I dont lnow if anyone has tried an Avici Led ?, but I have one ! I can dial any spectrum in ( hps ,mh , cmh , anything at all) & lower the wstts from 28 watts to 1150 watts. These Micro Revolution "Avici " Ledsare amazing. I dont think there is a better Led out there. I would like to hear from anyone else that has one. Believe me they are amazing. I threw my cmhs out after I put my "Avici " up !!! There eas no comparison to my hps & cmh lights. I did not think Leds were any good until I tried the "Avici " Led !!! Other Leds have no chance coming close to these amazing lights !! I would advise everyone to try to get a few of these kick ass lights ! Keep on Blooming !!!
