Review – Moon Sport Rigel Max Front LED Bicycle Light

Moon Rigel Max Front LED Bicycle Light Review
Moon Sport Lights produce some of the best bicycle lights on the market—over the last five years I have intensively used many of their LED front and rear lights, and have been consistently impressed with their quality, performance and design. The Moon Rigel Max front bike light is a compact white LED light, with some intelligent design features and functions.

In the box you receive a Rigel Max light, helmet mount, Go-Pro mount adapter, handlebar bracket mount, and a USB-C charging cable. It is worth noting that the Rigel Max quarter turn mount is identical to a Garmin mount—offering you a plethora of further mounting options.

Lighting Modes

The Rigel Max has two static modes: pre-set to 1500 lumens and 500 lumens (main and dipped beams). However, thanks to Moon's VLS (Variable Lumen System) you can fully customise the set-up to reduce or increase the power of either of the two modes. The VLS system allows you to extend battery life considerably, by reducing the Max output to extend run time.

Flashing mode is accessed through a double-click to get to a separate menu. This menu consists of Flash 1, Steady Flash, Day Bright Flash and SOS.

The full 1,500 lumen beam gives you just 1 hour 40 minutes of battery life; 500 lumens lasts 3 hours and 30 minutes, while flashing modes offer 48 up to 120 hours.

Beam Function

The Rigel Max has an inbuilt refracted lens to stop you dazzling oncoming drivers or cyclists; looking at the lense this is seen through the ridges on the upper plastic half. If you mount the light under the handlebars, you can remove the plastic lens unit and flip it over, so it still retains its function.

Performance and Operation

Testing the light on the roads and trails this winter, I have been impressed by the reach and spread of the Rigel Max front light. It is a relatively broad beam, picking up a wide range.

The light is operated through a single button on the top of the unit, which also doubles up as a mode indicator and battery life warning light. You can also use the Intelligent Operation (IO) by pressing the mode button for three seconds when powered off; this detects darkness and turns itself on automatically—making it good for variable light condition rides.

To save battery life, the Moon Rigel Max has a Intelligent Motion Sensing Function that automatically dims to light after 20 seconds of inactivity; then turns the light to standby when the bike is static for more than 60 seconds. After one hour the light completely switches off. A great way to conserve battery life.

Mounting is simple and secure thanks to the plethora of mounting options. The Rigel Max is also IPX7 rated (submersible to one metre for 30 minutes – in case you drop it in a large puddle!).


Like all other Moon lights I have tested, the Rigel Max is extremely well made and designed; with many clever functions. It retails for £89.99, which is a competitive price for a do-it-all front light of this quality level.

Compact, powerful and clever – this is another winner of a winter bike light from Moon.
