Id consider these:
www.cutter.com.au
The 3000k90cri with uva.
Ebs are good aswell but calculate running them no harder than 15w, they are a plastic base versus aluminum. They are also hard to source in 90cri.
Im a fan of 90cri, you can allways get more intensity by more power but you cant really change spectrum without new chips.
The extra uv seem to give some extra potency and also helps with transpiration, happier plants that tend to pray more.
These would make nice for a fullcycle light.
Dont make price your main sticking point when you design your light.
Another similar light would be @Grow Lights Australia High Light uv boards aswell; very nice flower and less work but maybe not in stock.
SSK-1560ZGE-UVABoost White + UVA/Violet Led Strip | Cutter Electronics
The SSK-1560ZGE-UVABoost Board has 112 leds spaced on 0.5mm pitch for beautiful blending and maximum utilisation of the PCB. Solderless terminations

Thanks for the input. Would you go 3000k or the 2700k for flower only?Id consider these:

Marginally 2700k but theyre not in stock, and i think they wont be for some time...
3000k will be absolutely fine though. Its pretty much exactly the same except for a bit more blue. The extra blue is good for opening the stomata, more transpiration more nutes in the plant and less troublesome growing, less bleaching etc.
The highlights would be very similar to this but in 2700k 90cri base. But also likely not in stock.
If you want the extra red you can still add it later if you feel you need better results.

Also would you say they are better than the straight 3k Cree strips I linked ? I’m trying not to let price affect my decision too much but it’s ha
would you say they are better than the straight 3k Cree strips I linked ? I’m trying not to let price affect my decision too much but it’s hard when some strips are twice the price. Would 10 strips be ok over 3x3 space ? Thanks.

Imo yes, better flower. Yield is simlar or a bit better, a bit faster finish, they just look like they are a bit before the 80cris. You can reach similar results by adding reds but i prefer the 90cri way: whites are based on blue chips which have superior thermal characteristics. So i try to get as much red as i can from white chips. Ymmv. Everybody has an opinion.
Also the actual strip of cutter is aluminium which is very nice in comparison to plastic. And you would never have to add any uv cause its already there. Stronger in both red and blue side of the spectrum.

Make sure you are comparing in us dollars on both sides, aus $$ isnt very strong. Also if you talk to cutter you might be able to save something on import taxes, with digi forget about it

Ok you’ve made my mind up. But how many for my space? I do high density sogs 16 rooted clones straight to flower in a 900x900mm space . So I want a real uniform light over the whole canopy. I can’t get a response from mark, I’ve been trying since Tuesday ( last time we spoke, then nothing) his last response was that he could do a 2700k + 4000k for 3050k 90cri. And the spectrum would be exactly the same? I don’t see how with the extra blue but what do I know.

Its actually harder than what one thinks to get even cover with 560mm strips in a 900-1000mm squared space. My best bet is using 4 boards but then youre back to square one. If you go with strips then use some strips as perimeter on the sides of your frame in a square and then some strips going across. You want about 20% less watts per area in the centre to the best of my knowledge.
Cuttter can be hard to reach, try the chat section on the website but during aussie hours.

Tried all that still nothing. This is what I got. But will 10 of the crees be enough? Boards would be nice but seem harder to find unless going for the Chinese knock off from eBay etc.

Id use more, i like to push less per strip. 40w per strip means you need more than just some tape and u-channel for thermal managmeent. imo. I push my vestas around 20w and it works quite fine but they can be tricky with tape due to warping.
Its hard for me to answer on marks details.
If anything the left to right strips: make them closer to eachother in the top and bottom so to even out the spread.
Thats very high intensities for growing and im pretty sure youll see some deficiencies and maybe bleaching. But with the extra uv spread this should be more easy to manage. Its also over 40w per square foot, diminishing returns...
Extra power dont hurt in theory but tends to in practice, if the dial goes up to 11 people tend to try to get there no matter what.
But the highest ppfd readings ive seen not leaving an indoor plant in tatters was with a similar spectrum but with a hard core, dwc hydro setup.

Ok I’ll grab maybe an extra few and figure out how to run them softer. You’ve been a big help mate cheers. I’ll get some ordered and do some more reading on wiring and drivers. Thanks

Hey budsame here im struggling get through to mark / @welight . last contact about a week ago, asked a follow up question no reply...resent mail, nothing...

@welight can I get an email back please. It’s hopefully the last email you have to reply from me. I’ve tried the chat on your website, I’ve tried pm on this site and I’ve tried email ( a few minutes after your last reply) and I’ve had nothing back although you have been active on this site. As a customer it’s stressful buying something online to then hear nothing for days on end and not recieve any shipping information. I changed my order a day after I placed it ( slightly cheaper ) and have been asking for a refund since on the outstanding balance. I’ve tried to keep this private but I’m losing patience. Please can we get this resolved so we can both move forward. Cheers

I placed an order (#20437) on July 6th and still have not gotten any email back on shipping dates or reply on delay. After the order you said it would be sent out that week in email.

I have had great results running 7 strips 90% on 1 inch heatsinks. same pattern thats drawn up, 5 then 2 just inside a 3x3 spacing. 480w 48v. hot but you can hold the heatsink for a couple seconds. only pattern I want to make going forward. Still waiting to see how long before the thermal tape comes off. Screws are best. I like to throw real world growing issues at these builds, spacing and penetration is different when there are plants involved and your PAR doesnt need to be as high as bulbs either. With LED cultivation its a balance of proper ppm/ec AND PAR/PPFD more than ever. like yin and yang. same results from 1000w HPS and 1000ppm as I got from 600w LED and 700ppm.
please post your findings if you are able to finish this build.
