Parmar 250 2.15A MH/HPMV

[MetalHalideHater]

Would I be able to connect a 35w SOX ballast in parallel to this (the Parmar)to boost the current up to run my 250w Powerstar HQI-E/D. Furthermore, could the reason my SON deluxe isn't as white as you describe because I'm underrruning it on th Parmar.
Thanks

Unfotunately Nope as the SOX Ballast is different than the MH/MBF Ballast, also the Lamp voltages are different example the 250w HPMV/MH runs at 130 volts whilst the 35w SOX runs at only 70 volts thus the Impedance would be out completely, the best solution is a 250w SON Ballast, or use a 100 and 150w SON Ballast in Parallel as the Lamp voltage is 100 volts for all three ratings.

If you are looking for a 250w SON Ballast there a few on E-bay for £20 plus £6 Postage see HERE

I got my recently acquired 250w ballast from the link listed in the above post. It is a BSN 250 L34.

Yes that is a GOOD ballast. Philips INDUSTRIAL range. Fully water proof and covered coil these really take the abuse!

Yes, I noticed how the whole thing had been potted in a nice hard plastic. F'kin heavy too!

Would I be able to Power a 50W Mercury Lamp from a 55W SOX Ballast??

Thanks Colin for that information. I have ran a 70w Metal halide lamp on a 70w SON and 35w SOX ballast and it gave off a much warmer light-overrunning it to around 100w I would say. I just didn't want to harm this lamp.
