Frequently Asked Questions - FAQ

What is color temperature?

Color temperature characterizes the impression of the color tone of light and is measured in Kelvins (K). The color of the light can be:

  • Warm white - 2700-3000K 3000K
  • Neutral light (or cool light) - 4000-4500K 4500K
  • Daylight - 6400-6500K 6400K

Warm white sources, such as incandescent lamps, have lower color temperatures in the range of 2700-3000K. Neutral light (4000-4500K) and daylight (6400K) have higher color temperatures.

What is luminous flux?

This is the light energy emitted from the light source in a given solid angle, depending on the distance. Measured in lumens (lm).

What is the light output?

It is the ratio of luminous flux and power consumption. Presented as lm/W.

To determine the efficiency of the light source, divide the number of lumens per watts, which he consumed. For example, a 60 watt lamp is about 840 lumens and therefore its efficiency is 14 lm/W.

What does color rendering index (CRI) mean?

Color rendering index is a measure of a light source's ability to show object colors "realistically" or "naturally". Can take values from 0 to 100.

VIVALUX® products are:

  • CRI > 80 – for light sources that are intended for indoor use.
  • CRI > 70 - LED spotlights whose use does not require very high precision color reproduction.

How many years warranty do you offer?

  • 12 months for all light sources: compact fluorescent lamps, LED lamps, discharge lamps;
  • 12 months for other products.

The period starts from the date of delivery of the product from the retailer in Bulgaria. Bringing a claim under commercial guarantee must be made no later than two months from the establishment of the inconsistency.

Exception to the 12-month warranty are products whose "natural" life is less than two years, such as light sources with life 1000-2000 hours or less.

VIVA does not provide commercial guarantee in case of damage caused deliberate change in the design of products, improper installation and improper use or storage, release, shock, moisture, wet (for products with a index of protection at least IP44), due to natural disasters and other external influences.

What lighting can I put in the bathroom?

When you choosing fixtures for the bathroom, make sure they are waterproof. Note the index of dust and moisture protection - IP. Rating IP (Ingress Protection) means 'Protection' and is always followed by two signs. The first one indicates dust protection. Starting with 0 for no protection, it reaches a maximum of 6, which is fully protected against dust.

  • 0 = No protection.
  • 1 = Protection against solids ≥ 50 mm diameter.
  • 2 = Protection against solids ≥ 12.5 mm diameter.
  • 3 = Protection against solids ≥ 2.5 mm diameter.
  • 4 = Protection against solids ≥ 1 mm diameter.
  • 5 = Protection against dust (limited ingress without damaging the product).
  • 6 = Complete protection against dust.

Мore interesting here is the second one sign, which means the degree of protection against ingress of moisture. It varies from 0 for no protection to 8 for a light source which can be fully immersed in water to a certain depth.

  • 0 = No protection.
  • 1 = Protection against vertically falling drops of water.
  • 2 = Protection against drops of water falling at an angle of 15° from the vertical.
  • 3 = Protection against falling water drops at an angle of 60° from the vertical.
  • 4 = Protection against splash water coming from all directions.
  • 5 = Protection against water jets.
  • 6 = Protection from strong jet.
  • 7 = Temporary immersion in water (-1 meter for 30 minutes)
  • 8 = Continuous immersion (depth of 1 m for a time specified by the manufacturer).

Bathroom fixtures VIVALUX® are with index of protection IP44 and IP65 and are suitable for installation in rooms with high humidity in the zones in the bathroom. Spotlights VIVALUX® are with IP44 to IP65 and are designed for outdoor use.

Your safety comes first

When choosing lighting for the bathroom, is necessary to consider whether the index of protection (IP) of the body is appropriate for the area where you plan to mount it. IP appears on the packaging of each model. Bathroom space as required for index of protection is divided into four zones.

Зони в банята

Which fixtures are suitable?

