Base: the base of a lamp is the part that provides electrical and mechanical connection to the light fixture. A standardized system of lamp bases guarantees interoperability and easy replacement.
Verbatim offers LED lamps with the most commonly used lamp bases.
Beam angle: defined as the angle at which the luminous intensity of a directional light source is 50% of the maximum light intensity of emitted light. It is the angle between peak intensity and 50% of peak intensity at full width – referring to both sides of the beam axis.

Colour: indicates the housing colour (black, white, silver) of the product.
Colour rendering index (CRI): describes the colour rendering properties, the visual appearance of objects lit by a light source, compared to a reference source of the same colour temperature. On a scale from 0 to 100, it indicates the ability to faithfully reveal colours and depends on the spectrum of the light source.
Colour temperature in Kelvin (K): is the colour appearance of light in comparison to an ideal black body radiator. According to EN12464, colour temperatures are classified in 3 groups: Warm white (<3300K), neutral or intermediate white (3300K-5300K) and cold white (>5300K).
DALI: Digital Addressable Lighting Interface - DALI is a global standard and open protocol for communications and control of lighting equipment including control gears and control devices. It guarantees interoperability with DALI system components and intelligent control of lighting.
Dimmable via leading and trailing edge.
Energy class the energy classes according to EU Directive 1194/2012 categorize energy efficiency and eco-design requirements for directional and non-directional LED lamps. Verbatim’s LED lamp feature energy classes from A to A++.

Ingress protection: the IP (ingress protection) rating indicates the level of protection against intrusion and water. The first digit refers to the protection from solid objects whereas the second digit indicates protection from liquids. Generally, the higher the value, the more protected a LED device is against either intrusion or water – starting with “0” for no protection at all.
Installation: to be installed in an open fixture
Lifetime (L70) in hours: defined as the time until the light output of a LED device has decreased to 70% of the initial output. It also refers to lumen depreciation which is the decrease in lumen output that occurs as a LED device is operated.
  Safety class: the safety classes define the protection and insulation requirements against electric shock. Whereas protection in Class III for low voltage lighting relies only on supply at SELV, Class I requires means of earthing and Class III double-insulated safety precautions.
Class I
Luminaires in this class are electrically insulated and provided with a connection to earth. Earthing protects exposed metal parts that could become live in the event of basic insulation failure.
Class II
Luminaires in this class are designed and constructed so that protection against electric shock does not rely on basic insulation only. This can be achieved by means of reinforced or double insulation. No provision for earthing is required.
Class III
Here protection against electric shock relies on supply at Safety Extra - Low Voltage (SELV) and in which voltages higher than those of SELV are not generated (max. 50V ac rms).
Voltage: indicates the voltage that is required to operate the LED device. For operating 12V LED lamps, an additional electric transformer is required.
Weight: indicates the weight of the product measured in grams (g).
1-10V analog dimmable lighting system via a twowire, low-voltage control line connecting control gear and controllers. Light levels are scaled so that at 10V, the controlled light is at 100% of its potential output whereas 1V signifies 10% of the potential light output
850°C glow wire test: the glow wire test according to EN 60695-2 is used to test flammability and fire resistance of a product. All Verbatim’s LED devices pass the glow wire test at 650°C. If stated differently, the test has been conducted at 850°C.
