light.
No instructions were provided with the light, which is not too much as a problem. I was able to find a manual on a web site that sells the same light.

Other Thoughts: With all things considers, there is no way you can go wrong this light. It is bright, weather resistant, light weight, and it looks good. For the price, you can by four or five of them as compared to buying one of another brand of comparable brightness. I don't expect to get more than two to three years of service with any light without having to replace the battery pack. I was able to find replacement battery packs on a couple of web sites and you can buy replacement batteries for less than $40. Replacement batteries for the more expensive light will likely cost four to five times the price.

Bottomline: I will buy more of these lights without hesitation, and I will recommend them to my friends.

Pros: I use this light for riding both on and off road, i would definately say full power it far to bright for the road, it is however excellent for off road trails.
Medium power is also a little exessive for the road too, however when there are no street lights, medium is perfect!
The backlite button is very nice and easy to find at night.
Took the light apart to check for swarf as this has been mentioned in reveiws of the other identical light on this site, No sign what so ever!
The light actually just seemed to get better as i took more componenets off.
The billet machined aluminium body is nicely machined, don't know how they can do it for the price.

Cons: Gets very hot indoors, so i can imagine this would be an issue outside in the summer.
Thats all!

Other Thoughts: The flashing mode is useless. It feels like I'm in a disco. It would have been nice, others have already commented, to have a lower level mode when riding around town.
This light has quite a "floody" beam. It would be nice to have a model available (or perhaps just a reflector option) for more of a pencil beam. I'd like two lights on my bike - a flood and a spot. Plus two lights are always better in case one dies and your still out in the bush.

Bottomline: This really is a top end light and not just for the money either.
Probably not quite 900 lumens but not a million miles away.
