I thought about it for a while before taking the plunge, choosing only to go with the LED upgrade as i didnt want to mess with the battery life which is a big plus point for me. With mine being from 2007 they were claiming quite a big improvement with just the LED upgrade anyway.
Turnaround was exactly 2 weeks, as promised.
Performance wise, to my very uneducated eye they are certainly brighter however i didnt do any beam shots before i sent them off, so i’ve only got a comparison with a Bastid light to go on. An individual lightset is now a match for the Bastid and with the 2 sets on they’re much brighter.
All in i think its a good upgrade to make.
