I have done spring bypasses on a couple of lights in the past, but I read on here somewhere if you have a triple/quad etc it is really worth doing.
I have an Astrolux S41 and it has dual springs in the tail cap already - is there any benefit to bypassing these? should I remove 1 of them if I do? (there won’t be any room if I don’t?)
I have an S41… My double springs in the tailcap flattened out from heat while I was using the light on high for about a minute. I had switched to the 18650 tube so I guess technically it was ‘modded’ but not really.
To make it work again I swapped the switch and installed a spring with a bypass. (The original switch still worked, but it wasn’t right, had gotten really soft and mushy)
So there was enough resistance in my double spring to cause them to heat up and flatten.
It sounds like it is indeed worth doing. I have a few switches around so I’ll do one of them later on and see what happens.
Thanks for the reply. :+1:
My opinion is divided:
- on one hand I read a lot about additional Amps flowing through the wire…
- on the other hand I take a look at the spring in my DX80… a single one… for creating 32.000 lm…
A double spring , of a quality bronze or berrilium (not gold plated iron) , and about 1mm thickness ,should do the job , without bypassing ...
But this is a subjective option , IMHO.., as Winston Wolf noticed , 32K lumens with only one spring ! Quality is all that matters...
I prefer quality springs like those made of copper beryllium. Bronze is not a good conductor of electricity, but I think even those inexpensive carobronze springs are good to use in combination with spring bypass. They’re good not because they are better conductor of electricity, they’re good because of their higher tensile strength and they can take high temperature. These are the ones you want to use for your spring bypass.
The material matters much how good it conducts
Copper alloy springs are always better than steel, but pure copper conducts far better than even copper with just a fraction of a % of other metals mixed into them
If you would take copper from water pipe and make a wire from it it would be pretty poor compared to electrical copper, so also it matters if the bronze is made from pure copper
