The technical data sheet for FINOM
- Shades: birch craft plywood (colors natural, black and white)
- Floor lamp legs: waxed ash with chrome plated steel screws
- Electric wires: fabric-coated electric wire (selection of different colors)
- Designed in Finland by Pure Design Oy and produced by Innoite Oy
Materials and other details:
FINOM uses only 100% PEFC Certified plywood. The material comes from a small selected non-industrial and family owned forest in Finland. FINOM plywood is extremely thin (0,4 mm) and consists of three turned layers of Finnish birch. What make the FINOM plywood special and unique is that it can be produced only from the slow-growing Finnish birch logs during low-temperature winter time.

FINOM lights use only LED bulbs (Light-Emitting Diode) that are low-energy class A++, A+ or A (EU Directive 2010/30/EU). One of the design features of the FINOM series is to provide elegant and peaceful light to the sides as well as good working light downwards. This is why we recommend to use “cool light”, i.e. a color temperature of 4000 K (Kelvin-value). Because of the transparency of the shades, we recommended the use of LED bulbs with quite a high Light-value (Lumen-value) of 1050 lm to 1520 lm (corresponding 10 watt to 13 watt power consumption). The color rendering capability (RA-index) for FINOM products is over RA80.
Typical FINOM LED features are: Instant full light, switch on/off 1 000 000 times, last for 25 000 hours. Read more about the LED bulb features here.
Standard LED bulb for FINOM is E27 (Europe, Edison Screw ES-type), but that can be adjusted on separate request according to local needs. FINOM Pendant lights are normally delivered with wire connectors (type WAGO) to enable simple and fast installation of the lights (country based standards can be requested separately). FINOM Floor lights are normally delivered with foot-switch (optionally dimmer-switch) and SUKO-type (type E/F) plug & sockets (US Department of Commerce International Trade Administration ITA), but other types of plugs & sockets can be requested separately according to local country based standards. FINOM lights belong to Protection class 1 (IEC protection classes defined in IEC 61140) and IP Code 20 (IP Code, International Protection Marking, IEC standard 60529).

FINOM light uses LED bulbs (Light-Emitting Diode) that are low-energy class A++, A+ or A (EU Directive 2010/30/EU). The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes from A to G on the label, A being the most energy efficient, G the least efficient. The labels also give other useful information to the customer as they choose between various models. (Source: en.wikipedia.org/wiki/European_Union_energy_label).
Note: FINOM lights use only LED bulbs, other than LED bulbs cannot be used because of the generated warmth that will cause ageing of the plywood material!
Color temperature (CCT) of the recommended FINOM light bulbs is 4000 K (Kelvin-value).
The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e., those on a line from reddish/orange via yellow and more or less white to blueish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light. Color temperature is conventionally expressed in kelvin, using the symbol K, a unit of measure for absolute temperature.
Color temperatures over 5000 K are called “cool colors” (bluish white), while lower color temperatures (2700–3000 K) are called “warm colors” (yellowish white through red). “Warm” in this context is an analogy to radiated heat flux of traditional incandescent lighting rather than temperature. The spectral peak of warm-coloured light is closer to infrared, and most natural warm-coloured light sources emit significant infrared radiation. The fact that “warm” lighting in this sense actually has a “cooler” color temperature often leads to confusion.
For lighting building interiors, it is often important to take into account the color temperature of illumination. A warmer (i.e., a lower color temperature) light is often used in public areas to promote relaxation, while a cooler (higher color temperature) light is used to enhance concentration, for example in schools and offices. (Source: en.wikipedia.org/wiki/Color_temperature).
The light-value of the recommended FINOM lights LED bulbs is between 1050 lm to 1520 lm (corresponding to 12 watt to 16 watt power consumption).
The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a “luminosity function”) of the human eye’s sensitivity to various wavelengths. Lumens are related to lux in that one lux is one lumen per square meter.
On September 1, 2010, European Union legislation came into force mandating that lighting equipment must be labelled primarily in terms of luminous flux (lm), instead of electric power (W). This change is a result of the EU’s Eco-design Directive for Energy-using Products (EuP). For example, according to the European Union standard, an energy-efficient bulb that claims to be the equivalent of a 60 W tungsten bulb must have a minimum light output of 700–750 lm. (Source: en.wikipedia.org/wiki/Lumen_(unit)).
