Who This Is For

  • You are prioritizing vegetative health because weak root systems in early stages lead to poor yields during flowering.
  • You are building a scalable facility because managing individual timers for dozens of lights is a maintenance disaster.

What We Found

  • We always remind people that this unit stays dark until you plug in the iLogic controller to wake it up.
  • The passive cooling on these bars is impressive and keeps the room temperature much easier to manage.
  • The Samsung LM281B+ Pro chips provide a very clean white light that makes spotting leaf issues much easier.

What Users Say

  • Commercial growers say they cut down on labor costs by networking hundreds of these units to a single controller.
  • Users who swapped out older veg lights say their mother plants stay much bushier with tighter nodal spacing.
  • Facilities in humid climates report fewer electrical failures thanks to the genuine IP65 waterproof rating.

Iluminar iLogic FS Plus 340W Full Spectrum LED Grow Light

The foundation of professional indoor cultivation begins at the seedling and vegetative stages. The Iluminar iLogic FS Plus 340W is engineered specifically to kickstart plant growth, delivering an intense, vegetative-focused spectrum that ensures your crop develops the strong root systems and healthy leaf structures required for a high-yield harvest. As a core component of the Iluminar Lighting ecosystem, this fixture provides a seamless transition for plants moving into high-intensity flowering environments.

Delivering a potent output of 950 µmol/s with an impressive efficacy of 2.8 µmol/J, the iLogic FS Plus 340W provides the precision light intensity needed to maintain robust mother plants and accelerate growth cycles. This fixture is equipped with premium Samsung LM281B+ Pro LEDs and Honglitronic SMD3535 660nm LEDs, creating a specialized light recipe that optimizes energy consumption via a high-performance Sosen LED driver. For those looking to scale their operations, this light can be integrated into a massive network of up to 256 fixtures when paired with an Iluminar iLogic Plus RS-485 Controller.

Built to endure the humid conditions of modern grow rooms, the iLogic FS Plus 340W features an IP65 waterproof rating and a durable aluminum heatsink for passive cooling. While this model is optimized for the vegetative phase, larger facilities often pair it with the iLogic MS PLUS 700W for a complete growth-to-flower solution. Note: This grow light requires a separately purchased iLogic Plus Controller for operation; default settings are set to Null/Off to protect your plants during initial setup.
