Specification Explanations

SPECIFICATION DEFINITION
TYPE Defines what kind of light it is, i.e. halogen, LED, fluorescent, etc.
WATTAGE Defines the energy consumption of the fixture
CRI Important character in areas where color should be truly represented. For applications involving people, a CRI lower than 70 is not recommended. In shopping areas a CRI of 90 and higher is applicable.
LUMENS Responsible for the brightness in a room-the more lumens, the brighter the fixture is illuminating the space
LUMEN PER WATT Determines the efficiency of the lighting system-the higher the lm/W the better the ecological footprint of the product
LUMEN MAINTENANCE How fast LEDs lose their brightness compared to new products (most manufacturers refer to the time when most of the LEDs reach 70% and less of their initial lumen output)
COLOR TEMPERATURE  Defines the mood or ambience in a room. Low-quality lighting fixtures have a very cool temperature as these LEDs are more efficient than warm white LED products. A color temperature higher than 6000K is not recommended for many areas.
BEAM ANGLE The light is radiated into the indicated beam angle-LEDs are direct light sources with typical beam angles of 120° to 180°
LIFE HOURS Defines the lifetime of a LED product. LEDs last from 50,000h up to 100,000h
WORKING VOLTAGE High quality LED products have an integrated driver, retrofit solutions are delivered with the suitable ballast already
FREQUENCY Detail about the admitted voltage frequency
POWER FACTOR Efficiency of the ballast
TOTAL HARMONIC DISTORTION Describes the distortion caused by ballasts and other inductive loads of the input current on alternating current power systems
OPERATING TEMPERATURE The light source is operating under the mentioned conditions according to the manufacturer datasheet-other temperatures will cause the light source to fail or not work properly
IP RATING The protection of the light source, ballast and wiring against liquids and solid objects
DIMMABLE Dimming is the change in light source brightness, mostly undertaken by smart controls
DIMENSIONS The fixture’s size, important for the definition of the mounting position and space
NET WEIGHT The fixture’s weight, important for the mounting construction
HOUSING The housing surrounds the light source and ballast-the higher the IP rating, the better protection against liquids and solid objects
MOUNTING Possible mounting ways-mobile, table, ceiling, wall
WARRANTY How long after purchasing the products are ensured to function properly
