AH Supply service
I started with a 55w kit over my 29 and it was great so I went with a 2x55w kit for my 55. I wired it up, installed the bulbs and fired it up. I noticed the bulbs were awfully blue, so I checked the temperature. They were 6700K instead of the 5400Ks I ordered. I notified Kim of this via email. He quickly responded and arranged for an exchange including reimbursement for shipping back to him for the 6700Ks. I contacted him last Friday afternoon and I got the bulbs today. The 5400Ks are absolutely perfect for a planted tank. I've tried 6700K, 9325K, 10000K and 50/50s as well, but the 5400Ks really stand out.
