My order from Banggood, placed April 21st
for an Xpl-hi 4700 variant just shipped…

That was fast… Silly

So the XPL HI 4700K in now in stock.

I ordered the 4700K at the same time and BG cancelled my order even after I asked to wait. Question

Seeking the light.

Haha… well, that didn’t take long. I got an Amutorch E3 in the mail yesterday. I did a runtime test today and after 25 minutes it got hot enough to desolder the ground wire on the MCPCB. The body had hit 75°C. I immediately aborted the test, but the “damage” was done.

On the plus side, I registered 3300 lumens at turn-on with a Molicel P42A and SST20 4000K’s. Much brighter than I expected. But then again, the light paid the price for it. Cool Looks like a custom Anduril2 driver is in order along with some RGB aux (twas my plan all along anyway).

I know it comes with a boatload of heat, but seeing 3000+lm capability and Ra95+ and R9-90ish reaffirms my affinity for this emitter. More meaningful IMO is the relative CD/LM you get from them. I’m looking forward to whatever you cook up! This light is dangling on the edge of my wishlist – along with a few amutorches btw- just needing an efficient driver to pull it up. Series config mcpcb and boost driver is my hope

Well, on the plus side… the driver appears to be a Buck + FET so it could be pretty efficient if you’re not using Turbo (much). I was planning on measuring non-Turbo output but it got desoldered first. And while I had the iron out, I just went ahead and took the driver out so I could measure it. Once I get the new driver designed and am waiting on PCBs, I may throw the original back in temporarily to play with. I do know that when it dropped out of turbo, it went down to ~850 lumens. I’m not sure if that was the top of regulation or not.

Edit: disregard, this is a Linear + FET driver

Oh wow. Thought these where FET only, possibly linear, but never thought it was a switching circuit

Ehh, I’m a bone head. Please disregard that. It is indeed a linear circuit – there’s no inductor. The linear circuitry appears to use an extrenal op-amp, separate FET, and a large R050 current sense resistor. I really shouldn’t try to work and analyze drivers at the same time. Facepalm

Sorry friend!

Although I didn't produce or send you this flashlight, I’m sorry anyway ...

 

embarassed

No worries… it’s not going to cause me any trouble. This light is a nice, very small hot rod. I would still recommend it, but with the disclaimer that when it starts getting hot, make sure to decrease output! Temperature regulation appears to only affect Turbo mode, not all modes.

I’m not sure for the E3, but for the E3S the KR4/KR1 deep-carry clip is an option. The tip protrudes about 1mm past the bezel on the E3S. And the rear extends a bit past the end of the tailcap. But it fits on there!

Dammit Scallywag. No clip kept this off my list. I love the kr4 clip, now I think I have to buy one. Fin, any deals available for the E3 these days?

Get someone to measure the E3 just in case. Also it will spin some since the keyring-thingy it came with lacked the o-ring that Hank uses to keep his clips from moving. Although you can probably just add one, I guess it will show more on the E3(S) since the tailcap doesn’t accommodate it like on the KR4

Wonder if anybody is going to make a 21350?

My E3S came with non-carclo optics but they’re fine. I got 6500K SST20 since it was the last purple in stock. They’re greenish a tad on low modes but quite good at higher currents. I’m not sure I’d buy the E3 myself, even in purple, since I need a new UI and I don’t envy dropping stuff down the 700 tube like gchart did. It will be tough enough with the 350 tube hahaha.

For now I’m trying my new suspension clip with it still, which is fun since I’ve never carried anything with a suspension clip before. Although presently it’s crippled by the UI it’s a nice photon nugget on turbo.

A suspension clip on my FW1A has been my daily mode of carry for over a year. Took a minute to get used to but once the muscle memory was there, I enjoyed many benefits. The comfort of a lanyard without the snagging.

Is it just me or does that looks like the Emisar D4.

Well it’s a triple and 21700, so at least it’s more different than that new Jetbeam.

It’s also unibody – heat flows from head to tube a lot nicer.
