T5 and or MH are still the best light for sps.
you could try a fixture that has both T5 and LED maybe? the reasons because I have seen a lot of sps folks going back to T5 or MH after trying out LED for over 10 months. However there are a few that do have good success with using LED on acro but a few though.
For a light to be considered successfully, it needs to give us both good growth and nice color .
A lot of folks in here sometimes they tell you that their led have no problems with acro but they dont realize that they have not been using it long enough to know.
A lot of folks will recommend their LED light as the best or good light, some even say they could not live without it or will never look back...when that is the only LED light that they have ever used/tried or could afford.
I am somewhat considered myself as an acro sps person. I have tried Ecotech Radion and Rapid DIY led for over a year but eventually gone back to older technology light in T5.
