I might have gotten a bit carried away. I left the FET driver, the BLF17DD, unrestricted. Luminus emitters have low Vf. This SBT-70 is no exception. With an AW IMR18350 it will pull over 11A for 1570 lumens. :bigsmile:
I smooth it down by using an Efest IMR18350 V1 flat top cell, at 6.76A and 1180 lumens. So far so good. 
Dale, do you think a TIR would yield a longer tighter beam in that set up? Oh, and also, 11A Holy Cow! I assume XML2 but what bin? How long until too hot for comfort?
BTW, are you feeling Ok? Only two pictures and less then half of the juicy details. Thats kinda weird.
The XM-L2 simply wonāt do 11A, the bond wires fry at or just over 8A.
This is the Luminus SBT-70. The only circular die that Iām aware of and one of the first āfactory de-domedā emitters, not having the typical silicone dome but instead having an AR coated glass lens covering it for protection. This is neat, itās what drew me to the emitter in the first place, but itās also a detriment.
Normally our reflectors or at leas the centering rings go on/around the emitter or itās substrate. With this large glass lens over the die, and an already large die substrate, this just isnāt really feasible, not in a small light anyway. So I had to cut the raised portion off the bottom of the tubular style reflector that Sinner uses in these lights to allow the die to be as close as possible to the opening in the reflector. I also had to fit the copper pill by widening the star opening, after cutting the 20mm MT-G2 Noctigon star down as much as was feasible. The Luminus is a huge emitter, bigger than the MT-G2 but conveniently overlapping the contacts enough to use the MT-G2 copper star.
Luminus emitters also have much lower Vf, allowing higher current rates. This one is rated for a max 10.5A, but obviously it wantās more. Iāve got a Luminus SST-90 in a C8 that pulls right at or slightly over 16A. They pull loads of amperage, but are not as good as Cree emitters at convering amps to light output, so they do get HOT! I figured this solid copper light would be a good candidate for such an emitter. If the switch can hold up. Working on Sinner to make me a new tailcap that can take a McClicky or MattAusās new SmartSwitch (not yet available) The light is just too small to use a Tofty. 
(Iām thinking about making a Tofty work, which would entail some crafty use of my rotary) As for now, Iām using a lesser cell for 6.76A and hoping the switch doesnāt cave.
I didnāt post loads of pics as well, this isnāt my thread. 
And Iām working on over 2000 pics from the last wedding, am, quite frankly, tiredā¦
Edit: FWIW, this emitter does 15.67A on a Sony C5 18650. The 11A is from an 18350. 
Sinner, I am looking to find a clip to hold your light in my pocket. What is the length of the 18350 copper? Also, if I sent you the clip, do you think you could drill and tap the tail of the light to fit the clip?
It was my birthday and I got some money, to be spent on something exclusively personal and unnecessary.
I treated myself on a Cypreus 18650 host 
, really looking forward to that!
And Iām sure you will be a very happy camper! :bigsmile:
Missed the party didnt we? :party: belated hbd mate! That is so nice of you
We are, Not worthy! 
Hey scotty, Iāll try to take better pictures later but here are the three clips I can install for your Cypreus EDC
Every time I see these lights I go weak at the knees. Now patiently awaiting my birthday :bigsmile:
Excellent! Excellent! The pocket clip with screws is perfect. Going for a run now, will PM this afternoon.
I have avoided looking at this thread until today. I love budget lights, but these hosts are seriously tempting! Works of art.
Go aheadā¦
Sinner, what is the overall length of the 18350 copper?
95mm (3.74ā)
Working on the Cypreus-EDC-18650 , they will be available once again by the end of this week
Now available, Spacer for Tripple/TIR:
$7.50 (Aluminium) $12.00 (Brass) $18 (Copper)
Iāll add the info on the OP.
Thanks, sinner! These are great EDC lights!
Now, what is that I hear about brass flashlight hosts?
Thanks man. Brass, Stainless Steel, and Aluminium versions - In 2 Weeks.
FREE Shipping for the next few orders , Thanks.
:bigsmile:
Aluminum! This might be closer to my budgetā¦ How much and is the pill copper?
Aluminium one has the copper pill aswell. They will be $55.00
What is your turn around time for the aluminum host with pocket clip?
They will be available by Aug-5th
