Guys, do you think I would gain more lumens by replacing the double springs with my BeCu springs, or would the forward voltage of the LED be too high for any meaningful gain?
I would like to know.
Couldn’t hurt.
It’s the single driver spring that would most benefit.
It looks like the xpl can survive up to 8 or 9 amps before burning out. I’m getting 5.5A stock. I don’t plan to mess with it, but if you bypassed or replaced the driver spring you might see 6A or more. Peak power for the xpl seems to be at 7A, but the heat is massive.
DB Custom stuck a killer Samsung 30T cell on his and got and extra 250 lumen so I would say there’s a bit more output left.
Yes it has big difference:
My C8 intensity and throw numbers to compare:
XM-L2 2.8A: 32.5 kcd 360m
XP-L HI 2.8A: 54.5 kcd 464m
XP-L HI 5.9A TA17 fet: 93.1 kcd 610m
Dedomed SST40 8.6A TA17 fet: 136.3 kcd 738m
Great info JasonWW the light is sure worthy gt mini 
it blows any c8 out of the water!
So I did not get the track number
A month has passed since payment
Very bad, gentlemen merchants
They only started shipping them about 1 week ago. Have you PM’ed Madmax or Neal about a tracking number?
pls send me your paypal mail
I will check the shipment
Those last two are pretty close. I wonder why the Mini beats your last one? It seems like a beast.
Maybe it’s the reflector? It’s slightly wider, 39mm to 33mm and about 9mm deeper. The mini has an AR lens, my C8 doesn’t. This might give it a definite advantage.
It is definitely the reflector diameter that counts. But the last two has AR coated lens. Forgot to mention.
My Emisar D1S with XP-L HI has 124.1 kcd and 704m stock
but with the same dedomed SST40 what was in the C8 I got 160.6 kcd and 801m
There’s no need to talk like that.
So they did send you a tracking number, but it was the wrong one.
Are you saying you already recieved your order? Was it correct?
Ah, was your D1S CW or NW? If NW, that might explain why it read 124 kcd and the CW read 148kcd.
I know the sst40 is CW and it’s a powerful led with low forward voltage. I would expect it to get above 148kcd.
No, of course, I did not!
Do you think if I received an order, would I ask so many questions?
Martin sent me another’s track number, promised to send the present and is silent as a fish on the ice for three days already)))
It is NW
I got confused when you said you “already received goods”.
I would not worry about 3 days. That is a very short for a Group Buy.
Did you send Neal the email address that is linked to your PayPal account? This is how he can find your order. I don’t know if a phone number will work. Maybe Martin uses the phone number, I don’t know.
Anyway, I think Neal can help you out.
Mine arrived today thanks. Such a tiny flashlight. :+1:
pls PM me your paypal mail
so that I can check your order

UPDATE TO MANUAL
After trying mode 4 and mode 10 it appears that the groups are reversed.
Modes 1-6 use full turbo as 100% (5A)
Modes 7-12 use the top of the ramp as 100% (2.5A)
We definitely need an updated manual to reflect this.
Edit: And here it is.
