I knew if I posted I would find some charts. So much for the 150,s. Only half the Iwasaki. The 175 also out performs most 14K single ended, unless overdriven.
If going 250, the SA 10K seems to be the best par for the buck, even when driven with a magnetic ballast.
However I dont think its enough to make sense to run 250 watts instead of 175 watts. I would hazzard a guess the Iwasaki 15K and the SA 10K would be similar in colour ?
Only the possibility of running a different bulb would make the 250 a better buy?
Ok, done talking with myself. Guess I answered, the question.
