LEDs Grow Light Full Spectrum Vegetable and Flower Indoor Plants Growing Lamp for Hydroponic Greenhouse

-1*: The use of materials is too economical, the assembly is sloppy. The large, hot PCB (printed circuit board) is glued only in the middle to the very thin, 1 mm aluminum plate, they do not touch anywhere, the plates are curved, the glue is thick. The curved PCB must be carefully removed from the curved plate. The surfaces must be cleaned and coated with thermal paste. The PCB must be put back in place by securing the four corners with screws. This way, the whole thing stays at a temperature of 75-80 degrees without additional cooling. I think it will quickly fail without modification. -1*: "100 W" is only 69 W (230V*300mA), "200 W" is only 133.4 W (230V*580mA) ... Why further dumb down the already stupid masses? "full spectrum" is what we use for general lighting. These and similar ones are not full spectrum LEDs. On the contrary, that's why their light is purple, as they don't emit the green range that plants can't use.... Whether the efficiency is better from a cultivation perspective, whether the energy in the missing range is transferred to the red and blue range compared to a truly full spectrum, with the same power consumption, can only be proven with laboratory measurements.... It's total nonsense that CH2O is a plant product... formaldehyde..?!? what's up..?!?
