At road.cc 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 road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
Oxford's UltraTorch SF Silicon front light is a very simple and surprisingly capable safety/contingency light, with three modes and excellent surface area. However, this design is among the most widely copied and some nigh-on identical store brands' represent better value for money.
What we have here is the classic fit 'n' forget cartridge comprising a single diode, switch and rechargeable lithium-ion cell, which delivers reasonable bang for modest buck. This is encased in a weather and shock-repelling silicone monocoque with integral strap.
Talking of which, the recessed charge port's location and plug are extremely well conceived, snug fitting and sandwiched between the light body and your handlebar for additional protection from the elements. Charge times are approximately 2 hours at the mains, another 30mins when guzzling from laptops. Either way, the lens will emit a solid green light when fully juiced and it has the courtesy to turn red when reserves drop to around 25 per cent, giving ample opportunity to get home and refuel.
Superficially identical to a wealth of competitors, such as the BTwin Vioo (£9.99) and the Revolution Flash (£8.95) it employs a watch strap type bracket that locates with a plastic pip, which is less convenient than press-fit designs but ensures incredibly secure tenure across the full zodiac of handlebar diameters. It even entertains fork legs and head tubes, should you prefer.
The centre-mounted switch is exactly where you'd expect to find it and intuitive to use. Pressing and holding for two seconds engages the brightest setting, whereupon you simply toggle down to suit. Unless you've buried it in the bottom of a bag, unwanted power-ups are in blue moon territory.
The brightest setting is just about good enough for town work and navigating unlit backstreets, although I'd draw the line at canal paths, and it's run for 4hrs 47mins.
As for being seen, other traffic spotted me from around 70m on relatively clear nights, and peripheral bleed maintains this presence when emerging from side roads or negotiating roundabouts.
Low isn't much cop, frankly, although it sips reserves to the tune of 6hrs, which could make all the difference in an emergency.
Thankfully it's redeemed by flashing – a decent pulsing strobe that works beautifully paired with old fashioned dynamos, or as backing singer to a more powerful rechargeable system. Returning 8hrs 51mins from a full charge, little surprise it's been my default for dull wintry afternoons. It's distinctive enough to stand out in seasonally lit town centres, and other vehicles acknowledged me from 100m, 150m in less-built-up areas.
Competent safety light, but nothing special
