Mahalaya is here and most Kolkata homes still have one job left on the list: lighting. If you have been putting off that LED lights offer search because the usual prices felt steep, this is the year to stop waiting. Diamond Electrical Industries has put its entire online catalogue, from COB downlights to decorative strip lights, at a flat 50% off LED lights for the Puja season, and the sale is live on dewdiamond.com right now.
This is not a one-category clearance. Every room that needs attention before Shashthi, the drawing room where relatives will sit, the balcony where the alpona catches the evening light, the puja ghar itself, is covered by the same Puja lighting offer.
Why this LED lights offer matters right before Puja
Durga Puja in Kolkata this year runs from Shashthi on 17 October to Bijoya Dashami on 21 October, with Mahalaya falling tomorrow, 10 October. That leaves roughly a week to finish the home before guests start arriving after pandal rounds. A Durga Puja lighting Kolkata shopper at this point is usually not choosing between brands. They are choosing between buying now at a lower price or paying full rate later because the ceiling has been bare since Rath Yatra.
A flat 50% off sitewide changes that calculation. A COB downlight that would normally stretch a Salt Lake 3BHK budget now costs the same as the basic option did last season, with better output.
Which lights actually change how a Puja evening feels
A single bright tube light in the drawing room photographs flat and feels harsh once thirty people are standing under it after the Saptami pandal round. Layered lighting does more work with less wattage.
COB downlights in the false ceiling handle the base layer. Diamond's COB downlights and spot lights for false ceilings collection covers everything from a simple 5W spot for a passage to a tunable white fixture that shifts between warm and cool light depending on who is visiting. During the offer, a compact downlight such as the D020462 is priced at ₹400 against its usual ₹800, and the ECO STAR 10W sits at ₹250 against ₹500, this is the LED light price Puja shoppers have been waiting for.
Strip and rope lights are the layer that actually reads as festive. Run one along the showcase, the false ceiling edge, or the thakur dalan border, and a plain room starts to look dressed for the occasion. Diamond's strips and rope lights range is built for exactly this kind of coving and outline work, and it carries the same 50% off LED lights pricing.
Track lights earn their place where you want to point light at something specific: a framed photo of the family deity, the thakur idol itself. Think of a track light like a torch bolted to the ceiling: it does not flood the whole room, it picks out one thing. Diamond's track lights collection is part of the same Puja lighting offer.
A practical example: a 12 x 10 ft drawing room in a Behala flat usually needs four to six downlights for base light, one strip along the false ceiling border, and one or two track lights for a feature wall or idol corner. At the discounted LED light price, that full setup now costs roughly what four downlights alone would have cost before the sale.
How much do these lights cost during the 50% off sale
| Fixture | Usual price | Puja offer price |
|---|---|---|
| COB downlight (D020462, 7W) | ₹800 | ₹400 |
| COB downlight (DWDN, 12W) | ₹1,300 | ₹650 |
| Tunable COB spotlight (SAPPHIRE, 12W) | ₹1,500 | ₹750 |
| COB downlight (ECO STAR, 10W) | ₹500 | ₹250 |
These are live catalogue prices on dewdiamond.com, not estimates. Because the discount applies across the site rather than a handful of marked-down items, the same LED light price math holds whether buying two downlights for a passage or twenty for a full flat.
Durga Puja lighting Kolkata: what to prioritise if you are buying in a hurry
A direct answer first: if time is short, prioritise the drawing room and the entry, since guests spend the first and last few minutes of a visit there, then the puja ghar, then everywhere else.
Older houses in north and central Kolkata, with high ceilings and thakur dalans, generally do better with warm light and surface-mounted or track fixtures, since rewiring a false ceiling at this stage is not realistic. South Kolkata and the Salt Lake, New Town and EM Bypass belt, where most homes already have false ceilings, can go straight to COB downlights without extra carpentry.
Colour temperature is worth getting right before anything else. Warm white (around 2700K) reads like the glow of a diya and suits a puja ghar or a drawing room for conversation. Cool white (around 6000K) reads closer to a hospital corridor and suits a kitchen or passage where task visibility matters more than mood. Most of the COB range in this offer, including the ROLEX and the 5x2/10x2 Linear, comes with a 3-in-1 switch that picks warm, natural or cool white on the same fixture.
Energy and safety during a high-usage festive week
A home running decorative lights for extra hours a day through Puja week notices it on the bill if the fixtures are inefficient. LED fixtures draw a fraction of the electricity that incandescent or CFL options need for the same brightness. The Bureau of Energy Efficiency publishes star ratings for anyone who wants to compare efficiency claims before buying.

With Shashthi a week away, this discount is tied to the festival rather than running indefinitely, so a decision made this week is the one that actually gets installed before guests arrive.
Frequently Asked Questions
How long is the 50% off LED lights sale valid?
The flat 50% off sale is running sitewide on dewdiamond.com for the Durga Puja season. Buying before Shashthi on 17 October is the safest way to get fixtures installed before guests arrive.
Is the Puja lighting offer available at the Esplanade East showroom too?
Yes. The same discounted pricing applies both online and at the Diamond Electrical showroom at 11A, Esplanade East, above K.C. Das, Kolkata 700069, so a fixture can be seen lit in person first.
What is the difference between warm white and cool white LED lights for Puja decoration?
Warm white (around 2700K) gives a soft, yellow-toned glow close to a diya and suits drawing rooms and puja ghars. Cool white (around 6000K) is brighter and bluer, better suited to kitchens or passages where task visibility matters more than mood.
How many downlights does a typical Kolkata flat need for Puja?
A 10 x 12 ft room generally needs four to six COB downlights for even base lighting, depending on wattage and whether a false ceiling is already in place. One strip light along the ceiling edge usually finishes the festive look.
Does the LED lights offer apply to shop and showroom decoration too?
Yes. The 50% off pricing applies across the full catalogue, so Durga Puja lighting Kolkata shoppers buying for a home and shop owners decorating a storefront on Esplanade or Gariahat pay the same discounted LED light price.
Do LED downlights work well in older, high-ceiling Kolkata houses?
Recessed COB downlights need a false ceiling, which many older north and central Kolkata houses do not have. Surface-mounted or track lights are the more practical choice there, and both are included in the current Puja lighting offer.
Ready to finish the room before Shashthi. Browse the LED lights offer on dewdiamond.com or visit the showroom at 11A, Esplanade East, above K.C. Das, Kolkata 700069, before Puja week pricing ends.
