            Discover the value of high-performance LED grow lighting with the LUMii Black 720W LED 6-Bar Fixture. This superb full-spectrum LED is supplied as a complete kit with the versatile LUMii Black 600W Digital Ballast, offering a powerful and affordable solution for professional UK indoor gardening and hydroponics. Delivering an impressive 1870 µmol/s PPF and high efficacy of 2.6 µmol/W, this fixture surpasses standard 1000W HPS lamps in output and energy efficiency. Its 6-bar design ensures superior, uniform light spread across the plant canopy, perfectly covering a 1.5 m x 1.5 m area while significantly simplifying grow room heat management. Get optimal results from propagation through to full bloom. Key Benefits of the LUMii Black 720W LED 6-Bar Fixture- Exceptional Value & Output: Delivers a potent 1870 µmol/s PPF, exceeding the output of typical 1000W HPS systems, all at a competitive price point.
- High Energy Efficiency: Achieves an excellent efficacy of 2.6 µmol/W, reducing operational costs for your indoor grow compared to HID lighting.
- Full Spectrum Power: Features full spectrum plus 660 nm diodes, providing the ideal light quality necessary to support all stages of plant life, from vegetative growth to heavy flowering.
- Superior Light Uniformity: The 6-bar design ensures a much more even distribution of light across the entire plant canopy than traditional reflectors, drastically reducing the risk of scorching and hot spots.
- Integrated Dimmability: Powered and controlled by the included LUMii Black 600W Electronic Ballast, allowing you to dim the light to 400W or 250W, or utilise the 600W Boost setting for maximum light.
 How to Use the LUMii Black 720W LED 6-Bar Fixture- Assembly & Connection: The LUMii Black 720W LED 6-Bar Fixture is designed to be powered directly by the LUMii Black 600W Electronic Ballast (included).
- Ballast Mounting (Two Options):
 - Direct Mount (Simpler): The ballast can be fitted directly onto the top of the LED fixture using the brackets and fixings supplied. This is simple but adds the ballast's heat to the grow environment.
 - Remote Placement (Better Heat Management): For optimal temperature control, the ballast can be positioned remotely (up to 10 metres away) from the fixture. This requires a LUMii Extension/Link Lead (sold separately).
- Hanging Height: Use adjustable hangers, such as Rope Ratchets (sold separately), to hang the fixture. Set the height at approximately 30-50 cm (minimum 15 cm) above the plant canopy. Adjust the height or use a lower power setting on the ballast if signs of light stress appear.
- Power Control: Utilise the dimmable settings on the LUMii Black Ballast (250W, 400W, 600W, and 600W Boost) to perfectly match the light intensity to your plants' specific growth stages.
 Frequently Asked QuestionsCan I use a different ballast with the LUMii Black 720W LED Fixture?No, the LUMii Black 720W LED 6-Bar Fixture is specifically designed to be powered and controlled only by the LUMii Black 600W Electronic Ballast (which is included in this kit), using its proprietary connection system.How does this LED compare to a 1000W HPS grow light?The LUMii Black 720W LED delivers 1870 µmol/s PPF at 720W, which is superior to the light output of a standard 1000W HPS lamp (typically around 1550 µmol/s). The LED also produces less heat, has a longer lifespan, and provides a much more uniform light spread.What is the optimal coverage area for this fixture?This 6-bar LED fixture is ideally suited to cover a growing area of 1.5 metres by 1.5 metres, ensuring every plant within that footprint receives consistent, high-quality light for maximum growth and bloom.Is it necessary to position the ballast remotely, or can I mount it on the fixture?You have both options. Mounting the ballast directly is simpler. However, positioning the ballast remotely (outside the grow tent) using a LUMii Extension/Link Lead is highly recommended as it significantly improves grow room temperature control by removing the ballast's heat source from the growing environment.SKU: 1514
