The 50W LED Flood Light for Compounds and Parking

50 watt LED flood light: the short answer

A 50 watt LED flood light is sized for the space around a building: a bungalow compound, a society parking corner, a building entrance, a small godown yard or a terrace. As a common starting point it goes on a wall or short pole about 4 to 6 metres up, most often around 5 m, tilted down so its useful light reaches roughly 10 to 12 metres out from the wall.

It draws about 0.22 A at 230 V and, at typical LED efficiencies, gives somewhere around 4,000 to 5,000 lumens; the carton states the real figure. That is enough to light a compound well for walking, parking and security, and too much for a porch or a gate, where 10W to 15W will do.

Our VIYONA 50W flood light comes in two versions at one printed MRP of ₹1,450: the standard 1087 and the lens 1092. We make both at our works in Marol, Andheri East, Mumbai, packed 10 per box, and list a matching spare driver, the 1045, at ₹400.

Mounting height and coverage

Height decides how far a 50W spreads. At about 5 m on a house wall, tilted down, the lit patch runs from near the wall to roughly 12 m out, enough for a compound, a drive and two or three parked cars.

A 50W flood light at 5 m over a compound

Drawn by us to scale, as a rule of thumb rather than a lux calculation. The far edge should stop at your compound wall.

• Below 4 m: a hot spot near the wall and glare into eyes.
• 4 to 6 m: the usual range for 50W.
• Above 6 m: light spreads thin; a 100W is the better fit.

Aiming a 50W over a compound

At 5 m on a house wall, aim the centre of the beam about 6 to 8 m out, a little past the middle of a 12 m compound. The lower edge of the beam then lights the ground near the door, and the upper edge stops at the compound wall rather than going over it into the lane.

If the far half looks dim, tilt the fitting up a few degrees; if the light spills over the wall or into a neighbour’s window, tilt it down. Do this after dark, with someone at the switch, and check from the gate and from the road as well as from the house.

Where the compound wraps around a corner of the house, one 50W rarely reaches both sides. Put a second fitting on the side wall rather than angling one across the corner, which lights neither side well. Once the angle is right, tighten the bracket bolt fully; a loose fitting drifts in the first strong wind.

How much light is that? A worked example

Take a compound about 12 m by 12 m, about 144 sq m, lit by one 50W flood light. If the fitting gives about 90 lumens a watt (check the carton), it puts out about 4,500 lumens. Assume about half of that lands usefully on the compound; the rest falls outside or is lost.

As common practice, around 10 to 20 lux is comfortable for a compound or parking area at night. So one 50W suits a compound up to about 150 to 200 sq m; beyond that, add a second fitting or move up to 100W. Our guide to lumens vs watts explains the units.

Where a 50W flood light fits

• Bungalow or row house compound, lit from the house wall.
• Society parking corner of a few cars, from the building wall.
• Building entrance and drive, from above the main door.
• Small godown or workshop yard, from the shed wall.
• Terrace used for functions, from the stair-cabin wall.
• Not: a porch or gate; 10W to 15W is enough there.

The common thread is an area that starts at the foot of a building and runs out a few car lengths. For a gate or a porch at 2.5 to 3 m, our 10W and 15W Ultra Prime flood lights do the job; for a factory yard or a building front, step up to 100W. A 50W sits between: big enough to light the ground around a house or a small business, small enough not to flood the neighbours if it is aimed well.

For lighting around a house in general, including wall and gate lights, see outdoor lights for home.

50W flood light price

Both our 50W codes are printed at ₹1,450. Against the wattages either side:

The step down to 30W saves ₹350; the step up to 100W costs ₹500 more. A box of ten 1087 fittings is ₹14,500 at MRP. The full range is on our flood light manufacturer page.

Standard or lens at 50W?

At 50W, most jobs want the standard 1087. A compound, a parking corner or a yard starts right below the light, and a wide beam covers it evenly from 4 to 6 m.

The lens 1092 makes sense at 50W when the light has a target away from it: a signboard lit from below, a name board on a building front, or the far end of a long, narrow drive. There, a narrower beam, which lens optics usually give, puts more light on the target and less on the ground in between; ask us for the beam angle of the 1092 first.

Since both cost ₹1,450, choose by the job, and write standard or lens on the order. Our lens flood light guide shows the two beams side by side.

One 50W, two 50W or one 100W?

For a compound larger than one 50W can cover, there are two routes:

• Two 50W on two walls: ₹2,900, light from two sides, fewer shadows behind cars.
• One 100W higher up: ₹1,950, one bracket and one cable run, but one fitting must be 6 m or more up.

One 100W is ₹950 cheaper on the fittings. Two 50W fittings win where there is no high mounting point, where cars or trees would cast long shadows from one light, or where the area is L-shaped around a building. For a big square yard with a tall wall, see our 100 watt flood light page.

Wiring and switching a 50W

At about 0.22 A, a 50W flood light is a light load. It can share a lighting circuit, controlled by an ordinary one-way switch on the phase, placed indoors near the door. Protect the circuit with an RCCB (30 mA earth-leakage breaker) as well as the MCB, as for any outdoor light. A timer or a motion sensor in the same phase line suits a security light, provided its rating suits the fitting.

• Phase through the switch; neutral direct; earth to the metal body.
• Joint in a weatherproof junction box with a tight gland and a drip loop.

Our flood light installation guide covers the steps; the circuit protection is in our guide to the 6 amp MCB.

Running cost of a 50W

Left on for about 12 hours a night, a 50W flood light uses 0.6 units a night, about 219 units a year. With a motion sensor that lights it only when someone walks in, the hours, and the units, drop sharply.

Most homes do not need a 50W burning all night. A common setup is a small 10W or 15W light on the gate all night, and the 50W on a sensor or a switch for when a car comes in or someone is outside. That keeps the compound safe and the bill small.

Spare driver and bracket

Our spare driver for the 50W is the 1045, listed for 50W at ₹400. Our catalogue prints IS 15885 (Part 2/Sec 13) and registration R-71026310 in its driver section; ask us for the registration of the 1045. If a 50W flood light fails after some years, the driver is the usual cause; changing it costs far less than a new fitting.

We list two wall mounting brackets, the 1082 at ₹90 and the big 1083 at ₹180. Ask your dealer which suits the 50W housing, and fix it into solid masonry, not plaster. The bracket product page shows both.

Our catalogue does not print an IP rating for the flood lights; for a fully exposed wall, ask for the rating of the exact code. See IP rating for lights.

Mistakes people make at 50W

• 50W on the gate: glare into the street; use 10W to 15W there.
• Fitted at 3 m: a blinding hot spot at the door, dark at the far end.
• Aimed straight out: lights the building across the lane, not your compound.
• On all night: 219 units a year where a sensor would do.
• Taped joint: water gets in at the first monsoon.

Each of these is a placement or wiring mistake, not a fault in the fitting. Fix the height and the tilt first; they decide whether a 50W lights your compound or the neighbours’ windows.
