Lumileds Luxeon V, test of a 4000K 70CRI emitter

How does the Luxeon V compare to the SST 40 as far as throw?

Now I have a Luxeon V without phosphor left. It emits UV as I learned. Which wavelength should I expect?

450nm (royal blue), UV is <400nm.

Thanks. Is this valid for all white LEDs (with phosphor removed)? I could make royal blue LEDs by myself then (I ordered royal blue for my D4 RGBW, but they didn’t show up yet). Protection glasses not required, I guess?

Are LED4POWER’s custom MCPCBs so far all there is for a good fit with these Luxeon V’s?

My understanding is that most white emitters use a Royal Blue emitter (not sure of peak frequency at the moment). There was an LED that was to center around 410nm by SORAA LED. I don't know if it ever came out. Here was a thread on it:

Did you see my question in Post 127 above?

Imagine Emisar D7 with 21700 Samsung 30T, copper sandblasted head, anodized aluminium sandblasted body, copper dtp board for 7 Luxeon V emitters together with Ledil ANNA 7up spot optics! :innocent:

Is D7 released light? I will probably make a new batch of mosX boards next month, I already have few boards that I'd like to make,if there is enough interest I can add few other designs.

D7 is not yet released but as far as I know it should use 3x18650 and 7 emitters I suppose judging by name. I would love to see 21700 design though! In my opinion Emisar series should be single cell lights and Noctigon series multiple cell. I hope we will find out soon what D7 will look like!

I would love to see 7 luxeon V mosx boards compatible with Ledil ANNA! It’s the way to go. I am very optimistic in believing that in 2018th we will se more 20700 and 21700 single cell flashlights.

Btw I’ve built S2+ triple luxeon V with your parts led4power. I saw 16.2A with my Uni-T UT58E with extra thick 3.6mm short speaker wires and vtc5a. Output is insane.
Should be 5500 led lumens being on a conservative side. If 20% is lost (I am not using lens in front if optic and I I grinded lip to have optic and exposed as much as possible) I should be getting 4400 lumens OTF :partying_face:

Sorry, missed that question. Apart from what I wrote earlier, I couldn’t detect anything unusual.

It looks like the Lux V boards are out of stock. Any ETA?

~1week (new 16mm and 20mm).

Thx!

Whats its the recomended center gasket for this led in a convoy s2+ (7mm opening reflector)?

I forgot to update status in this thread; DTP PCBs are available now:

You will have to adjust one, I reamed a XP gasket with one of these:

I’m still waiting for my order from led4power. Hoping it’ll get here soon to see what the hype’s about. LOL

I just came from outside. Had a bit of fun :innocent:

Cool pic! :sunglasses:
