Do Phoenix Bulbs Measure Up?
I am currently running 20K AB bulbs, I love the blue but I want more growth. I am looking at either the Phoenix 14000K or the Giesemann 14500K. I can just about buy three of the Phoenix for the price of two Giesemann. What makes Giesemann so much more expensive? The Phoenix seems to be very popular, are they any good, or just a cheap bulb?
