Review – Nite Flux Red Zone 8 400 Lumen Rear Light

Bike Review Nite Flux Light

I like products made for cyclists by cyclists, and when they’re Australian cyclists, it’s much more likely to address my situation, since I’m also an Australian cyclist. Made in Adelaide, the Nite Flux Red Zone 8 Rear Light is possibly the most powerful rear light on the market, pumping out 400 Lumens of red light over a 300 degree spread; more than enough to be seen very clearly, even in the daylight.

The Nite Flux looks significantly different to most rear lights on the market. It’s a carbon fiber tube with a large battery inside (it looks like an 18650 or similar) which is mounted to a circuit board. The circuit board has a usb recharge port on one end and a red button on the other. The tube also has some cutouts on each end and the exposed circuit board at these points has two little red dots mounted to it. I mention this specifically because I was looking for the LEDs and the lenses (it is a light, after all) and couldn’t find them, so I hit the red button and HOLY CRAP I’M BLIND. Those little red dots are the LEDs! Seriously, if you could make this product go “bang”, you could sell it to the military as a stun grenade. There’s a lot of light coming from those tiny little dots.

While having exposed LEDs like this all over your bike would make you visible from the moon, having a car hit you because the motorist was blinded by your lights is probably something you would want to avoid. Fortunately, the Nite Flux has silicon end caps which weatherproof the device and provide useful light diffusion. Even diffused, the light is wonderfully bright and overpowers everything else I have in my rear light arsenal.

The Nite Flux takes about 6 hours to recharge fully via a USB cable and gives you around 100 hours of flashing red light on its lowest setting. If you run it on solid, it will give you 120 lumens for 3 hours, and if you ran it on its highest flash setting at 400 lumens, it will give you a four hour run time. I hate having to mess around with my cycling gadgets every day, so I tend to choose products that will give me a commuting week’s worth of run time (for me around 8 hours) and then charge the gadgets all at once. I ran the Nite Flux on a combination of flashing modes and it never ran out between recharges, so it’s a good set and forget product for me. If you are the type who doesn’t want to set and forget, you can follow the instructions provided with the light and change the flashing patterns and strength, so you can customise the light to suit your riding needs.

The benefits of this light are pretty obvious: it’s very bright, bright enough to see in the daytime and from kilometres away during the night. I’ll add to this that it’s a very simple and straight forward product to use. These two pros are enough to sell it and it’s definitely a product I would buy. There is a major downside that’s worth mentioning, which may factor into your thinking, and that’s the Nite Flux’s size; it’s quite large and will take up a lot of your seat post space, if that’s where you want to mount it. I can’t run this and the Fly 6 on the same post. Mounting it on the seat stays (on the right hand side, where I’ve mounted secondary rear lights before) wasn’t an easy option with the mounts provided, but the straight foward design of the Nite Flux lends itself to other options and the manufacturers produce a range of alternate mounts. I don’t use a saddlebag, so mounting this horizontally under the saddle would probably be the best option for me. It’s also easy to transfer between bikes, so one light and a few mounts is all you need for your stable.

It’s a different looking light, but it works very well. The Nite Flux range includes a lower powered rear light (Red Zone 4), as well as two white lights (to be seen by, not to see with), the White Zone 5 and 10, all of which have the same form factor. They’re all worth having a look at and may be just the safety lights to fit your bikes and riding style. The 400 Lumen Night Flux Red Zone 8 reviewed here is priced at $150 which includes shipping. You can get these lights online from Full Beam Australia.

    Hi David,
    Had to laugh about looking at it directly without the cover. Did something similar the first time I looked at my 900 Lumen front lights – never again !!!

    Question – is the price worth the features & visibility of the light ? $150 is quite a bit, so that is an issue for me.

    What is the warranty with the light ?

      Have a look at the Nite Flux site. They seem to have good support and service if you need it. For a regular commuter, it might be a bit of overkill, but for longer, darker rides, like an Audax, or a bit of bike touring, it’s probably one of the better options out there. It’s a serious light and it is expensive, but if you’re a heavy user, it’s worth it. As I said in the article, you buy one and a bunch of mounts and you’re golden for the whole stable.

    Search this website if you want to see what they used to be like – hopefully they have improved. It was very bright, actually it still is but you have to hold the button on as it turns off after a few seconds.

    It was replaced under warranty. The replacement had the same issue a few months later but was outside the warranty period and I gave up.

    I bought the first generation of the niteflux lights a few years back – both are still going strong and are still pretty much the most visible lights on any road I am on. Low level flash is perfect for group rides.

    I’ve got both the white zone 10 & red zone 8 lights and they are amazing!

    Flash mode is too bright for night time riding, but find steady-on keeps you seen, coupled with a less powerful blinky (helmet light for me) is a great combination.

    Traffic does react to you and gives you a wider berth.

    Once the electricity went out at home, and these lights served well as a ‘camping light’. They last quite a long time on a full charge considering the power they put out.

    One note, keep the silicone covers lubed! If they go dry, they are a bugger to get off.

    I love my Nite Flux red Zone 8. It is way bright enough on its lowest setting and the charge seems to last forever. I do a lot of night riding and couldn’t recommend this product highly enough.
