The Lumii Black2 720/960w LED Grow Light is a versatile, modular, and dimmable full-spectrum LED grow light, expertly designed for extensive coverage of areas measuring 1.5m x 1.5m and beyond. This advanced LED grow light offers the unique capability to operate at either 720 watts or 960 watts, catering to varying growth requirements and energy consumption preferences. Moreover, it can be conveniently split into two separate LEDs, providing unparalleled flexibility to suit different growing setups and environments.

Efficiency & Coverage

The LED grow light fixture features an impressive operating efficacy of 2.9 µmol/J, with LED chips achieving 3.4 to 3.7 µmol/J. It delivers a maximum PPF of 2596 µmol/s at 960W, split between two 480W ballasts- far outperforming typical 1000W HPS lamps. Lightweight and easy to install, this versatile fixture consists of two interlocking halves, each with its own power socket. It can be configured as a single 6-bar fixture for 1.5m x 1.5m coverage or two 3-bar fixtures for up to 25% larger areas. The halves can be powered by one or two Lumii Black 600W Electronic Ballasts, with two ballasts increasing light output by at least 25%.

Modular LED Grow Light

The first of its kind; The Lumii Black2 720/960w LED is a completely modular LED grow light. Its modular nature means it can easily adapt to expanding or changing grow spaces, making it a long-term, cost-effective solution for maximising plant health and yield. This LED can be configured in 4 different ways. 

Option 1: Pair with a Lumii Black 600w digital ballast for an all in one 720w led grow light fixture.

Option 2: Pair with 2x Lumii Black 600w digital ballasts for a total output of 960w split across the 2 ballasts.

Option 3: The Lumii Black2 720/960 can be split into 2 separate light fixtures. Pair each half of the Lumii Black2 with a 600w Lumii Black ballast for a total of 960w, split into two 430w fixtures.

Option 4: Again, the Lumii Black2 720/960 can be split into 2 separate light fixtures. Power with one single 600w Lumii Black Ballast using the splitter cable for a total of 720w, split into two 360w fixtures.

A single ballast can be mounted on the 6-bar fixture, using brackets provided, but if the fixture is split and hung as 2 fixtures, or if 2 ballasts are used, they must be positioned remotely. The open construction of the fixture/s and the very low heat output assist airflow and heat management. Producing full spectrum light ideal for both growth and bloom, the Lumii Black² 720/960 LED will give impressive results.
