The Moon Gem 3.0 (£18.49) and Moon Gem 2.0 (£18.17) are two USB chargeable bike lights distributed by Raleigh in the UK. This winter, these are the two bike lights I’ll mostly be using. Let me explain why…
The Moon lights are USB chargeable. Now I no longer have to remember to grab a £4 pack of batteries when the low light indicator comes on. I simply plug them in to my laptop. In the long run, this will save a lot of money, as well as bike rides without a light.
The rear Moon Gem 3.0 bike light is a similar size to the Blackburn Flea. Both have 4 Ultra bright LEDs achieving an adequate light output for cycle commuters. However, it wouldn’t hurt to supplement it with a secondary light. Perhaps the Knog Wearable Boomer or the Fibre Flare.
The Moon Gem 3.0 uses a clever bracket. This makes it very easy to quickly attach and remove the light from your bike. You can also twist the mount upwards. This is a fantastic little design feature as it means you can adjust your light, so it is not pointing downwards.
The front Moon Gem 2.0 use a similar mounting system, with a silicone strap that makes mounting quick and easy. The silicone strap and the clip looks like it can take some abuse, and I doubt you could snap it off unless you seriously mishandled it.
On the front bike light you can switch between full brightness and reduced brightness. You can also choose from different flashing modes. I’ve found myself mostly using the full power option. The manufacturer states that you get 19 Lumens of output. In comparison, The Knog Boomer states it has 50 lumens. However, I found the Moon Gem 2.0 to be brighter, which goes to show you can’t necessarily use the lumen figure as an accurate reading. Overall, it provides a decent amount of light for most commutes.
The power button is a little tough to press, and you wouldn’t be able to activate it with a pair of gloves. However, it also means the light is less likely to be accidentally pressed in your pocket or bag.
You don’t get a lot of battery life from the Moon lights, perhaps due to their tiny package. Therefore, every 6-8 rides you’ll need to charge them up again. However, charge time is very quick taking around 2 to 2.5 hours. There’s an indicator for when the battery is fully charged.
Overall, the Moon Gem bike lights are small yet bright, making them a suitable choice for most cycle commuters. Those looking for additional power output should consider something a little more powerful, such as the Knog O Blinder.Click to take a look at the Moon Gem Front Light Click to take a look at the Moon Gem Rear Light
