I’m really not too sure on how to decipher the bins…here’s the link to what they have in stock.
Alex, that’s exactly why I don’t buy emitters from digikey or Mouser, they sell a group bin and you can’t ever rely on what you’re going to end up with.
Where do you usually buy yours from? Trying to figure out the bins gives me a headache…
I get mine from digikey, I just order the easywhite bins, they are all within a macadams ellipse, so you at least know a range it will fall in. All the different color bins are too much for me to worry about, so far I haven’t gotten anything I didn’t like.
I ordered 3 5700k N4s the other day and put one in a MT07 and did a resistor mod…turned out nicely.
I buy emitters from Richard, or Cutter, or LEDDNA and occasionally from Intl Outdoors. Probably won’t be buying from Cutter though, everything just got out of hand on that end.
No, they do not sell group bins.
The part number describes exactly what bin it is.
XHP70B-00-0000-0D0BP250E-ND
for example, this is LED is chromacity group 50E, min flux group P2, CRI group B (70 cri), etc etc etc
All you have do to is read the data sheet and scroll down to page 22.
Or you can literally just sort by lumen output or CRI or whatever spec you want directly on the digikey/mouser website by clicking the top of a column.
For non 3 or 5 step easywhite leds 50E is group tint which can contains any from A/B/C/D tint with fixed color temperature.
Richard, any chance you might get some of the black E2L Jaxman hosts?
What’s the narrowest/thinnest 26650 cell available?
I got a couple of cheap flashlights in “blunderbuss” style (7-emitters, 3-cells) that are bored out just too narrow to accept my EVVA cells (the shrinkwrap would peel off if I forced the cells into the tube).
They bundled 18650 cells in those plastic sleeve carrier things, which fit the tube loosely. But I’d rather use the larger diameter cells if I can find some that fit.
See if 4 regular C cells would fit.
I’ve got a 2×C light that I hoped I could stuff a 26650 into (with spacer). Nope, juuuust a little too snug.
So 3 18650s with sleeves might roughly equal 4 C cells.
Purchased a Convoy C8 Flashlight Host - Clear Anodized from RMM on 06/13/2017. Very nice host. Accepts all my protected 18650 batteries with no problem. I recommended this host.
Maybe Basen 4500mAh . 26.2mm max diameter
Regular “c” alkalines do fit, with some space around them.
Looks (lacking a caliper) like 26.5mm bore diameter.
Thanks for the suggestion of the Basens.
The new quad board is a great improvement over the Tpad board. I was curious and had to order it and put it into one of my P60 pills. The beam is round and i think it throws much better as well.
No regrets! I bought a P60 from Vinh awhile back and I now have to take that apart and reflow the LEDs to the new board. Will order more in a bit.
Hello RMM,
Question about your EVVA branded Panasonic NCR18650B Protected 3400mAh cells. I purchased one late last year. The description on your website mentions that low voltage protection will kick in at 2.75V. Recently, I had mine down to 2.51V, and it was still running. So, is my PCB broken or is the low voltage limit actually somewhere around 2.4-2.5V, like in most other PCBs of this kind?
Wondering where the 2.75V value came from. I don’t see it mentioned on evva-tech.com.
Hey I was wondering about the 32mm HX-1175b1 - 7A Buck Driver.
It says in the description “not recommended for 1S LEDs!” but from what I can find online it is designed for the SST-90 which is a 3v LED.
Other than the high 7A current it should be able to run 3v LEDs fine, right?
I couldn’t find any info online about it, other than Richard’s store. It looks like it is recommended for ~6V emitters. Maybe there was another version of the same driver that’s made for ~3V emitters. I can imagine that a SST-90 might survive on this driver anyway, since those take an enormous amount of power without blowing up (compared to our “usual” ~3V emitters). You could always try it and let us know the outcome. :innocent:
This is where I checked: Driver Info: HX-1175b & HX-1175B1 (Pic Heavy)
Reading it again it seems like the b (not b1) is for SST90 3V leds.
I guess the B1 or C models are for 6v output only nvm I was wrong, it works for 3v
.
I hope some day MTN electronics gets buck drivers that can do more than just 6A on a 3v led…
Closer to 2.5v most likely. Take it down below 2.5v and see if it trips.
