Magicshine MJ-908 8000 Lumen LED Bike Headlight Review

Thanks for tuning in this is The Sweet Cyclists and today we’re gonna be reviewing the Magicshine MJ-908 this is an 8,000 lumen bicycle LED headlight. [Music] Alright so here we have the packaging for the MJ-908, this is Magicshine’s brightest headlight rated out of theoretical 8000 lumens. If we go ahead and open the packaging, you can see you there is a tail light, headlight, battery and the wall charger. Let’s go ahead and take the headlight off. It’s rated at 8,000 theoretical lumens and consists of eight Cree LEDs. Each LED is theoretically rated at a thousand lumens or a little bit more, so overall the light ends up being 8,000 theoretical lumens. Whether the actual output is that or not… we’ll get to that later in the review. You can see this is a large light, and you get some really nice features. Note the this light uses the four pin orange plug, so if you have other Magicshine lights you should be aware that these plugs aren’t always compatible. You get an LED display on top that tells you the run time and current mode which is a really nice feature. Lets go ahead and look the tail light, this is a standard 15 lumen red LED tail light. It’s pretty nice, and comes with a basic rubber strap. Note that I do have to warn you though, the wiring with these are a bit messy for a road bike. You end up with a lot of wires running everywhere. You also get the normal 6-cell lithium-ion battery, it is a large unit but I really like these batteries. These are their improved battery designs, especially if you’ve used some of the older Magicshines. The battery pack is well designed and fully enclosed, so you can’t actually replace the individual cells. There are nice rubberized straps on the bttom and more than a power to take you through a week or so. Again notice the orange plug that makes it not compatible with some other Magicshine lights. You also get a wireless remote, I’m not quite sure why they include these. It’s kind of nice if you’re running the tail light, because I’ll let you use this button to turn the tail light on/off and the front button turns the light head unit on/off. You get a normal wall charger, these are pretty standard if you have one or two Magicshine lights by now you probably have quite a few of these. The chargers have a LED indicator here, that goes from red to green once it s fully charged with this kit. You also get a splitter, these are pretty nice if you want to run both the taillight and headlight. The splitter connects the battery and headlight/taillight plugs with the orange plug for the battery. The organge plug has keys so it can only be inserted in one direction. One annoying part about wiring is that if you run the battery on the toptube the headlight and taillight wiring run toward the front of the bike, and you’ll need to bend the taillight wiring around. That’s one reason I don’t use the tail light, as the wiring becomes messy on a road bike. You also get some different straps for different size handlebars. Overall really nice packaging with custom cut foam you can travel with if needed. Now let’s look at the fit and finish of the MJ-908, this is their top-tier headlight that currently sell with 8,000 theoretical lumens. It’s not clear whether you actually get 8,000 lumens but in the riding I’ve done I think it’s closer to about three or four thousand which is more than enough. There is a single button interface with a plastic body and aluminum fins. I think the coolest part about the light is the LCD display on top. This is a really nice feature as you don’t just have simple colors where you have to guess how much you battery you have left. You can see the screen alternates between remaining runtime and and the percentage battery left. On the top-left corner you see the current light mode, I’m currently on low and then a battery indicator on the top so really nice. You get a single button interface with this, which means you just click once to cycle through the modes and the flash mode. The flash mode is far too bright and a long click turns it off. It’s really nice to have actual real numbers instead of having to guess colors. It feels really well-constructed, but it is a big light. If we bring out the ruler you can see it’s close to 3 inches long and almost 2 inches tall. If we look at it’s younger brother, the MJ-906 which is a 5,000 lumen light you can see the MJ-908 is nothing more than a product an engineer would design. Everything’s bigger, you can see it’s about 50% from you 20-30% taller. It’s significantly longer so if you put them side-by-side you can see that the MJ-908 dwarfs the MJ-906. It’s so pretty interesting to have them side-by-side, this is really fits in the palm of your hand well this one really fills it up. Overall the design is very similar, the mounts a strong because of the heavier weight of the 8 LEDs but overall we like it. Although it has a higher price you get a higher output, and even though it might not be 8000 lumens it’s s almost too bright. I’ve definitely gotten yelled at by oncoming traffic even on low mode. Right now let’s take a look at the MJ-908 installed on my Specialized Roubaix. You can see here the light head is on the handlebar, it is a large light and takes up quite a bit of space. I have the wired battery pack installed on the top tube, and I’m not running the rear taillight because the wiring. With a road bike the wiring is a bit of a mess because you have to come out and turn around here. You can see with the light on, it’s very bright even in daytime and you get some side visibility through the little slot for extra visibility. I would recommend a different style mount because obviously takes up quite a bit of space. You can see the LCD display, which I think probably one of the best features. You can see runtime and current light mode. Let me go around to the front, you can see the light is really bright it’s a little exaggerated with the camera but even in daytime it’s pretty blinding, and the strobe mode particularly I wouldn’t recommend that doing doing that on kind of busy traffic. [Music] Alright now let’s take a look at the beam pattern at night. There are four different constant modes: we have low which is twenty percent we, medium which is fifty percent, medium high which is at 75 percent and then high which is 100 percent. They don’t actually publish the lumens for each mode, just a light percentage. Here we see the strobe mode which is pretty bright, it’s most likely a medium or medium high. The MJ-908 probably doesn’t put out 8000 lumens, but as you can see from the side by side photos it’s a extremely bright light. You can also see from the photos that the beam pattern is a mix between a flood and spot light, there’s quite excellent horizontal spread and vertical spread. Compared to other lights, the MJ-908 s the brightest light I’ve ridden with. In my experience I usually never go beyond the medium setting as there’s more than enough light. Now let’s go over the pros and cons, I think the first pro is the LCD display. You don’t have to guess about runtime or try to decipher different colors on the button. You see your runtime and the current mode, so that’s a really great feature. The other pro is there’s more than enough power to turn night in a day, the MJ-906 is extremely unnecessarily bright. Finally the beam pattern is really great, it’s got a lot of diffusion and flood, with more than enough throw to see far down the road. Some of the cons are the large form factor, it’s a tall light and the heat sinks in the back take up quite a bit of space on your handlebar. The other thing is that there’s no real cut off on the lens design, resulting in a blinding light for oncoming traffic. I recommend only using this light for off-roading or really dark roads with low traffic. Finally, advertising the light as a 8,000 theoretical lumen bike light is a little bit dishonest. It would be great if they actually published the actual output. It’s probably closer to four or five thousand lumens. Again it is a really bright light. Now that we’ve gone over the pros and cons, let’s give it a final rating. For the MJ-908 I’m going to give it a ten out of ten. This is really an absurdly powerful light that is not perfect and probably not 8,000 lumens. However, this light is bright and with eight LEDs built-in it’s really impressive.
