The Ravemen PR2400 is an ultra powerful front light with an extremely large battery capacity, and does brilliantly in full dark either on or off road. Despite the monster specs I found it great for my daily commute too – the wireless remote and clear OLED display make it very useable.

This light has two modes – Road and Mountain Bike – and the patterns in them actually differ. The latter throwing out far more light down the road and to the sides with all five LEDs firing, and Road using fewer for a more focused beam. Each mode has various brightnesses and, obviously, runtimes. For off-road it ranges from 600-2,400 lumen, whereas Road mode ranges from 100-900 lumen.

It’s the first time I’d really had to worry about dazzling other road users. In fact, I’d like to take this opportunity to apologise to the group of west-country runners who may have fallen victim to me trying out full beam… it’s safe to say that Mountain Bike mode is exactly that.

At 316g it’s a hefty bit of kit. The alloy body features the screen and two buttons, and those two buttons are replicated on the included Bluetooth remote. It’s easy to position in reach of a thumb, and the easy control is fantastic given how blindingly bright this light can be.

Something so powerful needs a battery that can pack a punch too, and this gets it. The PR2400 has 8,000mAh of juice, which is enough to power the full 2,400 lumen beam for around 90 minutes.

That capacity is also a huge advantage when you’re running at far lower (but still objectively bright) outputs for more ‘normal’ riding. I’ve really appreciated long gaps between charges. For example, I typically used the lowest Road setting (Eco) on my morning commute, to be seen, while on the way home I needed the 900 lumen High setting. With this mix and my short commute I only had to recharge it every 10 days or so. Obviously, everyone’s needs will be different, but one fewer device to remember to charge is always a good thing.

The OLED screen only makes everything easier still. It tells you exactly what mode you’re in and how much battery is remaining, making it very unlikely you’re going to get caught out and left in the dark. It can also act as a power bank if one of your other accessories doesn’t do so well, though note the power-out socket is an old-school USB-A. The charging port, meanwhile, is the ubiquitous and much more useful USB-C.

There are a few cons. Firstly, there’s the weight. Most dedicated road cyclists probably don’t need anything so hefty any more than they need the 2,400 lumen max power, so this more for riders who mix up on and off-road riding or, perhaps, ride an eBike. Personally, I’ve been using it in my all-road e-Bike, meaning that I didn’t notice the weight. It would be much less at home on my carbon road bike.

I found the clamp and mount sturdy and easy to use, though note it (and its two silicone shims) are only designed to fit 31.8mm or 35mm bars.

That covers the vast majority of new and recent bikes, but not quite all. Ravemen are not alone in ignoring old-school 25.4mm and 22mm bars though.

Value

At £199.99 this isn’t the cheapest light out there – Ravemen itself does plenty of far cheaper lights – but then it’s one of the most powerful lights around, and contains on of the biggest batteries.

One of the first things to ask yourself is if you really need this much… well, everything. For road and even pitch-black gravel riding, Ravemen’s own PR1400 USB Rechargeable DuaLens Front Light with Remote is still very bright, and it’s getting on for half the price (and 75g less weight) at £109.99.

The Ravemen K1800 is even brighter, also comes with a remote and really is half the price at £99.99. It’s also almost 100g lighter at 220g.

If you really do need 2,000+ lumens, the Magicshine Allty 2500 is considerably cheaper at £119.99. However, while it’s possible it’s been successfully tweaked in the last two years, the 2024 version we reviewed had some issues with overheating and an unreliable screen.

The NiteRider Lumina Max 2500 also puts out 2,500 lumens, and it’s slightly more expensive at £220. While our reviewer thought it was a bit heavy, it’s actually lighter than this Ravemen, and gives a good beam pattern. NiteRider has no UK distributor, however, so it’s a little harder to get hold of.

Overall

I really enjoyed the Ravemen PR2400. When tested to the max, its brightness and sheer reach are excellent. However, more practically on a day to day basis, its middle modes are very effective, with the extra large battery offering superb run times. With a clear screen and easy charge management, it’s impressively practical for something so fundamentally extreme.

9/10
Rate the product for performance when used for its designed purpose (1-10):
9/10

Any further comments on performance?:

The Road mode beam is excellent, while MTB mode’s full beam acts like a floodlight to spread light far and wide.

Rate the product for value (1-10):

Rate the light for design and ease of use. How simple was the light to use?
9/10
Rate the light for the design and usability of the clamping system/s:
8/10

Any further comments on the clamp?:

The mount works very well, though like many it only fits 31.8mm and 35mm bars. That covers the vast majority of new and recent bikes, but it’s too large for old school 25.4mm or 22.2mm bars.

Does the light have a waterproofing rating? If so, what is it?:

IPX8

Rate the light for waterproofing. How did it stand up to the elements?
9/10
Rate the light for battery life. How long did it last? How long did it take to recharge?
9/10

Any further comments on battery life and recharging?:

On full power this can last 90 minutes. However, I mostly used it on the road 500 or 900 lumen modes, which gave me three weeks of commuting. The LED display is great as it lets you know when you need a charge.

Any issues with durability?:

No issues except one day at work when I couldn’t get the light to recharge, despite trying three different chargers. The following day it worked fine. A strange one-off, then; I would be worried if I saw repeat examples.

Rate the light for weight:
7/10

Any further comments on weight?:

This is a bit of a beast because of its battery size, but it’s not trying to be lightweight.

Did you enjoy using the product? Yes

Use this box to explain your overall score

This is a very good light for both on and off road cycling. The LED screen and remote control are really practical, and the large battery avoids the need to constantly recharge. It’s quite heavy and not that cheap, however, and it’s probably overkill for a lot of riders.

Overall rating: 8/10
