Yes and no. It’s not a “bare” LED with silicone coating or dome. It’s a 5 mm LED with hard plastic housing, sitting in an aluminum “reflector”.
correct, that is normal, no glass lens needed nor available.
the 5mm LED is manufactured with a waterproof optical dome, and installed with an O ring around the base. No water or dirt can get into the electronics.
if you had ever seen a Fenix E01 (which cost more and was not High CRI), it had the same no glass lens. It is a very durable design.
Enjoy! 
Thanks Jon and Sammy! I was surprised that there is no glass lense but I don’t think sofirn will forgot the lense there must be something I’m missing. Lol
This is the first kind of light I have with this design. Very interesting.
Confirmed unpotted colors (for modding) are Desert Tan(Brown), Blue and Orange, correct?
yes
NOT potted C01 colors:
brown
blue
orange
YES potted C01 colors:
black
green
red
Great. I’m going for some more. 
Just adding to the dataset. Received order from Sofirn website, blue and orange not potted, all other colours potted (didn’t order brown so can’t comment).
There’s some variation in the tint though and unfortunately for me the potted ones look the worst.
Also, the new colours are very nice, the green is lovely, as are the blue and red (now deeper / richer).
What is the best solder league to put on the positive driver contact to protect it from scratch?
In the past I used Sn-Pb 60/40 but after a little use it blackened and had to be cleaned, I thought it was caused by the presence of lead
Buy enough C01 lights, Sari. I’ve used one from the initial batch multiple times a day. Still intact pads.
From djozz:
How to add brass foil on the contacts
Q:
You can also get gold contacts.
https://www.aliexpress.com/item/33040243320.html
pure 24K is probably too soft.
plated Contacts should work better
or this: Gold plated copper
a quick google says, that is not correct,
lead tarnishes to a dull gray color
Tin tarnishes black
When I clean threads on a lamp it is always dark grey smudged.
There is no solder, lead or tin, involved in your case. It’s just aluminum.
Nice find but I already have some thin nickel plated brass sticks.
my question was about the marks on positive driver pad caused by battery pole
I wanted fix it with a small solder blow from an alloy that does not form oxide and more hard than SN/PB.
Sounds like you want precious metals
Trying to order from Sofirn but they ask for a lot. Can’t just use PayPal. Just gave up.
you could sweat solder a small piece of sheet silver on there instead, it`s a better material than gold (or anything else) even it`s oxide conducts as well! it`s also a soft metal. I replace all sorts of flashlight parts with pure silver, it`s worth getting some in (for everyone into repair and modding).
Thx for suggestion 
Will try Ag sheet if I find it
Yea by the time they charge shipping at Sofirn same price. I was thinking folks were getting the c01 for $4
