Sure. I own the Whitezone 5 and Redzone 4 lights, which I understand corresponds to 5 watts and 4 watts of output - approximately 400 and 300 lumens respectively, but blasted all around.

Here is a video of these lights mounted on my folding commuter bike, tested out in a car park near to my place. The Redzone is about 6 months old in this video, whilst the Whitezone is new.

The Whitezone is set to a "fast blink" sort of mode, whilst the rear kind of "strobes". The blink settings can be changed fairly easily. Both lights are on full power. In Singapore where I live the roads are well lit and so lights "to see" are not necessary. But on the other hand there are a lot of vehicles on the road with plenty of background light pollution from shops 'n such, and I also read that cyclists are more likely to get hit side-on as opposed to being rear ended, so I thought I'd opt for all round power in order to clear that light "noise".

These lights do a good job, but if my Redzone 4 were to die out on me I might upgrade to the Redzone 8 as a replacement. Maybe not to run at full power but at a healthy 5 or 6 watts, a tad more than what the Redzone 4 blasts out.

The lights are well made, and nigh well weather proof - even unto heavy rain, but maybe not water proof. I received the lights with a velcro strap and cable ties. The velcro goes around the light on to whatever u want to tie the light on - it is shape independent. The cable ties are little short to go around much - I haven't figured out their purpose yet.

Charging is by using a micro USB cable (provided). Removing the polyurethane caps to expose the charging input can be really hard for the first several times of use. Niteflux recommends using vaseline to make this easier. But too much vaseline can cause the cap to fall of with vibration if it is mounted vertically - so just the minimum to be applied I think. The polyurethane cap yellows after a while on exposure to air. This is natural and it has happened to my Redzone in the video. The brightness of the light does not seem much effected. The white light may become yellower with time I guess.

I'm guessing that with time the batteries will lose their capacity to hold, but looking inside it does not seem overly complicated to replace. The caps will also lose their elasticity, but Niteflux sells replacements. Basically it's a simple light with lots of light thrown everywhere. Easy to mount onto anything. I have not really come across anything similar to it in the market.
