Strengths:    This lights emit a very nice arc of light, side and frontal illumination there is absolutely no complaint there.

Weaknesses:    Mounting system is weak but usable. And at least you can quickly instal on and off if desired. But for trail riding with a lot a bumps, not so much.

Bottom Line:   
I purchased them mainly after reading a few really good reviews online. The price was really good, maybe too good. They initially work fine, battery lasted a good 2 hours +. But alternating brightness settings. On my 4th time using it, the battery started dying after about 30 min of use and at the cable connection juncture where power switch, battery and light meet there is an internal wire disconnect. This is a non serviceable sealed juncture, I ask customer service for a schematic so that I can fix/ solder myself but received no response to several emails.

Strengths:    Excellent beam pattern.
Lots of options to adjust the brightness and combination of lights used at one time.
Remote control is handy to use while riding.

Weaknesses:    O-Ring light head mounting system is weak sauce for a light of this size and configuration.
Over the years I used this light, I had several issues with the charger, wiring and plug.
Battery replaced on recall.

Bottom Line:   
The Good:

I used the heck out of this light over the four years I have owned it. The light itself, and especially, the pattern of the beam are great for trail riding at night. The flood bead is pretty wide and affords the rider good peripheral vision, and the spot isn't terribly harsh, which makes this light a pretty value for what it costs.

The amount of control available when you can separately dim the side floods or the larger spot, or both the flood and spot together, is a nice feature to have. I can leave the spot off, and dim the floods down pretty low and have a nice long lasting climbing light. Then, put all of them on the highest setting for high speed descending fun. It's even better if you have a spot beam on your helmet that is set to reach further down the trail, and to look around sharp bends.

The Not-So-Good:

The o-ring mounting system for the handlebars isn't sufficient for aggressive trail riding on bumpy trails. It either bounces so violently that it acts like a strobe light, or rotates forward/down so you can't see. For a while, I would use a few small zipties daisy-chained together in place of the o-ring, and put a wind or two of electrical tape on the bar, and that was fairly good at keeping the light in place while riding, but left something to be desired in terms of being user friendly. I also had a ziptie break a couple times while riding, and that was fun when all of your light suddenly disappears.

I eventually adapted a mount from a bar mount from an old Blackburn 6v halogen system I had from many years ago, and that mostly solved my handlebar mount issue, except it would only fit on the narrowest part of the bars. BUT, at least it was secure and didn't shake like a wet dog.

Eventually, the connector plug failed, and I replaced it with a plug from Radio Shack, but the wires are so thin, that they would eventually break away from the plug, and I would have to re-solder a new plug on there. Using some electrical tape for strain relief helped, but only for so long.

Then, the insulation that covered all of the wires began cracking and splitting in several places and I knew it was only a matter of time before the wiring would be the death of this dandy little bike light for using as a handlebar mounted light.

As for using the MJ-816 as a helmet light, it's a little heavy and tall to be enjoyably used while mounted on your head (helmet). And, the Magicshine helmet mount leaves plenty to be desired. It mounts the light head at the front of the helmet, which makes the helmet slide down onto your forehead. All-in-all, there are better helmet light solutions available than the MJ-816 IMHO.

It was a bit of a love/hate relationship with the MJ-816. It was a wonderful trail light when everything was functioning properly, but I never knew when it was going to fail in some way, or go into limp mode. I got four years of heavy use from it, so for the price, I can't complain too much.

Trying to find a suitable replacement at a similar price point has not proven easy. I would get anopther if not for the wiring/plug issues. I have a suitable mount, but I don't know if I could solve the wiring situation over the long haul. That wide flood feature was really nice, and I'm not finding an all-in-one solution without resorting to having to get two of them to get the beam wide enough.

I am finally trying to get away from having a separate battery type light, and I am finding that the all-in-one lights are generally designed for commuting, so the flood part of the beam doesn't have to be as wide as it does for high speed aggressive trail riding.

If you get this light for trail riding, I would add a little budget for some kind of more secure bar mount, and they are available here and there if you look for them, and use some imagination. I think the wiring will last long enough to more than get your money's worth, but it will likely fail eventually.

