Без экспонометра я не могу сказать вам, насколько он яркий, как 400-ваттный MH свет, но он определенно не мудро смотреть on that. It has a small fan to cool the LEDs, it's a bit noisier than the traditional light, but that's not a problem. After a month of use, there are no complaints, and the reduction in electricity and waste heat bills is welcome for growing microgreens for our table.
