Warehouse, Factory & Godown Lighting

Up to 5 m use 50W or 60W with a 90° narrow beam. From 5 to 7 m use 100W. From 7 to 8 m use 120W. From 7 to 10 m use 150W. From 10 to 14 m use 180W or 200W. Measure to the underside of the truss, not the roof peak - in a pitched shed the two can differ by several metres.

One to one and a half times the mounting height. Fixtures at 8 m sit 8 to 12 m apart, at 12 m they sit 12 to 18 m apart. Wider spacing produces bright pools with visibly darker floor between, which workers experience as darker overall than even light at a lower level.

Because the beam angle is too wide for the racking. A 120° beam over tall racking in narrow aisles lights the tops of the racks, and the racking itself blocks light from reaching the floor. Fix it by running a line of fixtures down each aisle rather than a grid across the building, or by using narrower optics.

Replacing a 400W metal halide with a 150W LED saves around 900 units per fixture per year at 12 hours a day. Across 20 fixtures that's roughly 18,000 units - about ₹1.44 lakh annually at ₹8 per unit, which usually exceeds the cost of the fixtures and gives payback inside the first year.

Roughly a 400W metal halide, at 15,000 lumens. Beyond the energy saving, LED reaches full brightness instantly rather than taking minutes to warm up, restrikes immediately after a power cut, and holds its output and colour over life instead of degrading and yellowing.

Same lumens at the same wattage, different construction. Reflector is the conventional aluminium cone. UFO Pro has a heavier housing with more heat sink area for multi-shift duty in hot sheds. Slim gives the same output at a fraction of the weight - 660 g at 100W - which matters for light roof structures, single-person installation and freight cost on large orders.

90° for lower ceilings and for tall racking with narrow aisles, where light needs to reach the floor rather than the tops of the racks. 120° for open floor - production, assembly, packing and showrooms - where even coverage matters more than penetration.

Because the dust rating matters indoors. Indian industrial environments generate grinding dust, textile lint, cement, grain and packaging fibre, and anything entering a fixture settles on the driver and LED board, blocks heat dissipation and shortens life. A sealed fixture is what keeps a high bay working in year four.

High bays under the canopy where there's a roof, and 200W flood lights on the building wall angled outward where there isn't. For open yard and container areas, 100W or 200W floods one every 10 to 15 m with overlapping beams. For internal roads, 100W or 150W street lights on poles rather than floods.

Use 180W or 200W fixtures for 10 to 14 m, and suspend them rather than surface-mounting where possible - dropping fixtures 1.5 m below a 12 m roof effectively makes it a 10.5 m installation and improves floor-level light without changing the fixture. It also makes future maintenance reachable from a lower lift.

Almost always the driver, not the LEDs. Industrial supply is harsh - motors starting put spikes on the line, restoration after a cut delivers a surge, and welding sets are brutal on shared circuits. A wide 90-265V input, a die-cast heat sink and a surge protection device at the panel are what prevent it.

It's the wrong shape for the job. A flood light throws light outward at an angle, which indoors puts glare directly into workers' eyes and wastes output on the walls. High bays point straight down and are designed for ceiling mounting. Keep flood lights for the yard, loading bay and open areas.

The standard models are not. Where a facility needs dimming or daylight linking, say so at quotation stage - the driver specification changes and it has to be built in rather than added afterwards.

Yes. Warehouse and factory orders are project quantity, quoted at project pricing with GST invoicing - which matters for depreciation and input credit. We're BIS certified and government empanelled, manufacturing in Delhi and shipping PAN India.

Yes, and it's worth doing before ordering. Send shed dimensions, ceiling height, racking positions and aisle widths, what happens in the space and your shift pattern. We'll return a fixture count, wattage, spacing and layout rather than you estimating from square footage.
