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.
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?
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.
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.
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!
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 !!
Currently available I guess not! There is/was the AWT IMR16340 15C but those are hard to find!
Most of the cells handle 3A but not much above it :zipper_mouth_face:
