Would anyone be interested in Samsung LH351C 5000K 70CRI LED at price of 0.7€/pc?

Manufacturer number is SPHWHTL3D50CE4RTQF, flux bin is highest QF bin(310-370lm @700mA,Tj=85C).

This LED is interesting not just because of low price, but because die size is smaller than 4mm2 LEDs like XP-L,LH351D etc. which means narrower beam when used with 3x,4x optics, while lumen output looks fairly impressive, at least up to "stock maximum" of 2A.

I guess a test would be handy….

I’m a high CRI fan so a 80 or 90CRI version of the LH351C would interest me more, but it is nice if we have a convenient source for the LH351C which has good specifications! That said, I would like to see it tested and perform well in practice to become really interested.

I think the manta ray c8.2 host that uses a 26650 cell will work nicely for the ANNA 7x optics. The head size is the same as a convoy c8 and it might be easier to make a spacer for the manta ray than the convoy. It will definitely improve run times with a 26650 cell over a 18650, but probably not as popular.

I’m sorry if this has ever asked before, how does the mode/UI of the LD-x4 works? Any diagram or mode list would be helpful. Thanks.

LD-x4 datasheet v1.1

I received this led from you today thanks.

Is there anywhere I can safely drill two holes in the MCPCB (probably the wrong term here :slight_smile: ) to screw this to the pill? The pill itself is only about 17mm in diameter in the driver area. The pill itself is a modified B158 item.

Bacuse most of surface is covered with copper top layer (it's visible in pictures),drilling holes is too risky. Even sanding it down to 17mm is problematic,but in theory it can be done, dielectric layer is very thin,so risk of short is bigger.

Thanks for the response led4power. Plan bit is then.

any word on new products? new mcpcbs and stuff?

From when can you buy the Luxeon V again without mcpcb ?

New stuff just came today:

16mm 3535 (XP) Cu DTP

20mm 5050 (XM) Cu DTP

20mm triple 3XP Cu DTP

20mm quad 4XP Cu DTP

All Cu DTP boards have 1.5mm thickness,70um copper layer,gold plated top surface,nickel plated bottom surface and pads for 0402 NTC thermistor as temp. sensor.

31.4mm mosX 3x 3535 and 3x 4040 for CUTE-3

31.4mm mosX 4x 3535 and 4x 4040 for CUTE-4

31.4mm mosX 4x 3535 and 4x 4040 for ANGIE

34mm mosX 6x 3535 and 6x 4040 for ANNA

31.4mm mosX boards are compatible to Eagle Eye X6 and fit without PCB drilling and sanding (except small edges from V-cut). Spacer is required of course.

34mm mosX boards are designed for use in Convoy C8 host with 6x or 7x ANNA optics (in case of 7x ANNA central tir is not used). Spacer is required of course.

First fit-test pictures:

I assumed no one would want bare Luxeons after I got PCBs,because I'm the only one who has 4040 DTP boards in stock.

Anyway, just relisted bare Luxeon V again.

I will put some pcbs in my store tomorrow,

prices for Cu DTP boards will be:

16mm (single led) - 1,07€/pc

20mm (single led) - 1,17€/pc

20mm 3XP,4XP - 1,37€/pc

Please contact me over store contact form or here on PM for higher quantity discounts.

Where to get them?

I will have them soon, also whole DIY kits for EE X6 and Convoy C8 with Luxeon V and Samsung 351D and different power levels.

Will the 6x MCPCB fit Convoy BD01, BD06 or other 26650 Flashlight?
Or do you know an 3x 18650 Flashlight for it?

Edit: perhaps:

@Wieselflinkpro

When the 21700 C8F comes out I plan to start a campaign for kiriba-ru to make exactly this spacer

Wow, those are looking good. FYI, the Manta Ray C8.2 also has the same size head as a C8 and will fit the 7 anna. I highly recommend this host, since it’s powered by a 26650 which will improve run times for so much light. I made a custom spacer for a quad here: What did you mod today? - #5538 by vinte77 .

Any update on the ETA for the MZ emitters?
