Today I got power-meter from Bell Laser. Excellent speed on delivery.
Its surely nice to know how thins unbranded tube will perform.

Still miss my goggles, so I have plenty of time to get electrics updated to EU-spec.

Plan is to convert rear sockets to real EU-spec sockets and make separate switch board. Power to rear sockets will be taken before main switch, so basically machine key components electrics will not be touched by mod nor affected by use of rear connectors.
