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.

ETC's Capella 800 front light is a tidy enough package, with 800 reasonably focused lumens, good side visibility and a sturdy adjustable mount. However, the beam isn't shaped to prevent it pointing into the sky, wasting lumens and dazzling drivers alike. There's not much warning of a low battery either.

Compact yet feeling hefty at 125g, the ETC Capella is a physically attractive light with an anodised metal body.

The mount clamps solidly to your bar, and then you can remove or reinstall the light. The bar clamp is the traditional Cateye-style grooved strap that passes around the bar and then through a threaded ring which then screws down tight.

A bonus is that it can mount forwards or backwards, the light able to rotate 360 degrees in solidly clicked increments. This is handy if you have cables or other bar apparatus to clear.


The Capella charges from underneath using the provided 23cm micro USB cable sucking in juice at 0.8A (not the claimed 1A on ETC's website, but more than the 0.7A stamped on the light itself), the button blinking while charging. ETC claims two and a half hours, I measured it as four hours to 100% full using a current meter. Once charged the light turns solid blue.

A useful trick is that you can charge and run the light in Breathing mode at same time – possibly good for touring or really long day rides where you might want to run it as a day light off a dynamo hub or similar, then into the night.


There are four modes to cycle through with a click of the button: High at 800, Medium 400, Low at 200, and 'Breathing' which varies between 50 and 100 at about one-second intervals. These modes have run-times of 1hr 20mins, 2hrs 10mins, 4hrs 30mins and 18hrs respectively. Memory mode is always on, where the light turns back on in the last-used setting.

Finally, there's an absolutely bonkers Strobe mode accessed via a two-second-long press. The ensuing lightshow wouldn't look amiss in a Norwegian Death Metal Eurovision set.

One omission is a High-Low beam two-way mode, which Lezyne and others have introduced, albeit at a slightly higher price. This means you have to cycle through multiple button presses if you need to dip the light from High for oncoming traffic and back again, which is annoying. 


In High, using all 800 lumens, the Capella is good enough to crack on at about 15mph on completely dark roads or tracks, depending on the surface, wetness and surrounding light. Unfortunately, when projecting the centre of the beam far enough out to be able to ride at that speed and react in time to hazards, the unshaped beam is throwing half its output skywards or into the eyes of other road or trail users.

Going lower than full power means riding pretty slowly – it turns into a 'be seen' light instead of a pothole-spotter. In a halfway see-or-be-seen light there's inevitably a compromise of beam spread – focused for speed vs broad for closer-in surface awareness and off-centre illumination for other road users. ETC has got it as close enough to good enough as I can imagine at this price point.

The basic conical beam is pretty darn close to that of the venerable Exposure Joystick Mk10, another 800-lumen light but one specifically designed for use as a helmet-mounted trail corner/hazard spotter. For me, the Joystick edges out the Capella in the beam focus stakes, but it's not really an apples-with-apples comparison.

The body has cutouts on either side with yellowed lenses casting out quite a decent amount of 'see me' light to alert other intersection users to your presence. Possibly not that visible in the wet against an urban background, mind. One downside of this 'feature' is that if mounted on a drop bar it really lights up your hoods/hands, which then detracts from your night vision in complete darkness.

Run-times were on the generous side of the indicated durations, but be aware that once the red light kicks on at 20% you can't get High power anymore, so if you need High for riding at 15mph+, you're limited to just over an hour before it's Medium.


Despite some shortcomings, 800 lumens and a decent mount for £40 is a pretty good deal.

The Lezyne Micro Drive 600XL is £50, a bit dimmer on spec and with a slightly shorter run-time on full power. But with a more focused beam and a high/low mode for riding in traffic, it could be a more useful option for the extra tenner.

Its more powerful sibling, the Micro Drive Pro 800XL, is a £60 light with only marginally better beam and brightness. But you get a longer run-time of 1hr 45mins and 50% charge indication – likely worth the extra £20 for hardened nighttime commuters.


