TECHNICAL INFORMATION
To understand lighting in its entirety, comprehend its evolution and provide innovative solutions to practical operational problems is Magnitech’s drive.
Becoming specialists in the science of light and how to encase it for maximum efficiency and longevity is why Magnitech’s products still burn today after being installed 25-30 years ago.
IP RATING
IP rating defines the levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies.
ik rating
IK rating defines the degrees of protection provided by electrical enclosures (including luminaires) against external mechanical impacts.
WHAT IS LIGHT
Light is that part of the electromagnetic spectrum that is perceived by our eyes. The wavelength range is between 380 and 780nm..
PHOTOMETRY 101
Photometry is a branch of science concerned with the measurement of the brightness of light from a human perspective.
Introduction to photometrics
Testing the amount, colour, quality and spatial distribution of light emitted from lamps, LEDs and luminaires.
CCT
The correlated colour temperature (CCT) is a specification of the colour appearance of the light emitted by a lamp, relating its colour to the colour of light from a reference source when heated to a particular temperature, measured in degrees Kelvin (K).
COLOUR RENDERING
The rendition of colour by a lamp is specified by the CIE colour rendering index (CRI or Ra) and is a measure of the light source to faithfully render the appearance of a gamut of colours spanning the colour space.
LIGHT LEVELS
The amount of light measured in a plane. The work plane is where the most important tasks in the room or space are performed.
LM79 TESTING
As the development of LED technology continues to grow and diversifies, the need for consistent and standardized testing procedures for LED has become more prevalent than ever. The test can only be performed by a NIST NVLAP Accredited testing laboratory for LM-79.
LM80 TESTING
The LM-80 standard is accepted worldwide with slight variations in different countries. The data resulting from the LM-80 measurements are matrices of lumen maintenance values.
TM21 REPORTING
The Illuminating Engineering Society of North America (IESNA) approved method for taking LM-80 data and making useful LED lifetime projections. It proves a recommendation for projecting long term lumen maintenance of LED light sources using LM-80-08 lumen maintenance data.
HOW TO READ AN AGI LIGHTING DESIGN
AGI is a simulation tool used for designing lighting projects and calculating the amount of light that will be delivered based on user-set parameters.
LIGHT DISTRIBUTION
Light distribution is the projected pattern of light a fixture will disperse onto a surface.
LED LIFETIME
A brief analysis of terms used to define LED lifetime and maintenance, and the factors involved in its assessment.
CHEMICAL RESISTANCE OF LUMINAIRE MATERIALS
Industrial luminaires are manufactured in a variety of materials, each specifically selected as being the most resistant to chemical corrosion & other related elements. The resistance tables give a general overview regarding the resistance to chemical attack on luminaire materials and generally applicable for ambient temperatures up to 60˚C.
HAZARDOUS LOCATIONS
A hazardous area can be defined as any location where there is risk of an explosion. But every hazardous area is different and each has specific requirements depending on the nature of the atmosphere and the elements that are present.