  • Zone 0. This is the area in the shower and in the tub, where the bodies were submerged. Fixtures must be with IP67, operating at voltages 12V.
  • Zone 1. Area, which is located above the zone 0 to a height of 2,25 m. Appliances must have a index of protection at least IP65 and are supplied with a voltage of 12V.
  • Zone 2. Located at least 0,60 m around and over Zone 1 and within a radius of 0,60 m around the sink. Here you can locate objects with IP44 and voltage 220V, as most bathroom fixtures VIVALUX® .
  • Zone 3. Rest of the room. There are no specific requirements for the index of protection. You can choose lighting with IP20.

Why do you recommend to use LED lamps?

The main reasons are that it will:

Save money

  • LED light sources use 90% less electricity than traditional. Users who switch to energy-saving light sources will pay less money for their monthly electricity bills for the same amount of light.
  • Further savings are achieved through long life LED lamps (from 25 000 to 50 000 hours).

Protect the environment

  • LED lights consume less electricity, so lighting will require less non-renewable natural resources and will emit fewer emissions. In fact this is the biggest advantage of LED lights for the environment.
  • LEDs are extremely durable and do not contain hazardous substances above permissible for electronic and electrical equipment. These facts make it safer for use in the variant relative to the other light sources.

Is it true that luminous flux of LED lights decrease over time?

LED lights have a much longer life than incandescent lamps. During servicing of LED lamps their light flow gradually decreases. It is assumed that when it dropped by 30% from the original, LED lamp has reached the end of its life. This is after 25 000 to 50 000 hours of operation.

What should I do if I break energy saving lamp?

Clean up broken glass with gloves to prevent skin from getting cut by glass. Do not use a vacuum cleaner. Ventilate the room and wash your hands thoroughly. The remains of energy saving lamp, because the mercury content, can not be disposed of as normal household waste.

In the production of energy saving lamps VIVALUX® is used amalgam - it is an alloy of mercury with other metals. In the form of the mercury amalgam is located in a stable solid form at room temperature. The amalgam is more ecological alternative to liquid mercury as mercury vapor is not released until reaching the ambient temperature 100 ° C. All energy-saving VIVALUX® lamps are made by "amalgam technology" and are absolutely safe during the use.

VIVA participate in a collective system for the performance of its obligations under the Law on Waste Management Act (WMA) for separate collection, reuse, recycling and recovery of end-of-life lamps, fluorescent lamps and luminaries like and encourages users to back defective and obsolete products or have them disposed of in designated containers for discarded electronic and electrical equipment (WEEE).

Information points for WEEE recycling can be obtained by RIEWs across the country, local authority or local waste collection service for household waste disposal.

Despite the efforts that we at VIVA and other companies are making towards lighting collection, recycling and recovery of WEEE, the main and most important role in this process play consumers. By its decision to comply with the recommendations for separate collection of this waste, they contribute to:

  • prevent the negative environmental impact of WEEE;
  • increase the amount of reused, recycled and recovered by other WEEE operations, which contribute to the efficient use of natural resources;
  • measures taken by those involved in the eco-design to limit the impact of energy-saving lamps throughout their life cycle and formed their waste on human health and the environment.

Improper collection or treatment of waste from EEE in the environment may liberate hazardous substances and is likely to pose a risk to human health or the environment.

Improper collection or treatment

The symbol indicating separate collection for EEE consists of the crossed-out wheeled bin. This symbol is placed on any product that is electronic and electrical equipment within the meaning of Directive 2012/19/ES of the European Parliament and the Council. After exiting from the use of this product, it should not be disposed of with household waste.

Is it true that halogen lights sources are more effective compared to traditional incandescent bulbs?

Yes, halogen lamps of Class C are up to 30% more efficient than traditional incandescent lamps. If you need to buy a certain type of halogen bulb, choose one that is the most energy efficient, from higher energy efficiency class. You'll save energy and money by replacing halogen bulbs with LED or energy saving lamps.

What color temperatures of halogen lamps do you offer?

Halogen light is very similar to natural sunlight. Halogen light sources of VIVALUX® lamps are available in warm white light - 2800K and a color rendering index of 100, in which the human eye perceives as comfortable colors.
