The right one is for MBF ballast + 750V parallel ignitor and the rest are for SON gear.

These will be on MBF gear, with superimposed ignitor, the GE Kolorarc runs a beautiful warm colour on this Parmar ballast Cool

But I think the GE Kolorarc is for SON gear (The CMH for sure). Underdriving a MH lamp, causes more liquid halides which can corrose the arctube.

The Kolorarcs are usually for SON gear yes, however the original MBI version of it was designed for duel gear, but the normal 'default' gear in the uk for 250/400 halide has always been mercury, more or less every, lowbay, flood, industrial uplighter for halide lamps that you bought here came supplied with mercury gear and all types of halide have been run for years like this Cool
