A while back I got an amazing deal on a 15k 150w MH bulb for $15. I got it and it worked fine and it seemed like it was 6k. But i delt with it and then i got an algae growth. so i got a 20k 150w MH bulb for $20 and guess what? it started dimming after a month i got it. soo dim i could see the electric arc inside the bulb. I dont know why thses bulbs are soo cheap but there crappy! So now im ordering a Pheonix 150w 14k bulb for a good price of $60. A real reef bulb! Does anyone know why these cheap bulbs are so cheap? They stated they where new.
