Nova 1200W R5W

What It Is

The Flexstar Nova 1200W R5W is a commercial-grade, high-bay LED toplight in Flexstar's Nova Series — purpose-built for large-canopy indoor and greenhouse cultivation. Running at 1,200W true draw across a 120–277V input range, it delivers a measured 3,360 µmol/s PPF at 2.8 µmol/J efficacy, making it a straightforward spec for any operator currently running 1,000W or 1,200W double-ended HPS and looking to move to LED without a light-plan redesign.

The R5W designation refers to the fixture's full-spectrum output, optimized across the PAR range for vegetative and flowering production. At 33.97" long × 12.5" wide × 3.2" tall, the Nova 1200 presents a compact footprint relative to its output — reducing shadow canopy interference in both single-tier and multi-tier configurations. The modular convective thermal design dissipates heat passively, with the fixture rated to perform in ambient environments up to 40°C.

Who It's For

This fixture is targeted at licensed cannabis and hemp operators running medium-to-large licensed canopy — think multi-thousand-square-foot flower rooms, commercial greenhouses, or warehouse conversions where high-intensity toplighting is the primary light source. If your facility was designed around 1,200W HPS on a standard spacing grid, the Nova 1200W R5W slots in without a hanging-height or electrical infrastructure overhaul.

It's also a practical option for operators retrofitting older HPS rooms in phases. Because the Nova network supports up to 160 fixtures on a single controller, a facility can commission one room at a time and bring every fixture under centralized control as the build-out progresses — without mixing control infrastructure. The IP66 waterproof rating adds relevance for operators running high-humidity canopy environments or wash-down protocols between harvests.

Key Features

Adjustable light distribution is a standout operational spec: the Nova 1200W allows the light throw pattern to be tuned, which reduces photon waste toward walls and aisles and lets you tighten fixture spacing or push canopy closer to perimeter walls without significant PPFD falloff at the edges. This matters on any build where usable square footage is at a premium.

The IP66 ingress protection rating means the fixture is sealed against dust and high-pressure water jets — compliant with the sanitation and humidity conditions common in licensed cultivation. The fixture carries a 5-year manufacturer warranty and an LED component lifespan rated to 50,000 hours. Network controllability — up to 160 fixtures simultaneously — means the Nova 1200W integrates into a centralized lighting control scheme without per-zone controllers multiplying hardware cost.

How It Fits a Commercial Build

For a new build or room conversion, the Nova 1200W R5W is designed to match standard HPS grid spacing, which simplifies electrical rough-in and reduces engineering overhead. Its wide 120–277V input compatibility means it works with both 120V single-phase and 208/240/277V commercial circuits — an important consideration for facilities where electrical panel capacity is being managed carefully across multiple rooms.

Operators running large multi-room facilities benefit from the 160-fixture network ceiling: a single controller can cover a 10,000+ sq ft flower room at typical commercial spacing, keeping control architecture lean. Paired with Flexstar's supplemental undercanopy LED line, the Nova 1200W toplighting system can support a full tiered or multi-layer canopy strategy.
