will their be v2.5 upgraded lux kit for those of us who have the gp v2.1 available?
If you mean the v2.5 switch, yes, it will be available as spare, a few days later the Lux batch. The locking ring solely cannot be compatible with the v2.1 switch base, because the threads are calibrated from now on and the tolerance level is 0,05 mm. The v2.5 switch is compatible with the tubes of the previous versions.
