On 16650, you can see a little step down after a few seconds once the voltage drops a little. Not to low level, but to my eyes a few 100 lumen drop. Still plenty bright, but as expected, 16650 cells cant handle the amp ask of the drop in.
Can someone recommend a source of ‘wide enough’ copper tape for thermal wrapping dropins?
Just got a couple new P60 amber triples from KD, but I’ve run out of copper tape the right width.
Maybe try “Randy PFlexPro” Brogden. You don’t want to use the copper tape with the glue……I don’t know if you seen this yet Hank, little tips and tricks for wrapping drop in’s…
I have an ancient Pila GL4 that takes 2x18650 or 4xCR123A. I’m considering a Sportac P60 drop-in to keep it going. Voltage wise, it seems that I’d have to go with one of the 9v max drop-ins. Pila quality is excellent, so I’m hoping the tailcap is good enough.
I noticed the Pro version puts out about 300 more lumens. From the default info provided it looked to me like protected cells were required with “Pro” version and not with the standard… but expanding the info, I see it stated that button top cells are required. So basically you must run these Sportac P60 drop-ins with protected cells.
About HD compared to HI… what’s the temperature difference?
They (sportac drop ins) have a little plastic polarity protection ring, only thing to make it require button tops(and protect). I have snipped mine off on most of my sportacs(of course extra care required). So i can use flat top cells, as most of mine are. The older single mode 219 triples are 9v iirc, the 2 mode 6v. So older ones should be fine as well.
With the latest xhp35/HI, single and dual mode will take up to 9v, i have tried it with single 18650, 2x 16340 and 2x 18350 cells. No issue with any.
Used mine last night out walking the dog, lights the way nicely(i have the HI NW) and throws light easily across the field(maybe 200ft or so). Will obviously throw further, but its decent usable light and plenty in the spill as well.
Google “copper slug tape”
Yes, it is a barrier against slugs. They can’t stand it.
As it seems some “know it all” but really know nothings, like to lecture us here with their wit and wisdom, and delight in telling us that our interest in these practical things is, lets say, misguided. Even when they have absolutely no interest or knowledge, or understanding of history, the reasons why these things continue to exist, the pros and cons of primary cells, nor knowledge of competing products, to contribute. What a waste of effort.
But they might be repelled by a barrier of slug tape, if there is an internet equivalent.
By the way, there isn’t much difference between Al and Cu, when you study the numbers (or just try it out yourself). A good wrap with heavy duty cooking foil will usually do the job, and is easier.
For less air pockets between the foil wrap. Strips of soda can work with the 24 ounce ones slightly thicker. Usually only one layer can fit and it’s usually snug if you find the right beverage can size. Copper slug tape that’s a new one for me, thanks.
I received yesterday the Sportac xhp35 HD . I’ve got a PflexPro 3.8 amp with a Cree XPL V6-3D 5000K. Sportac is brighter and only slightly cooler. I’ve destroyed the current portion of my cheap meter so no current reading for now. Took two full small aluminum can wraps, but it’s tight.
