The IP value indicates the degree of protection against the ingress of moisture and dust. The 1st digit (0 = not protected until 6 = completely dustproof) indicates the protection against dust. The 2nd digit (0 = not protected until 8 = protected against immersion) indicates the protection against water. Products with an IP44 rating are splashproof and products with an IP65 rating or higher are (completely) dustproof and waterproof.
Dimmable bulbs work in combination with a dimmer switch and allow you to determine the desired light output. Dimming also provides energy saving potential because less power is required when the lamp is producing less light.
Colour temperature (Kelvin)
Light colour is also known as colour temperature and is expressed in Kelvin (K). You can choose from:
Extra warm white (1700K - 2700K). Atmospheric light. For places with a relaxing character.
Warm white (>2800K). Neutral and soft light. For common areas such as halls, corridors, foyers.
Cool white (>3400K). Fresh and natural light. Good for focus/concentration in schools and offices
Daylight white (>5000K). Equals natural daylight. Suitable for situations where a lot of light is needed.
Beam Angle (degree)
A beam angle indicates the angle of the light beam coming from a light source. The smaller the radiation angle in degrees (D), the narrower the beam angle.
Colour of the Fixture
Lighting with a built-in emergency lighting unit (battery) continues to burn for a certain time if the power fails.
Type of sensor
The wattage indicates how much energy a light source consumes. With LED lighting, the wattage is considerably lower than with conventional lighting. LED lamps with a higher wattage generally also have a higher light intensity (number of lumens).
