The IONGRID S44 indoor LED grow lamp features a unique halo design that maximizes plant yields by providing uniform coverage and deep light penetration. Utilizing Samsung LM301H diodes, this full-spectrum LED grow system is ideal for all stages of plant growth, from germination to flowering. Its raised LED driver and aluminum frame with thermal compound ensure efficient heat dissipation without any noise. Additionally, the included digital controller allows for expansion by pairing with other LED grow lights using expansion dongles (sold separately). This grow light is specifically designed for use in grow tents with reflective Mylar lining and is suitable for cultivating a variety of plants, fruits, and vegetables. Each unit is plug-and-play and comes with rope hanging hardware for easy installation. Part of the UIS™ platform, this product can seamlessly integrate with other grow devices and smart controllers to create the perfect 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 grow stages.
  • Linear bar light design adapted into a 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.


These light-emitting diodes are arranged in a halo ring form factor, which allows for even coverage and deeper penetration. This lighting maximizes your grow tent’s capacity and growth potential by expanding the amount of usable growing space and reaching past your plant’s canopy. The diodes’ arrangement also enables the LED grow light to achieve commercial bar light performance and provide full coverage in 4x4 spaces.


The IONGRID S44 comes with a programmable controller that enables efficient 0-100% PWM dimming, allowing for customizable light cycles of up to 24 hours for both on and off periods. It also boasts baseline brightness levels and backup memory for uninterrupted operation in case of power loss. Additionally, its detachable controllers can be mounted remotely and have extension ports for programming multiple LED grow lights.
