Welcome VIPARSPECTRA 2022 Newest KS3000 bar grow light, with optimal full spectrum layout, dimmable knob, market-leading Samsung LM301H and OSRAM Diodes. It is an LED bar fixture designed to provide an excellent spread of high-density light to a 3’x 3’ canopy.

It features a state-of-the-art design and the best components on the market. We know the importance of uniform coverage and the perfect PPFD. With a well thought out design and the best components on the market.

What our Experts Think

• High-efficiency commercial grow lighting: The Mars Hydro FC-6500 Samsung LM301H EVO is a 730W bar-style LED grow light designed for serious indoor cultivation, including commercial and high-yield home setups.
• Premium diode technology: Uses Samsung LM301H EVO chips, known for high efficacy and strong photosynthetic output, improving plant growth efficiency and yield quality.
• Optimized full-spectrum output: Delivers a balanced spectrum (blue, white, and deep red) to support all growth stages from seedling to flowering, reducing the need for supplemental lighting.
• High PPFD and uniform coverage: Engineered bar layout provides even canopy light distribution with reduced hotspots, supporting consistent plant development across larger grow areas (up to ~5×5 ft).
• Strong energy efficiency: Around 2.9 μmol/J PPE, offering high light output per watt and helping reduce electricity cost per gram of yield.
• Dimmable and controllable design: Adjustable intensity allows precise control across growth stages, improving flexibility for different crop needs.
• Efficient thermal management: Bar-style passive cooling and external driver design help maintain stable operating temperatures and long LED lifespan (~50,000 hours).
• Commercial-grade build quality: Designed for long-term use in demanding environments like vertical farms and high-density indoor grows.
• Yield-focused engineering: Frequently chosen for high-yield cultivation setups where consistency, penetration, and canopy uniformity matter most.

Q&A

Maintenance Tips

• Keep drivers & heat sinks dust-free: Dust buildup reduces cooling efficiency and can shorten diode lifespan. Clean with a dry brush or air blower.
• Maintain proper airflow: Even though it has passive cooling, ensure good tent/room ventilation to prevent heat stress.
• Avoid full power at all stages: Use dimming during seedling/early veg to reduce stress and extend diode life.
• Check hanging height regularly: Maintain correct distance from canopy to avoid light burn or uneven PPFD distribution.
• Secure wiring & connections: Ensure AC input and dimming/control cables are tightly connected to avoid flicker or driver damage.
• Stable power source: Use a surge protector or regulated power line—high-watt LED drivers are sensitive to voltage spikes.
• Clean reflectors/bar lenses gently: Use microfiber cloth only—no alcohol sprays directly on LEDs.
• Avoid humidity exposure on driver: Driver is detachable—keep it outside high-humidity zones in grow tents.
• Inspect periodically: Check for flickering, uneven bar output, or fanless heat buildup changes (early warning signs of driver wear).
