Cateye Volt 800 front light



Others are snapping at its heels, but the Volt 800 is still pretty much king of the single-barrel hill

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Cateye is still onto a winner with the Volt 800 – so much so that it's done almost nothing to the product since my review of it in 2015. The two changes it has made, however, make it just as impressive as it was three years ago.

  • Pros: Still class-leading performance
  • Cons: Not much

The Volt 800 is almost precisely the same unit it was three years ago. To remind you if you don't want to reread that review, the Volt 800 impresses with a compact single LED barrel profile, 800 lumens of potential output on static, a wide beam profile, with a selection of three useful flashing/strobe settings when being seen is more important than seeing where you're going.

Build quality is also still up there with the best, incorporating the same screw-in replaceable battery design (but integrated USB connector for charging), as well as the same light unit and interface, plus easy-fit, semi-permanent bracket for the handlebar, and optional others for the fork and helmet.

Back then it got 9/10, and despite the £99.99 price tag and slightly chunky 135g weight, it was probably the best light of its type to be tested at at that time.

In 2018, there have been two changes: the battery unit has been boosted in capacity to 3400mAh from 3100mAh, and the price has dropped by a tenner.

Any price cut is welcome, as always, and thanks to the excellence of the original design, £89.99 still buys you a whole lotta light. There's a gain of a single gram on the scales – inconsequential – and the battery itself adds in the region of 5-10 extra minutes to overall burn times when on the static modes.

What it does notably claim to do is double the time on the strobe-only setting – up from 50 hours to a claimed 100 – and reduce empty-to-full charge times from 11 hours to 9. In reality, charge times are practically the same, perhaps reflecting the slight increase in capacity married to a more efficient internal architecture.

It's hard to make direct comparisons because the Volt 800 I already had from the last test has been well used, so the battery in that unit is aged and naturally not quite as efficient as it used to be.

It raises an interesting point, though – the battery units have the same design, which means if you already own a Volt 800, you could just opt to buy a new battery to refresh your existing unit, for £39.99. Of course, to do that you want to make sure that the existing light unit and LED is in good condition to make the most of it, but it's worth considering instead of replacing your whole light.

That said, should you not already own one, the slightly updated Cateye Volt 800 remains among the very best single-barrel lights around, although even at a tenner cheaper it's not exactly bargain priced, with others – such as the Lezyne Lite Drive 800XL, Kryptonite F800 and Giant Recon 900 – that can now meet the same power output for less money.

Rate the light for quality of construction:
Rate the light for design and ease of use. How simple was the light to use?

Super-easy to use, with handy memory function.

Rate the light for the design and usability of the clamping system/s

The clamp is easy to fit and remove, and the light fits with a slide-and-click interface.

Rate the light for waterproofing. How did it stand up to the elements?

Zero issues.

Rate the light for battery life. How long did it last? How long did it take to recharge?

Very good battery life and recharge times are acceptably speedy.

Rate the light for performance:

There are lights that can put out more lumens than the Volt 800, but they cost more.

Rate the light for durability:

No complaints here, borne of experience. Only the bracket is a slight weak link to look at but my old one is still working well.

Rate the light for weight:

A 1g increase over the 2015 unit is nothing.

Rate the light for value:

It would have earned one mark up compared with the previous version, thanks to the £10 reduction in price and very slight increase in battery performance, but there are now others that can match the power at a lower price point.

That it's ostensibly the same as the 'old' one.

Tell us what you particularly disliked about the light


How does the price compare to that of similar products in the market, including ones recently tested on

Infini's Tron 800 is more expensive, but there are others that put out the same lumens for less – like the Lezyne Lite Drive 800XL, Kryptonite F800 and Giant Recon 900 – which you can see compared for real in our beam test engine.

Did you enjoy using the light? Yes

Would you consider buying the light? Yes

Would you recommend the light to a friend? Yes, it's probably still the standard-setter as an all-round single-barrel light, even with some sturdy competition these days.

Use this box to explain your overall score

If Cateye had upped the lumen count to 900 or more to show willingness to push the unit forward without compromising the rest of the light, it might have earned a 10.

Overall rating: 9/10
