Also in 5700K 90CRI and 3500K 80CRI


Wow. That 3500K is a dream come true. Great CCT. I like CRI 80. It’s even 1 bin group above what datasheet offers at this CRI/CCT.

I looked closer at that. There are many contradictions and unknowns in the listing:
  • picture and title say CRI80, description says CRI90
  • title says T6 F4. T6 colour bin is 4000k not 3000k. But T6 is also a flux bin group – and higher than what Samsung lists.

So…BanL, it would be very useful if you clarified what bin is that.

OKay

I will re-organize the product title.

I see that there was an update – the Samsung product code is SPHWHTL3DA0EF4U0T6.
This means:

  • 3500K
  • 80CRI
  • T6 flux bin group
    • one higher than Samsung lists for this tint/CRI
    • this is not an exact bin, this group consists of T2, U2 and V2 bins which go from 400 to 460 lm
  • ANSI binning” – this basically means that tint can be in any of 16 bins. May be very rosy but may be very green
  • F4 voltage – again this just means “any voltage”.

Note that this is a code used for ordering rather than exact binning.
The reel should have the exact bins for voltage, output and tint specified.

So – thank you BanL for this information. It is really useful. But if you managed to get the exact binning from the reel it would be even better. Smile

ADDED:
The 5000K CRI90 variant is SPHWHTL3DA0GF4RTS6:

  • 5000K
  • 90CRI
  • S6 flux bin group
    • the highest for this CRI/CCT that Samsung lists
    • this is not an exact bin, this group consists of S2, T2 and U2 bins which go from 380 to 440 lm
  • ANSI binning” – this basically means that tint can be in any of 4 bins. May be very rosy but may be very green
  • F4 voltage – again this just means “any voltage”.

I think adding a photo of the reel label will be the best solution.

Hey, i just received an order here, and this includes a quad SST-20 with optics.

I’m pleasantly surprised to see that it fits just fine, as long as you stick the feet of the optic in the slightly narrower slots.

The slightly wider slots are for the screws.

…but the narrower slots are still too wide… Sad

You’ll have to secure the feet in the slots with a drop of Kafuter UV curing glue (or something similar, as long as it hardens / doesn’t stay flexible) before screwing on the bezel / screwing in the pill (depending on the light).

It’s very subtle but check and make sure the optic is not resting on the LED substrate. It’s hard to see any problem but once you crank down a bezel it could cause issues at that point.

Dang, it seems i spoke too soon, again (bad habit…)

You’re right, the optics do rest on the emitters AND the slots are still too wide…

Only 1 of the legs does not sink too far in the slot…

Thanks for the warning. Thumbs Up

Here are some fotos and beamshots to give you an idea of what a 90CRI XHP70.2 5000K looks like. It is not the one sold by Kaidomain but a XHP70.2 N2 3A (according to the seller) from Taobao.

In the MantaRay C8.2

Outdoor beamshots at night. The trees are 100-150m away. White balance has been set to 5000K. Sorry for the bright street lamps.

For reference the Convoy L6 XHP70.2 4000K. Note that the XHP70.2 90CRI looks more like daylight while the 70CRI is more yellow/green.

This are three different XHP70.2 to compare the yellow color of the phosphor on the led. From left to right: 5000K 70CRI, 5000K 90CRI, 4000K 70CRI

Thanks for posting that but I honest couldn’t see the difference between the 70CRI and 90CRI in the two pics. Also the flashlights seems to be aimed at different angles, which makes comparison difficult. How does the tint compare? Is one more yellow/green than the other on a white wall?

I will take some white wall beamshots as well. The L6 with 4000K 70CRI is more visible than the 90CRI because it is throwier, has a slightly higher current and the 70CRI is generally a bit brighter. Maybe somewhere in a dark natural landscape it would be better to take beamshots of high cri flashlights.

I tested tint of the new batch of KD’s 2700K SST-20 leds, claimed JA3, that came in today.

Kaidomain’s previous batch was JC1, which should have been just above the BBL, I tested the tint here: http://budgetlightforum.com/comment/1465746#comment-1465746 , and, at ~400mA, from above and at 60 degrees the tint was under the BBL, just in the hotspot from a OP reflector it came very slightly above the BBL.

This evening I did the same tint test on the new claimed JA3, which should be under the BBL, and all three tints: straight above the led, at 60 degrees and in the hotspot of an OP reflector, measured almost exactly as the previous batch of claimed JC1 bin.

Also visually I can not tell the “JA3” led tint apart from the “JC1” tint.

This is an extremely nice led if you like 2700K light, nothing bad about that, but this is not good for trusting tint bins that are offered by Kaidomain, no matter where the problem is, at KD or at Luminus. Apparently everything must be checked, which costs money and time.

I bought 7 of these, if I had known that they were the same as the previous batch I would not have bought them, as I still have a few of the previous batch leftover.

I finally got round to testing these! I bought a batch when they were first available and another a coulple months later. There’s a very noticeable difference and would say the first batch, although sold as JA3, were in fact JC1. The second batch have a noticeably lower DUV, similar to the first batch with an 805 minus green filter.

I also had a go at slicing these (just above the bond wires). I didn’t notice any dramatic changes to output/throw but the tint gets rosier and the hotspot smaller. Only tested in OP reflectors so far but haven’t noticed the starburst effect I’ve seen mentioned. Overall a very nice improvement.

hodor, that’s good news. When did you buy the JA3? According to your experience, it seems like KD sent Djozz the JC1 instead of the JA3.

Hopefully BanL will resend the correct JA3 emitters to Djozz for free Wink

Also the 2700K JA3 from Fireflies is a bit rosier than the 3000K HD2 bin from KD. The 3000K HD2 from KD was tested by Djozz to be rosier than the KD 2700K JC1 bin.

Yep, I guess he got rid of the last bit of the old batch with the new batch already listed.

Quick question fellows, did someone tested any of the Osram KW led emitters @ Kaidomain?

Yea i bought both and have used them in different lights. I think a output was done on both of these.

General KD question fellows, does anyone knows what is the relationship between Kaidomain and the LHT Flashlight store?

Not the same products in the latter, and prices are jacked up.

The LHT Flashlight store is owned by Kaidomain. They have more products listed on Kaidomain’s own website.

I suppose the prices are higher because of the Aliexpress fees for the store or just because they can make more profit on Aliexpress. Wink

Interesting! I thought they were $16.50AUD each but looks like that’s for two.

Hhhhhhmmmm….

4A or 4D would be nicer though Wink

Anyone got any LH351D’s from KD yet? Curious to know if they’re as advertised. Saying that, we still don’t know the tint bin.

Got some LH351D 5700K. Can’t test them properly but I think the colour is slightly above BBL. And I wasn’t amazed by the colour rendition.
I have some Nichia 219b -V1 5700K and I consider them to be nicer.

I tried the 5700K in a Armytek Prime C1 Pro with a Yajiamei 15° beaded optic and I would also say it’s slightly above the BBL. The lumen output is quite impressive though.

I’m waiting for my headlamp to arrive then I’ll try it. Then I can do a direct comparison to 5000K that AEDe supplied.
