Yes that is correct.
I installed a BLF17DD in my BLF X6 a short while ago, and it is a big improvement to the stock driver, you absolutely don’t have to worry about it getting to hot, plenty (including me 
are looking to use the BLF X6 for triple & quads set ups, so it can take a single, no problems.
It is the same guy how makes the needed spacers for the triple & quad who did this giveaway, so pick up an extra spacer for a future upgrade because they will probably not be available forever, and I suspect that when you see your X6 with the A17DD-S08 in it, you are going to want even more
And with this driver already installed all you need is a triple noctigon mcpcb with some XP-L’s installed and the spacer+the cute-3 optic & BAM almost 3 times more lumens :bigsmile:
