Not from the GB, but yes SOLD ~

You have it right, if I remember I’ll take a tail cap current reading tonight.

I’m just going to take a guess… approximately 3.76V at 0.50mA. Based on your estimated voltage so far and the voltage-to-mA curve I measured months ago.

I just measured 0.46mA

Still waiting on my order of the aluminium set. Placed the order on 22 February with BG. No updates or movement whatsoever.

Was this with 3B tint? If so, you may want to check with them via live chat. I ordered another set of AL 3B on February 20 and after days of inactivity I found out they were not expecting them until March 6.

Christ! You’re right….I didn’t even realise there were other types. I’ll contact them. Thanks.

They seem to have both tints back in stock right now so just ask them if they have enough of the 3B to fulfill your order and when they will be doing so.

You are correct.

The tail light can drain the cell far enough to damage it. It can go down to at least 2.2V or 2.3V, possibly farther, and cell damage starts around 2.5V-ish.

On my X6, LVP turns the torch “completely” off at 2.86V

By this point the tail LED is drawing only 146 microamps. But still glowing dimly.

(Actually the sort of dim glow that I would have preferred.)

It would take an awfully long time to take the battery much lower at this sort of current. I am not concerned about it.

However, if the torch was left switched on, relying on LVP, it would give a false sense of comfort.

Because I have measured the current draw in the “shut down by LVP” state, at 2.86 V, as 6.14 mA. Which is almost entirely due to the permanently in-circuit 470 Ohm bleeder resistor. So will continue, in a linear fashion, all the way down to zero volts. At a fair rate. Definitely resulting in killing the battery.

To summarise: tail LED draws only 146 microamps at 2.86V. But leaving the torch “shut down by LVP” drains the cell 42 times faster.

Sharpie, thank you Very Much for the valuable info.

G'Day BLF'ers,

Has anyone received any email or PM reply from Neal/Banggood regarding problems/faults with their X5/X6 flashlights?

- If yes, did it satisfactorily resolve your problem(s)?

- If not, how long have you been waiting for a response from Neal/Banggood?

Please let us know.

Thank you Very Much,

George

Why can’t BG just take one off an Astrolux, and send it to you.

Then re-fit the spare, once they actually really have it.

Since obtaining the spare is not going to be a problem, I can’t see why they should have an issue with this. It’s not like there is any risk that they would be stuck with an incomplete product.

But if they were, I suppose they could break it down for other spares, that might be appreciated by other customers.

Until I can see a package, hopefully containing what is supposed to be inside, moving through e.g. 7track, I don’t usually hold my breath.

Nor have total confidence that it will have the correct contents, until it has arrived, and opened it.

The short answer is because its a business.

I totally agree that they should consider replacing defective parts.

But can you imagine the headaches about trying to tell warehouse workers (probably a different location then Neal or Mgt) to pull an item out of stock, make the inventory adjustments, then take the right part off, then package it up to you properly, then communicate that this was done, then “order a replacement part, then keep keep on the supplier for the replacement part, then if and when it arrives inspect it, then find the (”undamaged partial item”) and re install it, then re inspect it, then make the inventory adjustment then put it back into stock. Never going to happen!!!

But maybe BG can create an RMA/QC department and have them take on these tasks for (all of there items for sale???) or maybe Neal can get some support for his R&D/”pre production builds”. Because lets face it that’s what were are to BG, free R&D and a group who will pay for a pre production run. So that the bugs can be worked out before they go into a full production run.

@scrumpypaul

I’m not able to wade through nearly 7000 posts…… Can anyone point me to a link of a detailed review of the aluminium set please?

It’s bloody awesome! That detailed enough for you?

To be honest, I haven’t received any 14500 batteries yet, but the bigger brother is fantastic, and I have no doubts about the little one being just as good. I hope the batteries I’ve ordered is good enough though, the X6 is pulling 5 amps…

Maybe I was lucky, but mine are pristine and look gorgeous. Love the lighted tail cap and the interface. Amazing flashlights for the money imho.

Martook - bluntly - yes, it is detailed enough for me!!! :nerd_face:

I’ve just ordered a 3B set - hopefully they’ll be shipped quickly.

Thank you

Scrumpypaul,

No one has done a review of the aluminum set. Feature by feature, they are basically the same as the SS/Cu set. The only differences are:

the various differences you listed - thank you

So, keeping in mind these small differences, you can find all that you need to about the AL set by looking at a review of the SS/CU set: A first look at the BLF/Kronos Limited Edition X6/X5 SS & Cu Boxd Set

cheers 1dash1 - I have read that review and ordered the Aluminium set - thank you for your help.

a small box of spares (maybe under Neal’s desk), then he could just bung them in a jiffy bag to we beta-testers

That fits my suggestion for subsequent group buys: everyone participating agrees to be part of the “charlie test” (alpha, beta, ‘sorry Charlie’ … software process steps)
and so Neal only has those names as acceptable for questions/replacements — to keep the parasites from jumping on trying to get more for their money by claiming problems without helping solve them.

… tail LED draws only 146 microamps at 2.86V.

Yeah, unfortunately there’s nothing I could do about that.
I wonder how feasible it would be to give the MCU the ability to block the bleeder during normal operation. Standby current (after LVP) could potentially be as low as ~0.01mA then.

The only way to stop these lights from draining a cell is to physically break the circuit, like unscrewing the tailcap a bit on the aluminum models, or taking the battery out on the steel/copper ones.

Hank, I do NOT think the use of that word is wise, as it will have an intimidatory effect on many members with genuine problem(s) that may be afraid of being labelled as such.

We want members to feel free to post here regarding their problem(s) with the lights &/or the supplier(s), WITHOUT being afraid.

To put it simply and really embarrassing, NO! X(((((((

[edit] Waiting for 2 and a half week now - not anywhere acceptable…

{edit2] I think it is time, any person involved in the GB should intervene!

[edit3] I will wait another week and simply open a palpal dispute, the only way to get them awake… >:cry:

If they can not send a replacement of damaged tailcap then they should send a complete Astrolux…

The Manker mark has very good QC, the Astrolux mark has good QC but when it is made with the BLF mark the QC is poor or… inexistent.
