With an amazing ability to deliver more lumens to your plants than most other light systems and an equally impressive low requirement for energy, how can you possibly ignore the sensational E-Papillon? Anyone aiming to achieve truly incredible results whilst at the same time avoiding having to pay through the roof for it will find there’s an awful lot to get excited about here!
The Philips GreenVision ballast was created by the company to get the most out of the 600 Watt Philips GreenPower lamp and certainly does excel at the job intended.
Being positioned directly behind the reflector enables the ballast to connect to the lampholder without needing a lengthy cable, helping prevent electromagnetic interference for an uninterrupted supply of energy to the light. When you consider that the lamp already utilises a design geared towards electronic ballasts and is also a high quality dual spectrum model built to run the entire length of a crop, you clearly have a winning combination!
Of course the E-Papillon reflector proves to be as equally important as the aforementioned components, delivering a broad beam of diffused light that penetrates deep into the plant canopy.
The open-ended nature of the product ensures there is a natural airflow in and around the lamp area, which helps disperse heat and stops hot spots from occurring above plants.
This concerted effort to keep temperatures down not only works wonders for extending the life span of the E-Papillon, it actually lets you reduce the distance between the reflector and plant tops to an absolute minimum.
In terms of maintenance, an intelligently constructed lampholder makes for safe and easy bulb changes and the reflector wings conveniently slide out of the unit for cleaning and replacement if necessary.
Pivotal to the success of the E-Papillon is the fantastic Philips technology residing inside both the ballast and lamp, which plays a significant role in making them super efficient, longer lasting products that by far and away out perform those of its competitors.
Quite incredibly, selecting this light system will actually save you around 5% on your electricity bill compared to using alternative options!
Also comes with an 8 mtr power cable
Light and plants
Plants have a different sensitivity response than humans to light of various wavelengths. For green plants, the sensitivity to red light is highest and it is lowest for green light. For this reason, the ‘lux’ unit is not the right measure for the lighting of green plants. Light sources may be regarded as sources of energy particles; these are called light quanta or photons. Most lighting products are developed for applications with human beings at centrestage. The units ‘lumen’ and ‘lux’ are relevant for these. The unit lux has its origins in photometry and is based on the average sensitivity of the human eye. The maximum sensitivity is around 555 nm (yellow-green light) and reduces in case of longer (red) and shorter (blue) wavelengths.
All photons, from blue to red (400 to 700 nm), are used for photosynthesis, but this does not happen for every photon with the same output. This is termed the ‘plant sensitivity graph’.
Micromol (µmol): Since the end of 2004, Philips has been supplying its lamps with specifications in µmol. All guarantees are also issued with µmol values. Studies carried out by universities and testing stations show that the speed of growth of plants is mainly determined by the number of photons between 400 and 700 nm that they absorb. The growth light is indicated by the abbreviation PAR, and is the only reliable measure to indicate whether a lamp is suitable for photosynthesis. The higher the PAR value per Watt, the more efficient the lamp. For this reason, Philips specifies the PAR value for all its ‘growth lamps’, expressed in micromol photons per second (µmol/s).
Photosynthesis is a photochemical process in which growth light is absorbed by the chlorophyll and carotenoids of leaves. The cultivation light absorbed is used in the form of light energy for the formation of sugars from carbon-dioxide (CO2) which is absorbed through the leaves. This process may be represented in the following manner:
6 CO2 + 6 H2O + lichtenergie -> C6H12O6 + 6 O2
carbon dioxide + water + light energy gives sugar + oxygen
Growth light is an important production factor in many plants. Growth light drives photosynthesis, due to which assimilates become available for growth and related development of the plant. Photosynthesis and growth are like the two pans of a balancing scale that must be in balance in order to achieve optimum production. Photosynthesis is controlled by the quantity of available growth light, and growth is controlled by the quality of light and temperature. When investing in assimilation lighting, attention should not only be paid to the quantity of added growth light, but also to the quality of the light and the temperature effects of the installation on the plant.
