ViparSpectra P4000 450W Full Spectrum LED Grow Light

The ViparSpectra P4000 450W LED Grow Light is a high performance full spectrum fixture engineered for serious indoor growers who demand exceptional canopy coverage, high efficiency, and consistent plant development. Featuring a redesigned diode layout, precision dimming, and advanced passive cooling, the P4000 delivers powerful PAR output while maintaining uniform light distribution across large growing spaces.

Powered by 1,960 high intensity SMD LEDs, the P4000 produces an optimized full spectrum consisting of 3000K warm white, 6000K white, 660nm deep red, and 730nm far red IR wavelengths. This balanced spectrum closely mimics natural sunlight, supporting vigorous vegetative growth, abundant flowering, and improved harvest quality across every stage of cultivation.

The upgraded diode arrangement creates an exceptionally even PAR map with deeper canopy penetration, helping plants receive consistent light from edge to edge. A precision dimmer knob allows growers to adjust output from 5% to 100%, making it easy to tailor light intensity for seedlings, vegetative growth, and flowering.

Designed for long term reliability, the P4000 utilizes a large solid aluminum heatsink for completely silent passive cooling. With no moving parts or fans, heat is efficiently dissipated while extending component lifespan and reducing maintenance.

Ideal for grow tents, grow rooms, hydroponic systems, aeroponics, aquaponics, and greenhouse applications, the P4000 combines commercial level performance with energy efficient operation for demanding indoor cultivation.

Advanced Diode Layout

The updated diode distribution creates a highly uniform PAR map that reduces hotspots while delivering deeper canopy penetration and more consistent plant growth across the entire cultivation area.

Optimized Full Spectrum

The balanced spectrum combines 3000K warm white, 6000K white, 660nm deep red, and 730nm far red infrared wavelengths to support every stage of plant growth from germination through flowering.

Precision Dimming

The integrated dimmer allows smooth brightness adjustment from 5% to 100%, giving growers complete control over light intensity throughout every growth phase.

Silent Passive Cooling

A heavy duty aluminum heatsink efficiently dissipates heat without cooling fans, providing silent operation, improved reliability, and an extended service life.
