What is PAR. Lighting intensity is measured in lumens. One lumen is equal to the light given off by, 1 birthday cake candle, 1ft away. For example: A bulb emitting 600 Lumens, is as bright as 600 candles, one foot away. Lumens will tell you how bright a light is, but, plants will not use light …

My 50 micromols at the substrate seems to grow plants (and algae) as if it is higher than low light, but not really high light. PAR. The amount of usable light for plants is expressed as a frequency value within the electromagnetic (light) spectrum. This spectrum runs from UV light to infrared light. The light your plants have available for photosynthesis is called PAR (Photosynthetic Active Radiation). PAR falls within a frequency band of 400-720 nanometers.

MFL, WFL, and NSP refer to three types of light beam spread, or the nature of the distribution light produced by a lamp. Deciding between the three types of beam spread will depend upon the type of light spread you need. The Beam Angle for a light bulb is the angle in degrees at which the light is distributed. Based on

Use PAR bulbs when attempting to put a focused beam of light on an object such as in track lighting or illuminating artwork. PAR spot lights also work great as outdoor security lighting. So What Is a PAR? Essentially a PAR is the amount of light that is actually available to be used during the photosynthesis process. There may be more light emitted from a particular source, but your plants don’t make use of all of it – some of it has no real effect on the photosynthesis process.

PAR Meters can be handy tools to measure light intensity at discrete points, but how meaning actual photosynthetic response is limited to canopy level foliage.

Photosynthetically active radiation (PAR) is the available light required for photosynthesis to take place. The wavelengths of photosynthetically active radiation that plants can use are generally in the range of 400-700 nanometers (nm).

All light consists of small packets of energy called photons. The number of photons emitted by a light source in the PAR range is known as the photosynthetic photon flux or PPF. PAR is essentially a measurement of light emission within the photosynthetic range of 400-700nm. This represents the area of light that plants use for photosynthesis, or to grow. PAR is measured by the amount of micro moles of light per square meter per second. Although PAR is a key measurement, it only tells one part of the story. PAR is an acronym for parabolic aluminized reflector and is used to designate a sealed-beam lamp similar to the headlight in an automobile.

PAR is an acronym for parabolic aluminized reflector and is used to designate a sealed-beam lamp similar to the headlight in an automobile. PAR lamps are differentiated according to their diameter, which is measured in eighths of an inch.
