Frequently asked questions

Our manufactured luminaires are offered in various designs, specifically:

Surface-mounted luminaires (no special marking, e.g., AURA 2) – Luminaires that can be mounted on ceilings and also on walls (unless otherwise specified on the product page). The installation is surface-mounted.

Semi-recessed luminaires (marked with V, e.g., AURA V2) – Luminaires that can be mounted on ceilings and also on walls (unless otherwise specified on the product page). Installation is carried out into pre-prepared openings in the ceiling/wall matching the size of the luminaire’s base. The luminaire is then fixed into this opening using special brackets. Compared to surface-mounted luminaires, semi-recessed luminaires are visually more elegant (only the diffuser is visible), but their installation should be carefully planned in advance.

Suspended luminaires (various markings, e.g., ADRIA S2) – Luminaires mounted on ceilings. Installation is surface-mounted. These luminaires are available in a wider range of designs. For more information, see the FAQ section How to understand different types of suspended luminaires.

Industrial luminaires (no special marking, e.g., TRITON 2) – Luminaires that can be mounted on ceilings and walls (unless otherwise specified). Installation is surface-mounted. These are characterized by higher durability and a design suitable for outdoor areas, garages, basements, etc.

Table lamps (no special marking, e.g., BIANCA 2) – Luminaires that can be freely placed without installation. They include a power cable with a switch.

Our suspended luminaires are available with various suspension types:

P (e.g., ADRIA P) – Rod suspension, available in lengths from 20 to 100 cm.

L (e.g., ADRIA L) – Suspension made of stainless steel cables with a supply cable, standard length 100 cm (can be shortened).

LE (e.g., CARINA LE) – Suspension made of steel cables without a supply cable (low voltage on wires – SELV), standard length 100 cm (can be shortened).

S (e.g., ADRIA S) – Suspension made of a cable with an internal steel support wire, standard length 100 cm (can be shortened).

ST (e.g., ZETA ST) – Suspension made of a textile braided cable with an internal steel support wire, standard length 100 cm.

R (e.g., MIRA R) – Suspension made of a chain with large links and a supply cable.

Our luminaires are available with glass or plastic diffusers:

Glass diffusers – TRIPLEX OPAL – Hand-blown, special three-layer glass (crystal–opal–crystal) with a matte surface. These diffusers have exceptional appearance and optical qualities. Due to triple light refraction, they prevent glare even with high-power light sources. Hand-blown glass makes these diffusers a stylish design element for both indoor and outdoor use.

Plastic diffusers – PC, PMMA, PE – An alternative to glass, available in materials such as opal polycarbonate (PC), opal PMMA, and polyethylene. All plastics are high-quality with UV stabilization to prevent aging (yellowing). Plastic diffusers are more resistant to mechanical damage; for PC, IK10 is standard. These are suitable where glass cannot be used, especially for safety and durability reasons.

We manufacture our luminaires in two basic versions: the bulb version and the LED version. A more comprehensive overview of the advantages of both versions can be found in the table below:

Classic on/off – Standard switching on/off.

Sensor – Controlled by a high-frequency motion sensor; turns on when motion is detected, then switches off after a set time. Adjustable in the luminaire.

Dimmable – Equipped with a DALI dimmable driver. Allows grouping and brightness control via a DALI system or manually (requires 4- or 5-core wiring).

Emergency – Works only in emergency mode during power failure for a set time (e.g., 1h or 3h).

Combined emergency – Works as a regular on/off luminaire, switches to emergency mode during outages (3h standard, other durations on request).

Combined emergency + sensor – Same as above, with motion sensor control.

Combined emergency SELFTEST – Same as combined emergency but with automatic self-testing.

Combined emergency SELFTEST + sensor – Same as combined emergency with sensor but with automatic self-testing.

Corridor - Corridor function (DALI + sensor) – Adjusts brightness based on motion (e.g., 10% standby, 100% with motion detected).

Tunable White – Adjustable color temperature (2700–6500K) via DALI, Bluetooth, Smarthome etc.

Yes. We offer custom production, including non-standard emergency modules, drivers, control systems, different CCT (1800–6500K), or CRI (>90, >95). Often available from 1 piece.

If you are interested in non-standard equipment, please send your request to the email address osmont@osmont.cz.

Can I request a different luminaire color or suspension length?

Yes. We can adjust base color, glass finish (matte/glossy), or suspension length for most models.

If you are interested in custom solutions, please send your request to the email address osmont@osmont.cz.

OTHER USED ICONS/PICTOGRAMS




The colour rendering index CRI80 is the standard for OSMONT luminaires. On request, we often also offer a colour rendering index of CRI>90 or CRI>95. If needed or interested, please contact us at osmont@osmont.cz.



The CE marking indicates that the product has been assessed before being placed on the market and meets the legislative requirements of the EU – meaning the manufacturer has verified or had verified by a notified body that the product meets all applicable essential requirements for safety, health protection, environmental protection, etc.



The UKCA marking is the equivalent of the CE marking for the UK market (Great Britain). It is a declaration proving conformity with British legislation.



Luminaire suitable for power supply of 230V and 50Hz. For any questions, please contact osmont@osmont.cz.



The luminaire is equipped with a DALI (Digital Addressable Lighting Interface) dimmable driver. If you have a DALI control system, you can create groups of luminaires and switch or dim them as needed.



The luminaire is equipped with a DALI dimmable driver and also a Bluetooth wireless module from TRIDONIC (Cassambi), enabling control via a mobile application or a special remote control.



The luminaire is equipped with a high-frequency motion sensor (HF). For selected luminaires (DELIA, TITAN), it is also possible to alternatively fit a PIR radar motion sensor.



Svítidlo je vybaveno nouzovým nebo nouzovým kombinovaným modulem. Nouzový modul umožňuje funkčnost pouze nouzového režimu. Nouzový kombinovaný modul umožňuje funkci klasického svítidla, pouze v případě výpadku přepne na nouzový režim. Standardně nabízeno s časem 3h, u některých typů 1h. V případě jiného požadavku kontaktujte osmont@osmont.cz.



The luminaire is equipped with the so-called CORRIDOR function. This function combines a DALI driver and an HF motion sensor. The CORRIDOR function enables changes in light intensity depending on movement in the given space. A 10-100% setting means that in the absence of movement, the luminaire lights at only 10%, and when motion is detected, it lights at 100%, then dims back to 10% once movement stops.



The luminaire is equipped with a Tunable White system, allowing the user to set the colour temperature as needed in the range from 2700K to 6500K. The TW luminaire is controlled via a DALI driver or a wireless Bluetooth module. In addition to adjusting the colour temperature, it is also possible to change the light intensity.
