The materials that complement the production of our fixtures play an important role in the quality of our products, ensuring the highest standard fixtures in the hands of our consumers.
At Sylvania we have a wide range of ballasts; devices in charge of transforming energy in order to promote the appropriate fluorescent lamps operation. Depending on their structure, they are categorized as magnetic or electronic, or they may also be classified according to the type of lamp.
Ballasts functions are to:
A fluorescent lamp cannot be directly attached to a power cord since each fluorescent type needs starter voltages, which depends on the lamps length, diameter, construction and gases. Once the fluorescent has started, the ballast must regulate the electric current.
Ballasts are designed for four types of start options, according to the fluorescent lamp:
1. PH or Pre-Heat: These fluorescents require their electrodes to pre-heat before beginning the cycle and they need a starter.
2. QS or Quick Start: Like the previous one, this one needs its electrodes to pre-heat; nevertheless, the ballast is designed to heat the lamp without a starter.
3. RS or Rapid Start: They use low-voltage electrodes that are automatically pre-heated by the ballast, so they do not need a starter. The ballast has a heating coil that starts the lamp and keeps it running.
4. IS or Instant Start: This circuit lights the lamp by giving it a high-voltage discharge between the lamp electrodes, without the assistance of a starter.
These devices are placed in addition to the normal ballast fluorescent lamps, in order that at the time of failure of electricity supply, they’ll keep the lamp lit for an appropriate period of time to complete any work that could be in progress or to evacuate the place if necessary.
This type of ballast is more efficient than conventional ones since the design achieves fewer losses. These ballasts work with conventional or energy saving fluorescents.
Electronic ballasts use a completely different technology than the one used by the electromagnetic ballasts, since they use electronic components to start the lamp and regulate its operation.
Currently, new electronic ballasts are manufactured in high efficient designs that allow great benefits such as: longer life, energy saving, less maintenance costs, lower noise levels as well as temperatures and lighter components.
Ballasts for HID lamps must perform two very important roles:
Start: High voltage is applied to the lamps through the gases, starting a discharge and maintaining the voltage required to heat the lamp.
Control or Regulate: When the lamp starts, since it doesn’t have any filament that offers resistance, electric power can develop and cause an accident. Therefore, it is required to use the ballast as a controller in order to regulate and control electric power flow throughout the arch.
Parabolic diffusers represent the most sophisticated and highest optic precision control available for fluorescent fixtures. Its main characteristic is to redirect the generated light outside of the visual disconformity area of 60∞-90∞.
The role of the diffuser is to:
Strict light control is achieved thanks to the vertical shape of the diffusers walls, which work as small reflectors directing the light in a work area from 0∞to 45∞where it can be used more effectively. The nonexistence of light upon a 45∞angle eliminates unwanted reflections and provides an excellent visual effect.
Parabolic diffusers are available in specular and semi-specular finishes. Each one behaves differently according to the light intensity and source of brightness.
In general, darker diffusers are less efficient with a marginal V.C.P. (Visual Comfort Probability). The basic design of parabolic diffusers provides a superior V.C.P. through a sophisticated contour design.
Contact with grease and oils will stain the diffusers surface, stains that are highly visible and hard to get rid of. This will greatly affect the light distribution characteristics and the aesthetic part.
Therefore, diffusers should be handled wearing clean and dry gloves and never touched barehanded. They should be installed when the place is finished and not during construction or maintenance operations.

Opening Angle: horizontal angle where the diffuser projects no light.
V.C.P.: Visual Comfort Probability is an estimated level of visual comfort, averaged by 100 people in a room with a range of 0% (poor) and 100%(excellent).
Efficiency: quantity of light emitted from the fixture according to the light generated by the lamps.
Sylvania is recognized for its quality in all operations. We are constantly optimizing and innovating, seeking improvements in our products for the benefit of our customers.
The value and quality of our products are made up largely of the high quality raw materials we use. These are all the elements that transformed together become a unique product.
Raw materials with cutting edge technology suitable for the current market demands
Formulated based on polyester resin, which provides excellent protection against UV radiation, without yellowing or losing color even over time
Very good mechanical properties
Due to its characteristics, it guarantees a homogeneous and highly aesthetic finish
93% of reflectivity'
The materials reflect light according to characteristics such as texture and color. For example, surfaces with rough textures and dark colors absorb more light and therefore are less reflective than light smooth finish surfaces.
At Sylvania we know that the greater light output of the fixture depends on an appropriate selection of the reflector’s material, the diffuser, and the paint used in the manufacture of the fixture. High reflectivity paint can be used as part of the fixture’s reflector for its high capacity to redirect the light from the source into the work area. For the current lighting systems it is necessary to optimize resources, aesthetically and functionally, such as energy saving and environmental aspects. Among the benefits of using a product designed and manufactured by Feilo Sylvania with highly reflective paint are:
Higher light output per fixture, resulting in the use of fewer fixtures in the space
Higher levels of lighting in work areas, because each fixture produced by Sylvania is designed with the ability to give more light to the work area with highly reflective paint
Sylvania is investing in the continuous improvement of its products, to carry the maximum optimization of resources of all those products that our customers have available for the development of their projects under construction.
