The 15-lumen steady is up to the job of built-up areas; I seemed to register on friends' radars at 70-80 metres. Run-times The Cateye Viz 100 is a good rear light that covers most bases well. The only thing that merits some revision, to my mind, is the strap. Verdict 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) 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. 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

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? ViZ100] φ21.5-32.0mm. Fits up to 130mm outer circumference. (SP-15) Recharge/discharge number of times： about 300 times（until the rated capacity drops to 70%） Water resistant： [AMPP200] IPX4 The rest of the burntimes are 15 hrs, 11hrs and 70 hrs as you drop down through modes. After a few charging rounds I found those times to be easily achievable on all but the coldest of rides. Sub-zero I'd say they drop by around 5%.

Lights Buyers Guide

The most startling thing about this light is how bright a mere 40 lumens can be when funnelled through effective lenses. The constant mode is very bright when seen from 300 metres away at night, and vastly more so than the higher lumen output from the lens-less Knog Blinder Skull. On this basis, unless your commute takes in a lot of fast daytime dual carriageways (my sympathy), I just don't think a case can be made for needing more than 10 times this output, as here. So Cateye decided it would be a great idea to discontinue the cheap and much loved Rapid Mini and Rapid Micro lights just so they could bring out a new product line with more eyeball searing lumens than you'll ever need that does nothing apart from blinding everyone behind you and inflating the price, Just so they could make more money off you. Although functional and reliable enough, it's a bit fiddlier than others, especially in the dark. Exchanging it for an oversized o-ring type improved matters. Modes

All Rights Reserved Company No. 05107467 | VAT No: 593 733 507 Returning to the review, I honestly cannot see how anyone thinks 300 lumens is appropriate for a red light aimed at following vehicles or riders, whether at night or in daylight. I find 30 lumens is more than enough to draw attention. The Viz 150, which appears to have a very similar shape, has more than enough punch and is significantly cheaper than this unit. The ladder strap hooks into lugs either side, and I've had no issues with standard round profiles between 25.4 and 30.8mm. It's compatible with some box-section trailer tubing and helmets, too.That doesn't sound very bright, but the 30lm glow from all three LEDs through the transparent case is actually pretty eye-catching outside of bright sunshine or night-time commutes. 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.

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. On the bike the CatEye ViZ is simple, secure, effective and long-lived. The clamp needs a bit more attention once you remove it – and if you don't use lights on bright days it's a bit excessive – but other than that it's very good; it gets the job done well. Verdict Positioning it vertically has a small but palpable edge, especially at junctions, negotiating roundabouts and just performing turns in the road – particularly so when I've tethered it to my low-slung trailer. Though it has a smaller surface area than I'm usually comfortable with attaching to a trailer or tagalong, the daytime mode more than compensates, especially in such contexts. But you can use standard AAA batteries with Cateye's inexpensive Omni and LD610 rear lights, which are still available.With an 8hr claimed run-time from the 800mAh li-ion battery, Group Ride is very usable too. I certainly never had it shut down even after multiple rides, as there's ample opportunity to top up before it gets critical (and a red warning light at 1hr left, when it also switches to a special power-saving flash pattern). Value Bargain on being visible at 125 metres (about the length of a football field) on a clear night, dipping to 80 when it's cloudy. The overall build quality is up there though, and I like the angular style CatEye has gone for on their higher models. It looks at home on a modern aero frame, so won’t be cramping your style for the pursuit of safety (nor performance at only 47 grams)!
