Convoy L6... XHP70 Beast!

Thanks for the code JDub-74, great price :beer:

Wow - quite a deal indeed! Thanks! :beer:

Is there any problem with Simon business?

Closed for the Chinese New Year holiday season, back open 15th February I think, no problem with his business :+1:

Correct. It’s shut down time in China. The whole country stops for nearly a full month. It should be declared an annual month of mourning for flashaholics. :cry:

You were the one to say that e-juice would blow up li-ion cells and now you question my credibilty, common man :confused:

That is nice, and I admire your work. But how does building lights give you insight into the technology and chemistry that is inside the cells? Have you read books on that stuff, or is it just forum-knowledge?

I will not further comment on this in here, primarily bc. this is taking such a nice thread soo off topic. So do not answer. If you want a serious discussion start a thread about it in more fitting subforum and I will give you some of my time and stay civil about it if you do.

Easy enough to guide a conversation away from the mainstream but then that leaves a lot of people wondering… I am not the inspector that checked out downed burned planes and concluded that vape liquids and crushed Li-ion cells were the origin. I only read those reports. I read tons of stuff… granted, I forget tons of stuff and of the bits I recall there’s always a possibility I get the facts crossed. But I do KNOW that early airline incidents were blamed on vaping supplies that got crushed in flimsy packing materials in a cargo bay. I also know that because of these incidents, we went through quite a spell where Li-ion’s were difficult to obtain.

I’ve read extensively about our cells, and how they’re made, and what makes one higher quality than another. I’ve delved into long reports where these cells were cut open, were forced to vent or explode, seen a lot. Seen reports of lights burning down apartment complexes when left on a charger, similar to the airboards and smart phones. Seen video of Li-ion cells spewing like a rocket out of a vape device after it’d been sub-ohmed to volatility while the consumer was making a purchase in a store. Seen pictures of a young man with his face burned beyond recognition when his sub-ohm vape unit had the cell explode while he was drawing on it.

Without anything backing your stance Benjy, it’s just so very difficult to give you credibility with 3 posts, controversial at that. Civil? But of course. I don’t personally know more than 2 or 3 of the 1500 people here, so of course civility is the rule. If you’re the CEO of Panasonic and you’re coming in here to enlighten us, please share your creds so we can buy in. Otherwise, you’re gonna have to give us some credit for having a lot of experience here in this forum.

We are a widely dispersed group here, we live around the globe and occupy virtually every job position known. We are brought together by a common interest in lighting our way, helping others, and having some fun along the way. All of our conversations in these million posts are read by old timers and noobs alike, so one persons response to another is usually viewed with a lot of interest, on both sides of the coin. I know a little about a lot of things. I’m not an expert on much of anything. I DO know how to get a lot out of a flashlight, that came with a lot of trial and error and a stubborn determination to build build build. Much of this fueled by an avid interest in research. Always open to learn something new, and fully aware that mainstream information isn’t always the full truth, so if you or anyone knows something that we’ve all been missing, by all means share away… I’ll keep my Sharpie ready to take notes. :wink:

Benjy, DB Custom, and whoever else; whether it is done in this thread or a separate thread all it’s own… I really wish the discussion of Li Ion batteries would continue. Why you may ask……… because I would like to know once and for all what the truth of the matter actually is. :slight_smile:

Whether the person sharing info be a seasoned forum veteran, a newbie, or anywhere in between…… if they know their stuff; I’d like to hear it.
But I’d also like to be able to read references to back up what is said. That in itself would cut down drastically on opinion & BS that is shared. It would also galvanize credibility.

So for those that can back up what they say, I would really like to know the actual science, technology, & chemistry of the rechargeable lithium ion battery. Not just what I have heard or think I know……. :wink:

Update: After bypassing both springs with 20AWG silicone wire and improving the driver ground contact, R100 resistor modded L6 current draw: 6.94A with fresh liitokalas, ceiling bounce equivalent: 4,150lm.

Not sure how accurate my ceiling bounce method is but it was sort of calibrated with other ANSI flashlights, although much lower in output. Very pleased with the results, and the driver is cheap enough to replace if it ever burns. :smiley:

I will also be keeping my Sharpie ready to take notes :wink: :wink:

Let’s get it ON! :smiley: :+1:

I’m using an FET Zener modified driver in my black L6 and it’s doing right at 12A for a little over 7000 lumens. This is with the top tier XHP-70. It’ll get hot too, but most of the time the night air is enough to keep it real. These lights are just exceptional, another one of those that makes people want to liberate the light from your possession. :wink:

Hmmmm……… seems I missed that one. :person_facepalming:
KB, you have 36 of them. :open_mouth:
Could I please borrow that Yellow Sharpie, if the time ever comes to take notes that is? :wink:

Is it just the photographer in me or shouldn’t Kawi have much better lighting than that? :stuck_out_tongue:

Hey man that’s my 3300k-3500k?
LED lighting in my kitchen, I’m trying to get with the program here, don’t the colors just POP! :person_facepalming: :+1:

Lithium Ion battery discussion should certainly continue but we’ve spun out long enough for this thread haven’t we?
It would probably help more people if it were moved over to a thread dedicate to the topic like the Lithium-ion battery safety 101 thread.

I totally agree…. we have surely spun out enough. :+1:

Only reason I wrote what I did above was because one contestant suggested the debate take place here in this thread.

Personally, I just wish for the discussion to continue. And as far as I am concerned also, a dedicated thread would be the way to go to actually get to the real truth of the matter. :slight_smile:

That's great results! I further updated my black L6 mod to an SMO and a P2 1C, and now getting 6,700 @start, 6,250 @30 secs, and 149 kcd taken at 5m. I measured 11.45A tail (Clamp meter).

I knew I couldn't match your results because I think you did some machining for the MCPCB and could use 18 AWG wires, I think I recall. I'm still using a SinkPAD MCPCB.

Still, with Narsil ramping, TA's triple w/SIR800DP, and 62 uA parasitic drain, it's a nice setup. The SMO & P2 1C mod bumped it up by about 500 lumens, and from 132 to 149 kcd.

Couldn’t remember exactly what it did so I charged up the pair of Basen’s (4.21V) and ran it through the box… 20,700 on the meter for 7141.5 lumens (start). This is TK’s ramping firmware with an SIR800DP FET.

The cells were down to 3.85V when I pulled em to charge and it was still making 5745 lumens.

5745 out 3.85v what the , I been away for two long , what kinda light is this you speak of ?
