Cateye impresses with the new Volt 800. It's quite possibly the best single-barrel LED front light on the market right now.

Front lights are normally relatively easy things to buy – you just decide how much light and battery life you need, match this up with your budget, and away you go. Let's deal with these three critical variables first off: as the name suggests, you get up to 800 lumens; you also get an impressive battery life of up to 80 hours (2hrs if you use it on the full high beam); and it's all yours for £99.99.

Of course, 800 lumens of light will draw significant energy from the battery, but the seemingly measly 2-hour battery life is extended to 3.5 hours when used on the mid 400 lumen setting, and 8 hours when on the low, 200 lumen output. Throw in a 'hyper constant' mode, which runs constantly at 200 lumens with a strobe pulse of the full 800 lumens for 7 hours, and a flashing 200 lumen mode which extends life to a sizeable 80 hours, and you've got enough flexibility to customise what you need.

For a typical commute of up to an hour, you'll get away with using the full beans for both rides if maximum forward visibility is your thing; if you just want to be seen for long periods of time out on a club ride, the flashing mode will suffice, with a simple switch over to a constant setting easily done to get you home in the dark.

The beam on the road is impressively wide considering the single-LED output – it covers cycle paths with ease, as well as the vast majority of the road in front of you. At the 800 (and I think even the 400) lumen setting, it's also very adept at helping you pick out obstacles in the road, and even when the beam is set on the road, the latent light bounces back off road signs in much the same way you see with car lights – they really do stand out.

One side-effect of the 800 lumen setting is that you do get quite a lot of heat generation from the bulb. After just 10 minutes of use I found this became a slight issue when removing the light once I got home – but taking a little care you can avoid the front end of the barrel, and after a couple of minutes the heat subsides anyway.

Once it's cooled, you can then easily remove the battery from the bulb end and charge it using the USB connector. Cateye has obviously realised the USB connector requires a little extra waterproofing so has fitted a rubber cover; it certainly can't hurt, and doesn't impede easy charging.

The recharge time is a claimed 5-11 hours, which is quite a range. For my part, I used my USB 3.0 connection on my computer to recharge the battery, which from near-empty charged fully in 8 hours. I just kept this topped up after each day, which meant I didn't have to think about battery life too much. Cateye claims you can fully recharge the battery a sizeable 300 times before life drops below 70 per cent of its maximum.

Overall, the build quality is excellent too – from the bracket to the screw-on battery, everything is well machined and fits like a proverbial glove. This means it's waterproof and dealt with rainy conditions without any issues at all – although I always took the time to dry the unit before unscrewing it for recharging as a matter of common sense. It's not a particularly lightweight unit, but then it's not noticeably heavier than rivals either.

Fixing the light to the handlebar isn't as easy as the rubberised brackets used by some brands, but it's not far off. You tighten the bracket to the frame by turning the fastener, and the light then mounts by sliding into a secure clickable interface. You then press the catch at the front to release the light and slide it off again. In short, what the bracket loses in ease of fitting, the light gains in security.

Also available is a centre fork bracket, as well as a helmet mount. Both are good options, although because the Volt 800 isn't super-light you're going to know after a couple of hours' riding that it's on your head.

So, is this the best single-barrel light on the market? It's certainly one of the highest-performers. I found the 800 lumen output to be spectacularly good, and at a minimal weight penalty with plenty of options to maximise battery life. Build quality is great, as is the bracket and the fitting options too.

At a penny under £100 it's not cheap, but then I hear arguments every day that you can't put a price on safety – so I'm inclined to forgive it somewhat for this. It'll last for years if you look after it, and give you unparalleled visibility for the size of the unit. I see it as a top investment, if you can afford the initial outlay.

A very timely reivew, as I've just been looking at this light mysef.

It's also worth noting that the batteries are interchangable with other Cateye Volt front lights. It also uses Micro USB, which I have multiple cables lying about all over the place, so recharging is never an issue!

I've currently got a Cateye Volt 300 and an old Blackburn Scorche, and I'm so impressed with that I'm planning on replacing with the 800. Fingers crossed Father Christmas is reading this

Another owner, great light - reassuring build quality. But please, for Merckx's sake, mount in under the bar - looks infinitely better

You haven't really thought this through, have you?  If you swivel the mount through 180 degrees the light points backwards.  Doh!

I am happy with the review. 

I have one as well and I think it is amazing value for what you get.  Its slim and good weight for the output you get.  I commute to central so hyper constant is what I need but I always recharge it at work so I don't get any anxiety that it will die on me on the way home. 

The mount is very secure as long as you always remember to hear that click in to make sure it is locked.  Taking it off is relatively simple as well. 

I did look for another spare battery but it turns out to be over £30 when I only paid £79 for the whole light so maybe get one on sale. 

Overall I really like this light and I own a lot of lights (probably 10 front and 10 rear of all differnt make and models) and I think this has to be my favourite commuter light. 

If I have to chose again now I will buy this over any other.

Great review. I'm looking forward to replacing my old Cat Eye Nano Shot with something like this or its older Volt 700 brother. The Nano Shot's small-capacity internal battery isn't holding a charge anywhere near as well any more, so the external cartridge batteries of most of the Volt series front lights is a massive boon in this respect.

I do have a Volt 1200 which I use for almost all my rides. Cat Eye's biggest strength isn't ultimate luminosity, but the versatility of the output options. For my commutes, I ride on the middle 600-lumen setting and it's plenty bright enough to see with on Manila's unfriendly streets - while lasting a claimed 5 hours, which I find is generally accurate.

One weakness I've found though is the light body itself is an easy target of corrosion from sweat salts. That's probably the reason why the second series of Volt lights, including the 800, now come in a black-painted light body. On my Volt 1200, it got to the point where the removable battery got more or less permanently seized onto the light body. Best to dry it off each ride as best as you can with the battery removed.

That said, I'm looking forward to either this Volt 800 or my light's successor, the Volt 1600 - just because the 1200 was, and still is, such a great and flexible performer.

Be aware though, that they're not all the same spec battery.  The battery that comes with the Volt 300 has a lower capacity (2.2Ah) than the 700 and 800's (3.1Ah). 

You can buy the 3.1Ah battery separately though, which I did for my Volt 700, and it's a good thing to have in your pocket in case you've got a long ride in the dark where you need full power and one charge might not be enough.

Whether I'm right or wrong (there's a song there) I devided against the Volt 800 when it came to replacing my Volt 300 and got the Volt 400 despite the Volt800 being vastly superior in the tests/ reviews  sad  I decided I didn't need a massive improvement on the 300 which was good enough for unlit country lanes (I'd back it up with a smart lunar 35 though and will probaby still do that) and the recharge times of the 800 were just a little too long.  You've probably found otherwise though to make me sick
