Recessed floor luminaire with beveled edge and deeper LED
- Order number: SW11114
Recessed floor luminaire with beveled edge and deeper LED
This LED recessed floor luminaire is the first choice if you are looking for a very small luminaire with the highest possible luminous intensity. Due to the LED light source, which is seated lower than the model SW11110, glare occurs very late, which means that the spotlight offers greater visual comfort. The reflector of this model is additionally selectable in surface gold, which creates a warm color tone. In the combination surface black / reflector gold, the spotlight also looks very noble. The lower part of the reflector is always silver for maximum light output.
Fig. 1: Here you can see the two-color structure of the reflector: silver at the bottom in the area of the LED, gold in the upper area.
Fig. 2: Variant in black surface, straight edge, black reflector
Material: glass, aluminum or optionally stainless steel
Supplied without installation sleeve, which can be ordered as an accessory.
Wiring:
The aim of a cost-effective installation should be to connect as many luminaires as possible to one LED converter. Here, the wiring type "serial wiring" should be considered. If this is not possible, each luminaire is operated e.g. with a 4W LED converter and connected to 230V.
Principle of serial wiring:
Procedure for rough calculation of the required LED converter:
- Multiply the number of luminaires by the flux voltage.
--> Example: 3 luminaires are to be used: 3 x 10,95V = 32,85V
- Multiply number of luminaires by wattage
--> Example: 3 lights are to be used: 3 x 3,82W = 11,46W
------------------------------------------------------------------------------------------------
Result: the LED converter must have a power of at least 11.46W and be able to provide an output voltage of 32.85V.

A few information about the technical data
- What is luminous flux?
The luminous flux Φ - measured in lumens (lm) - is the light output of a light source. It describes the power emitted by the light source in all directions in the visible range. To get a rough idea of what this value means, here are a few comparisons:
Candle: 12lm
230V halogen bulb with base GU10, 50W: 345lm
230V halogen bulb with base G9, 60W: 740lm
12V halogen bulb with socket GX5.3 (GU5.3), 35W: 450lm
12V halogen bulb with socket GX5.3 (GU5.3), 50W: 720lm
12V halogen bulb with base G4, 20W: 257lm
12V halogen bulb with base GY6.35, 50W: 840lm
230V halogen rod with base R7s, 100W: 1200lm
- What does color temperature mean?
Roughly speaking, the color temperature indicates how warm or cold especially white light is. The oneness is Kelvin (K). The lower the Kelvin value, the warmer the light gets. The light of a commercial light bulb here would correspond to about 2700K, a candle has about 1500K. The higher the Kelvin value becomes, the colder the blue becomes the light. Daylight is compared with about 7000K. A rough classification of the light color is:
- 2,700 to 3,250 Kelvin: warm white
- 3,250 to 5,250 Kelvin: neutral white
- 5,250 to 8,000 Kelvin: daylight white
- What does the color rendering index called RA or CRI?
The color rendering index indicates the degree of correspondence of the seen body color with its appearance under the respective reference light source. The smaller the deviation, the better the color rendering property. A light source with RA = 100 reproduces all colors very well. The lower the RA value, the less well the colors are rendered. In bathrooms and dressing rooms with mirrors, we generally recommend the use of luminaires and light sources with a high RA value of at least 90.
RA 70-80: medium color rendering
RA 80-90: good color reproduction
Ra 90-100 very good color reproduction
