The Ravemen FR1100 shows just how much light you can get out of a tiny package these days, and it’s not even the brightest of these lights – there’s a 1,500-lumen version too. The short battery life and diffuse beam mean it’s better as an emergency light than your go-to for night riding though.

The FR1100 is barely bigger than a GPS computer – indeed, smaller than some – and it’s designed in such a way that you can mount it on your out-front mount and stick your computer on top.

It comes set up for Garmin and Hammerhead, and Wahoo and Bryton mounts are also included. It also ships with a nice out-front mount, and you can hang it below that and angle it to get the light where you need it.

The light is mostly a plastic body, but there’s an aluminium heat sink and mount on the bottom. The single button and the USB-C port are on the left-hand side. At the front are two LEDs capable of punching out 1,100 lumens into the night.

The light is rated IPX4 for waterproofing, which really is the absolute minimum requirement here in the UK.

The beam shape is slightly flattened, but not as much as Ravemen’s other lights, and overall it’s a bit diffuse. If you’re going quickly, you’ll need the High mode, because the second mode (500 lumens) is less than half power. The third mode is half that again on paper – 250 lumens – but out on the road doesn’t really look much different.

The bottom line here though is that if you want to ride at speed on the road, the full beam certainly produces enough light to do that. Going from Low beam to High does however involve moving through the three flashing modes, and the button isn’t the easiest to locate or use, which might make for an interesting few seconds when you feel you need more light on a tricky descent.

Battery life from the 2,500mAh battery, unsurprisingly, is not long: about 2hrs on full beam from my testing, although it drops to a lower mode as the battery depletes.

I’ve moaned at Ravemen for their battery charge indicators before, and here I shall do so again: if you turn this light on and it’s green, that could mean anything between 100% and 40%. If you turn it on and it’s red, that could be 40%, or it could be 5%. Not good enough.

The FR1100 will act as a power bank in an emergency. It really will have to be an emergency though, because the battery isn’t a big one. It could get you out of a hole though.

Ravemen makes some great lights, but this one feels like it falls between two stools a little. If you want a powerful light then there are better ones out there – Ravemen’s own K1000, for example (£64.99), or the Exposure Sirius 11 (£120) – and if you want an emergency light to sit under your computer then the cheaper FR500 is probably powerful enough.

If your specific use case requires you to have a light you can mount under your computer that’s powerful enough for unlit lanes at speeds, then this will definitely do that job, but for most people another light will probably work better.
