LED Skylights: Artificial Sky Ceilings for Rooms Without Daylight

What Is an Artificial Skylight?

A regular LED panel spreads even white light across a room. An artificial skylight is built to produce the appearance of sky, not just brightness.

The fixtures in this collection use micro-nano optical technology based on Rayleigh scattering. This is the same effect that makes the daytime sky look blue: light passing through the atmosphere scatters, and blue wavelengths spread across the sky. By recreating that scattering inside the fixture, the skylight gives a sense of depth and openness that a flat panel cannot.

This makes skylight lighting a design element as much as a light source. It is chosen for how a room feels, not only for how bright it is. For a closer look at the science, read our guide on how an artificial skylight brings the sky indoors.

The Nerva Square Skylight

The Nerva Square Skylight is the current model in this collection. It is a square fixture designed to sit in the ceiling like a real opening to the sky.

• Colour temperature control: Smart control allows stepless adjustment between 2200K and 7000K. At the warm end, the light resembles late-evening amber. At the cool end, it matches the brighter white-blue of midday.
• Colour rendering: The light source is specified with a colour rendering index above Ra 95. Surfaces, fabrics and skin tones look close to how they appear in daylight.
• Custom sizing: The skylight can be made in customised dimensions to suit specific ceiling layouts, from narrow corridors to larger living areas.
• Smart control: The system works with the Tuya / Smart Life app over Zigbee or Wi-Fi. Multiple units can be grouped so that a larger sky ceiling responds as one.
• Professional installation: Installation is included. Our team handles mounting and setup so the open-roof effect looks convincing once the ceiling is finished.

Where Skylight Lighting Works Well

An LED skylight is most useful where daylight is missing and a room feels enclosed as a result. In many Kolkata apartments and older buildings, inner rooms face narrow light wells or have no window at all. In homes like these, an artificial skylight can change how the space feels without structural work on the roof.

Common applications include:

• Windowless bedrooms, studies and dressing rooms, where a warm setting in the evening and a cooler setting during the day give the room a natural rhythm.
• Corridors and passages, where custom sizing lets the fixture follow a long, narrow ceiling.
• Living and dining areas in the centre of an apartment, where a skylight becomes a focal point in a false ceiling.
• Offices, meeting rooms and cabins in the middle of a floor plate with no outside wall.
• Hospitality and retail interiors, such as hotel lobbies, lounges and showroom ceilings, where the sky effect is part of the design.

What to Consider Before You Buy an LED Skylight

• Ceiling size and layout. Because sizes can be customised, start with the area of ceiling you want to open up. Share your ceiling dimensions and false ceiling details with our team before ordering.
• One unit or a sky ceiling. A single fixture works as a feature in a smaller room. Larger spaces can use several grouped units that change colour temperature together.
• How you want to control it. The skylight connects over Zigbee or Wi-Fi through the Tuya / Smart Life app. Zigbee setups generally need a compatible gateway, so check your existing smart home system when planning.
• Colour temperature use. Think about how the room is used across the day. A bedroom may spend most evenings at the warm end, while an office may stay closer to daylight white during working hours.
• Installation. Installation is included with every skylight. The fixture needs careful positioning for the sky effect to look right, so plan for this as part of the ceiling work, not as a last-minute addition.

LED Skylight Price

The Nerva Square Skylight is currently listed at ₹20,000 on our store. For custom dimensions, multiple grouped units or a complete sky ceiling, contact our team with your room measurements for a project quotation. When comparing LED skylight prices from different suppliers, check whether each quote includes custom sizing, smart control and installation. These can change the real cost of a project considerably.

Why Choose Diamond Electrical Industries

Diamond Electrical Industries has been part of Kolkata's lighting trade since 1958. Our range covers residential, commercial and architectural lighting. That means a skylight can be planned alongside the rest of the ceiling, including recessed downlights, linear profile lighting and smart control products, instead of being sourced separately.

Every skylight comes with professional installation. The same team that supplies the fixture is responsible for making the sky effect work in your space.
