Haha me too bro, sounds like some thing out of star wars or star trek .

First grow: Skoondawg's Soil - South African Bag Seed - HPS & CFL SCROG Cabinet 2016/17

Engaging the quantum boards, side clamps released, optimizing ratio to 1:16, dual chip warming up. Oh good my two minute noodles are done LoL we still have some ways to go brother, need to learn these things

At 68 lumens per watt I'm out lol. 65CRI

I sure wish I could find some of these bad boys somewhere. BXRC-17E4000-C-74-ND. They are 1750k but look at the beautiful flower spectrum. Peaks right at the 660nm area. I would build a small array right now with some of these at 1.5 chips per square foot.

 

[JimmyJames905]

I saw it and was wondering if it would add more red spectrum but citi spectral data sucks. It's also available in the 1818

Look at the red spectrum in the chip I just posted a pic of. Way better flower spectrum then ANY I have seen yet.

 

[fanleaf]

Heres a link. Scroll down to the 2nd spectrum graph and look at that 1750k. There you can zoom and see it clear.

Those are 100 lm/w but I think well worth it because of spectrum. Run soft at about 30w each and they should do even better. They hump right at 660nm where the Mccree curve shows plants use it most.

That's the decor series. Designed for low heat applications like displays, bakery, restaurant lighting.
It's funny that Bridgelux, an American company out of California, makes a light specifically designed not to yellow paper or dry your croissants but they haven't figured out that half the COB buyers on the market are using it to grow weed.
Lol.

Very true. And nobody has them in stock either.

 

[JimmyJames905]

What about the citi "warm plus" chips. I can't find the data. The data I can find doesn't give me wavelength.

I looked and looked as well. I would love to see a spectrum map of them.

 

[JimmyJames905]

Literally all I can find on the "vivid" series.

I know man. Cree, Citi, and others need to start adding the spectrum maps for 2700k and lower chips. None really do it.

Oh you mean the "meat chip". I can get those in Vero 18's.

haha "meat chip". I like it. I hope soon these manufacturers catch on to why their sales have skyrocketed soon and develop a horticulture series!!! That would be badass. H.C. series with a few different options.
