Yup, you are correct about that....the idea of putting all those diodes together ina bunch was not great...
i have 4 of em and because of the overlap and how white the walls are right now i have the lights 30 cm farther than the maximum raccomended and im stretching the footprint to almost 7 foot wide...
Ive seen very nice compact shade grown buds in the room!! the penetration is incredible, but yeah i burned the hell out of the tops at my first try with those light because i couldt believe how powerful they were.....i wish they told me!!!
i also was unaware of the typical led burn signs...
They reccomend in flower a distance between 75cm -92cm.....i felt that its insanely close if you have more than one...
I feel like if you know this little trick they are totally worth.....
