New LuckySun BLF-D80? Production has started

Update 19.05.
- The production run has started. They will produce 250 with XP-L-Hi and 250 with SST-40 5700K.
- Here some vids from the Factory: Tailcaps fresh out of the machine , Tailcap gets Milled, Tube fresh out of the machine, New Tube threads (more will follow)
- Driver will be send to Lexel for checking (They tested the driver directly wired to a Chinese 13A continious discharge cell at 4V and got 7,2A)
- Reflector LED hole is adjusted to 9mm to make space for the SST-40 (LS will send 2 centering rings with the light. One for the SST-40 and one for XP-L-Hi size leds so later modding is easier)
- Color is not decided now. I try to get a list of possible colors (if possible pictures) so we can open a poll and see what most people like.

Here the pic from testing the driver

Update 15.04.
Here a to do list

- 1. Tailcap change so the light can Tailstand ( Thumbs Up )
- 2. Threads change to square threads ( Thumbs Up )
- 3. Changes to make space for 20mm driver (slightly bigger tube) ( Thumbs Up )
- 4. Changes at the head retaining ring to make sure it will not come loose ( Thumbs Up )
- 5. Internal changes of the head to help with heatpath and dissipation (thicker shelf, walls, deeper finns) ( Thumbs Up )
- 6. New driver designt by Lexel with Bistro UI (in work)
- 7. Upgraded reflector to get best throw /check for possible TIR (they want to test it when samples come in)
- 8. Reflector LED Hole rezise from 9,5mm to 7mm ( Thumbs Up )
- 9. Small adjustments on the front to get better sealing (will mark it on the picture) ( Thumbs Up )
- 10. New springs
- 11. Making sure unprotected and long protected batterys fit (tube length) ( Thumbs Up )

I got some new drawings. There is still some small things that must be changed. But i thought i upload at least one new pic (the others that show the internals will follow!)

Maybe not the best form for Tailstand (a bit unstable) but looks very nice and will feel good when you hold the light

And here a Pic of the internal structure

They shorten the front a tiny bit so the o-ring gets compressed a little bit more. Original the front o-ring was sitting to loose. Now it will seal much better.

Original first Post 10.03

Today i got the mail, that all the old BLF-D80 are sold.
Now they would like to make new ones but they would like to know what we want to see.
I can not say if they will do everything we want but maybe we can get a few things done.
So let me know what you would like to see.
I think :
1. New drver. Fet + 1 or something similar with Bistro UI
2. New LED (XPL-Hi for the big market, some High CRI option for BLF)
3. Maybe a change in battery size (21700) / head size (propotional increase). That should also increase the throw and heat handling capabitities. I am not good with designing a new look so i am not trying (but if you think you can do it let us see what you have in mind).
4. Double springs like the Blue Springs
5. Option to buy it as a Host (my prefered option Big Smile )

New LuckySun D80 looking good so far http://budgetlightforum.com/node/66255

Keep the 18650.
Use the new XHP50.2
3 volt LED, with appropriate driver and springs.
Watch them sell like hotcakes.

The size / shape of the host are what defines the BLF-D80 for me. I'd keep that.

Upgraded internals? New driver/emitter/software?

Heck, yeah!

I guess you mean XHP 50 .2 3V ?

About a new D80:
*keep the design, at least the shape
*keep the 18650, the D80 has a great compact feel
*a XP-L Hi is boring but probably right. The 3V XHP50.2 plus FET driver makes it a hotrod not suitable for the general public
*FET+1 with bistro is nice, but with an improved board lay-out to prevent voltage spikes, so that modding the light with low voltage leds does not give trouble.
*improve the reflector, the old D80 has an imperfect one.

It will have a tough competition with all the X6 and C8 versions around, so the last tip: while keeping the fat head and its shape and fins, and keeping the possibility to use protected batteries, if possible make it even more compact (shorter) than the original D80.

The BLF D80 was before my time but your post about them last year got me interested in the LuckySun brand. They really need to update the their driver and emitter offerings, but selling bare hosts would be even better.

My wishlist for a new D80 as a ready-to-use light is:

  1. A triple channel FET+n+1 driver with OTSM running Bistro, or at least a FET+1 running Bistro
  2. BlueSwordM springs (nickel-plated is fine)
  3. anti-reflective coated lens
  4. choice of emitters – XP-L HI (4000K 5A) and something cheaper with higher CRI

I like the idea of a D80 with a 21700 tube, but I’d be quite happy with just an upgraded version of the existing host.

djozz has just convinced me that I don’t want a 21700 D80. Smile

I love this light!

I think it looks awesome probably the best gray colour anodizing going around and the SS bezel looks awesome. The AR lens is good quality.

You could beef the light up a bit make the fins a tad different like a bit thicker and add a bit more separation. Give it a thicker shelf but that would require heaps of work but seeing as the driver cavity is fairly big it might not be to hard. I think it would look awesome just by up sizing the head make the reflector a tad bigger so it looks a bit more bulky but not to large.

If it stayed as is no problem either.

My only issues is the stock driver is okay but nothing special even if they want to use a linear driver make it a few more amps. I had the battery tube problem with the short tubes on one of mine. Plus the stock spring are horrible this is a Luckysun issue i have other lights that have massive crappy springs. Also maybe get rid of the square knurling nothing wrong with it but its kind of dated and the grip is average.

I know that the 3V XHP50.2 would be nice, but it’s way too powerful for such a host.

Something like an XP-L HI/Luxeon V would be great.

And yes, dual nickel-plated BeCu springs would be awesome. Would make the light perform light a superb hotrod.

No, no! The shape is what sets the D80 apart, makes it attractive to some of us. It’s main problem for me is that it gets HOT very fast when hot rodded. I have one with an XHP50, first series, that runs two 18650 in series.

