Took possession of my new MJ816 1400 Lumen front light at the weekend, and after switching it on in the garden in total blackness i was very very impressed with the brightness and sharpness of the light levels and thought it would be perfect for the dark 15 mile commutes on the tow path.

I was eager to give it a proper test run, and today was the first opportunity i had. Set them up last night at home, butchering an old water bottle to house the battery pack,to give it a bit of waterproofing. Was a bit concerned by the tightness of the seal O-ring to the bars but it felt sturdy enough, but i was mindfil it was far from perfect. You get 3 O-rings to choose the best fit and i'd got it the tightest i could.

So i set off this morning in spitting rain and was full of "wow" as to how bright the light was on the road. Even with street lighting, you could tell the differnece.

I have a mile and a half before i got to the tow path, and as soon as i came off the surfaced road, straight away i kept having to adjust the position of the lights as they were constantly moving. Not by very much, but the first few miles of the canal whilst not tarmac are a lot smoother than the latter section.

Sure enough by the time i hit a cobbled section, they were either slipping down or back completely which ended up taking away all the light,and rendering the lights uselss. First time it happened, hit a pot hole, light dropped down and BOOM, front wheel hit a raised stone and i was down. Cracked knee on a rock, ripped leg warmers and lots of swearing. Re-mount, adjust lights, clip in and set off again. Blow me, 200m down the track exactly the same happened with the lights just slipping off the bars and this time wheel got caught in a rut and i have a badly grazed elbow as well as a ripped arm on my waterproof jacket.

By now it was sheeting down making the path very slippery, i.e. exactly when you want your lights to show the way, so as you can imagine i was utterly peed off with my new purchase.

If i can get home safely tonight i might have to make a few DIY improvements to try and keep the light more secure,possibly trying a smaller O-ring or using a bit of double sided sticky adhesive ribber strip, but unless i can do this i'm afraid the light is a waste of time.

The light levels are awesome, and i can imagine for road conditions they'd be just the ticket, but for off road or lumpy conditions, first impressions are i'm not impressed.

I let you know how my home improvements get on!

 
Mount the light UNDER the bars.

The little mickey mouse ears on this light really are stupid - would have been better with the 808 and a secondary light as a backup (which is best practice).

I use my 808 off road too and even if it does slip slightly etc I have been on rough crap and it's been fine. I use the SMALLEST o ring with OS bars - must suck on 26mm bars etc.


If you don't like the mount (don't assume its a cheap mount - its a Lupine system) look at modifying it to a Mawri mount which is a favourite.

Sorry to hear about your little falls this morning.. im looking at getting these lights myself once they come back in stock again as i've heard nothing but good reports about them.. sounds like its merely the fitting on the bars though so hopefully either using a smaller o ring or a little bit of packing under the current o ring should tighten the tension up enough to keep the lights in place..
but apart from the falls good to hear you say the light levels are very impressive... keep us posted of your mod...

Have a look at this link to another forum, there are instructions to easily attach the MagicShine to a handlebar clamp that can be bought for a couple of quid.

long term i'm going to do that mod, but in the meantime, i have progress to report. The problems are that the light and bars present 2 smooth surfaces against each other. That and my bars are standard 26mm bars.

However, i've stuck a thick rubber strip to the bars and then clamped the light to the rubber strip. This has worked a treat and me and the light have made up again!
 
I use the smallest ring on OS bars and it moves - doesn't your light have a rubber base on it though? Might be worth using one of them rubber shims in the meanwhile (as you have done) and a shorter band (or using the longer one and doubling it up).

yep, i also use the smallest O-ring.

The base of the light is a corrugated finish. It's not metalic, and it could be rubber i guess, but that alone does not provide any form of grip on the bars.

To me, the lilght is of no use whatsoever without the rubber shim between light and bars. Fortunately this was an easy mod, and the light output of the unit is very impressive.

Hi Paul,

I've got the same problem with my light. What sort of rubber strip did you use to sort this out?

Cheers

Hi Chris,

I just used a piece of rubber i had lieing about. I'm guessing it's 4 or 5mm thick and i just cut it into a strip to fit under the body of the lamp.

I also bought one of the clamps in the bike rader link above in post #5. This is excellent, and much better than the o-rings.

2 1/2 years on, the light is still excellent. The battery life has dropped away a bit though, but long enough to get me into work and back.

I have had a magicshine light for a few years now and never had any issues with the light moving about, it gets used on two modern road bikes and a 70's racer with slim handlebars.

You need to hang the light under the bars and it will then stay put. It also looks much better this way and it is very easy to move the head unit about in this position to switch between country lane riding and main road riding where it needs to point down a bit more.

Cheers Paul,

Magicshine have recommended a clamp off Ebay ...

But the one from Hope on CRC looks to be cheaper so I may go for that.

Or try hanging it underneath my bars!

Cheers guys
