Flexstar Double-Ended HPS Horticultural Lighting Fixture

The Flexstar Double-Ended HPS Horticultural Lighting Fixture is a 1000W high-intensity grow light engineered for professional horticultural applications. It features a patented 3-angle adjustable reflector system with a 95% reflective embossed aluminum surface and is compatible with both double-ended HPS and MH lamps. The fixture supports a wide range of input voltages, five dimming levels, and is ETL certified, omitting the lamp for user customization.

Construction and Design
The fixture is housed in a durable body and measures 25.1 inches in length, 10.5 inches in width, and 4.9 inches in height. The unit weighs 14.1 lbs (net) and 18.7 lbs (gross). Each unit includes a 10 ft power cord for flexible positioning.

Optical System

• Reflector: Features a patented 3-mode adjustable reflector made of Italian Vega 95 embossed aluminum with 95% reflectivity, allowing the beam angle and light spread to be optimized for different growth stages and canopy coverage.

• Coverage Area: Provides a coverage area of 6' x 6' for vegetative growth and a more intense 5' x 5' area for the flowering phase.

• Lamp Specifications: Accepts double-ended HPS or MH lamps (lamp not included). The recommended lamp operates at 230V with an operation frequency of 100-120kHz. When paired with a double-ended HPS lamp, the fixture delivers up to 151,000 initial lumens and a lamp luminous flux of up to 151,000 lm. It has a lamp luminous efficacy of approximately 128 lm/W and a correlated color temperature (CCT) of 2100K.

Electrical Specifications and Controls

• Voltage and Current: Available in 120-240V and 240-277V configurations. Input current varies by voltage: 9.3A at 120V, 4.95A at 220V, 4.6A at 240V, and 3.85A at 277V. A 480V configuration is also available for high-power installation environments.

• Power Quality: Operates on a mains frequency of 50/60Hz with a minimum power factor of 0.99 and less than 10% total harmonic distortion (THD).

• Dimming: Features six selectable power output levels via a dial knob (600/750/825/1000/1150/EXT) that allow cultivators precise control over light intensity for applications such as crop steering or energy savings. This is supported by square-wave ballast technology for enhanced lamp stability and efficiency.

• Controller Integration: The fixture can be linked to a compatible controller to manage up to 160 lights simultaneously, enabling synchronized dimming and on/off schedules.

Thermal and Environmental Specifications

• Ambient Operating Temperature: -4°F to 104°F (-20°C to 40°C).

• Maximum Case Temperature: 167°F (75°C).

• Ingress Protection: Rated IP67, indicating complete protection against dust ingress and protection against immersion in water up to 1 meter.

• Cooling: The die-cast aluminum housing provides efficient heat dissipation and supports operation in high-temperature environments.

Warranty and Certifications
The fixture is backed by a 3-year warranty and is ETL Listed for safety.
