Featuring an impressive build quality & low introductory price, with the hot summer months approaching, now’s the time to replace hot inefficient HPS lighting & make the switch to LED. These LED fixtures exceed the performance of a typical 1000W HPS lamp & get close to the output of a double ended 1000W lamp (PPF rating: 1870 µmol/s).

Lumii Black LED frequently asked questions:
Q: Why should I choose LED lighting rather than HID lighting?
A: The advantages of LED are clear. There is little heat output from LED lights, and so heat management is much simpler. Also, the power consumed relative to the light output is far less with an LED fixture than with a HID lamp. With some types of LED light, the spectrum is adjustable to suit either grow or bloom, which is never the case with HID lamps. Other types of LED, such as this LUMii BLACK fixture, give full spectrum light suited to both grow and bloom stages, which is not always the case with HID lamps. An LED Fixture gives a much more even spread of light across the canopy, whereas HID lighting must be reflected from a narrow central source – the lamp.
Q: At what height should I hang my LUMii BLACK LED Fixture?
A: 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.
Q: Where should I place the LUMii BLACK 600W Electronic Ballast to power the LED Fixture?
A: There are 2 options:
1.The Ballast may be fitted to the LED Fixture using the brackets and fixings supplied.2.The Ballast may be positioned remotely (up to 10M away) from the LED Fixture using an LUMii Extension/ Link Lead. Option 1 is simpler and requires no extra components. However, the heat emitted by the ballast will tend to contribute to the ambient temperature of the growing environment during the light / growing period of the day.
Option 2 requires the purchase of LUMii Extension/ Link Leads (refer to fixture instructions to select these), but if the ballast is positioned remotely then the heat management of the growing environment is easier, and the Ballast and LED Fixture can be controlled without entry to or disturbance of the grow room.
