I do not see the CS on the nichia website anymore have they been discontinued.
They have no reason to continue it, since the DS line is physically the same, and is superior in every way.

Maybe, but consider that the GS is only rated currently at 10% higher typical intensity than the DS, but 1/10 the life to 70% brightness. That I had to get from my local Nichia rep., she said 2-3,000 hours for the GS, 30,000 hours for the DS (similar to the famously tough CS's). That would be at 20 mA, so don't expect 3,000 hours in our typical lights with significant overdrive, although I still doubt many of us will run a GS to where we can tell it has dimmed from use.
Can anyone confirm this, not that I doubt Hondo. It has just been my experience that reps from different manufacturers have been known to give mistakingly wrong information
Compare the datasheets.
To bring this thread back on track, could more people who have received their GS fauxtons post your impressions? (I'm talking about those who ordered for the actual keychain light, not those who want to scavenge the LED for another body.) So far it seems evenly split: those who really like it vs. those who think the old fauxtons were better or at least as good.
I ordered when these first came out thinking they'd be much brighter than the 10-pack lights. When my order was delayed due to another item on the same order being backordered, I cancelled my fauxton order. I might order again if enough people respond here positively, but it sounds like the improvement in brightness can't justify the cost increase.
Thanks.
I've received them and they're my first fauxtons of any kind.
My impression is very good.
they're extremely bright at least 50% more than my e01.
Quality seems to be ok for what they are, but i'm not sure how long it would last in keychain use.
does anyone has any reports on how this would run on cr2032?
Cheers
Update: I'm having contact trouble with the CR2032 cells but, strangely enough, not with the 2xCR2016.
Basically if the legs aren't pushed against the cell with considerable force, the LED flickers.
I tried another non-GS LED and it does the same thing, even if I just hold it on the cell with my fingers.
But if I just touch the multimeter probes to the cell they'll give consistent readings without the need to press on them.
I tried with multiple cells, including a non-DX CR2032 I have sitting around, and nothing changed.
If I just slide the LED inbetween two CR2016s, no flickering at all even with no pressure on the legs.
I cannot for the life of me figure out why this is happening.
Thanks for the link.Nichia not only still makes the CS LED's, here: http://store.nichia.com/index.asp?PageAction=VIEWPROD&ProdID=138, but the old BS LED's.
Thanks for the link.
I haven't found the DS nor GS on their store, don't they sell them?
You're probably right. I'll see what I can do to solve this problem & report on the results.Bingo! Glad I'm not alone. My guess is that at higher voltage, a little resistive loss at the leg contact is no biggie, so the 2x2016's switch on like magic. We are running so close to Vf with the 2032's, only perfect contact gives consistant light output. I have no problem with this in my GS Photon Freedom on 2032, but the GS is soldered to the board and the battery is held firmliy in gold plated contacts.

Hmmm, interesting. I've noticed the same problem with these but, oddly enough, not with my "real" Photon II DS. I think that the Photon LED leads are gold plated so maybe this helps? Bummer though, these things are beautiful on 2032
It's not all that bad, I find that it just takes a very deliberate squeeze, in the center of the light. I don't seem to have a problem getting it to stay on steady and bright using the constant on switch, either, but I have tweaked with the LED leads to optimize it while trying to improve the momentary contact.
Fallingwater, good luck on the improvements, I would be interested in any more simple tweaks to make this setup more robust. In addition to playing with the bend of the LED legs, I have treated both the insides of the legs and the surface of the battery with Deoxit and Progold, but seem to have hit a stone wall in getting easy, reliable momentary activations on 2032's. But as I said above, it is still very usable, just not as rock steady as the Photon Freedom. Hmmm, about 10+ times the price, and it works much better right out of the package, I guess that makes some sense .
