budget yuji high cri 5mm leds confirmed

well i now know what these are.
look at sellers other auctions.looks like they build photographic lights with these.
i installed 2000 of these in custom light strips in a friends home.not a single dud and very consistent in tint and brightness.
a quality product.what a nice surprise.
a huge upgrade from the early 5mm the strips were built with.

Exactly what I was looking for.
I have those cheap camera-lights with the nice tint in my wish-list since months - but I want the bare LEDs. only for custom projects.
500 for 8.79 - I guess I need 500 more LEDs :wink:

Interesting that they can be DD’d like that. Have to try it and measure Vf at that current. Must have a steep curve.

I did put a set in my favorite magnified visor. Nice smooth beam pattern and I agree tint is around 4500. CRI is decent. Not sure I would call it high CRI, but I’m not a good judge of that. Definitely, better CRI than any other 5mm I have ever used. Output was down a bit from the stock cold tinted LED’s in my favorite visor, but still quite usable. Expected that. I guess I’ll pull the resistors and let the 3S2P AAA’s drive these emitters direct. I’m using Ni-Mh’s, so voltage should be similar to a typical 18650.

Thanks for the alert. Heck of a deal and the price has dropped to under $7/500.

yes these seem to have a higher vf.they even do good in a super cheap dollar tree 3 led dd.
the - leads fold over the board edge giving a path to the thin tube.dd with a cheap 18500 gives output like many older luxeon lights at less current.
all in a package thats disposable/loanable.
as for cri its hard to determine that without proper test equipment.and eyeballs are too different.

Ebay store from OP can’t accept payment, so I have messaged seller and he sent me paypal invoice directly to email. Not exactly by ebay’s book, but I don’t have any doubts since invoice was for service, covered by paypal protection. Now the waiting starts, I just hope these can replace horrible blue led in Nitecore Tube.

btw these have a wider beam than most cheapies.spot intensity is lower but more light at the same current.
an unmodified hf freebie puts a tight blue spot on my white ceiling.same light with these at same current wash it out.floods a dark room nicely.
even better if you spray the 9 hole reflector and empty board white before you assemble it.real nice disposable work light.rolled up cereal box cardboard as a spacer takes an 18500.and still allows use of a 3aaa holder.

This item is no longer available :frowning:
If someone finds a similar deal please post a link!

keep that email handy.looks like they closed the ebay store.
if you dont mind send me the email via pm.

Dang, I missed out on these.

A quick goodle search of the part number JNL5254CHLGW5007-CA4 brings up a different ebay seller, and also an ali store that uses the same images as the store in the OP.

Good catch.will look again once I am not on a phone.
Even the note is awkward doing some things.

I hear ya, that’s why I didn’t post links. Ali links always seem to break when I post them from my phone.

How do you know it’s hi cri led?

The original seller claims ra75.
They have greatly improved color rendering over any other 5mm I have used.and they lack that cold blueish tint.
These were for high end photographic lights.

I built myself some little Modules for photography - they are extremely good.
I would say, the CRI is easily over 90 and they are perfect for lighting stuff for photos or in glass cabinets

Only link I could find to that part number was : http://www.ebay.com/itm/100Pcs-F5-5MM-White-Color-White-Light-Round-Superbrigh-t-LED-Lamp-/181935336943?hash=item2a5c30edef:g:UCoAAOSwnGJWTDrq

Anyone know if these are the right thing? How do we know they are in fact high CRI, I didn’t see it mentioned in either the old ad or this one?

I would not mind having some neutral/warm white high CRI 5mm LED’s around. I figure I can rebuild some of the many 9 LED lights I have laying around if nothing else.

if the part number shown in the listing is what they ship then yes they are the part i posted.
might want to ask seller if this is the case.
the bag shown is not what i bought.

My anti-static bag has a similar looking label, but says “LED LAMPS” at the top and has the information that is in the Description section of that Ebay ad. So as snakebite says, if the description is accurate, those are the LED’s you want. If the picture is accurate, those are not the LED’s in the OP.

Just checked the ali site on PC that I mentioned earlier, the seller was Power Magic but they no longer have any items for sale.

Both links in the original post go to pages for items no longer offered for sale on eBay

search for JNL5254CHLGW5007-CA4
other sellers have them.
