Question 45 x 50 CM microgrow

I have this closet of 45 CM X 50 CM and 1 Meter high.
Also i have 4 x Cree CXA 2530 Leds and 1 chinese Leddriver of 50 Watts ( Which actually give 59 Watts of power ), which is rated to give 32 -38 Volts and 1450 MA.
I know the CXA2530 runs on 36 Volts and i build the light and it runs really fine.
I use this driver to run all 4 of the CXA2530´s .

Now my question is, is this light to much, or to less for my space, or is it OK ?

Greets, nederwierie

That's 0,225m² or 2,4ft². With the old 30-35w/ft² rule 72-84w would be optimal and would provide you ~700-800μMol/s/m2 ppfd. You could add 3-5w UVA/purple(385/430nm) and 20w deep- and far-red(660/730nm, 3:1) on a second 25w/300mA driver or simply add another two COB's and a 20w/600mA driver.


BTW,
CXA2530 is indeed a 36v COB but you run 4 in parallel and each one gets only ~360mA. Corresponding to the datasheet the voltage required would be 34-35°C depending on case temps.

Thank you very much!
I was unknown about the 30-35 W/Feet rule and how to convert that to M2 but you made it clear to me.
I ordered another driver to make the W/FT complete.

Thnx!

Sorry for this late question.
Would it be ok to turn up the wattage to 100 Watts on this 0,225 M2 or would that be to much of the good?
I really wonder because i´m planned to add 2 CXA2530 CRI90 cobs extra but maybe 100 Watts is to much.
Also some extra Watts for some extra heat is welcome in this winter.
