No, i was saying just put it in as is, i dont wanna advice anyone to saw things in half even though it looks like you could reasonably do it if technical minded. But just dim it down a bit. Looks like if it fit. Since all rows light up the same id just write off those diodes and use it.

Just use it at half power, should work fine.

No ksf from teknik. Just looking for the best numbers we can get. Previously there were regular blux 2700k 90cri available thru led-tech which also scored slightly better than f90 in photon/w.

Yes, in lum/w but not in photons per watt according to testing cited.

Im not sure but id imagine the numbers being similar over brands For efficiency numbers you can use TEKNIKs here onsite (i think they should come up in bridgelux eb gen3 in the search option) and the ones on led-techs web for f90. Iirc correct standard ebs 90cri 2700k came out as 2.66 and a...

OP: this could just aswell be a dodgy dimmer, i suggest trying the light with dimmer disconnected before blaming a faulty driver. If no joy then by all means warranty service, but if this is just a dimmer then dont send your light away for service, just replace the dimmer.

From the cree blurb about these: i understood that theyre targeting stable red % content in order to make it easier to calculate how much more red to add thru monos. On that spikey 90cri spectrum: ive only ever seen it tested once at led-tech (bridgelux F90) and it looks like the diodes are...

I was off course referring to adding this to a led fixture, indeed no point in adding it to hid.

Lol, Its been years since i started hearing about your HID loving cat, when do we get to see him?

If you want to add infrareds to your grow then why not use incandescent/halogen? They have full coverage of the infrared while IR leds only cover a narrow band. It also is very good at hitting those 660-700nm which leds have problems to target due to inefficient diodes in that range.

Checked the spectrum on that one and i cant really see it going down to 280nm, major drop off under 400nm. But its got continuous coverage of anything in between while leds + supplement usually has some gaps.

Ok, then forget about the third board. All you have to do is to figure out the hanging and then connect again using series connection. Driver + first board +, first board minus second board plus and then second board minus back to driver minus. The trick is to figure out how much wire to use...

Generally for spread id rec 3 boards over 240 driver for that space. Spreading the watts out a bit means a bit less hangheight and more light onto cannopy. If youre already setting up for small plant/big plant youd be able to use 2 boards on 1 plant even angling the second board in. And since...

What youre talking about is just hanging several single boards but with one large driver. The only issue here would be the wiring, not pulling it out of the pushins while working around it. You can hottglue a wago onto one of the heatsink fins so that youre main wiring is going into the wago and...

Start a thread, put down space size, vented or sealed, and budget and theres a good few peeps here that can help. If youre struggling with finding parts like drivers why not try octapart, search engine for part nrs between different distributors.

Ooopsie, shoulda read thru more than the first post

Dude, why not ask quest themselves?? Ive made queries with them and they were very helpfull. Love our quest, especially the external control option.

Im pretty sure that qb96 spectrum has been changed from what it used to be, used to be higher 660 than 630 peak if im not remembering bonkers. I like 90cri phosphors to target 630 though, the 630 diodes tend to be crappy ppf/w

The qb96 has red supplementation of both 630 and 660nm which is somewhat different to most other boards made by HLG and the like. White + 660 boards usually end up with a bit of a dip around 630nm.
