1. The whole point of the video you linked is described at minute 16:20. The cooler tightening down pushing out any excessive paste, meaning that the layer of paste will always be as thin as it can get. From what it sounds like this would not happen in the E07 unless the MCPCB gets bevelled because it does not touch the surface beneath it.
5. I don’t know but there are images of it here: Fireflies E07 | Taschenlampen Forum It’s also a light with broken aux LEDs which is the reason he opened it up in the first place.
6. Nope. SST-20: Fireflies E07 preview - #801 by DB_Custom And Fireflies said that high-drain batteries should not be used with SST-20 and the Nichias. In comment #901:Fireflies E07 preview - #886 by FireFlies “* For E07 SST20 / Nichia version , we only recommend max 20A battery , 20A battery can reach max power for E07 SST20/Nichia version. With a 30T battery on SST20 or Nichia the turbo will go blue no matter how much paste used.”
There are just too many things going wrong imho. Many of which might be small issues or even non-issues for some, but there are just too many things wrong to wave it off. I did not compile the list of issues already found to nitpick on each and every detail but to express my concerns with Fireflies QC and their responses. Most of the issues aren’t even adressed. So why do a “premium edition”?
I hope so too and I hope we are both right. And I agree with that the 40Ts being fake is not confirmed yet. I will adjust that statement in my post above. But at this point with all the open issues and unanswered questions, doing a “premium model” seems kinda counter-intuitive.
But Fireflies already admitted that (and not due to excessive heat, apparently). See quote at point 6. again: “For E07 SST20 / Nichia version , we only recommend max 20A battery , 20A battery can reach max power for E07 SST20/Nichia version. With a 30T battery on SST20 or Nichia the turbo will go blue no matter how much paste used.” I have not found this recommendation anywhere. Does it come with the instructions maybe?
Edit/P.S.: I don’t want to give the impression that FireFlies is the devil himself. Far from it. They produced a fabulous looking light. They listened to us when we demanded a clear anodized version. (Which is the version I ordered) I just can’t wrap my head around all those tiny details they are lacking. That are sometimes so obviously wrong. Like the PL47 headband. I am really looking forward to their future.
It may be that the Nichia or SST20 just can’t take the current and that’s why they are going blue. If that’s the case, then no amount of improving the heatsink path at the star-pill interface will help. The problem is the peak output of the light is too high for the emitter when used with a full cell.
I still don’t see an explicit warning (all I see is “For SST20 version, around 20A discharge rate needed, LS 20A 21700 recommended”) but it’s good that they now have better recommendations online… I guess I will try mine with the 30Q to get to know how sst-20 look like before attempting the emitter swap to Samsung.
For something completely different: I have seen people with a mixed blue/purple aux-LED setup. I would have ordered that but I couldn’t find it anywhere so I went with just purple. Are those custom modded or would FireFlies have done that if I had asked?
Edit: Here is a sample image on Neals page (but apparently those are the generic FireFlies product images):
