If he is out I still have some that I ended up not using I could sell.

Which batch are yours from?

I have not kept up with them, I am not sure how many batches there were. I think they are from the 2nd batch? But it might be 3rd?

If you search this thread you should be able to see when I ordered them.

The first batch I really liked but not sure I want to take a chance on another bin I haven’t seen. I’ll prob wait a bit longer to source more

Same thing.

The first batch was a tint binned T6, so a chance to get a below BBL LED, and a slightly above BBL LED.

Looks like the model I got was the the F2T6Q2 bin. No idea which batch that was from.

1st batch I'd say, 2nd batch was F2T7Q2 if I do recall correctly.

Thanks Texas_Ace, PM sent.

Thanks, I order so many LED’s for testing in hopes of finding that perfect LED I can’t keep track of exactly what I have. I just know I have a shoebox sized box full of LED’s I will never be able to use lol.

And then, of course, when you do find The Perfect LED, you won’t know which one it is.

lol, yeah that is a valid concern.

If they are still available, I’m interested in 4 pieces of the 351D, 4000K (F2T7R2).

As long as I’m ordering, I might as well take also take 2 of each of the available bins of the 351B, 3000K.

Thanks!

I’d like to order a few:

1)351D 5000K 90cri tint F2R1S2 300pcs 1.7$ – 10
2)351D 4000K 90cri tint F2T7R2 20pcs 1.7$ – 10
3)351B 3000K 90cri tint D2V7H1 60pcs 0.55$ – 10

Привет андрей,

Do you have any plans to sell other LEDs apart from Samsung LH351B / LH351D? I know it's always dependent on the actual interest here on BLF versus the MOQ of 800 LEDs. Just being curious... BTW: I still like the thought of getting some LH351D 3000K 90CRI or LH351D 4000K 70CRI (for comparable output to the 351D 5000K 70CRI W6 flux bin).

Cheers,

Томас

Thanks Andrey, I will have a look into that, too. Currently, I'm looking for a reliable source to buy XP-E2 photo red (650-670nm) and XP-E2 far red (720-740nm) but I'm unsuccessful to find a seller.

Anyway, all your LEDs have arrived in perfect condition and work like a charm. I'm very satisfied both with the 70CRI (for maximum performance) and the 90CRI (for best colour rendition). It seems the quality of 90CRI light will be significantly influenced wether you use an optic or a reflector and - to my surprise - if you use an AR coated lens or one without coating. The best color rendition seems to be gained by using a mule design (e.g. Solarforce P60 quad LED board) without AR coated lens.

@Lux Perpertua, are you sure you want to get LH351Ds from Digikey?

If so, then I can help you out.

Thanks for the kind offer BlueSwordM! Actually, I was interested into a bunch of LH351D 3000K 90CRI for comparison to 4000K and 5000K 90CRI or for a triple independent light (KD dropin) with all three tints in one light. But I'm not sure if it's worth the high shipping cost from Canada to Germany...just thinking. Maybe it's worth taking a closer look to Arrow, Mouser, Digikey and so on. Mouser has a lot of LEDs but they charge "pharmacy prices" for shipping over here. It's hard to find a source where you can rely on purchasing the right flux bin / tint bin, though.

Shipping will not be expensive via the method I’ve used before for shipping, and I haven’t had any problems with them with my special kind of envelopes.

Shouldn’t cost more than 5$US to ship via that method.

Will have to order at least 60-65 emitters to get free shipping too however.

Arrow has top flux bin red XP-E2s, bought one in the past. Some others in stock, too.

Paypal sent! I hope my slow response was no trouble.

I’m looking forward to putting one of these in an S2+ to compare to another S2+ that has a 219C in it. Also, I will probably try slicing one like Djozz has discussed to see if I like that better.

Thank you Andrey and Barkuti!

I checked all known sources for XP-E2 photo red and far red but I was unsuccessful with E-Neon, Mouser, Digikey and Arrow. The one and only source I could find was cutter.au which is an Australian supplier and I have no idea how reliable it is and how much shipping would be just for some LEDs. The Samsung LH351H (deep red) is very much like XP-E2 red, i.e. 1A maximum current, probably peak at around 1.75A max.. Anyway, thanks for you help.

Has anyone tested the LH351C yet in comparison to 351B and 351D?

Cheers

Thomas
