E601C - Top class, 4-band, high intensity, fixed spectrum Heliospectra LED Grow Light

The Heliospectra E601C LED Grow Light is the result of a huge amount of research and development in the LED grow lighting field. After an extended period of testing and refinement, the Heliospectra E601C provides the grower with the ability to provide their plants with all the wavelengths of light that they need to grow vigorously and healthily. The E601C features the same LEDs that are used in it's more configurable brother, the LX601C, but without the ability to adjust the output of the 4 individual LED types. The Heliospectra E601C utilises 4 types of LED: 450nm (blue), 660nm (red), 735nm (far red) and finally a group of 5700K (White) LEDs to fill in the gaps in the spectrum to improve the structure and health of your plants.

Heliospectra E601C Spectrum Graph

The black line in the graph above represents the "McCree Curve", which gives a relative indication of how efficiently a plant uses the different colours in the light spectrum to photosynthesise with.

The Heliospectra E601C is the product of years of painstaking research in order to create the ultimate LED grow light. Grow lights have advanced a lot recently. Until quite recently, LED Grow lights tended to concentrate on producing just red and blue light which optimises the amount of chlorophyll photosynthesis that a plant performs. However, giving a plant just red and blue light has recently been shown to ultimately be to the plant's detriment. Plants grown with just red and blue light do not photosynthesise optimally, have poor structure and lack health and disease resistance. Plants need some light from most of the visible light spectrum in order to grow at their best.

For this reason, the Heliospectra E601C LED Grow Light utilises not only red and blue LEDs for high rates of photosynthesis but also the full spectrum light from white LEDs too. The white LEDs produces light at wavelengths which allow the plant to produce other compounds, such as carotenoids, which help to support the photosynthesis process so that the plant can fully utilise the blue and red light from the blue and red LEDs. Without these compounds, the plant cannot optimise the photosynthetic process. The other roles of the compounds produced by white light include good plant structure and much increased plant health. A healthy plant is more resistant to pests and diseases and has a better structure.

Far red light helps to optimise the flowering/fruiting response in plants, which is why the Heliospectra E601C grow light includes LEDs producing far red light. As it is not adjustable, the E601C produces less far red than the LX601C because this can cause stretching if used excessively in the first 2 weeks after the change in the photoperiod.

The Heliospectra E601C has a highly advanced lens which gives both an excellent spread of light while maintaining the intensity needed to optimise growth and yields.

How to Use the Heliospectra E601C:

Simply hang the Heliospectra E601C LED grow light in the centre of your grow space, preferably using a robust and adjustable product such as rope ratchet hangers. Heliospectra advise a height of about half a metre above the tops of your plants. Initially it may be advisable to start somewhat higher and lower it to half a metre over the course of a few days to gradually acclimatise your plants to the intensity. Connect the power lead into the mains and switch on.
