A Samsung 3535 -LED in SKY RAY 701-"R5"

LED Flashlights – General Info

Ok, here´s the deal:

Purchased a while ago this:

http://www.cnqualitygoods.com/goods.php?id=1410

Arrived today. Works.

First impression is, that beam slightly bluish, a bit too much bluish for casual R5.

Not sure if it´s a fake but definitely sure have not seen this kinda R5 ever.

Notice different kind of LED PCB. Emitter itself also seems a bit awkward.

Then looky here.

Can´t see any of those familiar XP-G segments in emitter there.

More likely there´s "some dots" in a pattern.

Notice, that this is probably the only reflector type, that "allows" you to hide most of the LED emitter, only showing the die.

Many would notice this kind of difference straight away, since it is just a bigger difference in SMD components color for example.

Looking the difference from the die itself needs a better look.

For reference:

You given Ric a heads-up on this one? Since I generally have faith in him, I'd guess his supplier is screwing around.

That looks like a Samsung 3535 LED: http://www.led1.de/shop/images/thumbnail/produkte/big/Produktbilder/SPHWHTL3D.jpg

Looks a lot like the new Samsung LEDs, which some have discussed around here that they could match the CREE XP-G R5. We know who everything is read from BLF.

Definitely it's not a CREE XP-G R5, neither is any CREE LED, it's the Samsung 3535 LED.

Bingo! Thats the one, it was too hard for my cam to pick up those textures in LED die but with bare eye & good sight, that´s exactly the case.

Thanks!

I have just quickly taken a look to it and now I´m going to take a nap but

lumenswise it seems to be around 70-90lumens possibly, hard to say anything exact until I compare.

Current draw is ~1.35A on High.

7

That is interesting, as I always wanted to try the warm white version of that emitter. (They have a higher CRI than the according CREEs) How is the beam pattern compared to your XP-G lights?

8

Well, I got only too good references...

It has a spottier beam than my C3 SS modded to take R5.

It has about 1:1 spot size compared to my SC51w but it has around 15% wider spill area, not bad I say.

Interesting, the above mentioned C3 SS has original driver. It takes on a fresh Eneloop around 2.25A and this manages with ~1.36A BUT puts out very closely the same and with slightly depleted Eneloop, more than C3.

Compared to Zebra (harder to me compare warm & cool, take with salt) this manages to put out very closely to what Zebra has to give on H2 (86lm).

Just a note: Zebra takes at that level about 1.8A and this only 1.35A.

How come this seems to be not-at-all bad efficiency-wise?! A light under 20$??

After all, that Samsung should IMO be quite close to R5 or not?

9

It is advertised as a direct XP-G replacement by Samsung, but some people say that the tech-data that Samsung publishes is a bit optimistic. But it seems to be within 5-10% variation to the according Cree... so barely noticable difference in output with human eyes and about the same efficiency class. (scroll to the end)

10

This should be interesting to compare with those earlier 701-R5´s which seemed to have a real R5.

Don at least has one, pics show the LED.

I cannot say this is better or on par with R5 because all my lights have different drivers etc. but I can say I´m just a bit surprised of it´s output vs. current take vs. price.

11

Very interesting, as mine was 100% shipped with a Cree....sounds like a running production change.

12

Mine is XP-G too.

13

BTW mine has thermal paste under the plate.

I have been running it continuous this evening, seems to work.

Tint is IMO cooler than in a cool R5.

Hmm, answer from CNQualitygoods:

Dear Mr. J

Sorry, The link https://budgetlightforum.com/t/-/7578#comment-148795 you offered can not login in.
The CREE R5 LED we only have one type.
Best regards
Merry



Hmm, Ok........
I mailed direct links with pics to them.

15

Better directly contact Ric... language barrier as huge as the Chinese (fire-)wall ... it seems.

16

Just wrote a pm...

17

Hehe...

Got another response from customercare: "We don´t sell that led, only R5 etc..."

:D

18

I don't have that Sky Ray.

I do have two of the Uniquefire version. One is dead - it really couldn't take 14500s... The second one works just fine and both are genuine R5's I've just had a close look at them. If anyone knows of a driver that would work in there given the electronic switch, I'd like to know. The LED in the dead one still works...

19

Are you able to get a clearer picture of that Samsung LED? They're not too common and I'd like to add a picture to the flashlight wiki.

Sorry :(

It was a bit tricky to zoom close enough with macro on my Canon P.O.S. when LED was intact.

I could take it apart and photo but it was ordered to my friend and I already gave it away, too bad...
