Those strips are 19V right? Its not the best driver match as this driver will run a bit more efficient at higher voltage, under 70% /40V the driver becomes less efficient.

Yes, the strips are 19v. Is the efficiency loss significant? . Any combination of strips and conductor more suitable?

Either a hlg240-36A with voltage boosted or a 240-42A or B. A version means voltage regulation onboard but no external dimming.

I needed something for mothers but didnt have amperage to spare. Its a spectre phaser stretched to 9'

are you still happy with your F90s?
the concept is quite interesting, i wonder it havent cought more attention here.
would like to know the ppfd output, looks like its quite good.
"For traditional LED technology, higher CRI results in a lower efficacy. By replacing broadband red nitride phosphor with narrowband red Potassium Fluorosilicate (PFS or KSF) phosphor, the F90 LED products can achieve today’s CRI80 LED efficacy with a CRI of 90. "
would prefer the 3000K, which spectrum is given in the datasheet, above is only the 4000K
edit:
hm... checked the product sim on the quick and at nominal the 3000K are just 2.5ppfd, thats a bit average.
could be wrong, need a bigger screen to really check.

I can never get the horticultural rating to show on the Bridgelux product sim. How do you do that??are you still happy with your F90s?

downloading their XLS and open it.
prob a fake email works too.
used google sheets to open it.
qmol/J is to the right in the table, goes from 2.2-2.9, but i have no feeling for the F90 nomenclature and i am on a 13" notebook atm which is pita for sheets.
if youre on a bigger screen and open the datasheet in parallel you may can decipher the info you want.

Definitely an interesting spectrum. Curious if you would use just these strips for a build or pair them up with some sort of other spectrum?are you still happy with your F90s?

Either way will be cool to see some more results with the narrowband spectrums.

yeah, am curious too, just would need to get a way better picture of them before making any decission, but i honestly considered using them as the only light source (while i do have mono strips too i could alays add).
sadly lots of other stuff to do atm, so guess there is no time for a new build.
on the quick it doesnt look like i could win much in terms of efficacy to what i am using now, but could be wrong.

There's two types of F90 strips they have a high efficiency 90 CRI which is like 195-210lm/w
And the normal F90 which is like 172lm/w.

210 would be awesome, i just couldnt find a real product having this?
no strips linked there, but stating >200 lpw.
in this datasheet the max is 172 lpw.
just the links from the last page, nothing new.
210 ones sound awesome, when they have 210 lumen in the visible spectrum with all this red the qmol/s rating could look nice, but so far the max i saw was 2.9 in their sheet.
tempting maybe, but i should see how i get my place heated, and i cant grow over winter anymore anyway, otherwise i would be always in for using less wattage.
happy to hear reports of F90 users of course.
@MidnightSun72 have you been able to check the qmol/s (ppfd) now?

Yes I am able to see it now. It doesn't show up for every colour temp and CRI. Thank you.

thanks will have a look, no stock for these anyway, world sucks atm.

Yes, d8thc, an isomer? made from hemp(cbd isolate) Industrial hemp products can't be sold for human consumption here. Some companies are selling CBD extracts as pet medications – and some sell it to humans on the black market – but I haven't heard anything about D8THC here. Admittedly I'm not...

I think led-tech.de have these diodes and use them for their own strips. They made some ppf measurements which was kinda underwhelming.
Back to the day job for me...

how hard is it to get a dimmer on these led strips?
MidnightSun72
Well-Known Member
Dimmer is a component you add to the driver. And the driver needs to have dimming leads.

whould this be good for a 120x120 grow box? or even better is this good for growing? i am confused with CRI.

Those are 80CRI only. But ya I used the 3500K strips and been running 2 years now. They will grow fine dank on their own.
