What is light? Light is a kind of energy. As part of the electromagnetic spectrum, it is a primary tool for perceiving the world and communicating within it. Colour is a property of light. It can only be seen by the human eye when illuminated. What we see is a result of the way an object interacts with light. Colour Temperature Colour temperature - how we measure a light’s colour Circadian rhythm - our sleep and wake cycle, as dictated by the colour temperature we are exposed to Cool midday light - suppresses melatonin, making us feel more alert Warm evening light - releases melatonin, preparing us for sleep Evolution of Lighting *Image* Types of Lighting - How you can use them *Image* Tala Tala is an award-winning lighting brand, founded on the premise that good design can help mitigate climate change. From our London-based studio, we explore the tension between sustainability, technology and design through our wide-ranging collections. Long lifespan With a lifetime of 30,000 hours on our straight filament lights and 15,000 hours on our curved filament lights, our products last an average of 2 times longer than other LED brands, and 10 times longer than incandescent lights. Because time is money. CRI 95 CRI is a measure of how accurately colours are rendered in comparison to natural daylight. Thanks to the phosphor coating on our filaments, we guarantee a minimum CRI of 95, which makes people and objects look great in a space, enhancing the experience and showing off the beautiful furniture you’ve carefully selected. Retrofittable Our standard base sizes (E12/14, E26/27) easily retrofit into a variety of fixtures. Simply twist our lights into your preferred fitting and watch it come to life. Achieve a higher consistency of light without having to transform your entire interior. Smooth dimming All our lights dim smoothly down to 5%, giving you a bigger range and more control over your desired light output to suit your ever-changing schedule, making your interior work as hard as you do. We recommend leading and trailing edge systems to ensure optimal compatibility. 2200K A warm colour temperature giving off a decorative glow that puts less strain on the eye, creating a relaxing ambience for socialising and winding down in the evenings. 2700K A higher colour temperature that stimulates alertness and focus, leading to improved productivity in workspaces and better lighting for task-based activities. Glass All our lights are made from high quality, scratch-resistant glass. Choose a tinted finish for reduced glare from the filaments within, or clear glass if you are looking for greater clarity of light output. Colour Rendering Index (C.R.I) C.R.I is a scale from 0 to 100 percent indicating how accurate a "given" light source is at rendering color when compared to a "reference" light source. Our components Glass: All our lights are made from high quality, scratch-resistant glass. Choose a tinted finish for reduced glare from the filaments within, or clear glass if you are looking for greater clarity of light output. Sapphire substrate: Allows greater heat dissipation and transparency than the market standard, resulting in a longer lasting and more even dispersion of light. Phosphor coating: We have carefully calibrated our phosphor mix so that it is tuned to the exact colour temperature and CRI we specify.
