looked like the cointaker variety to me. Probably be a load of #45-47 bayonet fitment type for the General illumination. (in blue of course)
Cointaker leds are ok(ish). The bayonet type are fine, but the insert type from them are crap as they fall out of the holders after a few games. I tend to buy mine from Albert Medaillon. He was supposed to be there at the show, but i didnt see him on saturday. Shame really, i wanted a few myself.
