Review: Convoy S2 2800mA U2 1B from Fasttech

[264]

Good review Bort. Nice writing and photos.

Can somebody point me to the right usb programmer for flashing the driver please? Thanks!

@Bort

According to the Cree Product Characterization Tool an XM-L2 U2 at 2.8A (85ºC) produces 937.1 lumens, assume about 75-80% OTF and you get about 700-750 lumens

ok thanks! i didnt have anything to compare it to except a 150 lumen light and a friends 272 lumen mini mag and it is brighter than both of those.

@WarHawk-AVG

honestly I don’t know…I was going to get one, but never got one so I don’t know

i might be the guinea pig and give them a try.

If you get standard star fw, its a throttle after 120 seconds, it will throttle back to around half power after that. I found 120 seconds to long, my s2 got uncomfortable to hold. I use the same throttle back value, but after 90 secconds on full power. Now it stays in the comfortzone ( in winter i would really like it).
60 as WarHawk-AVG uses is rather quick and won’t heat it at all i suppose.

i got a custom star firmware, its going to be 90 seconds. but if i add 7135 chips to make it 3.3a or 3.6a, 90 seconds might be to long. i need to get the flashing tools to experiment. i have a usbasp flashing tool for a turnigy 9xr transmitter, but im unsure if that will work. i need to get a eeprom clip to find out.

long term use update above

thanks bort!

No problem, i just just put another 3 hours of use on it today, did some spray foaming of gaps in the basement and elsewhere and starting installing a new washroom subfloor

i’m happy to visit, i can even purchase a chinese stun gun, i bet DX will have some for sale, i hear they can be quite motivating j/k J)

I have the opposite problem, i have so much to do that its going to take months to years to finish it, though i also have motivation issues, i just end up forcing myself to start

Negative, I never got any in

I did however change the firmware…I put STAR with the ability to auto throttle and after 60 seconds drop from “Turbo” to a lower mode as to not overheat, still runs at 2800mA but instead of running wide open and getting INCREDIBLY HOT it gets warm then throttles back, the light slightly dims when it drops back but no longer overheats

do you know if they will work or have the same threads?

i dont have the flashing tools yet, but i have a qlite 3.04a driver with star firmware on the way along with a noctigon sink. i dont run my s8 on high very long. its plenty bright for close up stuff on medium, but outside for longer distance, i always want just one more high mode for a few seconds. i wonder how many lumens the xm-l2 2800ma is?

I have different turbo timeout times on my STAR builds…

I built a small 16340 Ultrafire 602B, w/ a 4*7135, there is almost NO pill, very very thin, and even running a XP-G2 at 1400mA, the light gets hot fast, the Convoy has a little bit more meat and doesn’t heat up as fast…I think I have it set for turbo timeout fallback at 60 seconds (I think I am going to reverse the H>L though…have it start in L>H, this way the kids don’t get it and immediately fire it up wide open…uggh

The only lights I like to fire up in High first click are my “bump in the night” sock the badguy in the puss with as many lumens I can muster on first click, but have turbo timeout to fall back to a more reasonable level so as to not overheat

if i get woke up by a bump in the night from a badguy, i will sock him in the puss with high lumens followed by xxx buckshot…… :bigsmile:

Exactly…but positive identification of a target BEFORE you send rounds downrange is paramount…otherwise that $18K bill attached to every bullet you shoot comes into play

I send flying ashtrays

Thats why i would use a flashlight, far less lethal but quite disabling, the Convoy M1 would work quite well

Let’s quit side tracking this awesome review…maybe we should start our own thread

it sure is, bort did a fantastic job.

i would like to start my own thread but not a defense thread, but an s2 or s series mod thread where everyone can show there mods. i just got through modding my s8 with noctigon sink and qlite driver with star fw off-time mem running at 3.74a. it is noticeably brighter…… i wish i had a way to check lumen output…

going off topic is par for the course on BLF, so i don’t mind, i thought it was funny i was mentioning another Convoy light on a review for a different Convoy light
