Moon Comet X Pro Front and Rear Lights

I have been using the Moon Comet lights on my bikes for many years, ever since they were first launched. I think they were one of the first to use COB (chip-on-board) LED lights, which gives a nice glow instead of sharp points of lights.

If you look back at my previous posts, I have been using the Moon Comet front light and also the Moon Comet rear light since year 2013, and they are still working fine! That is very impressive for a bicycle light.

However, recently the plastic Bracket that holds the light to the bike broke, and I had the choice to buy a new Bracket or buy a new light. Although the lights are still working, the battery life is now significantly shorter than before. This deterioration of battery life is to be expected due to repeated charging and discharging cycles. Therefore, I decided to retire these first generation of Moon Comet lights, and get a new set as replacement.

There is a specific reason why I still want to use these Moon Comet lights, as you can see later. Other than being good lights (bright, compact, lightweight, rechargeable), the Bracket that mounts it to the bike is special.

Moon Comet X Pro Front Light. The Pro version means a longer battery life compared to the non-pro version.

Other than being lightweight, there are multiple steady and flashing modes to make any user happy. Claimed runtime is also stated here for future reference.

Other than the light, a USB charging cable, 2 rubber bands, a saddle bag clip, and a special mount is included.

The light has a clear transparent casing, so the internal battery and electronics can be seen.

Charging port is covered with a rubber flap, and a Micro USB port is now used instead of the near-obsolete Mini USB port that was used previously. I wouldn't mind if it was the latest USB-C port either.

Light plus special Bracket and rubber band weighs 46 grams.

At the same time, I bought the rear light as well. Although I already have the Cycliq Fly6 CE rear light + camera on my Cervelo Aspero, I wanted to use this rear light as a spare light. As already proven previously and also subsequently, it is necessary to have a spare light to augment the Fly6 CE, as it is not known for long battery life.

Product information is in a different format compared to the front light. Optional accessories are also listed here.

For the rear light, other than the standard set of accessories provided with the front light, there is an additional saddle Bracket as shown at the top left corner.

Layout is the same as the front light. ON/OFF button located at one end, charging port at the other end.

Instead of having a clear transparent casing, it has a red transparent casing. Most likely it is the same plastic mold as the one for the front light, just with a red dye added. Clever way to save on different injection molding toolings.

Battery runtime and brightness stated clearly in the manual. I'm not too interested in the claimed lumens. If it looks bright enough to my eyes, it is good enough.

Here is the reason why I like these Moon Comet lights, because the innovative Bracket allows the front lights to be mounted on the front fork legs, freeing up space on the handlebars. This was first used on the Avanti Inc 3 commuting bike, where I mounted the Moon Nebula W front light. After that, I used it  successfully on the Canyon Endurace as well.

If I'm going to put front lights on the fork legs, might as well put on a pair for symmetry. Having two also allows built in redundancy, as it is very unlikely that both will run out of battery at the same time.

I mount them low enough so that the light from the opposite fork leg can shine through the wheel, instead of being blocked by the rims.

The special Bracket has a hinged V-shaped clamp that can be fixed on narrow fork legs, aero seat posts, or any round cylinder. Additionally, there is a sideways tilt, which is what makes this Bracket so versatile.

Mounting of the rear light is pretty standard on the seat post. The sideways tilt comes in useful again to shine the light horizontally. Normally the Fly6 CE will be there instead of this rear light.

The light is lightweight, compact, slim and bright. Only downside is the slightly higher price, but I think it is totally worth it.

I highly recommend this light, not just for the innovative Bracket, but for the overall package of compact size, lightweight, good brightness and battery life.

It also solves a problem that many road bikes have, where the front light cannot be mounted on the aero handlebar due to the shape or the size. By mounting the front lights on the front fork legs, visibility is very good, while it does not take up space on the handlebar or under the computer mount.
