Eco-Line 3 in 1 Downlight, 8W Switchable
Choosing a colour temperature before the ceiling is even closed can feel like guesswork. The Eco-Line 3 in 1 downlight removes that problem: one 8W COB fitting that switches between Cool White, Warm White and Natural White, so you can decide the tone once the room is lived in.
It uses the same 3" cutout and round body as the standard Eco-Line panel, just with the switchable driver built in. For Kolkata homes and shops that want flexibility without buying three different downlights, this is the simpler route.

Why Choose a 3-in-1 Downlight
A 3-in-1 fitting lets you try Cool White, Warm White or Natural White in the same point and keep whichever suits the room, instead of committing to one tone at the time of wiring. It is especially useful for rooms used for different purposes at different times of day, like a living-cum-dining space.
How the Switch Works
The CCT is changed using the small selector built into the Eco-Line panel's driver, set once during or after installation. There is no separate remote or app needed — it is a simple physical toggle between the three tones.
Installation Notes
The Eco-Line 3 in 1 CCT needs the same 3" round cutout as the standard Eco-Line, so it is a direct swap in an existing false ceiling layout if you are upgrading from fixed-tone downlights. At 8W, plan spacing of roughly 3 to 4 feet between points for even coverage.
Where It Works Best
- Living and dining rooms used across different times of day
- Rental flats and show units where the next occupant may prefer a different tone
- Shops that change displays seasonally and want flexible lighting
- Any room where you are unsure between Cool, Warm or Natural White

Frequently Asked Questions
What is the price of the Eco-Line 3 in 1 downlight?
The current price, including any running offer, is shown on this product page. It is an 8W COB fitting with a 3" cutout that switches between Cool White, Warm White and Natural White.
How do I change the colour temperature on the Eco-Line 3-in-1?
The Eco-Line panel has a small CCT selector on the fitting's driver. You set it to Cool White, Warm White or Natural White during or after installation; no remote or app is needed.
Is the Eco-Line 3-in-1 the same size as the regular Eco-Line?
Yes, it uses the same 8W wattage and 3" round cutout as the standard Eco-Line, so it can replace a fixed-tone Eco-Line in an existing false ceiling without changing the cutout.
Why pay more for a 3 in 1 downlight instead of a fixed CCT one?
It suits rooms with mixed use, rental flats, or anyone unsure which white tone they will prefer long-term.
Can the Eco-Line 3-in-1 be mixed with other COB downlights in the same ceiling?
Yes, it is commonly combined with other fittings from the COB downlight range for mixed general and accent lighting in the same room.
Is the Eco-Line 3-in-1 good for a shop that changes seasonal displays?
Yes. Since the CCT can be switched without rewiring, shops that change their look for different seasons or festivals can adjust the lighting tone to match without new fittings.
