For those who don't know about Niteye, they are apparently related to the Jetbeam company which has been producing quality flashlights for years. They are based in China and use the latest in led technology in their products. This particular model uses 4xXM-L leds in four separate reflectors. It uses a battery carrier to house 4x18650 batteries and produces at maximum setting 3000 lumens. Operation of the light is done with a stainless steel magnetic rotating ring below the head. It has 6 positions which can be felt by distinct detents along the ring's travel. The ring has good knurling, although it's only on one side, which I found to be kind of strange, but in actual use makes no difference. All the way to the left is strobe and going right you have OFF/LOW(one led)/MEDIUM(two leds)/HIGH(three leds)/TURBO(four leds). An interesting feature with this light as with the EYE-30 is that with low only one led is activated and with each additional increase another led is lit up. There is also a beacon mode which can be activated by switching from strobe to off and then back to strobe quickly.
I've been using this light for three weeks now and I've used it for everything. I've taken it camping where there was no ambient light, so I was able to fully experience the sheer power.(see videos below) Surprisingly it had decent throw although it is mainly a flood light. This light truly put to shame all those campers who showed up with their hardware store bought lights and weak headlamps. I've used it going for a walk around a lake near my home, as well as in the home on the lower settings to navigate around late at night.
A few final notes on this light. This light does heat up rapidly on Turbo and it will reduce to 60% of it's brightness after 5 minutes to save the leds and batteries. There is a built in charging port which allows charging with the included 12 volt car charger. It does not balance the batteries when charging this way, so it is recommended to take the batteries out every so often and charge in a proper charger eg. Ultrafire WF-139 charger. The light does come with a carry handle as well, which is a nice accessory to have. It makes carrying this light easier and you can still manipulate the control ring while carrying it this way. The manufacturer states that this light is waterproof. It has a removable rubber plug to cover the charging port when not in use and uses o-rings at all the threaded parts. All in all this is a high quality light which is very nicely engineered and built with excellent anodising all over. At the time of this review it can be purchased for around $320CAD.
