DIY 250w MBF & MBI Gearbox V2.0
Decided I may as well re-house the 250w MBF gear that I used to have in a project box that I knocked up a while ago.
Tbh I was never really happy with those and I just have the 250w SON gear left to do. That will cover the "big four" anyway.

It's the same deal here, I have added a Philips SI51 ignitor to the circuit which is triggered by a non-latching toggle switch so I can use metal halide lamps which are designed for use on a mercury ballast.

That non latching toggle switch is a good idea

I'd like to be able to say that I could make something as nice as this but I'd be lying! Laughing
