Experience maximum plant growth and yields with IONGRID S33, the industry-leading indoor LED grow light featuring a unique halo design. Designed for use during all stages of plant growth, it utilizes cutting-edge Samsung LM301H diodes for efficient full-spectrum lighting. The raised LED driver and aluminum frame, combined with a thermal compound for quiet heat dissipation, make this grow tent light stand out. It also includes a digital controller and allows for expansion with additional LED lights using dongles (sold separately). Perfect for use in grow tents with reflective Mylar lining, this plug-and-play system comes with rope-hanging hardware for easy setup. Part of the UIS™ platform, this product is designed for seamless integration with other grow devices and smart controllers to create your ideal growing environment.


  • Innovative halo design produces uniform coverage and deeper light penetration to maximize plant yields.
  • Specially formulated with full-spectrum Samsung LM301H white, red, and IR LEDs optimized for all growth stages.
  • Linear bar light design adapted into four-sided halo form factor to achieve commercial lighting output.
  • Digital controller with daisy-chaining ports featuring PWM dimming, timers, cycles, and backup memory.
  • Air-suspended driver over aluminum heatsink passively cools LEDs to last longer and boost PAR output.


Featuring a halo ring form factor, the IONGRID S33 FULL SPECTRUM LED GROW LIGHT 300W utilizes a strategic arrangement of light-emitting diodes for even coverage and deeper penetration. This innovative design maximizes a grow tent's capacity and potential by expanding usable growing space and reaching beyond plant canopies. Additionally, the arrangement of diodes allows the product to achieve commercial bar light performance and provide full coverage in 3x3 spaces.


The system comes with a programmable controller with 0-100% PWM dimming capabilities for optimal efficiency. Users can set timers and create consistent light cycles up to 24 hours for both on and off periods. With baseline brightness levels and a backup memory, power loss will not impact programming. The controllers can be mounted remotely and have extension ports for programming multiple LED grow lights.
