Links now go to the english side.
I just received my D80 with the extension tube and opened the extremely plasticky smelling packaging. I like the looks of the light, especially the fins on the head. I was hoping it would weigh more for better heatsinking but I guess the cooling from the well done fins will help. The quality overall looks great.
Have you seen the beam profile yet? The D80 has a large hot spot that is very well defined, a unique combination not found often. Semi stage lighting in appearance. I wasn’t fond of the styling to begin with but the beam profile won me over very quickly. 
The hotspot is a very well defined circle with some corona and very dim spill. Kind of looks like a Emisar D1. I picked the 3000k version which is way too yellow. I don’t like it. I will probably replace it with a 3000k SST-20-W 90CRI or a 4xE21A but worried about donut hole.
I also don’t like the UI that much. It goes from Hi to Low instead of Low to Hi. It does have mode memory but I rather it go from Low to Hi without memory.
Well, yeah, they bonked the UI, but the beam is sure nice! lol
I have my BLF D80 sitting pretty with an MT-G2, that’s the only one I have left from back then. The one I ordered recently is in the wind somewhere.
Somewhere I have a bag full of drivers removed from D80’s… 12-15 of em if I recall correctly.
Edit: I see 10, 5 clearly the brass button Lucky Sun D80 drivers but I’ve robbed the others of the little 3 legged MOSFETs and other parts, button included, and tossed em I guess. Too much stuff here to remember where all the bits are…
You bought 12-15 D80s?!
Damn that is a literal lot of the same light.
Built more than 50 Eagle Eye X6’s. Give em away, here and there, sell one or two, down to the one D80 although I have a dozen or more X6’s here.
Oh, to help clarify, I’ve been on the group buy teams and tested prototype lights more than a few times.
Got the D80’s big brother, the F3X , a triple… built it up with a copper pill and re-worked the extension tube to be the main tube, like it a lot in it’s present configuration. 
I like the challenge of building a light in as many different ways as seems reasonable. 
Like, I have 14 X6’s, all made differently from an Oslon Black Flat to triple XHP-50.2’s, XHP-70.2 to SBT-70. It’s fun to see what can be done.
Like the X6, the D80 is a nice platform for building lights…
Now, this D80 that’s en-route… seems like a likely candidate for an LED4POWER constant current driver set up for around 9A to an SST-40 that’s sliced and diced. 2400 or so lumens, tight defined hot spot, what’s not to like?
Considering this is a BLF light, I’m surprised forum members approved of such a poorly designed UI. I guess this still makes for a good host if you swap the driver.
I actually don’t remember, seems like we didn’t approve, but that doesn’t mean Lucky Sun wasn’t stuck with a bunch of drivers…
Not so very long ago we had no say in what the UI was like. Members here changed all that, for which the noobs can be thankful. Bad UI’s and blinkies is what caused me to learn to build drivers. Once you know how to do that, you welcome a bad UI.
The group buy started in January of 2015, by September we had samples and were giving the greenlight… 711 members here were on the list with the H-L set-up well known. Price was around $20. I was on the team, my protected cells fit, several other testers also had protected cells that fit in the shorter tube. I don’t use protected cells myself so the shorter tube wasn’t an issue to me then, nor is it now.
Mind you, this was a different place 3 years ago…
I see. At least there’s no blinky modes I guess. I might just replace the driver. I actually really like the host design. Thanks for the info.
kronological
Foy,
etc.
Different place for sure
Good memories none the less.
Thanks

Old Lumens, ChicagoX, Wight, Bucket, MattAUS, Comfychair, the movers and shakers that are now missing, AWOL, or have left us altogether. 
(my memory surely fails to recall more)
A certain squirrel was omnipresent, as I recall…
Heck, some of y’all probably even miss Sharpie! 
We don’t miss Sharpie. We have Tom Tom now. :person_facepalming:
IIRC, kronological was in the ‘throwers should start on high’ camp and requested the UI that way. Not my preference but a reasonable UI, especially compared to the original UI; Six modes: Mid2-Mid1-Low-Strobe-High-SOS :confounded:
Still for sale there.
I put a shaved dome SST-40 in mine and bypassed the tail switch. The black centering ring started melting so it got replaced with a smaller white one which isn’t a great fit and not perfectly centered, but close.
Regardless, light does ~6A on turbo with a Sanyo NCR18650GA cell. I think that is about 1,465lm. I actually got around ~200 more lumens when I changed centering rings.
The driver’s retaining ring doesn’t want to budge. I was going to take a look at it but I gave up for now. If I replace the driver I guess I will worry about it then.
Contactcr, check to be sure it isn’t left hand threads on the driver retaining ring… you could be tightening it trying to loosen it.
