"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
