Ordered a couple 64mm. That makes 16 lenses I purchased this week from Ric.
Which lens will fit the M6 Supfire everyone is waiting for?
Ordered a couple 64mm lenses. Thanks ric. 
Received my first order of AR coated lenses. They look good to me, but I’m no expert. They measured dead on with the advertized dimensions. I took some quick comparative lux measurements. Cells were not fully charged to start and were not recharged between measurements. I did several measurements, switching lenses between each measurement. This was not precise measuring at all. Just a rough comparison. The below are averages.
With a JM26 (58mmx2mm), I got the following lux measurements at 10 feet:
Stock 9080
AR Lens 9780
Increase 700
7.7% Increase
With a mystery SRK (55mmx3mm) at 10 feet:
Stock 1982
AR Lens 2130
Increase 148
7.5% Increase
With a old stock C12 (42mmx2mm) at 10 feet:
Stock 3720
AR Lens 4050
Increase 330
8.9% Increase
I can’t seem to find a working 27 mm lens light tonight.
Here are some camera phone pictures:

Thanks ImA4Wheelr. They look good going off your figures. I put one in my rebuilt 2 x 26650 HD2010 and it certainly hasn’t cut the light output. Yes I’m a fan also.
Those numbers look quite good to me. Thanks for sharing ImA4Wheelr.
Waiting on the 64mm for the 3C (now 2-18650) defiant.
Any chance of 37 mm x 2 mm?
Thanks for sharing your results Ima4Wheeler.
How would people say these compares with AR lenses from other vendors out there?
Seems like these are great bang for the buck, and also available in many nice sizes!
Just ordered 5. 27mmx2mm for Solarforce L2’s .
Damn CNQuality goods, they’re so tempting, I nearly bought another flashlight - brassy thing and/or they look so handy !!
It’s always the same when I visit there.
RIC - will these AR's be available via fancyflashlights.com? I don't see them listed there.
Here you go. l found them in the new products section.
What about more than 5000 of Jacob A60 owners? Rick consider this AR lens size also.
Thanx there mrs! Damn these are cheap, $1.50 free shipping from my VIP account, and looks like they are legit true AR lens from ImA4Wheelr's tests. KD and FT supposed AR's are worthless. I got to add up qty and size of what I could use and put in an order. Basically it's 4-5 for the price of one UCL.
I'm thinking that 58 x 2 lens should fit an A60 fine. I used a 59 x 2.25 UCL/p lens from flashlightlens.com, and it was too tight and had to file it down a bit. Not sure bout the thickness - someone should measure the stock lens, forgot what it was...
Tom E are you sure? You did some wrong measurements :bigsmile:
Jacob A60 has 49,7mm lenses or 1,96 inch, thickness 1,9mm
It should not be smaller or bigger than that if you ask me. Because Jacob rubber lens holder is for this dimension.
So Rick if you can order 49,7mm AR lenses for true flashlight gem and one of the best thrower reflectors ever build Jacob A60.
Ooops! Yes, you are right! It must have been the 52.1 mm UCL/p lens I filed down. You really don't have to be so precise though - there's some slop. a 50 x 2 mm lens would be fine, I'm sure. If I was able to jam in a 52.1 mm lens with very little filing, a 50 or 51 would fit. I struggled with that filing and ended up not getting much material off, but did scratch the lens 
. Actually some replacement lens at different sizes fit better than stock lens - 1mm one way or the other is typically fine, but still best to measure and see for yourself.
Tom E,
Probably 50mm could fit(knapp) but it will stretch stock rubber holder a bit.
You are old member of this forum so please you should tell Rick to get Jacob A60 lenses. I think we will all follow you.
What size they should be 49,7 or 50mm?
I will surely ask him, I'd have to measure when I get home, but I'm thinking 50 mm would be fine. I know the one I'm using is over 51, but I'll measure all this - I got one mod'ed and one stock Jacob right now.
There are LOTS of Olight S10 and S20 owners out there who would love to have a 19mm x 1.5mm lens available to replace the green tinted stock lens.
Please check and then tell the right size for Rick.
P.S.
U can fit 52mm but it will not sit in stock rubber holder. It will be above it.
Hope you know what I mean. Please pay attention on that rubber holder and the way it holds lenses.
On mine Jacob rubber holder perfectly surrounds diameter and thickness of stock lenses.
