The price is quite okay for me: the driver is exellent, has tons of features, shipping time is like i got it from here
15$….2 packs of cigarettes… Eu freacking tax anti-tobaco policy FTW! P:)

Anyway, Neven, what are your recommendations for hosts ? I found C12 to be a very good houst for it, C8 even better( easiness of use) , but it cant handle the heat properly

Yezl i Y3 i coudlnt master :/ Yet, i ordered a new one….. and a new soldering station ! Also, HD 2010….

ON the Road X6M would have same issues like Y3, the driver diamether is 30.5, at least the el switch is separate

Maybe Convoy L4?

P.S I would need aditionaly 3 pcs, so when awailable i will order asap

Is there any way to reduce cost of these with a large enough group order and what would the number be? Love the driver idea, but it almost doubles the cost of the lights I want to put them in...

If l4p would have them made in large quantities, I'm sure they could be made a lot faster and cheaper. But he made a brand new driver with very good features and it took him many months to develope and test it, so he is entitled to see some of that back in his sales. A large-scale production run would spoil that.

It would not necessarily spoil it. He chose to do them by hand because of the unknown popularity and the quantity required to do a pick and place run. I am sure that if he had enough prepaid orders that it could be profitable. I say prepaid because something like this requires capital. I do not know what the minimum quantity would be for p&p but I do know that I have spent at least $50 on dinner that was pure crap so to commit $50 to a large run would not be a big deal to me if others would want to jump on the same train.

I have the same problem with copper-alloy springs that I had made 200 of by a spring factory. They are good springs of a type and quality not for sale elsewhere, but are too expensive how it is now. If I order 2500 of them they cost 3 times less and are a really good deal on a quality component. But I'm not going to invest 700 dollars not knowing if I get them sold.

1000 people just prepaid to get the BLF X6. Why couldn't 1000 (just a number) people prepay for a driver. The PayPal excuse is out of the window too because it no longer is 45 days. If 100 people went in on 3 each................

Thus, the mention of a groupbuy, and the suggestion of pre-pay. I’m still contemplating buying some of these at the current price, when I get the spare cash (and they’re available to buy Wink ), but a cheaper price does sound tempting, and I’d be willing to buy more of them than I originally intended, so that there is enough money flowing to get the price significantly lower, if that is possible. We just saw with the Eagle Eye X6 what can be achieved when enough people get on board with a group-buy. :bigsmile:

Yeah, we didn’t pre-pay, but we are still getting people wanting more lights: the Sign-up List thread is still active! Pre-pay isn’t a bad idea, though, since we have here a guy we know we can trust. Wink

Maybe not with $10,000. Silly (1000 people at say $10) Just sayin.

Plus I already bought 4 at full price, so no discounts for yous.

Obviously we need to set up a micro-lending bank, all contribute toward its assets, and use it to encourage creative people who want to build things new in the world — then boost their ideas into mass production so everyone benefits. “To the future … and beyond!”

But I’m not gonna wait, the regular price and quantity 3 isn’t too much for this high end work. (pm sent)

Mitko, the Convoy L4 is problematic for a driver swap. It’s driver is larger than 17mm, it has the e-switch mounted on the driver board, so it requires piggybacking a new driver which is not idea for the LD-1 as it would then be “air mounted”.

The Eagle Eye X6 benefits greatly from this driver and it’s an easy replacement. Wink 1500 lumens otf with a Pan BD cell. Best of run time and very good output.

There are several reasons why I didn't talk about mass quantity/group buys yet:

1.You can't know possible interest without running relatively small test batch;buying 1000s of parts is too risky if you don't know how big the interest is,

2.Driver design is still "fresh",not ver1.0, but I see place for some improvements;when I think that design would be "good enough",then I can think of larger production

3.Even at 100-200 quantity I'm having problems with parts availability,that means I'll probably have to buy full reels from various sources,and that's a lot of money

(mouser,digikey etc. often have  "only" few hundreds of the same component ,they go fast,and lead time for new stock from their sources are often in months).

Same thing happened with first batch,PIC12F1840 was out of stock almost worldwide,but thanks to OldLumens who ordered them from Newark,first batch was successful,but with 3weeks delay.

