Keep in mind that in my experience with MH bulbs that once the bulb gets older it loses a lot of its "blue" 14K look. When I changed out my last 14K bulb I went from a white to a very much white-blue. I had to check and make sure I didn't get a 20K bulb by mistake! I guess the reason I posted this was to give you a little warned that that a used 14K might not look the same as a new 14K
