ah ha! the wire size to the S70 is 18awg, and the wire size to the L6 is 22awg. remembering that i tried to solder 18awg on the L6 but couldnāt do it as it kept shorting with the reflector.
Oh cool! Itās good to know that 22ga can cut exactly 1.5 amp over 18ga.
A trick you can do with the wire is get the solder liquid and then remove the iron and quickly press down on the joint with something flat and metal. It will flatten the joint so that only the insulation will touch the reflector.
Installed my 30mm driver in the L6 today with an XHP70.2 M4 30G 80+ CRI, and a lighted momentary switch. Loving narsil. I did have to file the driver edges slightly to get it to fit the driver pocket, but no big deal. 18ga wire. Havenāt measured current yet, but its super bright. The L6 reflector also blends the tint of these new emitters well, I dont have much color shift at all in the beam.
Is that built on a board or MCU on itās own?
Either way is fine, if just MCU on itās own Iād still need a 30mm board and then I could get the rest of the parts myself, unless you would supply the rest as a kit? I donāt mind either way so long as Iām not messing you about, itās very decent of you to even offer this
so i decided to change out the 18awg for 16awg on my s70, took me a while to figure out how not to short thru the reflector. now it draws 12.5A - 12.9A at the TC with fresh Littokala. but the wried thing is i think the color is shifting from bluish on turbo to yellowish at lower setting. donāt think i recall this before.
If itās starting to go bluish, then itās getting too hot. Make sure the star surfaces are making good contact to the flashlight body and that you have good thermal grease on there. The reflector should be pressing the star down with some force.
On my L6 I was using copper shims under the star to adjust my reflector focus, but it wasnāt transferring the heat well enough and started to shift to blue. I removed all shims and it stopped doing that.
took apart the s70 again, and notice there is a dimple center to the led hot spot!!
donāt think i can do anything about thisā¦ spread around a little more thermal grease, screw the reflector as tight can i can, still i am getting that bluish shift in color
What is this piece? Is it the edge of the copper folded over making a high spot or just thermal grease?
Does the color shift get Bluer and Bluer or does it stabilize? Because at high power these emitters do tend to get cooler in color but itās a stable color.
