As good as it gets: Hard User tweaked the beam cast before deciding to sell it to me.

Here, an awesome Oveready rig with their DIP dropin. Note the TIR irregularities in the beam.

 

[KITROBASKIN]

Speaking of beam casts with stuff, here is a favorite EagTac D25LC2 mk2 (now relegated to backup in work pack because of the Emisar D1) probably designed for a different LED but has the notable sst20 for decent throw. Check out the ring outside of the hotspot.

Bam, and it takes the higher capacity batteries.
It's asking to be ran over by a train, but then you'd derail the train.

 

[KITROBASKIN]

Really enjoying the ability to use some of my larger diameter, longer protected batteries in this tool.

Getting to know this dimming capability, I used a head strap to enable constant use for over an hour putting together a small cabinet. Sometimes the light intensity wavered, even blinked a couple times. Not the end of the world, but something to be aware of. Occasional brief use seems very normal with a steady light output. This flashlight can go really dim but the consistency seems to be more of an issue at lower adjustments (Thinking all of this has been covered before)

Is it not a good idea to tighten too firmly to get maximum brightness?

 

[thermal guy]

I don’t think they recommend over tightening it. Mine will act up from time to time. And I will have to pop the QTC holder out literally just put it back in and it’s fine. Not sure why.

After adjusting the tailcap inner spring base, this Fraz flashlight is wonderfully functioning. Tried a Sony VTC variant and it works so well. Since its arrival, I have used it every evening; just love it. The coating/anodizing is smooth/pleasing to the touch. Edges are radiused to perfection (inner edges both sides of narrower body have a little sharper angle; genius!) It is a wonderful size and solid weight but not too much weight.

Added some brass to my collection

I'm getting hour an a half runtime each evening for a project. Think I've work out the regulating material... light flickers for no reason and doesn't get beyond ~300 lumens.

Pop out the holder for the capsule and reseat the capsule on the magnet and then pop the holder back in, it should be back to normal. This happens to me if I twist too far. The capsule will continue working fine after reseating in my experience. Don’t even need to flip it over just give it a wiggle or a slight turn.

 

[KITROBASKIN]

Rarely now does mine flicker after adjusting overall internal length. When setting it down on a table in tailstand mode it will blip once.

Wondering if Tentative Meteorite might do a simple video showing how to reseat. Seems like Fraz had a disassembly video but I just wanted to be sure for the future.

 

[thermal guy]

It’s very simple. Just tap the body upside down on the table. The QTC/holder will fall right out then if you want you can remove the QTC pill and put it back on. I never do. Then using pliers put the QTC holder back on. That’s it.

 

[fulee9999]

Hmm interesting. Mine never flickers. And I often use it as abmient/aux light, so it stays on sometimes all night.

 

[Berserker26]

Mine flickers a little at lower ramp, but only when ramping then it settles in when you stop twisting and there's no flicker.

 

[fulee9999]

oh you mean while adjusting it it flickers! yeah, mine does that, I thought while left on. I believe it's normal QTC behaviour, my Logan does that as well.

Exactly, or even wide tweezers. It can be done with fingers but it’s a pain! The small brass cube pops out, the capsule is a small black disc of rubber that’s held in place by a magnet. I just wiggle that black rubber a bit and slot the brass block back into place after. Make sure to note which side of the brass block has the deeper Groove and put it back the same way, or just be ok with breaking in the other side too.

I rotated 90 degrees.

Worth noting that the light doesn't get hot anymore when running wide open.

Take the QTC pill out and see if it gets hot. That’s supposed to be full power.

Same/slightly less bright than malkoff md2, so maybe 300-400 lumens IIRC.

No heat yet after 10 mins, room temp.

Brightness appears same regardless if 'magic dot' is in there or not. Color is on the green side a decent bit.

Is my emitter cooked? Link for a replacement?
