10k CMH finishing bulb??

Anyone have any experience with these? Thinking of picking 2 up here in a few weeks.... Everything I have read up on these bulbs make sense and would seem to be worth the investment. But I can't seem to find many reviews or first hand account of individuals using them! So if anyone here has I would love to hear about it! Thanks!!

i use 4200k veg 3100 or 3000k flower and 10000k finish
