So I received my Niteflux Redzone 8 and have used it for a couple of commutes now.

The light is very bright. It has a blast like effect. Bathes everything near in light unlike other lights where the beams are more on the narrow side. Niteflux suggest that they need not be positioned in any particular way. However I've noticed that the light does shine brighter in the direction in which the LED faces. So I take care to rotate the light in order that motorists have the best chance to see it.

Seems to be well built with strong materials. A velcro strap is used to attach on to seat post, rack bag or anything handy. Battery life remains to be seen.

Interesting point of note. The battery (not sure what type) is supposed to be voltage regulated so when the battery weakens the light does not dim along with it. If the battery can't produce the required voltage it just stops working. Fortunately the light is supposed to have a built in battery level measurement that warns you of low charge via "single blinks", and "faster single blinks" that a recharge is in order.

Far too expensive at $99, but I'm hoping it will last me long enough to warrant the expense.
