The IONBOARD S33 is a 260W full-spectrum LED grow light designed to provide 3 ft. x 3 ft. coverage in indoor grow tents with reflective Mylar lining. Its Samsung LM301H diodes are algorithmically positioned to create uniform light distribution and deeper canopy penetration throughout germination, vegetative, and flowering stages.
A fanless unibody aluminum construction supports passive heat dissipation, while IP65-sealed components provide protection in humid and high-temperature grow environments. The built-in dimmer offers adjustable light intensity, and UIS compatibility enables expanded scheduling, grow-cycle, and app controls when connected to a compatible smart controller.
Key Features
-
Full-Spectrum Lighting: Uses Samsung LM301H diodes with 660nm, 730nm, 3000K, and 6500K light for multiple plant growth stages.
-
Uniform Light Distribution: Algorithmically positioned diodes provide an even PAR map, wider light spread, and deeper canopy penetration.
-
Adjustable Brightness: The built-in dimmer adjusts light intensity from 0% to 100% in 20% increments.
-
UIS Compatibility: Connects with compatible smart controllers for grow cycles, scheduling, app control, and additional programming options.
-
Expandable Lighting: Supports connection with additional LED grow lights when used with compatible expansion dongles, sold separately.
-
Fanless Heat Dissipation: The unibody aluminum board provides passive, noise-free heat dissipation.
-
IP65 Protection: Sealed components help maintain performance in grow environments with higher humidity and temperatures.
-
Indoor Growing Application: Designed for grow tents with reflective Mylar interiors and the cultivation of plants, fruits, and vegetables.
