GL25

The GL25 is a detachable commercial grow light system built around a 250W main fixture and two detachable 250W sub-fixtures. The system can operate in 250W, 500W, or 750W configurations.

250W Main Fixture

The base fixture operates at 250W and forms the foundation of the modular system.

Two 250W Sub-Fixtures

Two additional 250W sub-fixtures can be connected to create the complete 750W system.

3.0 ± 0.1 µmol/J

The supplied source specifications list PAR efficacy at 3.0 ± 0.1 µmol/J.

250W / 500W / 750W

The detachable architecture allows the system to operate at three power configurations.

Passive Cooling

Passive convection cooling provides thermal management without active cooling fans.

IP67 Connections

Waterproof quick-connect components support the modular fixture connections.

Modular & Detachable Design

The detachable structure allows the fixture sections to be joined, separated, and configured according to the installation.
