I purchased both these bulbs a couple of weeks ago and have fired them twice. Once to see color without actinics and once to see color with actinics for a total of about 2 hours on them. These bulbs are the ones that are known as the "Par Buster" which during tests have tested very similar to some 250w bulbs.
Here is a link to
Sanjay Joshi's test conducted on various 175w bulbs. The bulb has been reintroduced as a 15k, but it is the same bulb as the Iwasaki 14k aqua2 in the test.

If anyone is interested I'll sell both together for 150$. They were purchased at 90$ each.
I'm looking for local pickup only but will ship for additional shipping fee.
Thank you,
Chris
