Emisar D4S review

I was hoping Emisar would make a red backlight version. I am holding out until then.

As far as I have understood, those color-LED boards will be sold seperately in different colours?

Why not make a RGB-version, so people can set their preferred color themselves?

Ever notice how, when a manufacturer picks up the gauntlet and offers something new everyone screams MORE, you shoulda, you coulda, you oughta…… ?

Thank you Hank, well done! :slight_smile:

Red backlight looks sweet, I’m going to hold until new color shows up.

Personally I would’ve preferred a green mimicking tritium but brighter, but blue is pretty too.

I think the cyan will compliment the smooth green perfectly! :sunglasses:

Owner of this specific D4S said Hank custom made for him. However, when I e-mail Hank about the custom aux LEDs D4s, he replies “I’m afraid we are not able to offer such option.”
May it is just for China customer or for Hank’s group members only.

The aux LED board uses some common cheap LEDs and they shouldn’t be incredibly difficult to swap out. It’ll be useful to have hot air or a wide solder tip for unsoldering the stock LEDs though.

It looks like it uses the same type of LEDs as several of the clock kits floating around lately. I don’t know what type they are, but they can put out a lot more light than what the D4S does with them.

Sorry, are we still talking about lady toys?

Easiest way is to use two solder irons. Hold them on both ends and lift the led.

On the other hand it’s an excuse to get an hot air station :wink:

These LEDs don’t have much metal to grab onto, so I’m not sure the 2-iron method would work unless you have a third hand to grab the LED from the sides at the same time. That method works with resistors and capacitors, which typically have a metal surface to press the iron against, but I haven’t found these to work that way.

Putting them on the board is easy, but getting them off without destroying them is difficult.

This pic, when zoomed in, might show enough to explain why:

Solder wick might work!

The great thing about this design is that the secondaries are all on their own little separate board. So you pull the board out of the light, toss it on a hot plate/stovetop/frying pan/whatever, heat gently, then when the solder flows you just flick every one of those things right off. They look like 0805’s to me, same ones many of us use to build lighted tailcaps, so pretty easy to find in lots of colors to drop back on.
Obviously you’ll have to work kinda quick and watch your heat or you’ll be burning the mask off of the board, but I don’t expect it to be a very hard mod at all.

they are 0403 LEDs a lot smaller than 0805 (roughly 1/4 area)
but handable compared to 0201

Looks like Outdoor refunded the 26650 i purchased with the light, i know low stock was mentioned, but any one else or something to do with shipping to Australia. i noticed they are still selling instore.

LiitoKala store charges $27 shipping.

Then you need nothing special, a single soldering Iron + a blob of solder will unsolder these without any problems.

But if I look at this board - one resistor, 16 tiny LEDs and a very thin PCB - buying those in different colours should be very cheap

Ah, thank you for the correction. I’ve only got 0805 and 0604 on hand, so guess I need to place a parts order before my light gets here.
