Firstly “hello everybody” from down under
I have been reading through this forum for a while now so I thought I better give something back
I have done this little writeup as there appears to be zero info on Led Lenser and POP Lite’s here.
I own a few different lights, and my latest one is a little Pop Lite, I was interested in the Led Lenser design as I have not seen any decent zoomers yet, and they are by far the nicest looking torch I have found, so I thought I would grab a cheap copy and have some fun with it.
The T62 runs a single 18650 battery, not AAA/AA like many others, this thing is tiny, much smaller than a C8, when I fired it up I was really disappointed with its performance, it was totally pathetic in terms of light output and clean light image in both flood and spot, had lots of artefacts and rings, off centre spot, very poor light indeed, soooo, I decided to dismantle this thing and “make it better”
Was quite easy to take apart, not as easy as a typical light like the C8’s as they use a glue on the threads of the “pill” but glue has never stopped me before :), once I stripped this thing down I discovered this one is regulated with a driver board unlike the AA/AAA brethren which apparently are unregulated, this board looks simple enough if you want to upgrade it, I chose to leave it in “for now” :), so I focused my attention on the LED module, this was a rather crapy little XR-E Q5, these modules are position on top of a aluminium shaft this acts as a heat-sink for the module, the white plastic you see when looking through the lens is designed to hold the module in place and to apply pressure, this aids in its heat transfer, I will add that they used close to zero amounts of heat transfer compound.
I had a spare XM-L T6 module sitting around so I though what the hell, may as well slap this sucker in and see what happens, I had to cut aluminium backing plate down to the same size as the XR-E package, I removed the factory cotton sized cable and replaced it with something more substantial, applied arctic silver thermal compound to the threads of the pill and under the module, soldering the wires onto the new module is the tricky part as the original XR-E has terminals on the bottom and the cables run straight down the side of the aluminium pedestal, the XM-L are on the top, but I managed to solder these cleanly on top to the actually led chips terminals and run the cables outwards were the sticker/logo would normally be, this was to prevent them from shorting to the XM-L’s backing plate.
Well after fully assembling and fire this sucker up, I was amazed at how much better and brighter this thing is, it now blinds you if even try and look at it, flood and focus are much better, hot spot is now central, spread looks more like a good aspherical lense now, much cleaner and consistent light, I fired this up and left it sitting next to one of my direct drive C8’s with an XM-L U2 in it, the C8 was definitely brighter but after 1 hour the Pop lite out did the C8, the pop lit was steady for 2hrs with no drop in brightness but my little C8 had drop way under the T62, all in all this mod was definitely worth it, the pop lite only got slightly warm were my C8 gets pretty hot, I did fire the T62 up with module off the heat sink and it de-soilder itself after a few seconds so it does push enough current to get an XM-l quite hot, this shows its internal cooling is good enough for a constant 2hr run with no problems.
After doing this mod this torch is my favourite, mainly due to its size, its flood is nearly as good as a normal aspherical zoomer but its spot stomps them completely, I love my C8’s as they throw really well for such a small light but they are far from pocket size, this little T62 is a great general purpose pocket or glovebox light, and after this mod it really competes with a C8 in light output, but the great thing is it still has fantastic battery life, oh and its a cool looking little torch as well.
I have a few photos of the mod and I will take some beam shots against my C8 XM-L T6 and my XM-L U2 along with a aspherical zoomer I modded with a 2900mah driver board and an XM-L2 U2 module, Ill try and get these up today sometime today.
I have a legit Led Lenser P7.2 on the way now so this will be the next thing I’ll pull a “Tim The Toolman Taylor” on
