Is it possible that there are gaps in LS3 serial numbers? Perhaps some did not meet ARC's quality standards for 'firsts' and the 'seconds' were never released, accounting for Nekomane's high serial?
Here's some good LS3 reading from the past:

Just wondering where you heard about the 3 dozen figure from George? Got me curious now too.

It's there on the first post in your last link
I have another LS-3 #44 and have always wondered what happened to the S/Ns in between.Gransee said:
I was an Arc fanatic a few years ago (well, still am but am just waiting for some new products) and
this has been one of the unsolved mysteries even after scouring the Arc forums.
Hey, nice to see some long gone members in those threads too...

Yes, there were about 40 or less made. I don't have the exact number. There are holes in serial numbers because not all met the QC standard and so were scrapped.
The most unusual LS3 was one I made for Merri that has a 5w dental blue luxeon. She brought it to the most recent phx GT. She also brought it on a recent camping trip. I bugged our fellow campers with it. It tends to mess with your vision. The rocks in the area we went camping flouresce (or reflect oddly) so the effect at night it unique.

ARC LS1 and LS2 with both cr123 lgihts with a low dome one watt luxeon.
LS3 was world's first production 5watt Luxeon light and used a 2x CR123 body. most had a puke green tint. simular to how most low domes had a yellowish tint or greenies.
it's incredeble how far were have come in a few short years. now days if we don't get a perfect white tint....

Yes, the LS3 typically was a bit too green for my tastes. It was partly because of the bins we could get back then (remember it was the first production 5w) and the fact the LED was underdriven.
I didn't like the beam it produced and there were other things I didn't like (hard to remember them off hand) and so I stopped manufacturing it.

UV peaks at about 350nm-360nm...Doug said:
Royal Blue peaks just below 450nm and "regular" blue at about 460nm...
Check DS45.pdf on the Lumileds site also...
Back to the LS3 topic...
So Peter, the LS3s that got "scratched", where did they "scratch to" ?

Hey, it never hurts to get in line (behind me, guys).
Still on the LS3 topic...
Peter, do you know what (voltage) bins were used in the LS3's and what the drive current was set to ?
Also, there were a few Arc4s made with 2x123 tubes,
what were used in those heads ? (currents/emitters)
Thanks !!

Now I am sure there is no line for these, but if by some chance there was I would love to be included.

Bombel, IIRC, the boards in these things were modified BB500's (but I may be mistaken).
:thinking:
Here is a pic of what it looks like:
This is a pic showing an Arc LS3 head (#51) opened up.
The emitter is a 4-die LuxV. There is also an optic inside the head.
(not sure which optic it is)
I have a WW0S emitter, but would it make sense to replace the stock emitter with this WW0S ? And what about current ?
Cheers !
