Optic 1 3500k COB

BRIGHT!

Bright as the sun!

The lights I like. Not a great range but a great output for the wattage. BRIGHT!

Great light! Little power. Lots of trichomes!

Wish the ppfd was higher I have put 3 of these in my 3x3 and still don't think it's enough

Great lights

Great lights!

Big fan of these lights! Not a lot of heat and the plants love them!

Love this. It stays pretty cool. It puts off GREAT light. It grows nice plants.

The Optic 1 LED is powerful and efficient enough. You should pay sufficient attention to the air flow if you use this because of its heat production.

The Optic 1 LED works nice as estimated. Free from deficit of the light yield, the LED is powerful and efficient enough for a small-scale growing. My only concern is its heat production, which would sometimes force me enlarge the lamp-to-plant distance. You should pay attention to the height of your grow tent if you use it.

buona penetrazione di luce . si arriva tranquillamente a 1g per watt
