I once had an ATI 6 bulbs (6X 54W= 324W) replaced by 2 black boxes (330W) and it was the worse move I've ever did in my life! You only can tell if you know better! Colony structure was absolutely terrible. The colors were only emphasized by the reflection of the blue diodes, while they were over the system. After about 6 months I replaced the LEDs by the same old T5s again. I then noticed the colonies actually changed/lost some of their natural pigments they had produced under T5s, while they were under those LEDs. After a week under T5s again they started to show an amazing transformation!! The electricity bill basically didn't change at all because I use chiller to maintain the temperature independent of what type of light I use. Went back to metal halides a while ago because I missed them so much and the results were obviously amazing. Reproduction, colors, colonial structure are even better than T5 only. Metal halides and T5s are the very best in captivity. The simplest test one can do is to offer a 150W LED fixture against a 150W halide bulb alone. The qualities of halides count, like spread (with the proper fixture), UV, IR and consistent spectrum, not PAR alone! Even a 20K halide bulb will explode of growth and colors against any "high PAR" LED fixture under the same circumstances!!! There is no comparison! Generally speaking LEDs are a fashion and market propaganda for a high priced tag product. An overpriced tag in most cases, to tell the truth. I'm glad your system is showing those amazing results! Happy for you!!! Heard nothing but great things about Hamilton fixtures, bulbs and customer service through the years! Watch your clams... they are in love with your halides!!! Right on!
