Who This Is For

  • You are planning a 2x4 footprint because your space is limited and you need a high-efficiency footprint match.
  • You are choosing between fixtures because you want to scale up by daisy-chaining multiple units later.

What We Found

  • The passive honeycomb design keeps the heat down surprisingly well without needing a failure-prone internal fan.
  • The dimming knob gives you clean presets that let you ramp up intensity without guessing at percentages.

What Users Say

  • Users who daisy-chained several units say it simplified their cabling and kept their room looking much cleaner.
  • Growers who upgraded to this spectrum report they saw a tighter growth habit and better density at the finish.

Elufah NHI3200-24 320W 2' x 4' LED grow light | High-Efficiency Full Spectrum Solution

The NHI3200-24 provides a 320W lighting solution optimized for intermediate growers managing 2x4 foot footprints. It utilizes a specific blend of 6200K white, 437.5nm blue, and 730nm deep red wavelengths to drive photosynthesis across the entire plant lifecycle. The fixture achieves a PPFD efficiency of 3.0µmol/m²/s; PPFD measures the amount of light that actually reaches the plant canopy for growth.

In Detail

Elufah NHI3200-24 heat dissipation design

The NHI3200-24 handles thermal loads through a passive honeycomb heat dissipation design and foldable aluminum bars. This configuration allows for high light output without the noise or failure points of internal fans. The fixture carries an IP65 waterproof rating to protect internal components from high-humidity environments and foliar spraying. An anodized anti-corrosion coating further extends the lifespan of the hardware in active grow spaces.

  • Adjust brightness from 0% to 100% using the 5-level dimming knob.
  • Connect up to 20 fixtures via RJ12 ports for centralized control.
  • Deploy 840 individual diodes for uniform light distribution.
  • Utilize the 730nm deep red wavelength to trigger flowering responses.

Frequently Asked Questions

Will this light significantly increase the temperature in my 2x4 tent?

The NHI3200-24 uses a passive honeycomb heat dissipation design and aluminum bars to minimize heat buildup. While it does not require internal fans, you should maintain standard tent ventilation to manage the ambient air temperature.

Can I use this light for foliar spraying without damaging the LEDs?

Yes, the fixture carries an IP65 waterproof rating and an anodized anti-corrosion coating. These features protect the internal circuitry from moisture and environmental humidity common in active grow rooms.

Does the spectrum support the flowering stage effectively?

The spectrum includes 730nm deep red wavelengths specifically to drive the flowering response. This is combined with 6200K white and 437.5nm blue light to provide a full-cycle solution from seedling to harvest.

How many lights can I control from a single master unit?

You can daisy-chain up to 20 fixtures using the RJ12 ports. This allows you to adjust the brightness of the entire array simultaneously from one dimming knob or an external controller.

What are the dimming presets available on the knob?

The dimming knob features five preset levels at 20%, 40%, 60%, 80%, and 100%. It also includes an EXT setting for use with external RJ12 controllers.
