Thanks, it looks like I had inserted the URL of the flickr page, not that of the picture itself. I have edited my message, which is now OK.
Thanks for this thread, it was realy helpfull.
Just modded my Zipka with Nichias GS, the resistor is an original 3.3 ohm yet. Yes, it come very bright. But with fresh alkaline AAAs the current is 195 mA now, i.e. 65 mA per LED. With original LEDs it was 150 mA, 50 mA per LED, which is much over rate too, and the current will essentially go down while the batteries drain. But now the beam comes blueish (in a center), it seems to be a bad sign for a LED...
So, will it be lethal for Nichias if I leave this 3.3 ohm resistor? Thanks for advise.

vmspb: how is your light going?
I have a Zipka with 4 LED's I'm hoping to upgrade as soon as I can find the emitters. The photo below is what I have for internals. I don't know where this resistor is, but whichever one of those do-dads it is, its pretty small and I don't think I am going to be able to replace it. Will this MOD work anyway?

It's still alive, thanks
I use it rarely though, powered by 3 x LSD NiMH.
Regarding the bluish tint, it seems to be a feature of Nichia GS LED.

Thanks Cemoi, that thread has some good info.
This is a bit OT, but I have a bike light with amber LED's I'd like to change to white Nichias. I'm very much an amature at this, so forgive my ignorance but what is Vf and why does it prevent the guy on that thread from replacing white LEDs with red LEDs, and will this also be a problem if I want to swap amber out for white?

I had the same projects a few months ago. Solving it made me learn a lot of things (mainly thanks to CPF), and I have now a much brighter front light.
See the details in this thread.
Which bike light do you have?
Looks like you'd be better off reading the welcome mat. Anyway yes swapping amber LEDs for white will probably not work, you need to boost up the voltage supplied to the LEDs. The how-to is in the above thread, in post #15.
Good luck, there is much to learn here.
