It’s copper main body with TI batt tube and bezel. The other issue besides baller bling is that the TI conducts heat extremely well and makes the entire light, your hand and the cell get extremely hot extremely fast. My raw alu E07 just on stock top of ramp still reaches 50C in like 2-3 mins. Holding a light that’s batt tube is 40+ degrees after a minute wouldn’t be worth the baller bling imo
You should be cautious not using turbo too often and for too long if you didn’t correct the LEDs MCPCB because it is not sitting properly on the head’s shelf and the heat isn’t evacuated properly to the flashlight’s body. Particularly if yours is the Nichia which heats up very quickly.
Nice idea but one has to be careful with the SST40. koef3 discovered that the bonding wires already burn with about 9A and more than 7.4A are not reasonable. However, maybe the N5 flux bin is less sensitive to overcurrent than N4 tested by koef3.
@SKV89, what do you have in mind ?
Personnally with a “big” TIR, i’m immediately thinking to Clemence’s VR21SP4 MCPCB with the hope to find a frosted compatible TIR.
I’m surprised that my E07 dropped in output significantly over time. For example, my XP-L HI version that measured 7,327 lumens with a 30T now measures 5,950 lumens with a 30T, 5,820 lumens with a 40T. I don’t even use this E07 besides blasting it on turbo every now and then for output measurements and tint comparisons so I’m sure it never overheated. My other E07 also lost some output but not as much as this specific one. I leave the cells in these flashlights for the aux light for half a year though. Does the driver degrade over time? Maybe Lexel might be able to answer this since he designed the driver.
Anyone else noticed their E07 output decreases over time?
It must be the LEDs getting super hot, but the light throttling down too soon.
The 1st gen didn’t have a good flat MCPCB with very poor thermal paste contact. That means the LEDs could easily be at extremely high temps without you knowing.
Do you leave batteries inside your E07? I’ve kept the aux lights on for half a year. Not sure if that is causing the lower output because the one that dropped output the most, I almost never use it.
Do you have any fresh cells to compare with ?
That they drop in lumens and if its not cell related does sound worrying… especially after such little use…
I am little bit disappointed with the lack of scientific reviews and tests. Sure… there was a kind of big flood of reviews earlier this year…but honestly…it feel like
all those old reviews are not as relevant today because manufacturing process have changed since then, we should see now much improved thermal performance for instance.
The most hardcore flashholics nad reviews did buy it very earily when it still had some manufacturing problems which should be fixed now… it would be interesting to see how the thermal performance compare with those that are sold today.
it feels like the E07 is not as hot anymore in terms of discussions etc, maybe people are just waiting for the astrolux MF01 Mini, which now seem to be delayed… if I am going to pull the trigger and buy the e07 it would be more confident how to see how the older version and the newer versions compare… it seem many of those flaws people have complained about have been fixed…
Fireflies had E07 IV on their banner for a short time…now its gone… I wonder if they will release a E07 with this branding so one can be confident that you don’t get something from the old batch (which I think is probably unlikely if you buy from their official store), but if they only have E07 from latest batch with perfected manufacturing I would not see why they would not rebrand it so people know its an updated version.