I would recommend the light, just know what the possible issues are, and be prepared to deal with them

Strengths:    This is for the MJ-816E -->1800 lumens

extremely bright, side lights are excellent for wide visibility, easy installation and operation. Great price.

Weaknesses:    battery seems kind of cheep but it is easy to mount in a water bottle frame against the down tube. The mounting system uses thick urethane bands. The light can become misaligned over a series of nasty bumps but are easily straightened out. Its not a major issue. and you don't have to have a mount on your bike when you remove it.

Bottom Line:   
On of the best choices I have made this year. I just hope customer service is ok if I have an issue.

Strengths:    Excellent beam.

Weaknesses:    Unnecessary large battery case that does not appear totally waterproof. Ridiculously cheap mounting system.

Bottom Line:   
What can not be said enough about this light is the perfect beam pattern that the two outside leds cast. Beam pattern is easily more important than total lumen output. For riding in traffic, the 800 lumen output of the two side leds with their wide angle lenses is all you need. For the trail, add the center and you are good to go.

As far as build quality, a few months ago I purchased the mj-856 for my wife and mounted to it a separate wide angle lens that magicshine sells, and she has used it without incident through wind and rain. I am hoping for the same.

In the end, some people may find it cumbersome to mount three separate things (light, switch, battery), which is way I imagine that magicshine is now placing all power switches on the light.

Strengths:    Great light output, great battery life, and great price.

Weaknesses:    None that i've found.

Bottom Line:   
Have not had any problems with mine. Everyone i rides with uses these lights and they haven't had problems either. There is of course the battery problems of a year ago, and they seem to have recently switched to internally circuited power for the smaller lights, so i imagine they had some problems at some point. However, for the price, they won't be beat.

Weaknesses:    Haven't found one yet...

Bottom Line:   
These lights are great. I truly recommend them. They flood good light towards the sides of the trail with the secondary bulbs. Use them with the MJ-808E and you will really get a good coverage on a pitch black night.

I work in product development and let me tell you that NO light in the market should be more than 300 USD. Up from here companies are making HUGE markups.

Strengths:    Cheap light. Bright. Really bright. To the point where cars drive in the other lane to avoid being blinded.

Weaknesses:    Cheap company. Quality. Self destructed almost immediately (about 8 uses and issues started after only 4). Water proofing of the light unit was only done of obvious areas like lenses. Non-existant customer service.

Bottom Line:   
Bought the light because of a few decent reviews though mostly because of the price. I was impressed at first the light was bright, had a pretty good beam pattern and ran quite a while on a charge. After about 4-5 uses it started acting odd. When turned on there was a shrill pitched and oscillating squeel coming from the light. I soon noticed that it was also dimming slightly in time with the oscillation at roughly 1/2 second intervals. Additionally the light also seemed to be throwing off all sorts of radiation when turned on as my wireless bike computer and GPS, as well as my TV would all go nuts when turned on. Having now read up on the battery problems of previous models I decided to test the battery and charger with my multimeter both of which measured within their listed voltages. After charging the battery again and trying the light the squeal turned into a shriek, then the button would only give the flashing red (battery almost dead) light. Shortly thereafter it died altogether. At this time I hunted the web for a solution for which there was none. Finally I ended up at MagicShine's page and after determining there is no service shop in my area as I am currently deployed to Okinawa with the Marines, I sent emails to the warranty department just describing the issue and asking what I should do. I did not demand anything I just asked for a course of action. As you must already suspect I was ignored.

Lets be honest bike lights do not really need to cost $600+ and run on refined unicorn tears, however a company with prices this low ($85) will get a lot of initial business from those who dont want to spend a months pay and their left kidney on a light. The issue is that they have two choices as to what kind of business they want to be: 1. Build a decent quality product. Perhaps not quite as nice as those $600 guys but decent and usable. Also offer good to great customer service. Which leads to a loyal/autopromoting customer base. Or 2. Build a cheap product fast and then ignore your customers when they ask you to fix the garbage product you sold. This leads to quick profits and an equally quick and inevitable business collapse Ala General Motors. I hope you are not expecting a Government bail-out Magicshine. Bottom line folks: Aviod this company they are out for a quick buck and will spend it on hyping their newest product rather than taking care of their customers. Thanks for nothing MagicShine...
