Semiled has pretty good UV and near UV diodes. They are often used in aquarium lights for instance.
Rapidled has different wavelength available like these 390-400nm ones.

https://www.rapidled.com/semileds-ultra-violet-uva-led-390-400nm/#tab_specs

I've used 425nm Semileds(950mW @Test current, 3,6v) and will use them again combined with XP-E2 blue (group B5 480nm, M2 bin, I've not found M3, B6) to supplement my 2700°k HL boards. The additional mono string will have 4x 425nm, 4x 480nm, 2x 660nm (Square series) and 4x 670nm (XP-E2's), dimmable, max. 600mA, ~25w at the wall and supplements 2 boards at 100w each. I should may wait until june, lol! XP-G3 in deep-red. Damned, can they also handle 2amps?

The 2700°k/CRI95 HL spectrum has already enough far-red but I want a wider blue range, a filled cyan hole and some additional deepred. Goal is to further reduce the difference the spectrum has against the mc cree curve. I also have a 24w T5 reptile bulb so in the end each fixture will have around 250w. I still wait for some parts but not to long and I can start assembling.

Where did you purchase the semileds from? Was there customs taxes to pay
There's not much choice in these parts. Just 3w and 10 watt epileds
10 watt 420nm epiled costs £6.59
2ft vesta strip costs £7.00
A bit more flavour verses even more buds lol

Think they will be a better proposition than H_Influx? I'm looking at building a 6 or 8 beam Hinflux S03 and L06, the high-density single row versions.

if you want 90CRI then it has to be the bridgelix gen3, if you talking 80CRI then they will probs be pretty close.
i imagine it will come down to price the h influx have never been the cheapest way to build a light.

Yeah but they pack real good density on those middle strips, they are somewhere in the middle of the 3 options in each length when it comes to lumen/dollar.
I honestly don't mind 80CRI, sure, I'd like higher with the same output.... 6 bars will give me about 300W of lm301B in a form factor designed for a 3x3 It should penetrate like a motherfucker.

I think Q series is a tad better effeciency, but looks like maybe you'll have to buy twice as many? Anyways, I attached the .pdf..

That is what I bought the Q series!
heat sinks finally came(18)
duty on top of everything wholly that was too much gunna just use aluminum beams might be cheaper for rest of light.
off to look at XLamp® XP-E2 Photo Red (660 nm) and Far Red (730 nm) LED's
they are going with those
gunna build a super fluence

420 nm has a peak in the stomata aperture spectrum. Iirc 360 and 280 aswell. Theres a paper on that somewhere but i guess youve already read em all ;)

i just wish cutter could do 420 on their solstrips. Or a 660/420 hortistrip from ledtech.

I was looking at numbers after the whole HGL thing. A 2700k 90cri strip (as per tekniks vesta tests) and a 9/1 red-blue strip should basicly copy that spectrum on a one to one basis of wattage and strips. At higher efficiency and less than a € per w for the chips, using cutter and led-tech

We do a full range of Semiled strips from 385nm to 430nm but only in 280mm, Semileds in image below. We could certainly do 660/420 mix version. What ratio?

Cheers

1)I would like a price on the following formula for
strips 560 mm. as long are they are evenly spaced out I do not care what goes on which strip.
I want to know if you can build me 20- strips @ 280mm.(up to 1120mm long which is better for me but of course less strips as they are longer)
This may require two profiles because of diode choices but if you can and
prefer all the on same with a mix is fine but if two profiles are required to suit my request that is ok.
I am sure you can suggest a simple way to build something to suit this formula.

here is list spread over 15 strips @ 280mm long, width to suit build requirements .

30 x SemiLEDs 390-400nm UVA LED
30 x SemiLEDs 400-410nm LED
30 x SemiLEDs 410-420nm LED
30 x SemiLEDs 420-430nm LED
30 x CREE XP-G3 Blue LED CREE XP-G3 ROYAL BLUE ( order code XPGDRY-L1-0000-00601)
60 x CREE XP-G3 Photo Red LED (order code XPGDPR-L1-0000-00G01)or best available
30 x CREE XP-G3 Far Red LED ( order code XPEBFR-L1-0000-00901) or best available
2)suitable driver(s) to power strips listed priced as may need different voltage for the Cree XP-G3 vers the SemiLEDs
3)full tunability for entire spectrum including the
ability to be run by something like this controller
in link below is a must built into strip(s).
https://www.cutter.com.au/product/storm-x-led-controller/
Please suggest what you feel is best suited without overspending that is just an example
future proof it a bit if u sell system like that which i hope you do something that can be expanded to control hvac via circuit board as well would be great
4)Heat sinks requirements and if you sell them, price, if not what is required per each profile strip.
if possible heatsink USA is there a profile suited to above strips ?
If we can work out a price they are sold
do you require all upfront?
I would like to buy something really soon provided pricing within
what I feel it reasonable so let me know how you want to proceed
PM message me if you like or I can email if given email to do so.
I can also call if easier
you will require address details you can get me a shipping cost as well but
not here that part how?
Ontario Canada.
Thanks

Will they continue to sell chips etc under the Cree name, I wonder?

@ttystikk
To me I doubt it.
This is huge company with many well known brand names under their belt.

Why walk away from millions in brand recognition let alone reprinting , changing websites, signs etc it never ends for costs.
I hope nothing changes except that maybe R and D gets a huge boost then look out!

Ideal makes all kinds of great stuff. Their tuff tote and legacy pro toolbags are an electrician's dream. They make all sorts of useful products and they'll surely make great use of their cree asset.

You can test your ideal diodes with an ideal multimeter, then install them with ideal hand tools, with the joy of using quality components.

Found mine last year at rapidled but I've also seen them on e3ay. Don't know if they still have them but seems cutter has Semileds too. Those 10w chips are too expensive, 430nm cost half that much and in 365nm they cost +20€, lol! You can also find Epi's with these wavelength but I would rather take Semi's.

Yeah it is nuts, In my local currency the H_I is R550 for 7910lm total
and the Q is R618 for 7360lm
you get 5% more light for your electricity on the Q though than the H_I

with things being this close you would likely not remember the extra expense taking one over the other, what do you think?
The high-density strips put down a fifth more light in the same area

I see purple but it is healthy, it just changed the top of a tomato plant from green to purple, but my gosh does it's leaves ever smell , never smelt a tomato plant stronger in my life and have grown them all my life outside.
This has nothing to do with nute's,
it is the light doing it.
test will be how do the taste which
I see have a few tiny tomatoes starting.
time will tell.
fresh food in winter available that tastes like outdoors now that would be worth alot here to me
vers mexico picked green and ripened by gas covered in chemicals no thanks.

Yeah, purple and UVA wavelength have a strong effect on the taste but also on nutrient content. Antioxidants, vitamins and other medical useful components are also increased. Considering that the nutrient content in tomatoes has practically halved since 1980 that's an important point. I'm pretty sure within the next years more an more professionels will use such wavelengths to get a better endproduct.
Last year I had a basil, a thyme and a rosemary plant for only 4 weeks in my little veg area where I have a 2ft reptile bulb and ~150w LED. All 3 have changed their smell and the tops of the rosemary plant was sticky like hell. If you have touched it you could feel it on your fingers. Not as much as when you touch fresh buds but the smell was incredible; much more like without UV light. The basil turned almost completely into a purple basil and the thyme plant got also a much stronger smell but only the stems got a purple tint.
So, yeah! It works and it seems to be the missing factor in greenhouses.

I'm pretty sure Mark can help and create strips with 420/660nm strips or 420/480 and 670nm if you want.
