Nuke Light 3W LED front light



Very capable front light bright enough for commutes, yet light enough for the best bike

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.

Something a wolf in sheep’s clothing, the Nuke Light enjoys neat, albeit slightly boxy styling and a small lens suggesting very meagre output. However, clever optics and several settings ensure you can see and be seen-even on pitch-black rural roads. Convenient run times, a choice of either mains or USB charging coupled with keen pricing means its one of the best compact designs I’ve used in a very long time.

Powered by mobile phone type Li-on battery, the Nuke light employs six-lens technology, reckoned to deliver a whopping 540 lumens at a metre-on full (flood) beam. That's probably underpowered for anything resembling bridle path, but for road riding it provides a clear and accurate view of conditions chasing along unlit country lanes at close to race pace. Other settings are less impressive but suitable for urban commuting or as complement to a dynamo system thanks to run times ranging between three and forty hours (flashing mode) from a single charge.

Using a clever heat-sink ensures consistent charge and run times-even in sub zero temperatures while the positive switch prevents it accidentally turning on in the bottom of a bag but is easy operated wearing full-finger gloves. The tool free mounting bracket could be improved- it’s very secure and there’s plenty of shims to accommodate the whole spectrum of handlebar diameters but a broader tension wheel would make for easier attachment/removal.

The very modest 120g weight is a clear advantage over slightly dated bottle battery type lights and as well as being a good commuting light for unlit roads would be my choice for enjoying those late summer evenings on the best bike. Be mindful not to snag the delicate wires on the USB charger though and higher output LED or possibly HID systems are better suited for more serious use such as prolonged nocturnal rides/ winter training.

The Nuke light is a rechargeable front lamp powered by mobile phone size Li-On battery and intended primarily for commuting. However, it's deceptively powerful on full beam and generally good enough for training on unlit rural roads.

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

The Nuke Light really impressed me with it's ability to illuminate unlit roads rather than just be seen with. Charge and run times are really good too, although the less powerful modes are only suitable for urban use or complimenting a dynamo system. Tipping the scales at 120g it's light enough for the best bike or simply popping in the seat pack. The USB charger could've been a little more substantial but this is a minor point.

Tell us what you particularly liked about the product

Low weight, great output, and easy charging.

Nothing worthy of note, although tool free bracket head could've been slightly larger.
