Guee Sol 700 Plus £59.99

This is a pretty heavy light (181g with the bracket), but we were impressed by the tool-free mounting system that holds it very securely to the handlebars.

The Sol 700 Plus can be rotated up and down, which is useful if you want to dip the light when you’ve got it on a high setting on narrow lanes, but does mean it can move up and down if you hit bumps. However, we liked the fact that the mount can also be used for Gopros and other action cameras during the day.

The Sol 700 Plus illuminates very well up to five-10 metres in front of you, while beyond this distance it loses part of its brightness. It has very good lateral brightness (in the range of three-five metres) which makes the border of the road very well illuminated.

The standout feature is the ambient light sensor that will automatically adapt light power according to the light conditions (and a maximum power of 700 lumens, to the medium on of 500 and the low of 250). The Guee Sol features five different light intensities: high (2.8 hours), medium (5.5 hours), low (eight hours), strobe (seven hours) and flash (13.5 hours).

The light is only available in black, is waterproof and has vents placed in the front to help prevent the light from overheating with prolonged use. Recharging is with a mini USB cable (seven hours).

It is both heavy — 181g with the bracket — and the appearance is not the best we’ve seen, but the ambient sensor on the Guee Sol 700 Plus is really smart.
