[1900k edition is in!] WTS: 1900k-5800k 5mm LED 95+ CRI

Thanks. I received an email from Paypal this morning reporting the invoice has been updated with tracking info.

Yes Nismo I love seeing new ideas. And I just got my own bag to try my hand at a few.

i received some today! i like these a lot. :+1:

I’ve got 2 of these:

28 LEDs
With a modified tail switch it can now both tail stand and fit an 18650 (unprotected though).

And one of these on the way:


21 LEDs

Should i get one of these too?

:laughing:

That 9 LED ones will most likely run unregulated with 3*AAA batteries. I’m not sure if I can recommend those.

They all run direct drive form 3x AAA in stock form.
So they need drivers, or at least some 7135 current regulators.

I used 12x 3400K rngwn leds to mod a Singfire 812A.

It is old stock, it seems they have not sold them for a couple of years, there was rust on the spring and even inside some of the 5mm leds was corrosion so their warehouse conditions are not optimal.

Nevertheless the build quality is a few grades up from what I can buy in the local stores for two euro’s:

*the ano seems really nice, not cheap at all

*the switch is press-fit but easy to disassemble (I swapped the black 16mm boot cap for a better quality orange one, soldered the loose spring to the switch-lip and made the press-fit a lot stiffer with a solder blob on the other switch-lip that presses against the housing).

*the head assembly is not press-fit but closes on the inside with an actual screwed-in retaining ring (I made two grooves with a saw in the ring to ease opening and closing, and there was no o-ring at the (plastic) lens so I added a nice orange one to match the boot cap, the rest of the light is o-ringed so now the light is submersible)

Then I swapped the 12 395nm leds for 3400K 95CRI leds and that was that.

With 3 AAA alkalines (one was not even full) I just measured 113 lumen so the leds are properly driven at ~30mA each. Tint out the front in the hotspot: CCT=3170K, duv=–0.0025, CRI=97.3, R9=85, R12=92, Rf=94.3, R9=102.6. The beam is a smooth flood.

Yes, there should be several available on eBay that are similar, but I got mine from Clas Ohlson (swedish hardware store) Link to the lantern.

The frosted glass is from another lantern bought at a local hardware store, one of those flickering flame ones. I didn’t like the color and animation of it so I’ve used it for parts.

I have modded the 9 LED 3aaa flashlight to add a 7135 regulator. The 7135 + & - pins will straddle the traces on the LED mounting board. remove the center pin and solder a wire from center tab to feed spring. …now isolate the spring where it normally contacts the outer trace on the board. I added insulator then glued it to the board. (My favorite shoe goo for that!)

Nice. :sunglasses:

I have one of those 12 LED ones too, and a silver one which is a bit different, but both have screw on heads.
The black one is about 10cm tall.
This means that is is possible to use an unprotected 21700 and a tail-stand-able tail switch, if you superglue the spring directly on the back of a small Omten and use a switch boot without a nub, and epoxy it all in the tail cap. :slight_smile:
A single 7135 on the back of the LED board would be enough (29.2 mA per LED).

I’m gonna order one of those super crappy yellow plastic 9 LED ones too, just for fun. :smiley:

I modded a few 2-AA and 3-AA small Hurricane LED lanterns like that with generic WW LEDs, but these 2300K 5mm LEDs are high CRI and much closer to a real flame tint. I also found a bunch of small 2-AA ones at a local dollar store to mod too. (photos and mod topic eventually coming.)

I’ve searched local and online hardware stores in Norway for 5mm hurricane lanterns, I’ve only found the one I modded that has 2xD batteries. I don’t mind the D batteries since they last a good while, but it would be nice to use some Ni-Mh AA since I’ve got loads of them.

I’ll keep on searching though, would be nice with something smaller and more compact. I’m also scavenging eBay and AliExpress.

The big issue with using the NiMH AA cells as 2S, is their nominal voltage is two low, ad below the forward voltage of the LEDs. (for NiMH you need to use 3-series with a 47 ohm 1/4 watt resistor to get the correct output. 2AA Alkaline cells have a higher voltage and can run a LED without a driver, (i use a simple 7.5 ohm resistor in series with the LED for running 2 alkaline or ZincCarbon cells.

Is anyone in the US who has received theirs able to post how long they took to arrive?

Mine have been listed as sitting at “SUVARNABHUMI MAIL CENTRE” for almost 3 weeks now.

Now that you mentioned it, there are some people who has already received the package despite it’s being shipped later.

It’s probably time for me to start a formal investigation with the post office.

One thing to note is that Thailand Post usually send the mail to two different U.S. airports; one in New York and another in Los Angeles. As of now, the mail that moves fast are the ones that appears in NY.
There’s a possibility that the LAX is jammed with packages those packages are the ones waiting to be scanned as “Processed Through Facility”.

Nonetheless, I will start launching an investigation.

Mine was shipped Dec 12 and I still haven’t received it in NY. My last shipment took about 2 weeks as I remember. I’m not too worried about it, as I also think the volume of shipping this time of year may be delaying things a little.
Edit:Just went to the mailbox and they are here! Thanks rngwn!

Still haven’t got them here…

If I’m dealing with lost shipments for that whole 1 Dec batch then it’s going to cost me dearly :weary:

I think they will arrive eventually.
It’s the end of the year, millions of packages are shipped, normally takes 1 to 2 months, we’re at 23 days since i paid you.

I did receive the 4000K 16-die led last week, which was really quick, so not all packages are on hold, some slip through.
