CATEYE Unisex's Ampp 400 Front Bicycle Light, Black, 34 x 100 x 37 mm

I like the light, don't get me wrong.....the 400 lumens is bright enough for the unlit roads I travel at 25-35 mph, but when I am transitioning from differently iluminated areas, pressing the switch firmly enough to change brightness causes the light to move downwards. The switch ideally needs to be positioned above the mounting position, not ahead of it. (Edit; it's possible to tighten the bracket enough to prevent this without damaging it) The switch is also difficult to double-press whilst wearing gloves. Both of these factors mean that you really need to reduce speed (or stop) to change modes safely, taking a hand of the bar to reverse your wrist so you can support the underside of the light to prevent beam deviation whilst you press with your thumb means that I find it easier to use this light on max brightness throughout my 45 minute commute, recharge at work and max it home, not sure it will do 90 mins on a single charge, anyone else had similar experiences? (Edit; yes, it does, but not on max power!) I like the mounting bracket, it offers a few degrees of side to side adjustment,the light is easy to remove and slips into a pocket without any uncomfortable protrusions. The beam is bright and illuminates a good stretch of the road ahead, with plenty of side spread illumination for bends and curves. The charge port is well sealed by a captive cover. Edit; I have increased my rating from 3 stars to 5, very impressed with this light and I can recommend it.

This cateye bike light is amazing so strong & super bright especially considering we are now approaching autumn so shorter days, it has four settings a real bright beam a more subtle bram, fast flashing beam & a more slow flashing beam This product is reasonably priced for what it can do it's so easy to mount it's been through some pretty bad rain so it is most definitely waterproof & durable

I've had a number of CatEye branded bike lights before all of which have been nicely made and have been pretty bright in use - although none of them quoted their 'lumens' brightness (which suggests it's not their selling point), but for general use and for commuting I'd say they served this purpose pretty well. However, after having a few near misses cycling at night on ordinary residential roads where motorists haven't seen me and have almost come at me from the side at T-junctions, I figured it might be a good investment to buy a more powerful light and this relatively modest 400 Ampp light on first use I feel is quite impressive. This light is very bright at its 400 lumens setting (and could easily dazzle and irritate many motorists if not tilted down towards the road slightly), but it can also be set to a more moderate (but still bright) 200 lumens setting which I'd say is perfectly bright enough for most urban riding and commuting in street-lit areas. The CatEye 400 Ampp is easy to mount on handlebars and has an easily-operated switch placed sensibly on the top of the unit (so you can switch it on or off or change modes even when you're in the saddle), and it has a good quality feel about it which I'd say comes partly from the aluminium from which the body of the lamp is made. In my opinion, I don't think many cyclists riding in-and-around town would in reality ever need a much more powerful light than this 400 ampp (such as the CatEye 800 ampp or 1100 ampp), unless they expect to be riding in the pitch-black-of-night down country lanes a lot, or are hell-bent on dazzling motorists.

Excellent AMPP400 cyclist front lamp with bracket. Very bright, & adequate for purposes of catcing other road users attention & illuminating the way. Light penetrates dark roads with broad enough beam, including road signs & the ubiquitous pot holes or drain covers in the wet. Have used this as a torch in the home as a focus beam while searching around darkened corners & cupboards, too (v.bright, illuminating, & v.useful). Number of light settings including flashing modes, which perserves battery life. Judged battery life adequate for at least a daily 2 hour commute on full power mode (probably more), good for survival on those dark winter nights. Holds its charge well, so far. ONLY FAULT noticed is the waterproof power button. Similar, but larger version of, the rubberised buttons on a TV remote, which i assume activates a printed circuit board below. After one years use I found the power button became faulty. It wouldn't always work of power up. Pressing the button would not always activate the unit, or access to the various light settings with mutiple-presses i.e low light, flashing light, high light, flashing + constant light. However the unit will still eventually work with repeated attempts, & is bright & useful as ever. It's the standing around at the bike shed, pressing the thing until it works, & feeling a bit silly, which is the odd experience. Hopefully the manufacturer can sort the button, if they pick up the feedback. My guess, the rubberised button is to aid water proofing but needs a little finessing to make it perfect. Other wise, highly recommended lamp.

