Blackburn Flea Solar 2.0 4 LED USB front light



Clever light with reasonable output but starting to show its age

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.

What the scores mean

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

The Blackburn Flea Solar 2.0 4 LED USB front light is perfect for touring and audax since it can be charged using the sun's energy - but has a USB option, an absolute godsend in dwindling daylight. However, despite these gizmos it's starting to feel dated, dare I say impotent alongside the latest generation of eighty lumen plus rivals.

High quality plastics house four super-bright Nichia LEDs, fed by a Li-on cell. Incorporated within the winter glove friendly diamond shaped switch is the brand's easy read 'fuel-gauge' battery indicator. Used properly, this not only reduces the likelihood of being plunged into darkness but counteracts damaging overcharging too. So far so good...

Not so impressive is the crude but effective Velcro backed handlebar or helmet straps , which feel distinctly low rent and need to be removed to charge. Two tiny magnets protrude from the light's base, connecting to the docking station, which you either plug straight into the nearest USB port or solar panel, James Bond style. Undeniably a talking point, this latter technology is best employed during bright sunny days, since overcast November skies meant full charges took six, sometimes seven hours.

Output and runtimes are distinctly average, not the sort I'd be comfortable relying on should disaster strike, but having said that, the crisp white beam nails driver attention at around 200, maybe 250 metres on a clear night and has made a very effective pairing with the brands' Voyager 2.0 commuter lamp in flashing modes, especially entering the flow of traffic, or alerting pedestrians along shared paths.

58 minutes is close enough to the hour quoted for its highest setting, two hours, forty two (standard) and but five hours seemed unattainable on the low setting. Even with direct USB fuelling we've managed four hours and thirty three, twenty minutes less using solar energy, which is disappointing.

LED Fuel Gauge

The innovative LED battery fuel gauge/charging indicator is cleverly integrated into the power button of both the Flea and Super Flea lights. Now you no longer have to guess how much battery life is left, just follow the simple color code. Green = 100% - 75%; Orange = 75% - 25%; Red = 25% - 0%

Rate the light for quality of construction:
Rate the light for design and ease of use. How simple was the light to use?
Rate the light for the design and usability of the clamping system/s

Adequate rather than amazing - disappointing given Blackburn's usual standards.

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

Fine in everyday service and the "no quibble" replacement policy certainly adds peace of mind.

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

Performance lags behind its beefier sibling and I've never managed the full five hours claimed, regardless of charging method. That said, the "fuel gauge" seems accurate.

Rate the light for performance:

Good relative to size and as a contingency/dynamo companion but showing its age.

Rate the light for durability:
Rate the light for weight, if applicable:
Rate the light for comfort, if applicable:
Rate the light for value:

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

There's no doubt the Flea commands driver/pedestrian attention to a reasonable distance and better than its forty lumens might suggest. We're very much in contingency territory and run times between fuel ups weren't particularly generous.

Tell us what you particularly liked about the light

Characterful design, good output relatice to size.

Tell us what you particularly disliked about the light

Modest run times and solar chrge isn't overly practical during winter.

Did you enjoy using the light? Yes.

Would you consider buying the light? No.

Would you recommend the light to a friend? Possibly.

Overall rating: 6/10

Think you might have the details of the Flea 2.0 (£25) mixed up with the Super Flea (£40).
