More New Cree Goodness coming....

I put a XHP50.3 HD 4000K 90CRI from Digikey into my Skilhunt H300. My Opple says its a bit green, but thankfully my color-deficient eyes canā€™t tell :disappointed:

Gchart, that pic looks like a gen2, no? I thought dot three versions had a white silicone pour around the die.

Good eye. That picture was taken before the emitter swap. It was more of a ā€œhurray, I got it openā€¦ and hereā€™s what it looks likeā€ picture. I have updated my post to note this.

The new LED does have the white around the die and is not covered in a phosphor pour.

XHP70.3 HI looks interesting.

XHP70.3 HIs have been listed at Mouser, several of them have a MOQ of 1 (none 90CRI :frowning: ), no lead time info.

The XHP70.3 Hi looks like perfect LED for ZL SC700d :sunglasses:

I didnā€™t test higher because itā€™s a quick test without heatsink, anyway the tint is sunlike (0.0033), or slightly greener at lower current. Disappointing that itā€™s not closer to the BBL

The beam looks quite good even with SMO reflectors.

At 0.1A with KR1 SMO reflector :
spot : CCT = 4605K (Duv 0.0033)
Corona : CCT = 4191K (Duv 0.0067)
spill : CCT = 4383K (Duv 0.0032)

1 Thank

:+1: for the data thefreeman. Cree is not the new Nichia but it looks decent, 90CRI Creeā€™s that I have seen before were awfully green (that was before I had a spectrometer, so I can not back that up with duv numbers), this sounds better.

Added a quick spot, corona, spill measurement with SMO reflector

A bunch of them got added in order, availability announced for March.

Cutter has some stock of 3V XHP50.3 in 3B chromaticity.

The 4000K 80+ CRI looks interesting. But man, $12 a pop

I have these underway, any interest

For those who love warm XHP50.3 HI 3000K, XHP70.3 4000K 90CRI
available here

Too bad we donā€™t know what the tint is like. If we know for sure it has rosy good tint, I would buy.

Have you ordered from this site before? They mention shipping to Russia & Ukraine, do you know if they ship to EU/UK?

Do I try a 70.3 in my FET L6?

Maybe Iā€™m not so good at reflowing, but these XHP50.3 HI 4500K 90CRI LEDs seem to be rather fragile when it comes to current. I went just above the limit on two of them at 12V and they burned out rather quickly. My heat sinking was probably not adequate either but for now I Iā€™ll give up on these until someone who knows what they are doing does a more thorough test.

I got a 6v XHP50.3 HI doing 4k lumens I think the current draw is like 8-9 amps itā€™s okay but Iā€™ve only used it for testing. I tried to reflow one and the dome melted.

Must be my crappy reflowingā€¦ I should stop buying bare LEDs and only get mounted to MCPCBs by people who know what they are doing.

I re-configured my driver for 6V and put in a MT-G2 instead, those things take a lot of abuse.