Yes, djozz, I meant XHP50 3 volt. I editted my post, thanks. I think it would be a great hotrod single emitter, in a world where most of them are becoming quads or triples.

I don’t have any quads at all. I do have an X6 triple with a FET driver running a 30Q cell. The modded D80 does get hotter and gets hotter faster than that X6. The couple of other triples I have are not true hot rods so it is not fair to compare them. (I like my triples mostly for their beam patterns, not the total possible lumen output.)

The shape is best appreciated when you have one in your hand, it just feels very good, much better than a X6.

Regarding a design change.
I was thinking about some performance changes (like a thicker ledshelf). And maybe (when addressing the tube length) also go for a more uniform design. Now you have many different design elements on the tube. And it is not repeating itself. So no design element from the tube is found on the head or the tailcap. . . . Look at the C8+ or the S2+ for example. You will find that they use simmilar elements on head, tube and tailcap.
But i will send LuckySun what the majority wants!

About the 3V XHP50. I think its a perfect LED for hotrodding a light. But not usable with a FET driver in a comercial light (liability. . . ).
But if they use a propper driver with all the other improvements it is a easy and fast mod to a 3V XHP-50 if someone wants to build a hotrod.
To be able to sell the lights to the mass they will most likely go with a XPL-Hi. But i hope they will also offer some high CRI options like the SST-20. . . . on copper DTP boards.

Do you have a link so i can give them something they can look into?
A upgraded reflector would be nice. But is it possible to increase the throw without changing the size? Or do you mean that they should try to get better (more clean, less flaws. . . ) ones?
Propper springs are a must. And i will link the Blue Springs. So they can see how a propper spring looks like. Cool

Thanks Don. I was wondering whether the heat would be similar to an Emisar or upcoming FW3A, and I assume it would, but it would be a single emitter hotrod this time.

TheOnlyDocc,I get what you’re saying about emitter choice. It will probably end up very similar to what we have already seen, on this and many other lights. I guess that will appeal to more people, although it would be just duplication for many as well.

My experience is that it is impossible to explain to a chinese manufacturer the improved board layout as a description of the problem and then an explanation of the fix. You will have to hand them litterally a correct board lay-out. And I can not draw circuit boards. The description of the problem with the Attiny25 based FET+7135 driver ( drop out of turbo when using low voltage leds) and the required fix is here: http://budgetlightforum.com/comment/1061998#comment-1061998

Feels like the throttle on a motorcycle.
Maybe that’s an idea, slip a motorcycle grip over the tube, no more hot hands Smile (Yes I know it will eliminate using hands as a radiator causing light to become hotter but for regular use what the heck, work with me here people)

That is a problem, the new D80 will need something that the others do not have, and that is its unique looks and nice finning. If the rest is done well it will become popular (at least with me Smile )

What about if there was a new D80 version using an e-switch on the side as well as having a tail cap switch? The head would need a little lengthening I guess.

Plus the driver is already 20mm on the D80 gives them a few more options they could easily fit in a 22mm driver. I’ve seen some one making 5+ amp 7135 drivers on Aliexpress. That could be an option with a 3v XHP50.2. How about a high powered linear BLF driver?

I am thinking host only may be the way to go. If they try to make this a perfect light for everyone they will fail.

or make it cheap and simple, but mod friendly:
-18650
-efficient emitter
-simple driver with only 1 or two levels with no step-down ever. no blinky modes.

Personally I like tail clicky lights, but I understand the attraction of e-switches. In this case though, fitting an e-switch on the side will alter that nice shape of the D80, it adds a section just below the finned area that is somewhat wider than the battery tube to house the switch.

Upgrading the tube to 21700 is good, it would make you current; even strengthening it with an XHP50 or 70 is fine.
It may also have a USB support, on a separable module, such as the JKK26 (which it resembles); would also be a powerbank and the USB port would be safe from the elements, much better than a rubber cap.

I’m still looking for the holly grail of what I want in a flashlight.

High efficiency LED….I don’t know which of the above is efficient in the 400-500 lumen range.

Single 18650 if you must, 21700

Orange peel reflector…repeat….ORANGE PEEL REFLECTOR

Shallow reflector.

~

The video I saw of the D80 with a very small hot spot and large spill is deader then dead to me.

I know we want our flashlights so powerful so we can look for alien life on another planet, I just want a large and smoothed out beam that I can use for everything (but not alien life search). Best of all if it has full smoothness from center out to with no additional spill.

If this thing comes in for $20 range, put me down for three.

Keeping in mind the letter B (for Budget) , in BLF, I think it should be kept simple as the old D80 was.

*No USB charging.
*Possibly no side e-switch, although I sure prefer them.
*A choice of smooth or orange peel reflector could be nice at times.
*A reflector diameter that is compatible with some of the available multi-led optics would be nice for some of us who like to mod.
*Better heat sinking for the head than the old D80
*I would prefer to keep the tube sized for the 18650 cell as I like the slimness.
*The option to buy as a host would be great so we don’t have to waste a driver or mcpcb when we mod it

An e-switch would be nice if it could be kept off the driver board, probably too hard to do on a light this size. If the switch is on the driver board it makes modding hard.

It sounds like the light has a pretty nice reflector, may as well keep using it.

Could the gap be widened between the cooling fins so air can move through them better?

With the low VF of newer emitters buck and boost drivers will become more popular, it would be nice to get more space for the driver. 22mm with a deep cavity would be nice, maybe bumping up to a 21700 battery tube would make it possible.

Don’t glue anything together and include some 18650 adapters.

Sell it with a basic fet+ driver and an xpl hi led. The good springs and driver parts are too open for counterfeiting, that’ll just end up causing the manufacturer grief.
