New red diodes from cree

What is the cost per reel?

Findings from this year’s “State of the Cannabis Lighting Market” report echo those insights. When asked what factor was most important to them in opting for LEDs, 42% of study participants cited “crop quality.” Plus, nearly half of respondents reported average yields of 80 grams per square foot or more (up 33 percentage points from 2023). And this year, a new question on spectral properties and purchasing decisions was added to the study. (Nearly a quarter (23%) of respondents said “40-50% red” was the spectral property most important to them.)

You know it's gonna be high $ af, they haven't got a price or datasheet out yet, but looks like it'll have a higher current rating 700ma with a 6% efficiency boost over xpg3 s line. I think this is cree response to osram osconic hyper red. Which I have been looking into as well. I'd like to see more efficient 630 NM and far red diodes come out as well. They had a new bins come out for xpg3 and xpg4 s line whites which put em at 220 lm/watt. High powered diodes are catching up in efficiency. With Samsung jumping out the game I'd bet we will see some interesting new products.

Osrams 640nm is pretty damn efficient its just that 660 will always have an advantage in ppf/w. In radiant output theyre pretty much the same as long as you can manage to get top bins.

I'd really like to use some of them osram osconic reds, still ain't found a good cheap mcpcb, this would be time to break out the supply's and figure it out. If I'm going that route I'd like heatsink and circuit board all 1 piece, think I'm gonna try it.

They look really good but as they become more available check pricing on second best diodes, oslon. Many times you see sharp price dropp in runner ups when something new and shiny arrives, just as thosexpg reds you (or someone) posted recently. Checked the datasheet the oslon 640 is good enough for me even in mid bin to be employed. 4000k with wide redsup is looking better and better to me.

Yep, the cree xpg line is pricey. Exactly right about HP-white efficiency, I've been saying that for a while now... HP diodes allow for feasible optics as well. They use them in commercial lighting as a green filler between mono red and blue for a more balanced spectrum. Personally, I'd like to see that happening in the grow tent space as well, but that means going back to blurple or pink light. It's a lot more efficient because and imo when dialled in properly- it's just overall better. It requires more skill from the grower to not bleach tips and burn and you can hang the lights higher which in turn spreads the light better. Would be nice to just put in a single bar which covers the whole 4x4 space sufficiently.

Not sure where your pricing. Sounds like catalog distributor issues(digi, mouser), not really Cree.
Any real company doing business in the LED industry will tell you most similar companies will match others. i.e. Cree and Osram are same same for production pricing. Especially direct, but even through distribution(WPG, Arrow, Avnet).
Doesn't mean Cree, Osram, or Nichia will play in the seoul pricing game or a LM80 less china supplier... but they will go after each other on even pricing fields.

So DIY, your left to what the categlog guys markup. But for all the companies out thier having to change from Samsung...Cree is highly competitive, high power and midpower.

Yup but that's one of those good deals that won't last long they are s line lower f bin, well worth $0.50. These are the ones I bought


They also have xpg3 photo red s line g bin1 bin better for $2.04 each I won't pay that much anymore,

Ya like I said, retail problems.
Reels of xpg's are 1000pcs. One reel is tidily winks for a business.
Those links are no different than buying from Digikey.

Getting a glimpse in that first link for sub .50. But still...you're not dealing in real business level for these LED companies.
The second link at 2$...the standard book cost is under a dollar. No company buying from Cree is buying at book cost. All have designated pricing for their businesses.
And that's not just cree...its how the whole industry works from near every manufacturer.

So need to separate one's individuals DIY needs and the extreme markup that retail level pricing brings from the actual industry and what they should be implementing to have the best performing and value products.

Do you know anything re cree 630-640nm? Do they have any good options?

Crees plain red is 620-630nm(XPE2). Then photo reds at 650-670nm(xpg3 or this XPL when available).
The most under the radar from cree is their 730 xpe2's. Worthy of using even if using other brands for white or photo reds.

Adding to this on standard 620-630nm reds...

Their 628nm dominant red(upper end bins)
Conversion Factors Being Used:
LER (mW/lm)154.0
PPF/flux0.034400
Their 625nm dominant reds(more standard bins)


Conversion Factors Being Used:
LER (mW/lm)176.0
PPF/flux0.030300
This shows crees data converted to µmols with these figures above...

Screenshot 2024-12-16 at 8.47.03 AM.png\

628nm bin is pretty good at holding above 3µmols/j. Figure as long as its more effient than the white being used, and its giving someone the spectral quality they need/want, it's not a bad choice.
Though a 640nm like osram would have even more of a µmols advantage. Even getting up to just 635nm would make a difference.

Anyways, that's the data...take it for what it's worth.

Cree's monos are too expensive and they will have to come down significantly in price to be feasible in consumer grow-lighting.

I'll say it here too. They are not expensive to the industry. Digikey, mouser, and Arrow are expensive to you. You buying a couple reels over the counter at distis that make 50-75% margin from guys off the street...is zero representation of what the "LED Industry" will do to make the best products. If you think any growlight company buying from cree will pay more than $0.50usd for a 660nm your crazy. Let that sink in compared to what your paying over the counter.

Let's talk data, cause that doesn't change no matter what distributor is ripping you off.

Well yeah, obviously mentioned are ripoffs.

However, historically Osram has offered a much better value proposition.
