Food was $12 per person for 150 guests while we bought our wine and beer for about $200-300. We spent about $600 in total for a wedding with 45 guests. We opted for self-catering with the menu made up of food that was easy to prepare in advance and reheat on the big day.
The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.or monochromatic light of this wavelength, the amount of illuminance for a given amount of irradiance is maximum: 683.002 lux per W/m 2; the irradiance needed to make one lux at this wavelength is about 1.464 mW /m 2. Other wavelengths of visible light produce fewer lux per watt-per-meter-squared.
Just move the meter around to different areas and take a few readings. Light meters often give readings measured in lux. A lux is the light from one candle at one meter away spread over a square area one-meter wide. Direct sunlight is approximately 32,000 to 100,000 lux. Full-sun plants usually need at least 25,000 to 50,000 lux to do well, with increased productivity occurring when light levels are near full sunlight. Light Reflection and Hydroponics Light bulbs give off light in all directions, so there are lamp hoods designed to reflect light from the top and sides of the bulb down into the garden.
