XML Bike Light Useage Instructions

Mounting the Light Head to your Bicycle

The light head can be mounted to your handlebars (or optional helmet mount) using one of the supplied  O-rings. Connect the o-ring to the front of the mount, place the light in the desired location on the handlebar, and stretch the o-ring to the rear of the mount.

 Attaching the Battery

To provide you with the most flexible mounting choices, the  light set comes with more than 4 feet of cable from the battery and light head. This enables you to mount the battery almost anywhere on your bike. Wherever you choose to mount the light, be sure that it does not interfere with safe operation of your bike. You also need to secure any excess wire between the battery and light head so that it cannot become caught in your front wheel or otherwise interfere with riding your bike safely.

 Connecting the Battery to the Light Head

Plug the connector together. Be sure that it is completely connected to seal out dust and moisture.

 Charging the Battery

The battery  is shipped approx 50%  charged and although it can be used straight away it is best to  be fully charged prior to use.


To charge your battery, simply connect the charger to the battery and plug it into the wall. A completely depleted battery will take approximately 6 hours to recharge. The charger and battery both contain circuitry that works together to ensure that your battery is completely charged. Once charged, the light on the charger will change from red to green. Lithium-ion battery packs do require some special care. Please be sure to read the section titled “Care and Caution” for more information.

 Turning on the Light

To use your new light, simply press the waterproof switch on the back of the light head. The light comes with 4 modes, and pressing the switch additional times will cycle through these modes:

First press - Full brightness (about 3 hours of run time)

Second press - 50% brightness (about 6 hours of run time)

Third press - 10% brightness (more than 10 hours of run time)

Fourth press - Flashing mode (about 6 hours of run time)

Fifth press – Off

 Adjusting the Angle of the Light

The light mount is very secure but can be adjusted up or down to project the beam the desired distance from your bike. To make this adjustment, simply twist the light head on the handlebar until you are satisfied with the location of the beam. Please do not attempt to adjust the light while in motion! Doing so could cause you to lose control of your bike and result in a crash.

Just got my Lezyne 1500xxl back from Mark at MTB and it’s Brilliant! Better than original and the service and price was 1st rate.
If your light is running out quick and taking an age to charge it’s likely it needs new batteries.
Give this company a try.
5 stars all the way

Just received my luminator 18 mtb batteries light this time for my handle bars , this combined with the 800 on my helmet is a fantastic light combination .
Can't rate these lights highly enough for price and operation

Fantastic product. Ordered online, arrived within days. Great out on the trail and found it to be brighter than my mates lights which were twice as expensive - Luminator 18 bundle.

Love my lumen 800, it arrived really soon after ordering. Small, light and great quality. Fits neatly on my helmet and it's my trusty partner on solo nighttime adventures.

Great service from Mark, got a moon battery re-cell’d that wasn’t holding a long charge. Also ordered the lumen 800 to run alongside my lumenator 18. Very reasonable prices and fast turnaround.

"Great lights came in 4th on the Snowdownhill Gersau 2012, Rigi - Switzerland Team NANDROLON 2RADTUNING says Thank You!!!"


"I bought a set of your lights last week. I used them on a solo non stop ride of the West Highland Way starting on Friday night and they were great. Even on low they were fine for cruising along, so I was easily able to manage the 9 hours of night riding without the battery getting near low. On full power the performance is fantastic, the balance between beam and peripheral seems right to me. It also rained almost non stop and the lights weren't affected at all. The quality of the construction, cables and sealing all look really good and it definitely stood up to the test. Great product at a bargain price.
Best regards,
Tom D"


"Another good service experience here, ordered Tuesday 0950, in my hands at 1030 this morning; well done to both Mr Smudge and Royal Mail! "


"I ordered a V2 XML light off Smudge on sunday and received it today tuesday bloody hell that was quick and he also told me via facebook it was on its way

All the praise heaped on Smudge is well deserved"


“Having 4 friends with your V1 XML light, I finally gave in to the need for more light and was fortunate enough to time it just right with the V2 coming out.
My 'V2' XML Light arrived this morning. Super fast delivery - thanks!
I thought my old light was good but this is an amazing amount of light for the money and seems to be well built and very robust.

Thanks for the great service.


"I really appreciate the stellar customer service. That's really hard to come by these days. I tell everyone I know about those lights, as I think they're absolutely brilliant!"

Cheers, Andy