Note: According to above data, FINOM 1050 lm/12 watt corresponds to the old 75W tungsten bulb and 10520 lm/16 watt corresponds to the old 100W tungsten bulb.
Luminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt in the International System of Units (SI). Depending on context, the power can be either the radiant flux of the source’s output, or it can be the total power (electric power, chemical energy, or others) consumed by the source. Which sense of the term is intended must usually be inferred from the context, and is sometimes unclear. The former sense is sometimes called luminous efficacy of radiation, and the latter luminous efficacy of a source or overall luminous efficacy. (Source: en.wikipedia.org/wiki/Luminous_efficacy#Lighting_efficiency).
Color rendering capability (CRI or RA index) for FINOM LED bulbs is > RA80
A color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source. Light sources with a high CRI are desirable in color-critical applications such as neonatal care and art restoration. It is defined by the International Commission on Illumination (CIE) as follows: Color rendering, effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant.
The CRI of a light source does not indicate the apparent color of the light source; that information is given by the correlated color temperature (CCT). The CRI is determined by the light source’s spectrum. The value often quoted as “CRI” on commercially available lighting products is properly called the CIE Ra value, “CRI” being a general term and CIE Ra being the international standard color rendering index.
Numerically, the highest possible CIE Ra value is 100 and would only be given to a source identical to standardized daylight or a black body (incandescent lamps are effectively black bodies), dropping to negative values for some light sources. Low-pressure sodium lighting has negative CRI; fluorescent lights range from about 50 for the basic types, up to about 98 for the best multi-phosphor type. Typical LEDs have about 80+ CRI, while some manufacturers claim that their LEDs have achieved up to 98 CRI.
CIE Ra’s ability to predict color appearance has been criticized in favor of measures based on color appearance models, such as CIECAM02 and for daylight simulators, the CIE Metamerism Index. CRI is not a good indicator for use in visual assessment, especially for sources below 5000 kelvin (K). A newer version of the CRI, R96, has been developed, but it has not replaced the better-known Ra general color rendering index. (Source: en.wikipedia.org/wiki/Color_rendering_index)
Standard LED bulbs for FINOM is E27 (Europe, Edison Screw ES-type), but that can be adjusted for local needs by separate request.
Edison screw (ES) is a standard socket for light bulbs in North America. It was developed by Thomas Edison and was licensed in 1909 under General Electric’s Mazda trademark. Normally, the bulbs have right-hand threaded metal bases (caps) which screw into matching threaded sockets (lamp holders). For bulbs powered by AC current, the thread is connected to neutral and the contact on the bottom tip of the base is connected to the “hot” phase.
In North America and continental Europe, Edison screws displaced other socket types for general lighting. In the early days of electrification, Edison screws were the only standard connector, and appliances other than light bulbs were connected to AC power via lamp sockets. Today Edison screw sockets comply with international standards. In the designation “Exx”, “E” stands for “Edison” and “xx” indicates the diameter in millimeters as measured across the peaks of the thread on the base (male), e.g., E12 has a diameter of 12 mm. This is distinct from the glass envelope (bulb) diameter, which in the U.S. is given in eighths of an inch, e.g., A19, MR16, T12.
There are four commonly used thread size groups for mains supply lamps:
- Candelabra: E12 North America, E11 in Europe
- Intermediate: E17 North America, E14 (Small ES, SES) in Europe
- Medium or standard: E26 (MES) in North America, E27 (ES) in Europe
- Mogul: E39 North America, E40 (Goliath ES) in Europe.
The E26 and E27 are usually mechanically interchangeable, as are the E39 and E40, because their screw threads are similar enough in dimension. In countries that use 220–240 volts AC domestic power, standard-size E27 and small E14 are the most common screw-mount sizes and are prevalent throughout continental Europe and China. In 120-volt North America, 100-volt Japan and Taiwan, the standard size for general-purpose lamps is E26. (Source: en.wikipedia.org/wiki/Edison_screw).
Wired Connetors for Pendant
FINOM Pendant lights are delivered with so called WAGO wired connectors (www.wago.com) to the sealing wires to enable simple and fast installation of the lights (country based standards can be requested separately).
