LED downlight — SQUARE DOUBLE, adjustable & dimmable 2x9W, brushed aluminium, high CRI97, 4000K
LED FIRE CANTLE (brushed aluminium) luminaire is dimmable and moisture-proof (IP44). The luminaire is equivalent to 2x50W halogen, with a consumption of only 2x9W. It has a colour rendering index (CRI) of 97 and reproduces colours in a natural way.
Superior technology
The LED TUPLA KANTTI (brushed aluminium) luminaire is dimmable and moisture-proof (IP44). With a colour rendering index (CRI) of 97, the colours in your interior will look natural. The luminaire is equivalent to 2x50W halogen (2x600 lumens) and is available in both 3000K (warm white) and 4000K (neutral white).
LED TUPLA KANTTI is a flush mount luminaire in cast aluminium with the LED circuitry mounted directly on the frame. The solution achieves maximum thermal conductivity and safe operating temperature (below 50 degrees Celsius). The low operating temperature guarantees a long lifetime, 50,000 and we grant a 5 year warranty on our manufactured luminaire! The luminaire is also available in matt white.

Led lamp installation
The luminaire is directional, 0-28 degrees. The luminaire is very low, only 45-50mm high (6mm more when oriented)! The luminaire will therefore fit into a typical roof structure with only 48x48mm of insulation and 13mm plasterboard under the vapour barrier. We recommend installing a piece of board or plasterboard above the luminaire to prevent the insulation from sagging. The mounting hole is an ellipse, 2x80mm holes are drilled 1cm apart and any excess pieces are removed between the holes.
Each luminaire is supplied with its own chained power supply which fits through the mounting hole into the mounting space. By moving the power supply away from the luminaire, we prevent the power supply from heating up the luminaire, and we can keep the size of the luminaire small. The power supplies are long-lived and this also allows us to avoid the typical problem with halogen lamps, where one power supply is subjected to a heavy load and gets hot, and breaks the luminaire. There is a quick connector between the luminaire and the power supply for easy installation.
Dimming
The luminaire can be dimmed with a wireless dimmer or TRIAC dimmers, from the ENSIO side, and they also work with home automation systems such as KNX, Talomatti, etc. You can also order suitable dimmers from us, "Led dimmers"
They work very well for example:
- ABB (former Ensto) Jussi 6523U
- Schneider (ex strömfors) transistor controller 315W/VA EXXACT
NOTE!
Two versions of the lamp are available! The old version, with three led circuits and CRI85 colour rendering, and the new version (this one) with light coming from one point and a colour rendering index of 97! The old version is IP21 and the new version is IP44.
All our luminaires are CE and RoHS approved.

LED DOUBLE SQUARE is adjustable and can be tilted 0-28 degrees. This light is very low, only 45-50mm in height. Fits to typical ceiling structure where there is 48x48 ceiling frame and 13mm plaster board. We recommend you to install a piece of plaster board on top of the light to stop the insulation from pressing on to the light. Installation hole is 2x80mm in diameter (holes 1 cm apart from each other, cut the excess plaster from between the holes).
All led spots come with driver that fits in from the installation hole. By having a separate driver, we have reduced the temperature of the light, making it last longer. There is a quick connector on the cord between the lamps and the driver as well as two inputs to make installation easy.

WHAT IS CRI, THE COLOUR RENDERING INDEX
High quality LED lights also have a high colour rendering index, or CRI. A good colour rendering index (CRI) for home use is above 90, and nowadays many market lights are unfortunately closer to 80.
CRI tells you how well an LED light displays colours as they should be. For designers and architects, as well as interior designers, it should be one of the most important considerations. Make sure the lighting is perfect so that your artwork is what it is meant to be.
Colour rendering index
The colour rendering index is expressed as a number on a scale from zero to 100, where 0 = no colour rendering and 100 = full colour rendering. The colour rendering index of LED lights is also known as Ra, which is measured on a smaller scale than CRI. This Ra value does not include red tones or skin tones, for example, so it is a 'glossed' figure for the true quality of an LED light.
RA value
The Ra value measures the reproduction of colours using eight different reference colours. CRI takes into account the wider (15) wavelength range, including reds and other warm colours.
The Ra value is calculated by cutting the wavelength range, weighting the blue and violet tones, and calculating the weighted average of R numbers 1-8.
Excluded from the Ra value are, for example, the colour rendering of bright reds, yellows and greens, and shades close to skin tone. These are described by R-values between 9 and 15. The following is a picture of a measurement result that easily confuses the consumer.
This measurement is from a 9W CCT Led spot
