Bulk LED lights from a trusted lighting brand in India since 1958
Diamond Electrical Industries began in Kolkata in 1958 and has worked in LED lighting since 2005. Many buyers call us one of the best lighting brands in Kolkata, and we now supply bulk LED lights to resellers, factories, contractors and interior designers across India.
Buying bulk LED lights from one supplier is like buying bricks from one kiln: every batch matches. The beam, colour and finish stay the same from the first floor to the last, and you have one team to call if anything needs attention.
LED light wholesale for resellers and dealers
Electrical shops need steady stock of fast-moving items: 7W to 12W COB downlights, panel lights, 12V and 24V strip lights, bulbs, tube lights and 50W to 100W flood lights. We supply these at dealer slab rates with repeat-order support, so you can price competitively and keep margins healthy.
Industrial LED lights for factories and warehouses
Sheds, warehouses and yards use industrial LED lights such as 50W to 200W high bay lights and heavy-duty LED flood lights. LED fittings switch on instantly and use far less power than old metal halide lamps.
Project lighting for interior designers and architects
Designers need matching fittings across a whole site. Our COB LED downlights, LED profile lights, track lights and LED strip lights come in warm, natural, cool and 3-in-1 colour, with samples available before you order.
