The Magicshine MJ-858 bike light is the replacement light for the discontinued much loved MJ-808, developed in 2015 it has proved to be our most popular light ever! Reliable, compact design, with a fabulous 1000 lumens beam, the low price makes this a light thats hard to ignore. Reviewed in January 2015 by road.c.c. scoring a massive 4.5 out of 5 stars. PLEASE NOTE   Since theRoad CC review the battery has been upgraded with a 4.4Ah battery as standard.  We also give you the option to upgrade the battery to a 7.8Ah almost doubling the run time on full power.  However - I think the best battery is the 4.4Ah, small compact and gives at least 3 hours run time.   


If you haven't got much bar space left, have a look at the MJ-858. With a diameter of 3.2cm and length 4.5cm this is a diminutive light that stores away easily into pockets or small bags without a problem. Total weight is 147gm including the battery bag.


The tried and tested Magicshine 'O' ring mounting system continues to win plaudits for its robustness as well as ease and speed of use. With a choice of two 'O' rings for different size bars, mounting this light is easy to do within seconds. It's clean and easy, ideal for commuters.


The standard battery is a 4 X 18650 cell 4.4Ah battery. With a fully sealed plastic cover and rubber straps to enable you to fix the battery to your bike without the need for a battery bag, it offers excellent protection against the elements. We're also offering this model with an upgrade to the 7.8Ah battery incase you require some extra run time.  Please choose from the options available.   


This is a barrel shaped design, black T6 Aluminium alloy. The inner case has cooling fins along it's length while the outer shell offers further cooling ensures a cool touch to the hand. 

In Use 

The MJ-858 continues the Magicshine reputation for ease of use. The single click switch at the rear of the light controls both on/ff and beam functions and it really is simple to use. Clicking the switch brings on in turn high beam, low beam and flash modes. The rear switch has 5 colour modes to warn of reducing battery power. Green, blue yellow red and finally flashing red (<5%) give adequate warning of impending power loss.

Run Time 

The MJ-858 will run for 3.5 hours on full brightness with it's 4.4Ah battery, you can easily extend this by reducing the output.  However if run time is parramount to your requirements, then just upgrade to the bigger 6.6Ah battery to get well over 5 hours run time on full power. 


The MJ-858 uses a single CREE XM-L2 LED. It packs a punchy beam of 1000 lumens, comparable to the MJ-808E. However we tested both lights together and the MJ-858 has a brighter beam with significantly less halo effect than the MJ-808E. The brightness is evident in the beam spread which offers more of a flood beam than the MJ808E although in our judgement, beam length was similar. 


The factory offers a 12 month warranty on the light head, 180 days on the battery. However Bonita likes to do things a little bit differently and as usual we therefore offer a 12 month warranty on all components, including the battery. Another reason to buy from Magicshine UK.


Bonita says

The MJ-858 is certainly our most popular light ever, it's the reliability that stands out most for us.  Priced at just £59.95 you really can't go wrong with this light.

  1. Great lights. Compact, easy to fit and operate. Good battery life. Review by Sean

    I bought two for using on my 25 mile commute on dark rural lanes. One light would do the job but a second acts as a good backup. The 4.4Ah batteries are reasonably small and the flexible mounting is easy to get on and off. I attach mine to the underside of the handlebars either side of the stem. Lights are also easy to fit and the large button makes them easy to operate. No problems with battery life. In -5 degrees recently they went to blue mode after about 40 mins and stay there for the remaining hour of my trip. So plenty of life in the battery, even in sub-zero conditions.

  2. Excellent light with superb customer service has made me very happy. Review by Barry

    This is a truly fantastic light made to the highest quality. Comes in very nice packaging with everything you need inside. The light output is superb with a really good lens to harness the light. The run time is really exceptional for such a powerful light and I purchased the 6.6Ah upgrade battery at the same time as I like the option of always having a fully charged battery when the other needs charging and the higher capacity battery will be useful when we go on extended rides particularly as the winter nights are upon us.

    I have to comment on the customer service which was particularly good and gave me confidence that I'd made the right choice. The helpline really could not have been more helpful and they bent over backwards to deal with my queries.

    Overall I'm very happy. (Posted on 12/10/2016)

  4. Serious Oomph that won't break the bank Review by Hannah - Total Womens Cycling

    The MagicShine MJ-858 bicycle light is a great option for those looking for a commuter light with some serious oomph that won’t break the bank.

    Opening the box initially I was a little wary – inside sat the light head, two rubber O-rings, a charger and battery pack. But once I took them out I was thankful to find that set up couldn’t have been easier.

    The small yet mighty 1000 lumen light attaches to your handlebars with the handy rubber O-ring. An ample sized button sits on the back of the light that controls the three settings – full, dimmed and blinkered. And I am happy to report that the button is easily managed in winter gloves.

    The light then attaches to a 4.4AH four cell battery pack which can be fixed on the crossbar, downtube, top tube or seat tube – really wherever you see fit. The battery pack is attached using two flexible rubber straps.
    If you are someone who locks their bike outside and constantly needs to pop lights on and off your bike then this light might not be your ideal option. But for those who have an indoor lock up and ride through dimly lit streets to work it is perfect.

    At full whack the light lasted just over three hours but at the lower setting I was happy to find it lasted just over 10 hours. So no need to charge the light every day which is good for someone who tends to be on the go from day to day. My only gripe with the battery is the fact that it needs to be connect to a wall outlet, I do find USB charging lights preferable for day to day commuting.

    All in all, this light performed brilliantly all round and was pretty impressive given the £60 price tag. It is far better than other lights in this category with far greater price tags. The 12 month warranty is a further bonus!

    RRP: £59.95

  5. Excellent update from a smaller cheaper package Review by Road.CC

    Check out this excellent review from none other than Road.CC, in fact one look at the light comparator in widescreen will have you buying in bulk. (Posted on 03/03/2015)

  6. Budget Price, Outstanding Quality, Super Bright! Review by XCRider

    A very small and very powerful light! The flood beam is brilliant, so good I bought another to mount onto my helmet for extra versatility! (Posted on 16/01/2015)

  7. Small, bright and well made Review by NewtonUK

    I put the MJ-858 on my handlebars and it practically disappeared, the thing is small! However, the power button is easily accessible with full gloves on!

    I'm still working on where to locate the external battery pack, which is also surprisingly small. Hopefully it will be of sufficient capacity to last for a full week's worth of commuting.

    First impressions... Great little package with a bright light! (Posted on 19/11/2014)
