@jda is right somehow 20 years ago i was happy with my 175w Iwaki MH and corals was groin was nice (to my eye) than i jump to the LED mania build lot of DIY LED spend lot of money on tax and border tax,because in Canada you could not buy staff like in the US. After a time bought expensive original factory build LED i still was not happy,and corals was not happy.Someone told me you need different type of LED so i went to buy more expensive LED from different company.Same thing was not happy and corals was not happy.No i back to HO T5 am almost happy but still think about the good old MH it was simple and give something to the corals what they need.
