Hi Guod, how we could achieve such a good PPFD Uniformity, i cant imagine how to got 80%. Maybe with many light sources, which are running on their own driver to dimm them up or down to achieve a even spread :?

in future i will do the same, thanks for the tip.

Hi guys i did a last footprint for this config(511watt@700ma-cxb3590-3500k). Height 31,5cm with reflectors and i added PPFD Uniformity in the title.

in US you can buy them at: https://www.cdiweb.com/Manufacturers/citizen/CatSum/LED-COB/?type=11131&manf=3039&NavType=1

your plants indoor and even outdoor looks mega healthy, must be the dutch green thumb :clap:

oh okey thanks for the math, i will do it now edit: PPFD is now in title, thanks jorge

Hello, do you grow in a tent? if yes then you will need exhaust air fan and a other small fan which moves the air for the plants in the tent.

i wonder if a reflector is even necessary at a 30cm distance, i think better without. But i will do tests with reflector and without, but tomorrow. yeah thats the way, how we should compare, i think

Here the footprint without reflector. Leaf test coming soon, need to smoke first:weed:

ideal yes i will beginn in 1hour

should i remove the reflector adapter too? if i remeber right, the reflector adapter act like a reflector.

Hello, Yes i will do that test, but i have to say that leaf will be not from weed plant. just from a normal plant with a bit bigger green leaf. Atm i dont have any weed plants:/

nice work Robincnn, Thanks for sharing

Hi , yes i will do later. Pretty nice footprint, Thanks Jorge. hm, i didnt even noticed that tab, here are the same 2pictures from "post#13" but now you can see the CRI tab

Hi, that was the first thing, what i was testing. In the picture which i post, you can see a lamp which use 3*cxb 3500k @ 1400ma. in the 2nd picture you can see the same light but dimmed down to 1V(with a 1-10Vdimmer ). I cant see big difference in the datas.
