I don’t understand why there is little aluminium mass directly underneath that plate of LEDs (think ROT66) and all that heat sinking around an area that will hold little more then a switch.
Not an expert on thermal management but I challenge some of the smart people here to talk me thru how this design is going to manage the heat.
Or maybe that’s not the point in this case and if so apologies for raising this.
How can you tell there is little aluminum mass? The E07 had a very thick aluminum shelf under the mcpcb. It had some of the best heat sinking property for its size. I hope the shelf thickness, which is most important for heat transfer, remains thick like in the E07
The design seems to have further reduced the mass of aluminium that could conduct heat away by adding a ‘heat sink’ groove right where there should be a large body of mass to conduct heat away. It appears to be bottlenecked at the place that most needs material.
Bonkers! Haha
Edit: Just saying I can’t recall a design that undercuts the diameter of the aluminium that houses the mcpcb quite like this.
I wouldnt risk mine, UNLESS you told and show me how the 12 leds will be batter able to hold X amount of heat where it goes through Y’s dissipation. Hehe, my hope that will solve. I’m not sayin they can’t anyway…but what are the possibillity?
I’m very interested. It fits my preferences almost completely. I like floddy flashlights, so I’m happy with XPL HD but with so many emitters the HI led is also fine.
I don’t like builtin chargers. I understand that you try to increase sales but for a device aimed at enthusiasts this is bad.
Please use good o-rings. The E07 has bad ones, they get lose and pop out when you lubricate; in the Cu-Ti version of the E07 they’re so bad that I ended up removing it, so it’s no longer water-tight The red o-rings are much better, please use them.
I suggest you ask Maukka to do a through review. They’re very useful to our community.
It is a powerful floody light when used at max power, but we do not have to use max power. It can also be an efficient dim floody light with long battery life.
There has been quite a bit of interest on BLF in deep red flashlights recently. Sofirn C01R sold out fairly quickly.
Many special uses:
night light that does not contain any blue light, which causes suppression of melatonin and prevents you from sleeping
once your eyes adjust to the dark, deep red light allows you to see clearly without destroying your night vision
Acturally compared with ROT66 , E12R has got more heat-sinking surface due to more and much deeper fins. Heat-sink is not a weak point for E12R. Turbo mode is only supposed to be a short-time use, in this case , adding more weight wont help too much for more runtime on turbo, anyway E12R is not designed to be a bulky light. We still keep it in compact range as possible.
