Lighting Question #1: What is colour temperature?
The colour or warmth of white light is ranked on a scale, The Kelvin scale, the warmer the colour the lower the colour temperature. A 'warm' colour temperature is typically 3,000K or less. A 'cool' white light bulb commonly has a colour temperature of 4,000K and higher on the Kelvin scale.
Lighting Question #2: What is CRI?
CRI stands for Colour Rendering Index, this is measured from 0-100, with a perfect 100 indicating that colours of objects under the light source appear the same as they would under natural sunlight. All Zico Lighting light bulbs have a CRI of 90 as a minimum, this creates great colour rendering. Colours appear as they should, subtle tones pop out and are accented, skin tones look beautiful, art comes alive, backsplashes and paint show their true colours.
Lighting Question #3: What are Lumens?
Lumens is the unit of measure that determines how much light a bulb gives off. More lumens (Lm) means it’s a brighter light, less lumens means a dimmer light. When buying light bulbs, think lumens, not watts.
Lighting Question #4: What are the benefits of LED light bulbs?
- · Long Lifespan
- · Energy Efficiency
- · Improved Environmental Performance
- · The Ability to Operate in Cold Conditions
- · No Heat or UV Emissions
- · Design Flexibility
- · Instant Lighting and the Ability to Withstand Frequent Switching
- · Low Voltage Operation
Lighting Question #5: What are LED filament bulbs?
An LED filament light bulb is an LED light bulb which is designed to resemble a traditional incandescent light bulb with visible filaments for aesthetic and light distribution purposes, but with the high efficiency of light-emitting diodes (LEDs). For example our beautiful helix range gives a retro look and feel to the light bulb.
Lighting Question #6: What is the difference between dimmable and non-dimmable light bulbs?
Dimmable LED light bulbs mean you can adjust the brightness or lumen levels according to your needs. For example, you can use a brighter light (higher lumens) when you're working, and dim to lower lumens when watching a movie or reading.
Lighting Question #7: What is layered lighting?
A phrase you might encounter in the lighting design world is ‘layered lighting’, simply put, layered lighting involves the use of multiple lighting types to create a well-lit and balanced space. Lighting design has three distinct layers: Ambient, Task, and Accent Lighting.
- · The ambient layer provides the illumination required to see the space in its entirety, this is usually the main light in the room.
- · The task layer is to enhance the function of specific areas. In an office, this might be the desk workspace. In a kitchen, task lighting illuminates cooking surfaces or countertops, most commonly this would require a GU10 light bulb.
- · The accent layer adds a decorative finish by complimenting the other two layers and highlighting architectural features like columns, floral arrangements, and wall art using our picture lights.
