Isn’t 12amps too much for a triple 219B? Did it run fine? How many lumens were you making?

MascaratumB · November 12, 2018, 11:13pm

Forgot to let my feedback on the things received! All good and some are already in use

BTW, it took me a while to figure out how to operate the driver configuration, but then it was all full speed ahead!
I’ll be getting some more soon and other stuff as well!

Thanks for you work :+1:

Ordered 10x Luxeon V2 4000K 70CRI from DigiKey, excited to try these out. I think the 5000K versions will begin showing up in less than a month it seems. I’m sure LED4Power is already on top of this

The original 4040 Luxeon V has one of the most evenly tinted beams of any LED I have seen so if this is remotely similar it will easily become my go to 70 CRI LED choice for 3535 footprint.

I am not too smart.

6×0.5mm Gold Plated Brass Button Contact

This means 6mm not 6 contacts. Public service announcement.

Don’t feel bad, I made the same mistake because I added this item at the last minute and did not pay enough attention :person_facepalming:

MascaratumB · November 15, 2018, 1:29am

… +1 :person_facepalming:
I was expecting 6 and only 2 arrived! I should start reading things carefully
But I didn’t need them yet

LOL. Glad I wasn’t the only one.

Maybe L4P can update the description for us and create a “discount” pricing tier

MascaratumB · November 15, 2018, 1:57am

Yup, adding a 2 x “6mmx0,5mm” would be more elucidating

I have one doubt about the LD-A4! I am using mine with a foward clicky switch on the OTR M1!
I have it configured with Moonlight + 3 modes, with the 2x clicks for Turbo.

However, when I double click it (half press as it is a FC switch), it doesn’t assume the “go to turbo” most of the times!
Also, sometimes I have to click 2 times after being on “momentary” moonlight so that it goes to turbo. Maybe this is related to being a FC instead of a reverse clicky switch?!

But another strange thing happens! Imagining I am on mode 2 (low, after moonlight) and I double click (half press), it will go to mode 4 (turbo) but it always take a bit longer on the mode 3; meaning, from modes 2 to 4, it always passes and “waits” on mode 3 to slightly step up to 4…

This happens both with FC and RC switches. Is this normal? Or can it be related to some bad installation I might have done?

Thanks and sorry for the confusing questions

Agro · November 15, 2018, 6:39am

Actually I fell for this as well.

led4power · November 15, 2018, 9:38am

Changed listing to "6mmx0.5mm (DxT) gold plated brass button contact" to prevent further confusion.

It's difficult to mimic reverse clicky with forward clicky switch, mostly you can do only simple operations.

kikkoman · November 15, 2018, 10:03am

L4P, are you going to sell the Luxeon V2?
I’ve noticed it’s in stock on Digikey and Mouser.

led4power · November 15, 2018, 11:09am

Maybe later, reels of V2 have 2500pcs, not the usual 1000pc.

Osram KW CSLPM1.TG (2mm2) is available now:

https://led4power.com/product-category/leds1/osram/

Kills XP-G2 in throw, while having 1500lm+ output, which is great for factory undomed 2mm2 LED with pure white tint. Vf is ridiculously low, 3V@3A,3.13V@5A,3.3V@8,5A.

Agro · November 15, 2018, 11:37am

The 3rd best bin this time.
Can’t wait for more precise results to know what the 1500+ actually is. Q8WP was just as throwy as Black Flat. This one would need about 1900 to compete with White Flat.
That Vf is truly extreme.

kikkoman · November 15, 2018, 11:40am

My error, Mouser doesn’t stock it yet, but Digikey offers the following quantities (L1V2-4070000000000):

- 1000 $0.8464

- 500 $0.8667

- 250 $0.9750

- 100 $1.0834

- 25 $1.2460

- 10 $1.6790

1 $1.9000

Thanks for the answer mate! My suspicions were correct! I will probably get more but to use with RC switches!

About this, and sorry for the dumb question, does it mean that using this led above 3A will not produce a) so much heat and b) so much battery drain?
I am planning to use one in a 16340 flashlight with a LD-A4 driver, but I’d like to know if it will be better to use it with a 2A-3A or 4A-6A driver!

Thanks in advance :+1:

Hi,

would the combination of MOSLED EXTREME ( MosX ) Ceramic Insulation XP 3535 MCPCB work with the OSRAM KW CSLPM1.TG – 2mm2 LED soldered to it?

Thinking about upgrading my XP-L Hi Convoy C8.

With a linear driver like LD-A4 Vf doesn’t affect heat/battery drain but only how long will it run before output starts dropping. With a buck driver it would be more efficient.

Thanks for the answer Agro! Getting a buck driver with a nice UI as the L4P drivers is something I don’t see as possible currently, so…maybe I should stick withe 3A driver to avoid major drops. I believe this LED will give a nice throw under a zoomie lens !
Thanks again !!
