Led4power.com : LD-4 CC linear drivers, ILC-0/1 illuminated tailcaps, optics, MOSX, copper DTP MCPCBs...

I do not care about the weight. My point is that copper can be soldered. Then the led board does not move and it’s perfectly centered. And that’s always very important for me when I make multi-led.

Below is an example of what I mean:

I would think the switch could be a simple momentary FET Driver with only one mode to place in every Flashlight instead of the clicky-board.

Perhaps it has LEDs for iluminated tailcap and a bleeder resistor on the main Driver is needed. And this switch can be used as upgrade in each clicky Flashlight.

Perhaps short klick for mode Change, as reverse clickies behaves and Long click for power off.

Thats what I would think.

Spacer is too wide.

My switch is FET, no clicky and no coin battery, compatible with Convoy S and M lights, and EE X6(other light if there is enough interest).

1.mosX board are aluminum with ceramic insulation, so you can't solder them.

2.Soldering copper MCPCB on such big spacer would be very difficult and there would be great risk of frying/damaging LEDs from excessive heat.

3.It's not good if pcb doesn't move in this case, all parts have their tolerances, so it's better if pcb can move a little bit, optics have 3-4 legs, so centering is always perfect. For example ANNA optics fits very tightly into C8, if you solder hypothetical copper pcb on copper spacer and make just 0.5mm error, optics wouldn't fit into head.

I would buy it anyway. However, thanks for explaining.

So with a cap? That’s great!
I would like to use it in a convoy C8 tailcap (together with the Ciriba-ru C8TT head).

You can ask Kiriba-ru for custom copper spacers.

Can you check if the height is right? If so, I’m willing to mod the spacer to fit if it’s only the width. If it’s both width and height then it’s better for me to make my own spacer again.

I think measuring manta rays reflector is more easy. If it has regular C8 size reflector, then required spacer height is same to convoy.

You’re right, that would be easier, lol. I believe they both use the same sized reflector. I also noticed on led4power.com that a future listing for 30amp switch is up already.

Hi Neven,

Can you already tell us something about this new product?

Thanks!

Can I use your LD4A driver for a triple/quadruple UV light with the Seoul Viosys Z5 365nm or on a single LED light with Seoul Viosys CA6868 (4 dies in parallel @ 3.7V looking like a 7070 XHP footprint)?

These LEDs has a quite high Vf of 3.7V and I plan to drive the LEDs to its limits/highest mode only. If not, can you recommend something more appropriate for UV LEDs?

Thank you!

Ist a momentary switch which uses a Little FET driver, which can be exchanged with clicky switch.

I will have more information in a few days.

I don't see why not, UV LEDs have high Vf, so that limits max. current, but also power dissipation in driver is smaller, so you can use LD-A4.

.

It's a 30Amp illuminated FET switch.

Lol, ok. I saw it on my phone and I thought that the switch was a led.

- I deleted my post, so it doesn’t confuse anyone.

More details please. Can it be used in almost every clicky flashlight?
How to emulate a short and long click on a reverse clicky with this switch?

Shorts specs:

*0.7mOhm FET, bottom pcb and fet drain is soldered directly to brass case, this eliminates additional contact resistances (those can be higher than FET resistance itself) which are present in classical PCB-retainer tailcap

*ultra-capacitor as auxiliary supply - practically unlimited life,reliable,fast charge, no need to replace it unlike coin batteries

*0-600uA Constant current channel for illumination LEDs

*Press-button momentary switch

*Configuration mode - adjustable illumination brightness, switch UI style, lockout, short-long time threshold set, factory reset.

Switch style 1 works like this: short click changes mode (short-long time threshold can be adjusted in config. mode,default is 0.4sec), long click turns flashlight off. From off, flashlight is turned on at switch press.

Switch style 2 works in the opposite way, short click is on-off, long click cycles through modes.

Entering into config. mode is done by holding switch from off for few sec and entering password after that, config. mode is very similar to LD-x4 config. mode, with table based menu/sub-menu.

For now I plan to have versions for Convoy S, M, C8 lights (with rubber tailcap), and EE X6 lights, also can be other lights which have compatible Convoy/X6 tailcap parts.

I can make custom versions for some other lights if there is enough interest.
