Commercial & Project Lighting Supplier in Kolkata
For architects, contractors, electricians and businesses
Lighting a whole office floor, a chain of shops or a hotel is a different job from lighting one room. Every fitting has to match in colour, the quantities have to arrive together, and someone has to answer the phone when the site needs a change. As a commercial lighting supplier in Kolkata since 1958, Diamond Electrical Industries works with the people who build and run these spaces.
Lighting Supplier in Kolkata for Every Type of Project
Most projects need several kinds of lighting that work together. Our team helps you choose fittings that match in colour temperature and finish across the whole site.
- Offices and co-working spaces: even, glare-free LED panel lights for desks, with downlights for meeting rooms and reception.
- Retail stores and showrooms: tiltable COB spot lights and zoom downlights that put light on the products, not the floor.
- Hotels and restaurants: warm white downlights, cove lighting with LED profiles, and underwater lights for pools and fountains.
- Clinics, schools and institutions: daylight panels and long-life fittings that are easy to maintain.
- Residential projects and builders: matching downlights and profiles across every flat in a building.

LED Lights Wholesale in Kolkata for Trade Buyers
Electricians, contractors and dealers often need the same fitting in fifty or five hundred pieces. For LED lights wholesale in Kolkata, share the product, quantity and delivery location, and ask for a project quote rather than multiplying the single-unit price. Listed website prices are a useful starting point for comparing models before you call.
Industrial Lighting Supplier in Kolkata
Warehouses, factories and yards need light that covers large areas and survives dust, heat and weather. For industrial lighting such as flood lights and high bay lights, tell us the area, mounting height and working hours, and our team will confirm suitable options and availability for your site.
