Gavita Pro 1000e DE 277-347/400 Grow Light

The ‘e’ in ‘e-series’ stands for external control. These fixtures can be controlled centrally by a Gavita Master controller. This replaces the often cumbersome installation with contactors and clocks, and adds safety features such as automatic dimming of your lights at high temperatures and even a safety shutdown. We improved the electronics and changed the way the ballast is built, by mounting the PCB and warm components directly on the heat sinks instead of in a ballast bracket. The much cooler electronics result in a greater reliability and a longer life. The new design of the housing even increases that effect.

Complete fixture
The integration of ballast and reflector results in a compact fixture. No external lamp wires results in low EMI, which makes it easier to comply with FCC regulations. All our fixtures are FCC compliant.

Horticultural design
Our fixture is not a contraption of a remote ballast and reflector: it is a fixture designed as a complete fixture. The high quality white coating is durable and UV resistant. All the terminals are sealed with gaskets and contact and terminals are high quality.

Balanced fixture
The fixture is balanced, so it can be mounted by just two hanging points. This enables much easier installation by brackets from C-profiles for example.

400V lamp technology for high frequency electronic ballast
The high voltage lamp technology results in a better efficiency of the arc tube: more light for the same power (10-25% more than traditional single ended lamps)! These lamps are best suited for extreme high frequency electronic ballasts, creating a stable arc without acoustic resonance, assuring optimal output and a long lamp life. The smaller arc tube and outer balloon require the lamp to be nitrogen filled instead of vacuum, which prohibits it to be air cooled. Air cooling of the lamp results in lower lamp temperature, which results in sub-optimal light output, up to 15% less than specified. Therefore these lamps are not suitable for direct air cooled fixtures.
