So I got an email back from the Bysen LED people, who are making the Helios look a like. The lady basically said in broken English type "for the exact chip model, ourRaw material director said it's a secret unless the customer had ordered our lights or are selling our item in their marke" Which of course makes one a bit weary!!! However she did say this "For helios series light, in the centre of each cluster 460nm:630nm= 1:7 we use cree led as lighting source and around 660nm:470nm:640nm:440nm=6:2:2:2 we use epistar led as lighting source" which attests to them trying to copy the Helios Basic spectrum that is posted on their web site that. She quoted me prices that are 1/3 that of Helios...Only problem is I have never even seen anyone saying that they ran a Helios grow. So it goes!!!
