Current 150MH&130PC Bulb replacement help

[KAKLANGLEY]

I have a 48" current outer orbit 150MH with 130 watt PC and want to change the bulbs but cant find any thread about this. So I looked a Sanjay's site and I am more confused now. Looking to be between 10K and 15K with the highest PAR.

Any help would be greatly appreciated.
