Nice! Love the S41 so this will be great. Signed the form. 2x Nichia please ! 
So we should be receiving an email or private message some time today? Looking forward to spending more money than I should (although this light is priced just right!).
UPDATE 16.May2017
Code is working!
i mailed / PMed all names on my list!
if you do not receive something please check your spam folder (maybe whitelist @m4dm4x.com)
or feel free to contact me
I didnāt get a email or pm.
I donāt quite get the UI. Is it a single click on and off?
219C version ordered, thanks! 
Theyāre out of the 18650 tubes, so it looks like Iāll be buying some 18350ās. Can anyone recommend what type/where to buy (for delivery to the UK)? I assume itāll need unprotected?
Ordered 1 x Nichia 219C, thanks!
18650 tubes (and codes) will be back soon i was told
Pre-ordered 1 - Nichia 219C. Thanks, Martin!
Wow! That light took a jump in price! Thanks so very much for this group buy! I appreciate it.
Now the waiting for my Nichia-equipped Astroluxā¦
I canāt order this light is because the extra 18650 tube is unavailable now!
Ordered a Nichia! I wanted one of those battery tubes but I can wait I guess.
I figure that if I can easily recharge this light (at home, work, car, laptopā¦), the shorter runtimes of the 18350 cells I have will be ok. Iām planning on using the Efest 18350 V1 IMR 800mAh cells I have.
Oh, and I canāt wait to try out the survival hammer! :smiling_imp:
Thanks, Iāve just ordered one.
Is there a code for the extension tube?

Order placed for 219C.
Thanks Martin!
I did not get a PM or email about it.
Ordered 219c - Many thanks!
Scott.
I didnāt get a Pm either.
I may not need the code but banggood only allows me to add in the wishlist instead of add to cart!
