One23 Intense Bright 1 Front LED Light



Competent commuter lamp for sub/urban riding but it burns through batteries quicker than similar lights

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.

One23 Intense bright 1 is a remarkably solid, well-conceived compact commuter lamp with excellent optics, weather seals and peripheral illumination that shames some household names. On the flip-side, Halos limit effective navigation beyond 15mph and battery consumption is pretty poor by modern standards too, although you can of course use rechargeables.

Thanks to competition and falling prices of technology, it's quite difficult to find poor lights-even at this end of the market. A single, ultra bright LED and clever collimator lens borrowed from laser guidance technology mean a crisper beam than ever before. LEDs might not be user serviceable in the sense of filament type lights but they're less prone to failures and cast a more useful pool of light.

Getting inside the casing is simply a question of rotating it anti-clockwise (towards you) revealing a neatly finished head and battery tray containing four AAA cells-very similar to RSP's Steradian with very neat soldering.

The otherwise nifty universal handlebar bracket supplied with integral shims for easy swapping between bikes is big compared with the latest generation of super slim rechargeables, something to bear in mind if handlebar space is limited and you need space for computers and other mod cons Directing the garden hose at the body and switch sections for five minutes couldn't reveal any obvious weaknesses, although as ever a quick lick of Vaseline on the contacts wouldn't be wasted.

Dusk comes with little warning these days so thankfully the top mounted switch is a doddle to use, even in winter gloves. Out in the sticks, high mode casts a crisp, piercing beam of the just about see by, you will definitely be seen-with up to around four hundred yards at 15mph; I found flashing mode particularly effective at cross roads/staggered junctions. Through town it's much the same story, although toggling down to low is perfectly feasible, conserving battery life, while the windows give plenty of warning to others when joining the flow of traffic.

The highintense bright1 is very competent for short, semi-lit commutes around town and occasional night rides. Peripheral illumination is excellent and the quality of light is relatively good for this type of light. That said, economy is poor returning 12, 17 and 22.5 hours from a set of alkaline cells, dropping to 10, 13 and 19.75hrs using nimh rechargeables.
