GAVITA 6/750 400V EL DE LAMP

Description

GAVITA 6/750 400V EL DE LAMP is the 750W double-ended high-pressure sodium lamp from Gavita, engineered to deliver exceptional photon output and spectral consistency in Gavita’s 400V enhanced lighting system — the professional benchmark for commercial controlled-environment horticulture worldwide. We have been recommending Gavita Pro lighting to UK growers since 2017 as the reference standard for commercial grow room lighting performance and reliability.

Why Gavita’s 400V Double-Ended System Sets the Commercial Standard

Gavita’s Pro series operates at 400V rather than the standard 240V used by conventional HID systems, and this higher operating voltage fundamentally changes the lamp’s electrical and photometric characteristics. At 400V, the arc tube can be driven at higher efficiency, producing more photons per watt of electrical input than equivalent 240V HPS systems. The double-ended lamp design mounts the arc tube horizontally within the reflector, supported at both ends — eliminating the single-ended lamp’s mechanical stress on the base and allowing the arc tube to be driven harder over a longer operational life without the plasma arc instability that limits single-ended 750W lamps. The result is higher maintained lumen output, better spectral consistency across the lamp’s rated life, and the extended replacement intervals that commercial operations require to manage lamp replacement costs efficiently. The 6/750 designation indicates 6,000K colour temperature with 750W output — the combination that Gavita has validated for peak commercial flowering performance.

Compatibility Requirements and Commercial Integration

The Gavita 6/750 400V EL DE lamp requires a compatible Gavita 400V electronic ballast — this lamp is not compatible with standard 230V digital or electromagnetic ballasts. The Gavita Pro controller and ballast system is a professional-grade installation requiring appropriate electrical infrastructure. Replacement should be scheduled on the Gavita recommended interval — typically every two years in commercial continuous operation — to maintain the system’s measured photon output per watt. For UK commercial operations building or upgrading to the Gavita Pro system, the performance, reliability, and agronomic data supporting Gavita’s commercial position make it the professional choice.
