Light output and modes
The output of up to 2,200 lumens and claimed range of up to 300 metres are particularly useful when riding after dark away from lit streets. The stated range alone, however, does not indicate how clearly a particular obstacle on the road will be visible.
The SL06 offers six lighting modes, including daytime flashing, strobe and SOS. It can automatically adjust its brightness to the ambient light, so the intensity does not always need to be changed manually.
The light enters sleep mode after 45 seconds of inactivity. It is not specified what counts as inactivity or whether the light stays on when stopped in traffic, so riders should not rely on it doing so without checking.
Battery, charging and power bank
According to the stated specifications, the 4,800 mAh battery provides approximately four hours of continuous light at maximum output. Charging via USB-C takes around two hours.
The light can also be used as a power bank, for example to give a smartphone an emergency charge during a trip. Energy used to charge a phone will reduce the power available for subsequent lighting, so it is worth allowing for that when planning a longer ride.
Construction and box contents
The light has an aluminium-alloy body. Its IPX6 rating means it is protected against powerful jets of water, making it suitable for use in rain. It does not mean the light is protected against immersion in water.
The box includes two mounting brackets, a USB-C charging cable and a brief manual. The brackets attach the light to a bike, but compatibility with specific handlebars is not stated.
