The Pack x4 SpectraPANEL X320 delivers 1,280W of full-spectrum light across your entire grow area. Achieve PPFD levels for high-intensity flowering (800-1,200 umol/m2/s) over 4+ m2. Ideal for 2.4x2.4m grow tents and professional grow rooms demanding consistent, heavy harvests every cycle.
BloomLED patented Daisy Chain system connects all 4 panels in series using just one wall outlet. The 1m connection cables are included, installation takes under 15 minutes. Manage everything through a single timer or smart controller, reducing cable clutter and simplifying your electrical setup significantly.
The SpectraPANEL X320 full spectrum covers 380-780nm plus IR: blue light (400-500nm) for vigorous vegetative growth, deep red (630-680nm) and far-red (720-740nm) for intensive flowering and resin production. One spectrum setting from clone to harvest - no bulb changes needed throughout the entire grow cycle.
At 2.7 umol/J, the SpectraPANEL X320 ranks among the most efficient horticultural LEDs. Up to 40% electricity savings compared to equivalent HPS. Investment typically pays for itself within 12 grow cycles through energy cost savings alone.
Each panel features a high-performance anodized aluminum heatsink and ultra-quiet fans (under 35 dB). LED junction temperatures stay below 65C, ensuring 50,000+ hours of life with less than 20% lumen depreciation (L80). Perfect for enclosed grow spaces where heat and noise are critical concerns.
Every SpectraPANEL X320 is designed and tested in BloomLED French laboratories. CE and RoHS certified, meeting the strictest European electrical standards. 3-year warranty on all manufacturing defects, France-based technical support responding within 24 hours to all your cultivation questions.
The SpectraPANEL X320 is powered by latest-generation Samsung LM301H LED chips - the world benchmark in photonic efficiency at 2.7 umol/J. A photon flux of 2,700 umol/s per panel (10,800 umol/s for the full pack) ensures your plants receive precisely the right spectrum and intensity at every growth stage. The integrated LED driver delivers stable, flicker-free power, reducing plant stress and maximizing continuous photosynthesis throughout the entire grow cycle.
Thermal management has been completely redesigned by BloomLED French engineering team. The extruded aluminum heatsink combined with ball-bearing fans (30,000-hour rated lifespan) keeps LEDs at optimal temperature at all times. Heat is directed away from the canopy toward the rear of the panel, reducing the cooling load in your grow tent and lowering HVAC requirements compared to equivalent HPS installations. For a 2.4x2.4m tent with the Pack x4, expect approximately 400W less cooling demand than traditional HPS lighting.
Light uniformity is the secret to consistent, high-yield harvests. Through secondary diffusion optics integrated in each SpectraPANEL X320 and correct 2x2 panel positioning, you achieve a PPFD uniformity coefficient above 85% across the entire canopy. Every plant - center and edge - receives nearly identical light for synchronized growth, uniform flowering, and consistent yields harvest after harvest.
In intensive flowering, the Pack x4 optimally covers 2x2m (4m2) at 900-1,100 umol/m2/s PPFD measured at 60cm from the canopy. In vegetative growth (400-600 umol/m2/s), coverage extends to 2.4x2.4m (5.76m2). These values assume all 4 panels correctly positioned in a 2x2 configuration in your grow tent or room.
How does the Daisy Chain installation work? Is it beginner-friendly?Yes! Daisy Chain installation is designed for quick, accessible setup. Hang all 4 panels side by side. Connect panel 1 input to the wall outlet, then panel 1 output to panel 2 input, continuing to panel 4. All connection cables (4x1m) are included in the pack. Complete setup takes under 15 minutes.
Is the SpectraPANEL X320 suitable for cloning, veg and flower?Absolutely! The full spectrum covers all growth stages. For cloning/germination: 20-40% intensity at 80cm. Vegetative stage: 60-80% at 60-80cm. Flowering: 100% at 40-60cm. No need to change lamps between stages - one spectrum calibration handles the complete grow cycle from first sprout to final harvest.
Can I expand the Pack x4 with additional panels later?Yes! The Daisy Chain system is modular and expandable. Connect up to 6 SpectraPANEL X320 panels on a single 16A circuit (3,680W max). For installations beyond 6 panels, create two independent chains on separate circuits. Your lighting infrastructure can scale with your growing operation without replacing existing hardware.
What is the actual power draw of the Pack x4?Each SpectraPANEL X320 draws 320W at full power (measured at the outlet). The Pack x4 thus consumes 1,280W at 100% intensity. With a dimmer at 80%, consumption drops to approximately 1,024W. Compared to an equivalent HPS setup (2x1,000W + ballasts = 2,000W+), the Pack x4 saves around 720W per hour of operation.
The Pack x4 SpectraPANEL X320 is the professional lighting solution trusted by serious indoor growers. With 1,280W of full-spectrum output, BloomLED exclusive Daisy Chain system, and a 3-year French warranty, it is the most cost-effective LED investment for large-scale indoor cultivation.
