The C8, C8+ and M21A uses the exact same reflectors. I had a Astrolux C8, and still have a Convoy C8+ and 2x Convoy M21A.
EXACTLY the same reflectors. Just keep in mind the M21A has a froward clicky switch.
I’m looking for a 3000k xpl hi to put into a FT03 ,would this be worth it? Anybody knows if exists such a led? Thanks
Yes XPL-HI in 3000K do exist and are available from Simon at his Convoy Aliexpress store;
V2-1A = 6500-7000K
U6-3A = 5000-5200K
U6-4C = 4200-4500K
U3-7A = 3000-3300K
Thanks for replying, would it be a better thrower the FT03 with xpl hi vs sst20 , less heat? Is it worth it to gain more throw?
well 3000k is a weird tint to have in a thrower imo…best is to use a neutral tint instead. but it will be less heat if thats what u after tho.
There’s lots of frog in here,that’s why I’m looking further for a 3000k tint
I’ve found an XM-L2 running at 4 amps gives a really nice amount of light in a C8 and there are stacks of tint options… But if you are thinking about a bit more power you might want to take a look at the M21A & L21A
Both have the Xhp35.2 an SST40 options 
The M21A is really not much bigger than a C8+ but gives you a 5000mah capacity
K ,I like FT03 body, and now I’ve got the sst40 and xhp50 version. I’m thinking that could improve throw ,or at least maintain it with a xpl hi ,where I can choose the tint , in my case 3000k ,which I really need and like. What do I need to switch the led? New driver, 16mm or 20mm, new center ring? Thanks
Or you could slice the dome on the sst40 and increase your throw.
What is an NTC?

I sliced my SST-40 in my FT03 and only gained 80 meters. Won’t be doing that again.
just wondering, how comparable is the battery life between the sst40 vs the xpl hi? I ordered the C8+ SST40 5000K and have some samsung 35E 3500mAh batteries for it. Is the battery life reasonable?
Which driver are you using?
The 4-mode driver. Hopefully that answers your question. I dont know much about flashlights haha. I ordered that option from banggood.
35E will give you good runtime. Easily 1 hr. on high mode
If the driver is 5A then it won’t give 1 hr on Turbo. Well, it might, but not at that Turbo brightness.
Using the 3A biscotti driver with XML2 using a Panasonic 3400mAh battery I got 1 hr 15m until the battery was at something like 3v
High mode on the 4-mode driver is 30% so 2A.
It’s only just above 1A for 600 lumens. It’s certainly not ideally spaced levels
High - 600 lumens
Turbo - 1560
That’s a big gap
is it perceived as a big gap though? I thought lumens weren’t really a linear type of relationship in terms of magnitude of lumens and perception of brightness.
With the SST40 it appears twice as bright
600 is fine for general use up to 150m
1560 gets 300-350m effective
