Its six-bar architecture combines broad light distribution with a low-profile design, making it especially well suited to vertical farms, multi-tier racks, greenhouses, grow rooms and other controlled-environment facilities.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 400W Full Spectrum LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e Over 1,000 µmol\/s PPF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency:\u003c\/strong\u003e Up to 2.6 µmol\/J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl:\u003c\/strong\u003e 10–100% Dimming + Controller Ready\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOperating at approximately 385–396 watts depending on input voltage, the PerfectPar V400W delivers over 1,000 µmol\/s of photosynthetic photon output with efficacy rated up to 2.6 µmol\/J. BoulderLamp builds the fixture with Philips\/Signify LED drivers and LEDs from Cree, Osram and Samsung.\u003c\/p\u003e\n\u003cp\u003eThe fixture also offers considerably more control than a basic fixed-output light. Intensity can be continuously dimmed from 100% down to 10%, while BoulderLamp’s optional programmable lighting controller adds week-by-week scheduling, automated intensity changes, DLI-based lighting strategies and optional pulse-mode operation.\u003c\/p\u003e\n\u003cp\u003eAt just 2.2 inches high, the V400W provides a large lighting footprint without consuming excessive vertical space — an important advantage in multi-tier environments where every inch between racks matters.\u003c\/p\u003e\n\u003ch3\u003eOptimized for Vegetative Growth\u003c\/h3\u003e\n\u003cp\u003eThe PerfectPar V400W is specifically designed around the lighting requirements of vegetative plant development.

Its published spectral power distribution shows strong blue output around the 450nm region, a broad band extending through the middle of the visible spectrum and additional output in the red portion of the spectrum.\u003c\/p\u003e\n\u003cp\u003eThe resulting spectrum is tailored primarily toward vegetative horticulture while providing a broad range of photosynthetically active light.\u003c\/p\u003e\n\u003ch3\u003eContinuous 10–100% Dimming\u003c\/h3\u003e\n\u003cp\u003eNot every stage of plant development requires maximum fixture output. The PerfectPar V400W provides a full 10–100% dimming range, letting output be reduced substantially when full intensity is unnecessary.\u003c\/p\u003e\n\u003cp\u003eGrowers can match fixture output more closely to plant requirements rather than running the light at maximum power throughout the entire growth period.\u003c\/p\u003e\n\u003ch3\u003eWeek-by-Week Lighting Control\u003c\/h3\u003e\n\u003cp\u003ePairing the V400W with BoulderLamp’s optional programmable lighting controller expands the fixture into a more advanced automated lighting system.
