Why the Update & What’s Changed in 2026 Version？

Following Samsung’s strategic adjustment in its LED chip portfolio,  the SE Series has been engineering-upgraded. Change to Bridgelux diodes.

The new version features high-performance LEDs with an increased diode count, ensuring that light efficacy, PPF output, and light uniformity remain consistent with the previous Samsung-based version.

All key performance specifications are maintained to deliver the same reliable growing results.

High Efficacy & Uniform Lighting: SE4500 320W LED grow light designed with 3 LED bars to provide more even canopy coverage, especially to the outer edges of cultivation areas. Achieving an impressive PPE of 2.85 umol/J. For 70x140cm Grow Tent, 4-Inch Inline Fan.

Optimized Light Spectrum: with Spetrum 660-665nm,2800–3200K,4800-5000K, which supports all stages of plant growth, from seedling to flowering. The dimming knob is ideal for growers to adjust the light intensity according to different growing stages.

Efficient Cooling: Bar light design and aluminium material on the back contribute to better airflow and great heat dissipation. Reducing the risk of heat damage to plants and allowing for closer placement to the canopy without causing burning.  Efficient light output and lower heat can lead to faster growth cycles and quicker harvests.

Daisy Chain Dimming: The dimming knob is ideal for growers to adjust the light intensity according to different growing stages.

The daisy-chain function allows you to connect up to 50xSE4500 indoor plant led grow light – dimming multiple lights simultaneously. Widely applied in the commercial growing (horizontal and vertical), grow rooms, home grows, grow tents, hydroponics.
