It's interesting - the XHP50.2 3V has been out for quite some time, and I got a few lights using them, but never really tweaked them up, mostly leaving them stock, or they were triples, or some other odd setup. So I decided to mod up a couple and see what a single XHP50.2 3V, single cell light could do. I modded up the WT1M w/spring bypasses and better LED wire.
So on a T42 it does 18.6 amps, 5210 lumens at start, 4550 lumens at 30 secs. So the EC06 results sound more reasonable now. Take 5210 x 6, result is 31260, so to get 28K on the EC06 is realistic, 1 cell and 1 FET per 2 LED's. The WT1M's FET is probably not the best either, pretty decent though.
You cannot use a magnet or even a piece of brass because if they come into contact with each other, everything will burn! You have to use the Convoy 3x21A flashlight adapter, write a private message to Simon Mao and ask him if he can send it to you, he was very kind to me and sent me 10 by paying through his shop in AliExpress. Or you have to create button top batteries starting from the flat tops and you have to use a 21mm PCB board that you always find on Simon Mao's AliExpress store, fix them with a soldering point and protect them with a shrink film like I did. The choice is yours...
Others are using the P42A cells. I just ordered a set for my EC06. The tops stick out just enough to make contact. CM2010 uses them and said they work fine.
All flat top batteries I’ve used worked fine without an adapter. 40T and P42A, I know you can’t use the Yellow Vapcell because the positive sits below the body of the battery.
Best performers? Are you looking for the longest run times or max output? In a torch like the EC06 able to put out so much light it would be hard to tell the difference between 26k or 28k with just the naked eye. Between the 40T 30T P42A and the Vapcell T42 the difference is so slight that your best bet would be to get the cells you like. I own all these cells and find myself always using the 40T’s. They are less expensive then the vapecells. The reason I chose the P42A’s because they work, so I don’t have to purchase the battery plate from Simon and wait another month or so.
I'm trying to buy a bunch of Vapcell T42's via alibaba. The place I'm dealing with quoted me a great price for qty 20, shipped, but we'll see - deal isn't done yet and wondering if she got the qty confused because it's about 1/2 the price I'd expect, even for wholesale cost.
Wow, yes very unusual to see this (or any light) underrated by more than 10,000 lumens! I suppose it being direct drive makes this possible.
Surprising that Astrolux would underrate the advertised output by that much.
Your measurements combined with the GB price are steering me towards this light over the Acebeam X45 (4*XHP70.2 / 18000lm)
Looking forward to seeing someone else’s measurements to confirm this.
