replacement blubs MH

[robrich342]

I have current 150w 10'000k blubs now that need to be replaced. I was wondering If Hamilton or ushio are worth the money? which is the best and what should I buy 10,000 or 20,000?

Whats the best place to buy them?

I like the XM 10k lamps. High PAR value without the yellow tinge.