Overall, for £40 the ETC Capella is a pretty decent light. Certainly good enough to get a commuter to or from work along dark roads, or to keep yourself visible in traffic. The mount is solid and there's not really much to dislike aside from the beam shaping, no High-Low mode and limited battery level indication. ETC really should throw in High-Low and a 50% amber indication on the next iteration to improve user-friendliness.

Rate the light for quality of construction:

Feels and looks premium.

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

One press on/off and memory mode – what else you need? – apart from High-Low mode, that is.

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

I liked it. Can be reversed to clear bar stuff, and rotated 360.

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

IPX6 rated, and no issues.

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

Lasting over an hour on High is good, but the level indication is lacking. Charge time of 4hrs isn't great.

Rate the light for performance:

The beam does waste a lot of energy, and the lack of charge awareness makes you nervous.

Rate the light for durability:

Feels solid enough to last a battering.

Rate the light for weight:

Reassuringly hefty.

Rate the light for value:

800 lumens and a decent mount for £40 isn't bad – the Magicshine Allty 800 is £15 more, and the Lezyne Micro Drive Pro 800XL is £60 – but the Magicshine's beam is more focused with more usable light where you want it, while the Lezyne has a longer run-time and 50% charge indication.

Tell us how the light performed overall when used for its designed purpose

Well enough, once you realise the battery needs keeping an eye on.

Tell us what you particularly liked about the light

The mount is nice and hefty, very adjustable.

Tell us what you particularly disliked about the light

The beam shaping. And no High-Low beam mode.

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

The Magicshine Allty 800 is £15 more, but the beam is more focused with more usable light where you want it. At only two-thirds the price of the £60 Lezyne Micro Drive Pro 800XL, with similar beam shape and only slightly less focus, it's a good alternative to the big brands.

Did you enjoy using the light? Yes

Would you consider buying the light? Yes

Would you recommend the light to a friend? Yes

Use this box to explain your overall score

The unshaped beam and lack of a 50% battery indication mark the ETC 800 Capella down, and no High-Low beam mode is annoying. Which is a pity as the build quality and mount are great, and 800 lumens for £40 is bangin'.

Overall rating: 6/10

I'm pretty sure you can buy this exact light for $25 on Aliexpress. It's called Gaciron V9C-800

Source: I got one.

Wonder if and how that would change the rating.

KiwiMike replied to Smultie | 3 years ago

You're right, it's probably the same light. It wouldn't change the review score, because price and therefore value are based on UK RRP and comparison with other products at UK RRP.

How's the Alibaba warranty returns process, and appreciating everyone likes a bargain, what do you think about supporting local bike businesses?

Warranty returns are probably shitty, although I have had refunds for non-working products by just showing them proof (picture or movie of non-working product).

And yes, I do support my local bike businesses as much as possible. But should I just hand them 25 GBP for a part they probably also bought from Aliexpress in bulk? Nah, not me at least. They should offer a premium for the extra money.

KiwiMike replied to Smultie | 3 years ago

ETC is the house brand of Moore Large, one of UK's biggest cycle distributors. So your LBS would mark it up from UK trade price.

Looking at Aliexpress right now, that light will cost you £31 incl postage to UK, and take three-four weeks to arrive, and as you say, the warranty process is probably 'shitty'. 

Go wild with that £9 you saved, hope your light doesn't break...genuine question: when your LBS goes broke and you can't get that urgent part/accessory (or help with that stuck BB / misaligned frame/brake caliper/whatever) - who do you turn to? Aliexpress?

"the beam isn't shaped to prevent it pointing into the sky, wasting lumens and dazzling drivers alike"

Good to see these fundamental defects highlighted in the review. Maybe eventually manufacturers will stop trying to flog overpriced torches and start designing cycle lights fit for purpose. Kudos to the reviewer.

matthewn5 replied to Sriracha | 3 years ago

Exactly this. I've looked through years of light reviews looking for a light that isn't just a useless round beam that dazzles oncoming cyclists and puts the light where you don't need it. This article explains why shaped beams are so important:
