Obviously that's not a picture (above) of the full brightness, or indeed any of it... use it in the dark and it's likely to irritate anybody behind; not so much because of the intensity, but because of the pattern. Of course the Mini and the Micro are nowhere near the blinding output of the Viz 300. But having owned a Micro and still do. Even 25 lumens can be pretty blinding and dont ask me how I found that out. (just dont look directly at it and turn it on)

Or buy a Rotlicht instead, where you can replace (and recycle) an exhausted battery. I'm getting the sense that you can't do that with the Cateye? The Cateye AMPP 100 Lumen Front Bike Light is a solid option for riders looking for the perfect combination of lumen output, weight, and price Minor niggles aside, the specification and performance are favourable and the price is good, although there's still a fair bit of competition.

As the name suggests, Cateye's Viz 450 rear light can throw out an extremely bright beam, although the full power is reserved for an intermittent flash in the 'Daytime Hyperflash' mode. In some specific use-cases you might appreciate this amount of power, but for most cyclists it is overkill and potentially a little provocative. There are more socially acceptable modes, but you could also just buy a less powerful, cheaper light. The shortest claimed run-time is a useful 5hrs, and that's pretty accurate – surprisingly it's not for the eyeball-grilling 300lm 'Daytime Hyperflash,' which can signal nearby planets (probably) for up to 10hrs, but for the 30lm Constant mode. Steve described this mode on the Viz 300 as luridly chaotic and it is – it's not just the bonkers output of those bright flashes but all the various rapid strobing that's going on at the same time, which makes this hard to ignore. Following behind this light in the daytime, I found that from around 100 metres it was very effective at being impossible to miss (and not overly bothersome) but from 10 metres it was pretty irritating. I didn't ride with this mode at night, so cannot report the thoughts of other road users. I would only use this mode if I was doing a lot of riding on fast A-roads in the daytime, and it would make me feel safer in that specific environment. I also avoided the Daytime Hyperflash in anything but strong sunlight, because it's so bright and so luridly chaotic it's like riding around on a distress beacon. Again it's a personal choice, but I don't want to give the worst drivers another excuse to throw a cretinous shut-your-eyes pass.

One thing I did notice though is still the use of micro USB. With the move of many electronics now to USB C, it would be nice to see companies making this change on bike lights as well. Plus with the higher potential power draw for faster charging, there is an additional upside beyond just being able to plug the cable in either way up. Group ride is also a surprisingly good choice for these duties. That said, something like the Knog Cobber Mid Rear Light is a superior choice for nocturnal couplings, but a good deal dearer, too. The Flashing mode dishes out just 15 lumens and is noticeable in the dark, if not exactly outstanding – and again, it's hypnotic in its pattern design. At least its strobing effect is noticeable under streetlighting.

I found the final mode – Group Ride – the most useful. At 100lm it's bright but not tactical nuke bright, and it's actually easier on the eye than the dimmer flash as it always seems to leave something lit. So, the modes are a bit topsy turvy. The one I got the most use out of, day and night, was the Group Ride mode due to its more subtle flash pattern. With the LEDs being lit longer it gives better side illumination too.It's hard to tell exactly, as looking at this straight on can literally make your eyes hurt, but Group Ride appears to switch each LED between two brightnesses, and leave either two dim or one bright one on at all times. Thus it's never fully dark, and consequently easier on the eyes (I was looking from the side, in case you were wondering...).
