    Led COB 30 watts Utilisées pour faire une serre à semis Je les utilise avec une puissance de 3 watts, ce qui évite la disspiation thermique. Pour limiter le courrant à 100 mA (sous 30V), j'utilise le circuit CL6 de Microship. Le résultat est très convainquant.

    Great 50W LED DC chips for planting. Blue and red spectrum for green plants growing. Very powerful and the plants are growing well under this light. Works fine low heat production but you have to put it on the aluminium heatsink to work fine. I like that COB chips, easy to mount and easy to operate with the aproprietary DC constant current driver.

    Great vaule LED grow chips for planting the vegetables or flowers. It has a full spectrum needed for plants to grow and bloom. Its a DC powered from constant current powersource and also need a big heatsink to cool it down. Better is also ad an ventilator to it to preserve a long life of the chip. Very great thing.

    produit compact, éclaire 1,5W à 27V, 3W à 28V avec échauffement important au delà nécessitant un radiateur + pâte thermique. La surface pour souder + et - est faible et la soudure n'y adhère pas facilement.

    All 12 LEDs that I bought worked as advertised. Packing was poor- but these are sturdy items, so it didn't matter.

    Eclairage relativement fort sous 30 volts et 100 mAh pour le modèle 30 watts. Avec ces valeurs, pas besoin de refroidir.
