Fabric Lumacell Light Set



Smart looking, discreet 'be seen' lights with decent brightness and burn-times

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.

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

If you aren't a fan of lights spoiling the sleek look of your best race machine then the Fabric Lumacell lightset is a good choice. Their minimal size and cool oval design mean they are barely noticeable when they're switched off, but turn them on and they are surprisingly illuminating.

  • Pros: Subtle design, rubber band clamp means they'll fit anywhere, great waterproofing
  • Cons: Low battery warning light can only be seen on low modes

For their size, the Lumacells really kick out some decent light, the front 30 lumens, the rear 20. Fabric has used COB technology, that's 'chip on board' – or in basic terms a strip of LEDs which are housed behind a nylon cover to spread the light. Fabric claims they offer 180-degree visibility, which is technically true but so little light is actually sent out to the sides that, unless you are in complete darkness, you won't be seen.

The LEDs are bright in the middle, with the rest of the light offering a healthy glow, so you should be easy to see from the front or rear. Neither light is bright enough for sunny daytime use to really make a difference, but if things are overcast or you're out at dawn or dusk they are surprisingly noticeable, especially on the high mode or flash.

Claimed burn-times are pretty good, with high at 2.5hrs, medium at 4hrs, and low and flash coming in at 8hrs. Each of those is easily achievable as well.

The only downside I found was that the red LED on the front light to show battery life isn't visible unless the light is in low or flashing mode, so it can be easy to miss that you've only got a few minutes left.

To charge the lights you simply remove the rubber cover to expose the USB and plug each light directly to a power source – ideal if you are a commuter and have access to a PC. A full charge is achieved in two and a half hours.

Clamping is dealt with by a rubber strap, and the great thing is it'll wrap around anything. Aero seatpost? No problem. My main road bike has an aero, flat topped handlebar/stem setup which means nothing fits when it comes to light brackets, but the Lumacell bracket stretched round and I could position the light horizontally in front of the stem.

The rear light doesn't take into account the angle of the seatpost, so it points down towards the wheel rather than straight out, but as long as you position it high enough towards the saddle it's not really an issue. When it's dark it casts a nice glow over your rear wheel and the ground behind.

When it comes to waterproofing, the lights are IPX5 rated which means they can stand up to water jets from any direction.

We've had some decent days of rain lately and I've been using the lights on bikes without mudguards with little issue, but just to make sure I've given them a blast of the power shower, again without suffering any kind of ingress.

Fabric suggests a price of £36.99 (a saving of three quid over buying them separately) for the set, which isn't bad. BBB's Spy Combo is nearly £50, and while they're about six quid more expensive than the Xeccon Geinea lightset, you are getting double the power output with the Lumacells without sacrificing battery life. I think they offer pretty decent value for money, especially as they seem to be well made and are easy to use.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
