The making of the Secto Design lamps requires preciseness and material knowledge.

Hand-made in Finland

Secto Design shades are made of certified, top-quality birch veneer that is form pressed into blanks. The blanks are cut into slats, which are sanded and finally connected using rings of thin plywood. The slats are glued and nailed to the rings. All Secto Design lamps undergo a thorough quality inspection before they are sent to their final destination.

The finishing options for the shades are untreated natural birch, white or black laminate or waxed walnut veneer. Other colours can be customised for projects at extra cost. The light distribution curves of the Secto Design lamps as well as further information on particular models can be found on the product pages.

Most Secto Design lamps use LED bulbs as a light source.

LED bulbs

The majority of Secto Design lamps use LED bulbs as a light source. The recommended color temperature is pure white, 3000 K (daylight being 4000 K). For security reasons at least 15 mm space should be left between the bulb and the shade to allow air to circulate. If a dimmer is used, please check the compatibility of the dimmer with the light source. The use of special bulbs such as halogen, mirror or 12 V is forbidden due to overheating. 

In Europe all the lamps are delivered with a light source: either a suitable bulb or a built-in LED. The bulb is an example of a suitable light source for the model in question. There might be variation in the bulbs due to supply. The guarantee of the lamps does not cover the example bulbs.

Built-in LED

The built-in LEDs are included worldwide in the Owalo, Aspiro, Atto and Kuulto lamps. The current life span estimation of LED is approximately 15 000 hours. 

The Secto Design LED lamps use high-quality LEDs. Secto Design reserves the right to replace the current LED components to similar or better ones due to the rapid development of LEDs and changes in supply. 

It is recommended to use dimmers optimized for built-in LEDs. The cable and the built-in LEDs can only be replaced by the manufacturer.

The cable set used with Secto Design pendant lamps.

The cable set by Dezall is especially customised for Secto Design.


The colour of the cable depends on the lamp model and the colour of the shade. The standard cable colours are listed in the product information of each model. 

A ceiling cup, designed by Secto Design using the patented suspension system by Dezall, and a connector are included in the cable set of the pendant lamps. The Magnum and Owalo pendants are equipped with balancing steel wires. The wall lamps come with a cable and a switch or alternatively with a direct wall mount option. The cables of the table, floor, and wall lamps in the Owalo family have a transformer. The cables or any other parts used in Secto Design lamps should not be replaced for safety reasons. Secto Design is not responsible for any damages caused by modifications.

Please regularly ensure that the ring of the lamp holder, which supports the wooden shade, is tightly fastened.

DALI systems

Most Secto Design lamps are attachable to DALI systems with a separate DALI-compatible trailing edge (phase cut off) type dimmer. Due to great variation in DALI systems, Secto Design does not supply DALI-dimmers. Please contact your local electrician.


Secto Design lamps are thoroughly tested, and they comply with all the requirements for CE marking. The models marked with "ETL/CETL" on the North American site are also available with ETL/CETL cabling.

Secto Design Oy is liable for manufacturing flaws when notice is given within a reasonable time. As the lamps are hand-made from birch wood please be aware that, as with every birch tree in the forest, every Secto Design lamp is unique too. Therefore knots and other natural variations are normal.

All the original Secto Design lamps manufactured since December 2017 are sealed with a hologram label.
