Recessed floor light Micro
This LED in-ground luminaire is the first choice when you are looking for a very small luminaire with a shallow mounting depth. The beam angle of 120° means a wide, diffuse radiation.
Material: glass, body aluminum, front ring stainless steel
Supplied with a mounting sleeve
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 with e.g. 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 2.86V = 8.58V
- Multiply the number of luminaires with the wattage
--> Example: 3 lights are to be used: 3 x 1W = 3W
------------------------------------------------------------------------------------------------
Result: the LED converter must have a power of at least 3W and be able to provide an output voltage of 8.58V.
Note: On request this luminaire is also available in surface white and / or with the light color 4000K (min. 10 pcs.)

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
