I think both Dave
There are about 10 of us in the club with them and im sure alot more in EPIC and MAD with them and they work great.... For light output they are hard to beat without spending €250+ quid..! Build quality is grand too, i know fergal had an issue with the batt leads rusting at the connection point to the batt.... This can be solved, by a bit of sealer....or dont go out in the rain
I have never killed the batt on a nite spin, so you can get up to 3hours light, more if you turn it down to the lower setting on the fireroads...etc
I havent heard of anyone with the triple shot light yet...
For the price they are hard to beat....Even if you just get one winter out of them... You might have to do some messing about with the helmet mounting, but other than that they are grand...
Look them up on youtube, there are loads of videos..... search "magic shine bike light"
