The Magicshine MJ-902 is a good front and rear light combination that is ideal for longer-distance commuting away from city lights, with decent run-times and easy operation. It's not as bright as claimed, though it's still plenty bright enough for dark country lane riding, but having to cycle through 'off' to get back to full power is a bit of a let-down at this price.
The MJ-902 consists of a very compact front light with four modes (three steady, one flash), a tiny rear light, a battery pack and a remote button. The 5.2Ah 7.4V battery pack provides a massive 2,000-lumen output via two Cree XM-L2 LEDs and a claimed run-time of 3.2 hours in the brightest setting, over 12 hours in its lowest. I got closer to 4 hours with the front light, so it surpassed expectations in that respect.
Our Beam Comparison test (see below) shows that the light doesn't actually achieve the claimed 2,000-lumen output. Still, in use it's undeniably a bright light and easily forges a clear path in the murky darkness and helps you to pick out hazards such as potholes and patches of gravel. While it's short on claimed output, it makes use of the available output well, with a beam pattern that is generously wide and far-reaching in depth.
Fitting the lights to the bike is easy. The battery pack can be strapped to the top tube with soft straps that do not ruin your paintwork, and the lights attach to the seatpost and handlebar with rubber O-rings. During use, the lights stayed put and the front light didn't bounce around at all.
The system doesn't add much weight to the bike. The battery weighs about 300g and the front light is just 60g. But it does look a bit messy, with cables snaking around the top tube – one good reason for choosing a cable-free setup – though there's also a benefit to not having all that weight and bulk on the handlebar.
Rather unusually, the lights come with a remote control. This could come in handy if you were using the light on a helmet for off-road cycling, as you could control it from the handlebar. I used it, but decided it wasn't necessary as it's another button on the handlebar when there's already one on top of the light, and didn't use it for the remainder of the test.
The front light offers three steady modes: 100%, 50% and 30% and a flashing mode. The top rubber button cycles through the modes, but to cycle through the three steady modes you have to go through the flash and off modes – not ideal, especially when riding through dark country lanes and alternating between maximum output for descents and dimming for oncoming traffic. Being plunged into darkness isn't much fun when you're cycling through the modes back to maximum. (I always run two lights, so less of a problem than it could have been – but as with the BBB Strike that Jez tested, it's a weak point in a modern light.)
The 50% output mode is generous enough for steady speed commuting on familiar roads; I found I could pretty much leave it in that one setting for the majority of the time. (And avoid being plunged into darkness...)
The rear light similarly offers several modes and is extraordinarily bright, and because it's so small it's easy to find space on the seatpost or even seatstay. A top mounted rubber button switches through the various modes.
I've been using the lights for evening training and the 60km trip to the office, and the Magicshine has put in a decent performance. It's been reliable and has dealt with being caked in mud and blasted with water, both from the sky and hose pipe.
Its biggest attraction is offering a complete system with a front and rear light powered off the same battery. For regular commuting with lots of country roads and lanes this is a bonus, as you only have to worry about charging a single battery. While it's not as bright as claimed, it's clearly bright enough, and the beam pattern makes it a very useable light – especially if you don't have to change modes.
Decent run-times and good value for money for commuting and audax/touring, but not as bright as claimed

Make and model: Magicshine MJ-902 2000 lumen bike light combo
Size tested: n/a
Tell us what the light set is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Magicshine says: "Another new front bike light introduced by Magicshine in 2015 - 2000 lumens provided in a small neat little lighthead with the standard 20 degree beam pattern. The maximum output of 2000 lumens is powered by 2 CREE XM-L2 LED's. The light can be operated by the 2.4G wireless remote control button or of course the button located on top of the light head. The 5.2Ah 7.4V battery comes in a new, neat, low profile design which attaches to your frame with nylon straps in two places for a sturdy fit. The rear light is attached using the standard 'o' ring system, as does the front light, however the 'o' rings have been redesigned to fit two sizes of bar in one."

Good generally, but having to cycle through 'off' is less than ideal.
Deliver the stated run time with capacity to spare.
If you need a bright front and rear light for winter riding or commuting, this is a really good setup. I'm prepared to overlook the lack of claimed brightness but that might put some people off if they really want the full 2000 lumens.
Tell us how the lights performed overall when used for their designed purpose
Easy to set up and delivers reliable performance.
Tell us what you particularly liked about the lights
Easy to fit and use.
Tell us what you particularly disliked about the lights
The light mode operation could be more practical for those times when you want to switch between the three steady modes.

Despite not being as bright as claimed, it's bright enough for countryside riding and commuting and provides a decent run time. We've criticised other 'see by' lights that require cycling through 'off' and it's a definite flaw in a £100 light, though I found the middle setting ideal and just stuck to that, which got round the problem (I always use two lights as well).
