How to choose an LED street light manufacturer in Noida and Delhi NCR
Delhi NCR has hundreds of companies selling LED street lights. Far fewer actually build them. For a municipal body, a PSU township or a contractor bidding on a PWD road package, the difference shows up two monsoons later, when drivers start failing and the supplier cannot be traced. This guide sets out what to check, in the order a procurement engineer would check it.
1. Confirm you are dealing with a manufacturer
A large share of luminaires sold in the region are imported housings assembled or simply relabelled locally. That is not automatically a problem, but it changes who stands behind the product. Ask three direct questions: where the housing is made, where the driver is assembled, and where final testing happens. A manufacturer will answer with an address and offer a factory visit. For buyers in Noida, Greater Noida, Ghaziabad, Gurugram and Delhi, a visit to a unit in Sector 63 or the Phase II industrial belt takes an afternoon and tells you more than any brochure.
Look at what you see on the floor: die casting or fabrication of the housing, driver assembly, burn-in racks where fittings run for hours before dispatch, and a photometry or at least a lux measurement setup. A trading office with a sample cupboard is a trader.
2. Check the BIS registration, not just the logo
LED luminaires sold in India fall under the BIS Compulsory Registration Scheme. A street light should carry a registration number in the form R- followed by eight digits, printed with the relevant Indian Standard, typically IS 10322 (Part 5/Section 3) for road and street lighting luminaires. The important check is that the registration is in the name of the brand on the fitting and covers the model you are buying. You can search the number on the BIS CRS portal in a couple of minutes. Our guide to BIS certification for LED lights walks through that search step by step.
3. Read the datasheet the right way
Datasheets are written to impress, so read the figures that matter and ignore the rest.
- System efficacy, not chip efficacy. A chip rated at 180 lm/W can end up as a 110 lm/W luminaire once driver and optical losses are counted. Tenders should, and usually do, specify lumens per watt at luminaire level.
- Surge protection. Street lights sit at the end of long overhead feeders and see lightning induced surges. Many municipal and PWD specifications ask for 10 kV surge protection in the fitting. Check whether the protection is inside the driver or a separate SPD, and whether it is replaceable.
- Power factor and harmonics. A power factor above 0.95 and total harmonic distortion under 10 percent are common requirements, and they matter when hundreds of fittings share one feeder.
- Ingress and impact. IP66 for the optical and driver compartments, and an IK rating for the lens if the fittings are at vandal height.
- Operating voltage window. Grid voltage on rural and peri-urban feeders swings widely. A driver that runs from roughly 140 to 270 V AC keeps the lights on through the swings.
4. Match the optics to the road
Wattage is the wrong starting point. The road dictates the lighting class, and IS 1944 sets out classes from major traffic routes down to residential streets, each with an average illuminance and a uniformity requirement. A good supplier will ask for the carriageway width, pole height, spacing and arm length, and return a photometric layout showing that the chosen fitting meets the class. A 60 W fitting with the right asymmetric optic often outperforms a 90 W fitting with a generic lens, because the light lands on the road instead of the neighbouring buildings.
| Road type | Typical mounting height | What to ask the supplier for |
|---|---|---|
| Arterial road or highway | 9 to 12 m | Photometric layout to the IS 1944 class, spacing to height ratio, glare control |
| Colony and township roads | 6 to 8 m | Uniformity across the carriageway, spill control near houses |
| Industrial estate roads | 8 to 10 m | Surge rating, IK rating, spare driver availability |
| Junctions and roundabouts | 12 m and above, or high mast | A combined layout, often with a high mast at the centre |
5. Ask for the delivery record
For government work, a supplier's history of completed orders is the most honest reference available. Ask for purchase orders and completion certificates from comparable projects, and call one of the buyers. A supplier registered on the Government e-Marketplace (GeM) also carries a public rating built from past buyer feedback, which is worth reading before you shortlist.
6. Think about the pole and the foundation
Luminaires fail for their own reasons, but poles fail because of corrosion and poor foundations. Octagonal poles should be hot dip galvanised to a stated coating thickness, with the base plate and foundation bolts designed for the local wind zone. Buying poles and luminaires from the same manufacturer keeps arm lengths, spigot sizes and mounting details consistent, which removes a whole class of site problems.
