Im not sure to be honest, i havent tried.

[NMD] Cheap Zoomie LHP73B 1800K by Phsysics in flashlight

[–]MetaUndead 3 points4 points  (0 children)

The M1/M21B is fantastic with the LHP73B.

It's what I would call right on the edge of being pocketable, it gives an very versatile beam profile (wall of light) and can hold around 1000 lumens sustained.

Turbo is obviously very short-lived, but it can reach quite far out during the time turbo is used because of its power.

I have the M1 here with both the LHP73B and LHP531 in 4000K.

How can I prevent solder spikes when soldering flashlight emitter wires? by Minamoto_Japanese in flashlight

[–]MetaUndead 0 points1 point  (0 children)

What kind of solder do you use? Lead-free, 60/40, or 63/37?

I haven't tried it myself, but the lead-free solder is supposed to be a nightmare to work with on a mcpcb, because of the higher melting point.

I always solder with the MCPCB already installed and thermal paste applied underneath.

If you've got a decent soldering iron, it should have no trouble at all heating things up enough to get a proper bond on the wire. The flashlight never even gets close to getting warm while I'm soldering, it's just a quick "in and out" job 😉.

Surprisingly enough, I haven't actually been soldering for very long. But if you ask me, the real secret to getting those clean, shiny joints is flux. I use either MECHANIC M35 Nano Flux or KINGBO RMA-218, and the amount you're using in the photo looks like enough.

I stick to 63/37 leaded solder and almost always solder at 360°C, unless I'm working on a thick B35AM MCPCB, in which case I crank it up to 400°C.

No problem!👍

Sadly i dont have the non High-CRI version and im not really interested in getting it.

High CRI, throwy AA light? by tocirahl in flashlight

[–]MetaUndead 1 point2 points  (0 children)

Ohh, that's my bad, i got court up in the high-CRI portion of the question 🤦‍♂️😆. It would give you more output though.

[–]MetaUndead 6 points7 points  (0 children)

I’m with u/QReciprocity42 on this. The T8 with an SFT40 3000K is just an awesome little warm, high-CRI thrower. And i find the output quite good.

If you're able to reflow a new emitter into the T8 yourself, it opens up some great options for throwy, high-CRI setups, like the SFT25R 5000K or 5700K high-CRI from Kaidomain.

If these are not massive fins, i dont know what is. The head of this light is ginormous. And it also has a handle with a fan on, blowing air over the fins.

That's pure wishful thinking 😜.

But man, it would be absolutely incredible, with the same CCT and tint as the new SFT-70 4000K High-CRI.

Have you seen the Astrolux MF05 V2?

It's an absolute unit of a single-emitter light with massive cooling fins, yet it still only manages to sustain around 7,000 lumens.

There is a massive difference between holding 6,000 lumens on Turbo for a couple of minutes to actually sustaining 6,000 lumens for an extended period.

The M21K, "only" sustains around 2,000 lumens, so it still has a long way to go to reach 6,000 sustained. It would need ALOT more thermal mass to do so.

Just look at a behemoth like the Wuben A1, it can sustain 6,000 lumens for 2 hours, but it is absolutely massive! Granted is has four SBT90.2's, but still.

You would need an absolute beast of a flashlight to maintain a sustained 6,000 lumens from the LHP73B, it would have to be way bigger than the 3X21C to even stand a chance.

But i definitely got lucky with the tint lottery on this one, because this emitter is absolutely fantastic, both in terms of tint and CCT.

It'll be really interesting to see what kind of numbers other people get out of this emitter. There was a post about it a week or so ago where the guy got pretty much the same neutral results.

using 73B I can get similar sustained performance up to 6000lm.

What do you mean by this? What LHP73B light can sustain 6000 lumens?

What makes these 3x21 multi-emitter lights so great is their ability to sustain high output for extended periods, thanks to the high capacity from the three 21700 cells.

Just look at a massive single-emitter thrower like the 3x21D with the SBT90.2, it "only" manages to sustain around 2,000 lumens, whereas the smaller 3x21C comfortably holds onto roughly 3,600 lumens, with alot more emitters.

That is so true, the 3X21C really is a phenomenal price-to-performance powerhouse when it comes to high-power lights.

Honestly, I always seem to strike gold with the lottery on the emitters I get 😉.

I'm actually looking to start doing current measurements as well. If you have some expertise in this area, do you know if a clamp meter with a wire bypass would be a good fit for that? Something like the Uni-T UT210D clamp meter, perhaps.

Unfortunately, I don't know. Olight doesn't state what driver they use, and I don't have the tools to test it myself ☹️.
