3 volt XHP50.2

mine too:))) we are two already.they have to start producing it:)))

How’s the rainbow with the lower CCTs? I find the 3V 6500K XHP50.2 unbearable honestly. When I compare it to the Olight R50 XHP50 (6 or 12V, dunno) it is as if those two LEDs are from different worlds. There’s no rainbow with the Olight, just an evenly distributed (green ) beam.

Hm.thats frustrating veery for me.isnt there any similar emmiter for 4leds/1 lion home made hot rod?

SBT90.2 . The LED itself is rather expensive but output is very high, efficiency the same as XHP50.2 despite no dome. Maximum output is higher.

djozz said that the CT on his sample is neutral , but I don’t know which bin is on Convoy store.

VrestoTaylor · 2021-03-17T11:05:51.000Z

uff…thats too expensive for me…btw four xhps are more than enough:))) but who is listennig to cool white leds in 2021?? me not:) i want neutral so thats really shame its out of production…

I doubt the cct will drop that much by slicing. I sliced a 6volt 50.2 and saw only a small drop.

pennzy · 2021-03-18T20:47:23.000Z

Maybe I’m estimating wrong. I’m just going by eye. It did improve the cct.

Agreed. I had them in my cart for weeks and just couldn’t bring myself to do it. They are available though.

Let’s be real. How much would be shipping from Australia to Finland with just a regular envelope or something like that? Any Australians that could help me out here?

A$3.70 for an economy air letter, or $17.70 for a registered letter. 25+ days delivery, no tracking, and technically only printed material allowed.

A$29.40 for a small parcel up to 500g. 9-15 days delivery with tracking.

Skylight:

The lowest tint I know of is 1D which is around 6000-6300K.

What happens if you slice that? Lower tint, maybe? And a bit more throw like with every sliced led?

I have one sliced. See gallery here

For those interested in 5000K it appears Sofirn is selling it.

I ordered 4. Will have to wait and see what actually arrives.

If anyone has any reservations from ordering from Cutter because they’re in Australia, I can attest that there is no reason to worry. Recently put an order in for some 3B0 (5400K) 3v XHP 50.2’s from Cutter. Had a small problem and Mark stepped in to quickly correct it for me. VERY reasonable shipping to the US, I would definitely buy again.

Otherwise, these 3V emitters are great, just wish we could find them in 4000K!

How did you find your 3B0 (5400K) LEDs from cutters did you also get that yellow green shift in lower settings like KawiBoy1428 did?

thx

They are what they are, I very much prefer high CRI emitters in the 4000K range, so these definitely have some coloration that isn’t ideal, both in lower settings, and with the reflector I’m using (stock OP S2+), the spill is very blue/purple. I suspect using a reflector or optic that’s designed more for a emitter the size of a XHP50.2 would perform better however.

With that said, these things are screamers. If you just want an obscene amount of lumens, one of these paired with a FET driver and a high current cell is a really easy way to get a lot of output.

From Sofirn? Were they in stock when you ordered? Shows zero now. Only stock ones are 6500K.

Once again the Cutter listing is sketchy. If you order them, it shows in the cart: "3B0" and 5400K. I can't find "3B0" in the datasheet, only 3B, and 3B is listed as 5000K. I don't think I've ever seen a LED from Cutter consistently, correctly listed -- ever, and I've placed a few orders over the years. However I must say I've always gotten what I thought I'd get -- it's maddening to say the least.

I would absolutely not trust Sofirn for ordering LED's - when the 5000K's were actually shown in stock and I ordered them, instead I received 5700K's. Others reported the same thing. Definite not a trustworthy source for LED's.

They’re out of stock at Sofirn since a really long time. Had some on order last year but cancelled a few months later.

So, good luck.

welight · 2021-04-30T00:49:07.000Z

Kinda interested in whats inconsistent with the description. 3B or 3B0 is the same thing, 3B0 is typically how its labelled in the part number.
Is it 5400k, well we list it based on its outer extreme, yes it falls into the 5k bin description but it could be at worst around 5400k, we would have to spectral test to give an absolute

Please if you have a better way to list parts im all ears
Cheers

Tom_E · 2021-04-30T03:08:00.000Z

Just consistency. If it's 3B0 in the part # and it's the same as 3B, that's great. Just that on this page, it says "3B is 5000K", but in the drop down selection, it says 3B0 (5400K) and no choice of 3B (5000K). Now that you explained it that it's the same, that's good to know. I know you always have, and send the right thing - I always get what I expected, or better than expected which is why you are one of the rare trustworthy sites around, but I know International shipping is not cheap.

Boy, I got qty 10 in my cart which comes to $7 each shipped to US, which isn't bad at all. Wish shipping was cheaper, but I know - we whine about it and are spoiled rotten with Chinese retail sourcing.