P&P service fee is quite high >1000$ just machine start.I considered simple DIY P&P machine,I see there are some on net,but I don't have time for experimenting and building such machine,and there is always a risk of complete fail:)

True, EE X6 will have one for sure, but my main goal now is to make 1500lm thrower. and here the leading part is exacly that driver, cause i need a single cell thrower

Yeah, i could buy Olight M2X-UT Javelot , but i dont like its switching mode, m24 sniper is a bit large, and not 1500 lm
Plus, i think its the best for one to buld his flashlight, then he values it most Wink

> I see place for some improvements

Well, I’d be glad to commit, make a deposit payment toward, or pay for three, whether of the existing or next version.
Think about what would encourage you.

I know one can be wise not to take money in advance; it can lead into problems — I’ve seen that many times over decades.

But I like being able to find people who do this sort of thing that I wish for but won’t be doing myself.

This is part of the future I was hoping to live in, and I’m glad I lived long enough to see it starting to happen.

Mitko, at the risk of sounding like an Eagle Eye X6 fanboy… a de-domed XP-G2 R5 1A at near 5A will do ~100Kcd.

About to test a SupFire F9 with a de-domed XP-G2 S2 2B that I just built, cell is charging.

Well, everyone has their own reasons for their own price points for components buying and selling. Mine is I was thinking I would be able to order multiple Eagle Eyes for gifts with significantly higher output than they have, and since I don’t want to double the cost of 5-10 lights or so, and I’m deficient in the experience/skill some of you have, so its a pretty significant cost for me!

It just looks like a nice driver and I was hoping there was an option to lower the cost by buying more, it seems we have a lot of interest already, and then that interest was amplified by the X6 not performing turbo to a level most are satisfied with, seemingly enough to get hundreds of these ordered I’d bet.

Yeah, talk to me about EE X6 love, i ordered 4 from the GB Smile Its truly a nice torch, i prefer it over Skyray or Xint, or C8, or any of the flashlights that i have – ofc for all arround use, even from M22- more pocketable, same beam pattern, even same emitter tint and colour( maybe they are same)

Will do ofc, how do X6 performs with XPG2? I have never tested that emitter( r5), only at work, but lower bins, usualy arround 3-5k q3-4, and since XTE is widely spready arround here we usualy work with XTEs

After dedoming, hows the colour? cause i absoolutely dont like wha i see on most XML2s, they became either too yellowish, or green, or even brown…..currently i have only one bin that i acceptable after dedoming, t6 7000k from FT

I get the impression that 90% odd of those who complained of lack of amps in the X6 would not even wire the springs,let alone change a driver.They probably do not own a soldering iron,and many lights were for gifting :santa: without even opening the box.I’m sure the X6 group buy will generate orders for the Led4power driver,they are made for each other.But it will be in the dozens,not hundreds,because modders only,even if a simple mod.

Ahh, I don’t know, especially if it were say $10 range. +.3A seems to be what the spring wiring does from tested reports, this driver allows for a lot more significant results for the work than that, plus more functions/modes and no PWM! Smile

I don’t know about problem units, but driver swapping has definitely been done by Dale in a BLF X6 he modded for SB. Dale has said that the LD-1 is an easy switch-out for the stock driver and makes an impressive difference.

Unfortunately the ‘problem’ units are the ones that really matter when it comes to the topic of potentially popular driver swaps on the BLF X6. We all know that DBCstm is capable of squeezing high current out of a stone.

Has to chuckle. I like what L4P has done here and hope it inspires him and others to continue this kind of effort. It doesn’t always pay off monetarily so something very like a GB can be helpful in spreading risk.

Djozz, for things that everyone uses like springs it might work to go ahead and set up a prepaid investment thread to purchase custom PB springs in a larger quantity since it would take the buying power of many of us combined to pull it off and commitment to buy from even more. A custom mcpcb would need this approach but one person would still have to be point man to set it up and disburse packets when ready.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

Hopefully these will make the BLF X6 even better than it is now (Especially when the 25R batteries arrive)

Do these come with a spring mounted?
