18500 is shorter than 18650, but the same diameter. 18500 is 50mm in length, 18650 is 65mm in length.
AA batteries are about 50mm in length, so an 18500 is about the same length as one AA battery, but thicker.
Hi Jaxman,
Do you know if a protected 18500 fits with the 18500 tube? Or will the battery length be too long?
Wish I was able to offer an opinion but they were sold before I could get the funds.
Please continue to sell these as Hosts for the long term.
I have build up an E2L from host to flashlight tonight. My conclusion is that the E2L host is nice but not perfect. Miles easier than converting an S2+ in a triple though.
What I found that needs special attention from the builder (and could be improved by Jaxman) :
1)the ledboard needs a generous bevelled edge on the underside to make it sit flat on the shelf (I used a small diamond file). This is because the ledboard is exact the size of the head opening while the side of the shelf is bevelled a tiny bit. Once you succesfully have done that, ledboard and shelf mate quite perfectly. (btw, Jaxman left a brief note in the box trying to explain this but the note is not really clear)
2)the holes for the optic in the MCPCB are too narrow. You will get the legs of the optic in eventually but it is a royal pain to get there, I even used gentle whacking with a punch and hammer one by one on top of the legs to get the optic fully down (and thus leds in focus). This is a serious opportunity to damage the optic and if you are a bit more clumsy: the leds. When building up the second host I will ream the holes a bit before reflowing the leds, so that the optic will go in easily.
The rest of the build went smooth. I used Nichia 219C 4000K R9050 leds (from Rey), a Banggood bistro driver (with fix), and made a lighted tailcap. Because of the low Vf of the 219C I made no spring bypasses and the ledwires were thin (24 AWG?). The output on highest setting (30Q battery not completely full) I measured at 1930 lumen at switch-on and 1660 lumen at 30 seconds.
Nice foto.
Thanks for the detailed info djozz. lt should be a good help to us others here.
hi djozz,thanks for your topic on building E2L. I want say below:
Now the on sale E2L is the 1st version, so there maybe some little problem. As the points you have metioned,I give my answer for dear all.
1,the MCPCB is hard to be put into. We have recognize this, and next batch we will enlarge the place to fit the MCPCB.
2,as the holes of MCPCB, we designed the MCPCB holes according the lens strictly, we need a solid fixation, so we never want change it. We found we can assembel it very well. You can try more times and find a good solution on assembling the Lens on the MCPCB. I think since our workers can do, then deal all must can do it too, ever more better.
3,Other lamps including the Nichia 219 series will be availble in future. Becase we have inquired Nichia Company, they have not 6000k Ra=9050 led. Now only 4000K.
Thanks for your great work.

4000k is excellent!
:+1: … Well said. 
where’s that explained?
Great summary, thank you.
Guidance on making the lighted tailcap would be good to point to; good to know these lights can definitely support that.
I can’t wait to see this beauty in black. Glad to hear that’s on production!
I hope that i can get a Host on Aliexpress soon because ordering from MTN is not a real solution for people from the EU (15$ shipping). I was planning to mod a S2+ with 219c´s that i have already here but the EL2 looks much nicer.
I have one grey host leftover and would like to wait for the black host to appear, I could get it to you for cost price if you like. Shipping should be 2.5 euro.
…If theOnlyDocc doesn’t want it, i would like to buy the host from you, Djozz.
I actually prefer grey.
By the way, it’s very nice how the bezel doesn’t shroud the optics at all. :+1:
@djozz
Thats sounds nice and i would prefer the grey host! How much is the Host? I can not find a Host only price.
may be TAN
I payed 35.38 euro for two hosts, divided by 2 and 2.5 shipping added is almost exact €20. I will get you my PP via PM (or you may have it somewhere because of Clemence’s leds).

friend, we like to provide kinds of tints for one model…we would not let buyers have no chice on Tint.So we at least sell 2 kinds for every model Jaxman lights.
Black version will be ready in about 30days.We heard that many buyers like black body,so we decide to produce black version.
Nice! And i take it if you can wait till Friday. I checked and i have your PP info from the last LED buy. Can not wait to put the 3*219c´s into this beautifull host.