In Finland, country based options have been developed for modern housing and sealing sockets or light plugs (three different models). Other than wired connector type of solutions include three models called protective earth plug (picture 1), class 0 plug (picture 2) and crown coupling plug (picture 3).
However, as a producer FINOM lights are in the situation that we need both solutions (a light plug and wired connectors on wires) and we need customers to indicate if they need something other than wired connector type of solutions while ordering the products, so we can ensure the right solution for the customer.
Connectors for Floor Lights
FINOM Floor lights are normally delivered with foot-switch (optionally dimmer-switch) and SUKO-type (type E/F) plug & sockets (US Department of Commerce International Trade Administration ITA), but other types of plugs & sockets can be requested separately according to local country based standards.
Type F (picture 2) is used, for instance, in Germany, Austria, the Netherlands, Sweden, Finland, Norway, Portugal, Spain and Eastern Europe. Plug F is known as CEE 7/4 and commonly called “Schuko plug”, which is the acronym of “Schutzkontakt”, a German word meaning “protection contact” or “safety contact”. The plug was designed in Germany shortly after the First World War. It goes back to a patent (DE 370538) granted in 1926 to Albert Büttner, a Bavarian manufacturer of electrical accessories.
Because the CEE 7/4 plug can be inserted in either direction into the receptacle, the Schuko connection system is unpolarised (i.e. line and neutral are connected at random). It is used in applications up to 16 amps. Above that, equipment must either be wired permanently to the mains or connected via another higher power connector such as the IEC 60309 system.
Type F: 2 pins, grounded, 16 A, 220 – 240 V, socket compatible with plug types C, E & F
In order to bridge the differences between sockets E and F, the CEE 7/7 plug was developed. This plug, which is shown above, has earthing clips on both sides to mate with the type F socket and a female contact to accept the earth pin of the type E socket. The original type F plug, which does not have this female contact, is now obsolete, but a rewireable version may still be available at some DIY shops.
Type E (picture 1) is primarily used in France, Belgium, Poland, Slovakia, the Czech Republic, Tunisia and Morocco a socket which is different from the CEE 7/4 socket (type F) that is standard in Germany and other continental European countries. The reason for incompatibility is that grounding in the E socket is accomplished with a round male pin, which is permanently mounted in the socket.
Type E: 2 pins, grounded, 16 A, 220 – 240 V, socket compatible with plug types C, E & F
In order to bridge the differences between sockets E and F, the CEE 7/7 plug was developed: it has grounding clips on both sides to mate with the type F socket and a female contact to accept the grounding pin of the type E socket. Note that the CEE 7/7 plug is polarised when used with a type E outlet. The plug is rated at 16 amps. (Source: www.worldstandards.eu/electricity/plugs-and-sockets/).
FINOM lights are Protection class 1 (IEC protection classes defined in IEC 61140)
In the electrical appliance manufacturing industry, the following IEC protection classes are defined in IEC 61140 and used to differentiate between the protective-earth connection requirements of devices. These appliances must have their chassis connected to electrical earth.
These appliances must have their chassis connected to electrical earth (US: ground) by a separate earth conductor (coloured green/yellow in most countries, green in the US, Canada and Japan). The earth connection is achieved with a 3-conductor mains cable, typically ending with 3-prong AC connector which plugs into a corresponding AC outlet. A fault in the appliance which causes a live conductor to contact the casing will cause a current to flow in the earth conductor. If large enough, this current will trip an over-current device (fuse or circuit breaker (CB)) and disconnect the supply. (Source: en.wikipedia.org/wiki/Appliance_classes).
IP Code Class
FINOM light belongs to IP Code class IP20 (IP Code, International Protection Marking, IEC standard 60529).
The IP Code, International Protection Marking, IEC standard 60529, sometimes interpreted as Ingress Protection Marking, classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The equivalent European standard is EN 60529.
IP indication is normally expressed with two numbers. First digit indicates solid particle protection and second digit indicates liquid ingress protection.The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects. The second digit indicates the level of protection that the enclosure provides against harmful ingress of water.
IP 20 means that the product is effective against objects bigger than 12,5 mm (e.g. a finger) and that it has no protection against any liquid or dripping water. (Source: en.wikipedia.org/wiki/IP_Code).
