The Spectrabox Gold-4S Edition is an advanced LED grow light. It is equipped with the latest LED technology, like SSP, SPC and high luminous 3W CREE led chips. Also the LED spectrum can be adjusted by a Spectrum Control System, which enables to adjust the light output of the grow- and flowering sections separately. This tuning devices make it possible to create an ideal growing and flowering environment to maximize yield. The Spectrabox Gold-4S Edition is available in 260W, 400W and 520W and comes with a yellow-gold colored frame.

Spectrum Control System:
With two Spectrum Controllers on the front side of the Spectrabox Gold, the output of the light spectrum for growing and flowering can separately be adjusted.

During early growing stage only the Spectrum Controller for the blue grow sections needs adjustment. The Spectrum Controller for the is flowering section can be switched off. For seedlings and cuttings start with a light output of about 30% and slowly raise the light output during the growing stage. For 100% light output the plants need to be completely settled. In the last week of growing, the Controller for the flowering section can be slowly set to 50%. In the growing stage the distance between the light and the plants can be about 25 to 35cm, depending on the lighting area and model Gold Edition.

During flowering stage both Spectrum Controllers needs adjustment. The Controller for the growing section needs to start at 100% and can be slowly adjusted to about 70% in the last two weeks. The Controller for the flowering section can start at about 50% and slowly go to the full 100% in about a week time. The distance between the light and the plants can be about 25 to 35cm, depending on the lighting area and model Gold Edition.

For maximum yield, it's better to use more pieces of "small" LED grow lights then one big LED light. By small we mean LED grow lights with a LED value till 600W, in stead of the more powerful LED grow lights. For example; use 3 pieces 400W Spectrabox Gold units on (3 x 0.5 =) 1.5 m2 in stat of one piece 1200W on the same 1.5 m2. Firstly the light intensity is more equally spread over the area, secondly the 3 pieces 400W can lighten a larger area then 1 piece 1200W and thirdly the yield will increase!

LED Drivers
The Spectrabox Gold-4S Edition is provided with high-tech Japanese LED drivers. These high quality drivers do drive the high power 3W CREE LED chips at a low Amperage of only 650 mA. At 650 mA the 3W LED chips do have a maximum light efficiency and an extreme long life span, while only losing about 25% of the light output in 30.000 hours.
