LUMii BLACK 2 720W/960W LED Grow Light

R9,580.00 Incl

This LED grow light fixture has a stunning operating efficacy of around 2.9 µmol/J, and is built using LED chips with individual efficacies of 3.4 – 3.7 µmol/J. Its maximum PPF output is an impressive 2596 µmol/s when powered at 960 W (by two ballasts each drawing 480 W). By comparison, a 1000W HPS lamp (drawing 1070 watts) will typically give an output of 1550 µmol/s PPF.

A very versatile, high-performing, high-efficiency mid-range LED fixture. Lightweight owing to not having an integral driver, it is easy to install. The fixture is made up of two interlocking halves, each having its own power input socket, and it can be hung either as a single interlocked 6-bar fixture or as 2 separate 3-bar fixtures. The 6-bar fixture is ideally suited to cover a growing area of 1.5m x 1.5m, whereas 2 separate 3-bar fixtures can cover a growing area up to 25% larger.

Whether hung separately or interlocked, the 2 half-fixtures can be powered by a single LUMii BLACK 600W Electronic Ballast using the splitter lead provided. Alternatively, each half fixture can be powered by its own LUMii BLACK 600W Electronic Ballast. Using 2 ballasts allows the maximum light output of the fixture/s to be increased by at least 25%.

A single ballast can be mounted on the 6-bar fixture, using the brackets provided, but if the fixture is hung as 3-bar 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. Note – Ballast/s not included.

Description

This LED fixture has a stunning operating efficacy of around 2.9 µmol/J, and has chip efficacies of 3.4 – 3.7 µmol/J. It gives an impressive 2596 µmol/s PPF when powered by 2 ballasts at 960 W total draw. To compare, a 1000W HPS lamp (drawing 1070 watts) will typically give 1550 µmol/s PPF.

A versatile, high-performing, efficient LED fixture, lightweight and easy to install. Being made as two interlocking halves, each with its own power socket, it can be hung as a single 6-bar fixture to cover a growing area of 1.5m² or as two 3-bar fixtures to cover a growing area up to 25% larger.

Whether separated or interlocked, the 2 half-fixtures can be powered by one LUMii BLACK 600W Electronic Ballast via the splitter lead. Alternatively, each half fixture can be powered by its own ballast. Using 2 ballasts increases the maximum light output of the fixture/s by ≈ 25%.

Technical Specifications:

• Full Spectrum LED
• Light output PPF:
• 1 ballast – 1870 µmol/s
• 2 ballasts – 2596µmol/s
• Maximum Chip Efficacy PPE – 3.7 µmol/J
• Optimum Output Efficacy PPE (at 100% / 600W ballast power setting) – 2.9 µmol/J
• AC Input power – Variable
• AV Input voltage – 130-160V
• AC Input Frequency – 40–100 kHz
• AC Current Maximum:
• One Ballast – 5 A
• Two Ballasts – 3.5 A (each)
• Max Power
• One Ballast – 720 W
• Two Ballasts – 960 W
• Lifetime – L90 >50,000Hr
• IP Rating – IP65
• 6 bar fixture – 110 cm x 105 cm x 4 cm
• 2 x 3 bar fixtures – 110 cm x 52.5 cm x 4 cm each

Should I hang my LUMii BLACK² 720/960 LED as a 6-bar fixture, or as two 3-bar fixtures? Which is best?

This depends upon your grow operation. If you’re growing in a 1.5m x 1.5m tent, then it would be best to hang it as a 6-bar fixture. If you have a large grow room, it would be better to set up an array of 3-bar fixtures hung no more than 50cm apart, to achieve maximum coverage. We recommend that you make a sketch plan of your growing area, and then find the most economical way to hang LUMii BLACK² 720/960 LEDs to light it.
Is it better to use one or two ballasts? What are the advantages and disadvantages?
This also depends upon your grow, and how you wish to manage it.

If you use two ballasts, obviously you get more light output, but you can only use 2 of the ballast’s power settings:

75% (400W) – which gives a light output PPF of 2596 µmol/s
• 50% (250W) – which gives a light output PPF of 1883 µmol/s
If you use only one ballast, you get a lower light output, but you can use all 4 of the ballast’s power settings, giving you more dimmability. The settings are:
• 115% Boost (600W Boost) – which gives a light output PPF of 2071 µmol/s
• 100% (600W) – which gives a light output PPF of 1883 µmol/s
• 75% (400W) – which gives a light output PPF of 1431 µmol/s
• 50% (250W) – which gives a light output PPF of 1073 µmol/s

To take maximum advantage of the fixture’s versatility, we recommend that you have two ballasts, but power the fixture using either one or two ballasts, dependent upon light output required.

At what height should I hang my LUMii BLACK² 720/960 LED?

We recommend that you should hang your fixture adjustably, using LUMii Rope Ratchets and that you set the fixture at around 30-50cm (minimum 15cm) above the canopy, adjusting the height as your plants grow. If, for your plants, the light is too intense and the plants show signs of stress, raise the fixture a little, or select a lower power setting on the ballast.
