Amazon LF 36 cycle light set review: An affordable front light for aero handlebars

The GoPro adapter makes mounting easier

With modern aero handlebars, attaching accessories is often more difficult than on round handlebars. Many mounts offer little space, cables are routed internally, and traditional rubber bands do not always stay in place securely. The LF 36 therefore relies on a combination of a handlebar mount and the GoPro mount supplied.

The adapter significantly expands the range of possible uses: anyone who already uses a compatible front mount beneath their cycle computer can position the light centrally and neatly. In terms of ease of use, the Amazon light scores 2.3, whilst the mount scores as low as 1.5. The headlight is therefore securely fixed in place during the test and is straightforward to fit.

The set also includes a rear light with a brake light function. However, this was not assessed in this comparison. The TOUR rating relates exclusively to the headlamp.

A uniform light pattern with some dark spots in front of the front wheel

In terms of light pattern, the LF 36 achieves a score of 3.0. The even illumination is a particular highlight: the beam appears uniform, making it easier to follow the course of the road in the dark. The light therefore provides useful guidance when driving on lit roads and in urban traffic.

However, illumination remains limited in the immediate area directly in front of the front wheel. Particularly on uneven back roads or when travelling at higher speeds, there isn’t quite enough light to spot potholes, kerbs or debris in good time. This shortcoming is more of an issue for sporty training rides on dark country roads than for the daily commute to work.

Short charging time, limited burn time

The built-in battery has a capacity of 1200 mAh. The LF 36 offers three lighting modes and, in tests, achieved a runtime of 2 hours 25 minutes. This means that battery life is not one of its strengths. Anyone who regularly goes on long evening rides should check the charge level before setting off or recharge the headlamp in good time.

This happens surprisingly quickly: the light takes 2 hours and 20 minutes to fully charge. The charging time is therefore on a par with the measured runtime. The battery level indicator is less impressive. The single indicator switches from green to red, but only provides a rough guide rather than a precise estimate of the remaining runtime.

Workmanship is decent; the overall package is clearly budget-oriented

TOUR rates the build quality at 2.0. The headlamp makes a solid impression, without standing out from the rest of the test field in terms of material quality or user interface. Its strengths lie in what’s included in the pack and in how easily it attaches to the front mount, rather than in maximum light output or particularly long battery life.