Easy to fit and adjust the handle bar mounting. Easy to fit and remove the light from the mounting. Not sure if this review is for the 400 or 500 lumen. 400 is plenty good enough for general commuting. We have a few and they’re used quite a lot. Bright enough for night time unlit tracks (we do not do fast downhill MTB type stuff!). Use flashing all the time during the day if on roads. At night use hyper flash on lit roads. At night use steady on for unlit roads. Battery may not last quite as long as advertised but pretty good. We take a spare with us for any lengthy nighttime trips just in case. Easy and quick to charge.

I have an ampp 800 for my bike that I ride at night and when I’m off at work. I wanted another for the bike I have at home. For this one I needed a light to be seen, and not to see with as I only really use it in the day I also wanted the hyper constant function (the light strobes but stays lit in between) as I think this gets you seen on your bike more. It does exactly what I wanted. If you want to see at night I would personally go for the 800 version, as it lights up everything better than a car headlight on full beam. To be honest the 800 is probably too bright. You could use this at night and see with it, and I am more than happy with the performance. Cateye seems to be good value for a good quality item. The mounting kits that come with the lights are nice and sturdy too.

The lamp is nice looking. It feels secure once fitted. I just need to remind myself how to remove it every time but that is just me being a bit thick... It is quite bright and it has a few options to choose from. These will affect how long the battery last, as expected. Overall, I am very happy with the price, features and quality from this brand. I also bought another one for the rear, so you could say I am a repeat customer

I've had at least 4 of the cateye EL-135 front lights over the years, and they've been amazing. Weeks worth of commuting though the winter. And if you have 2 sets of rechargable AA's then as soon as the batteries run out it's an instant swap. HOWEVER, I upgraded to this AMPP 400 (about double the price) when my last front light died, the fancy rechargeable lithium ion battery barely lasts 3 days of commuting. Total waste of money! I'll always be a fan of Cateye lights, but I won't be buying a rechargeable one any time soon. Back to the EL-135's for me

Es un producto de muy buena calidad, dura bastante la batería y lo principal ilumina muy bien

Piccola leggera e funzionale , da usare come 2ª lampada sul casco x illuminare dove quardi o in caso scendi o cadi dalla bici x capire dove sei . Utile anche in caso di riparazioni . Usata quasi sempre a 200 lm x aumentare la durata e a 400 nei tratti discesa x avere quel poco di luminosità in più .. Soddisfatto

Mejora la iluminación lateral con respecto a los modelos VOLT, pero a cambio en los AMPP la batería va integrada. Para uso urbano y no de oscuridad absoluta con 400 o 500 está bien y la autonomía es correcta. Algo lento de carga, pero acabo de empezar a usarlo a ver en unos cuantos ciclos de carga más. Buena potencia, función de máx (400), min (200) una modo que combina ambos y parpadeo. Siempre he usado CatEye desde hace muchos años y me gusta su calidad. Recomiendo mirar en su página web para elegir la potencia y autonomía que necesitamos para elegir el modelo que se ajuste a las necesidades de cada uno. Tampoco hay que volverse loco poniendo un cañón e ir bronceando al personal salvo que se necesite realmente mucha luz en trazado exigente. Yo lo uso para hacerme ver, en vías verdes, carril bici y uso urbano y es más que suficiente para mí. Mejor autonomía que el modelo 500, pero 100 lúmenes menos.

Até ver estou satisfeito com o desempenho da lanterna, nomeadamente a bateria, que dura muito tempo, pelo menos em modo flash.

Ottima qualità dei materiali buona durata della batteria reputo molto soddisfacente l illuminazione sia a 400 che a 200 lm. Ampio fascio. Adatto in città e fuori. Consiglio
