Very interesting - only problem is they cover 175 and above, so nothing for the 150's - I do see there are some for 150, here:

if this works out, I may have the Seahorse get some in from J&L or HR - If the above one works, it's a great price (under 50 bucks) even if it only works for a few months - and then I can test out the 14k spectrum!
Now - the question is - will this work with the Aqualight Pro ballast?
