Discover the run light specificities

Clearly lights up the road in front of the runner

The beam of the Run Light is perfect for lighting the first 20 metres in front of a runner, 5 metres wide, allowing them to see where they are putting their feet and to avoid obstacles.

The advantages of the Run Light compared to a headlamp

The Run Light, Kalenji Innovation, is a lamp you place on your chest, as a replacement or in addition to a headlamp. From this position, the Run Light lights up the ground from runners' feet to up to 20 meters ahead of them, compared to headlamps that tend to light up the ground well ahead of runners. Moreover, the Run Light is more comfortable. Held in position around the body, it does not move, whereas a headlamp may feel tight around the head, fall on the face, feel warm and even change the position in which runners hold their heads.

3 light intensity settings For any situation

Contrary to Watts that indicate energy consumption, Lumens measure light intensity. Settings:

1) 90 Lumens: suitable for urban running under street lighting (5 hours of autonomy at 90 lm when fully charged + 1hr at 70 lm)

2) 180 Lumens: suitable for dim light conditions (3 hours of autonomy at 180 lm when fully charged + 1hr at 70 lm)

3) 250 Lumens: recommended for running in total darkness (2 hours of autonomy at 250 lm when fully charged + 1hr at 70 lm)

(Note: One additional battery may be added to increase the autonomy)


Easy to charge

 Charge the battery (by plugging in or via USB cable to your computer) for 5 hours to have 100% autonomy



Check charge at a glance

Light charge indicators on the back of the runlight battery: 3 lights = fully charged, 2 lights = 2/3 charged and 1 light = 1/3 charged.

Easy to attach and wear around the torso

The beam of the runlight is placed on the torso, with the battery on the back; the vertical strap is positioned over the right shoulder. The device clips on the side and the size is easily adjusted by sliding the plastic loop.

    Brilliant bit of kit!

    This looked like a really good alternative to a head torch and based on the other reviews I thought I would try it. I am very glad I did as it is brilliant. It charges easily via USB and so far I have not needed to recharge it even after multiple uses. The illumination is very good and for road running I have only needed the lowest setting. I find it comfortable to wear and having a light on the back is a good addition.

    Overall I highly recommend you try it.

    Running in the dark!

    I live in an area where running in winter is very restrictive without a light. I've never got used to wearing a head torch. In the past I've used ankle and arm lights. These illuminate you but not the road ahead.

    I bought this product in September. Lets say it has transformed my running over the last few months. Running along country lanes cars actually slow down when they see you. The light illuminates a long way.

    Best running product I've bought for ages!
