I am not seeing any pictures?? I assume you meant to have the heat maps for the different times included, yes?
They were working for me yesterday? I did have some issues with the forum not liking spaces in the picture names (in the links) but fixed that.
No pix here, either, but for me that’s not unusual, so I didn’t say nuttin’.
So I couldn’t see them on my mobile, but on my PC they’re there. Are there any site specific pic size limits or anything like that?
Have any of the above pics worked?
Gnope. Works when I plug
into the location bar, but not even in “<img …>” tags in previewing a reply.
Okay, that’s strange. It wouldn’t work for me with any spaces in the links, but after fixing that the pics appeared for me.
The fairly average job done by the manufacturer with heat sink adhesive
The end result after using the heatsink pad 0.5mm sheet - which turned out to be a putty type material.
FLIR pic with light off. It’s on ceramic floor tiles which are fixed on the house concrete slab. I didn’t lock the FLIR temp range- so for each pic the same colour will represent a different temp.
40 secs after turning on to high setting - previously I couldn’t feel any temperature difference after a couple of minutes. Now I can feel the heat almost straight away.
2 minutes
6 minutes
Spewing my absent mind didn’t think of using the FLIR prior to applying the heatsink putty.
If I do any other P60 flashlights I’ll be trying the copper foil. You’d get the added bonus of an extra current flow path via the copper (providing the host isn’t anodised internally) and it’s got to be easier to remove. That XHP50.2 drop in is fantastic for output so I’m happy to leave it permanently in the E6 21700 host, I actually bought the E6 21700 just for that drop in. My other P60 host is a cheap Ultrafire.
Nothing in any of them here. Just blank posts, Using Win 10 with Chrome. Fully updated…
BTW, I normally do not have any problems with images on the forum.
Windows 10 with Firefox 105.0.1 64-Bit here, no problems seeing all the pictures? 
OK. Thanks for your effort. Now I can at least get to the photos. I have a couple of the E6 21700 hosts, but with lower output (1000 lumen) KD drop ins. I got some copper sheet that I cut to fit. To the point that the drop ins had to be forced in with difficulty. A bit tedious for sure… But they barely get warm on high.
I put the drop in similar to what you have (50.2) in a Fivemega 26650 body. Using an Orbtronic 5750mAh Li-ion 30A cell. Bypassed springs. (I need to check the current on day) I Used the same copper strips press fit. It also does not get very warm. But there is lots more thermal mass.
Problem is by having to press fit the drop in to the body, it is difficult to change them. Similar to the “putty” that you used. I have some in my cart at Amazon, I may give it a try. Will not be as good as the copper, but easier to install. I wonder if it is practical to reuse it when changing a drop in ??
I’m not sure if it would be reusable? If it stays the same consistency it could be. I checked in the battery end of the E6 21700 and none is visible, so it hasn’t gone soft/ moved after running it for that test. I also put some normal heat sink grease onto the threads of the brass pill before fitting the reflector- seeing as it’s the reflector that the putty is fixed to. It would be interesting to test the copper sheet vs the putty. I couldn’t find any local places to get some copper from so went with the heatsink pad/ putty.
I noticed comparing the E6 21700 to my cheapo Ultrafire WF501B that the E6 doesn’t have anodising in the body where the drop in fits- the Ultrafire does. So you could possibly improve the battery negative contact with the drop in using the copper in the E6.
The WF501B has a Cree MCE drop in that’s running at around 2800mA at the tail cap. It doesn’t get very warm. (I’ve got a Samsung LH351D in 5700k on order to replace the MCE. Something else to play with/ mod using the same driver. If I like the result I might get another E6 21700 to fit it in.)
If you have access to Amazon in AU, you can find copper sheet there.
I bought THIS
And some of THIS as well.
Sometimes I need to use some of each to get the right fit. I probably could make it a bit loser than I do, to make it easier to change the drop ins. Snug fit without having to use a rubber mallet to get the thing in, would have to be much better than air… as it is with nothing added.
I did come across that on Amazon. The price basically doubles when freight is added on and the Aussie $ isn’t doing so well ATM.
That silicon pad was off Amazon Australia and was AU$6.99 delivered (~US$4.50.)
The reality is - price wise - it doesn’t make a lot of sense fitting a highish powered LED into an expensive P60 host, then doing mods to improve the poor thermal performance (that make it too difficult/ inconvenient to bother change the drop in.)
It would be smarter buying something like a Convoy M21 host to begin with. There’s not much difference (for me in Australia) between the M21A host and the E6-21700 price. I’m not sure how close they are size wise? I do like the ability to use the more powerful 21700 batteries in the E6 21700.
The P60 system is old, out of date and isn’t as efficient as newer systems. So am I. I’ve got lots of P60’s in 18650 and 21700, even a few in 26650. Under 2 amps almost all dropins are just that. Run it hotter and pack it tighter. I’ve got a 12-7138 chip XHP-50.2 3v running 4.5 amps, 6 amp triple XP-L2 and a few others. It’s the system that was the rage when I got into lights and it’ll be my go to for years. Properly built they can take hard abuse and rehoused when thrashed a bit too much.
Long live the P60
