This warranty reflects BoulderLamp Inc.'s commitment to quality construction and long-term reliability in demanding commercial cultivation environments.

BoulderLamp Inc. PerfectPar V400W FAQs

Why should I use a dedicated vegetative light instead of a flowering light? +

The PerfectPar V400W's spectrum is specifically optimized for vegetative growth, promoting strong root development, healthy leaf formation, and robust structural growth at a lower power consumption (400W vs 650W-990W for flowering fixtures). This allows you to reduce energy costs during the vegetative phase while still providing optimal light quality for that growth stage, then transition plants to higher-intensity flowering lights when they're ready to bloom.

What does the 1,000+ µmol/s output mean for vegetative growth? +

The V400W delivers over 1,000 micromoles per second of photosynthetically active radiation at just 400W, providing ample light intensity for vigorous vegetative growth. This PPF output is sufficient to promote rapid leaf development, strong stem growth, and healthy root systems during the critical early stages, while using significantly less energy than flowering fixtures.

What makes the component quality "premium" in this fixture? +

The V400W uses Philips/Signify LED drivers, which are industry-leading power supplies known for exceptional reliability and longevity. The LED chips come from three of the most respected manufacturers—Osram, Cree, and Samsung—each known for superior light output, efficiency, and lifespan. This combination ensures consistent performance and reduces the likelihood of premature component failure in demanding commercial environments.

How does the dimming feature work and why would I use it? +

When paired with BoulderLamp Inc.'s optional programmable controller, the V400W can be dimmed continuously from 10% to 100%. Dimming is valuable for acclimating seedlings and clones to higher light levels gradually, reducing stress during transplanting, or adjusting intensity based on plant response. The 10% minimum allows you to maintain extremely low light levels when needed without turning fixtures completely off.

What coverage area does the V400W provide? +

The six-bar LED array covers up to 25 square feet of canopy space, ideal for a 5' x 5' vegetative footprint. The slim bar design ensures uniform light distribution across the entire coverage area, promoting even growth rates and eliminating the need for frequent plant rotation during the vegetative phase.

Can I use the V400W for flowering if needed? +

While the V400W is designed primarily for the vegetative phase, it can be used for other applications including flowering in smaller-scale operations. However, for optimal flowering results in commercial facilities, BoulderLamp Inc.'s dedicated flowering fixtures (650W or 1000W models) provide higher intensity and spectrum optimization specifically engineered for maximum terpene production and yield during the bloom cycle.

What is pulse mode and when should I use it? +

Pulse mode operation (available as an option with the programmable controller) rapidly cycles the light on and off at specific intervals. Some growers use this technique to potentially reduce energy consumption while maintaining photosynthetic activity, or to simulate natural light fluctuations. This advanced feature allows for experimentation with alternative lighting strategies tailored to your specific crop requirements.

Is this fixture suitable for multi-tier systems? +

Yes, the compact 2.2-inch height profile and lightweight 20-pound construction make it ideal for multi-tier vertical farming applications. The lower heat output (1,313-1,350 BTU) compared to flowering fixtures also reduces cooling requirements in stacked configurations, making it especially well-suited for high-density vegetative propagation systems.
