Top 10 LED light brands in India, and where Diamond fits

How to choose wholesale LED strip lights

LED density works like thread count in a bedsheet: more LEDs per metre gives a smoother, brighter line with fewer dots.

12V vs 24V vs 220V LED strip lights

12V strips suit short runs like cabinets. 24V strips carry power further with less dimming, so they suit long coves. 220V strips run straight from mains power and suit outdoor outlines and festive work.

COB strip and RGB strip lights

COB strips give a dot-free glow, best inside aluminium profiles. RGB strips add colour effects for retail, hospitality and events. Size each LED driver about 20 percent above the strip load.

LED strip lights wholesale for decorators and dealers

Decorators, pandal makers and electrical shops buy our strips and rope lights by the roll. Share your monthly need for dealer pricing.

Every order is packed and supplied by Diamond Electrical Industries.

Frequently asked questions

Which is better, 12V or 24V strip lights?

For runs longer than about 5 metres, 24V is usually better because the far end stays as bright as the start. 12V is fine for short runs.

Do LED strip lights need a driver?

12V, 24V and 5V strips need a driver. 220V strips connect to mains directly. We supply matching drivers with bulk orders.

Can LED strips be used outdoors?

Use 220V strips or rope lights made for outdoor use and protect every joint from water. Indoor 12V strips should not face rain.

Where can I buy LED lights in bulk in India?

You can buy bulk LED lights online direct from Diamond Electrical Industries, a trusted lighting brand in India since 1958, with a GST bill and delivery to your city. We also have city pages with local market guides, like the LED light wholesale market in Delhi.

What is the wholesale price of a 12 watt LED bulb?

Our 12W LED bulb (B22 or E27) is ₹60 per piece + GST, about ₹71 including 18% GST. The 20W bulb is ₹125 + GST. Larger quantities get a better rate on request.

Where can I buy the cheapest LED lights?

The lowest sticker price is often an unbranded light with no bill or warranty. For the best value, buy direct with a GST invoice: our 12W LED bulb is ₹60 + GST and our 100W flood light is ₹1,000 + GST, delivered across India.

Will I get a GST bill?

Yes. Every order comes with a proper GST invoice. Share your GST number so your business can claim input tax credit.

Which are the top 10 LED light brands in India?

Well-known LED light brands in India include Philips (Signify), Havells, Wipro, Syska, Bajaj, Crompton, Surya, Halonix, Polycab and Orient. For bulk and project buying, Diamond Electrical Industries, a Kolkata lighting brand trusted since 1958, sells direct at lower prices with a GST bill.
