Once again 2100 your talking about a fry ray L1 not the TR-J12 
I did say i dont think we will see 7.5 amps at the tail cap, (so if its not at the tail cap where else would it not be) and i did say depending on the boost circuit of the driver (twice) but 7.5 amps works out at 1.5 amps per led, 2750 oft lumens aprox (i should of said emitter lumens), we dont know if the driver is buck or boost or buck + boost or nothing yet and i did say my current draws are just aprox math basicly quessing and i have not tested the torch yet and some of my post is speculation, like what most people are doing on this torch.
But we do know some things, the trustfire tripples seam to be more stable then the sky rays tripples, it is a nice looking torch body much better looking then the TR-3T6 with more cooling fins and either way it will be brighter then the TR-3T6, i personaly feel this will be way better then the fry ray 3 x T6 or 5 x T6 and it will be a great torch that will put out more light then you will ever need, unless its turned off.
Im confindent if its any thing like the TR-3T6 it will be half decent, i like the brand trustfire and all my multi cell trustfire lights are very well driven and regulated with good heat sinking, im very confident it will be a good flash light or i would not of droped $114.50 USD on the light some batteries for it just to try.
p,s i used Match's emitter test and DrJones LED spec plots to get a aprox otf reading, but there is many variables.
