LED displays in Butwal and Bhairahawa

Why are Butwal and Bhairahawa good locations for DOOH?

Butwal and Bhairahawa are strong DOOH locations because large volumes of traffic pass through a small number of junctions. Butwal sits where the hill road from Pokhara meets the plains and the East–West Highway, and Bhairahawa links to the Sunauli border crossing, Lumbini and the international airport.

That concentrates attention. A screen at the right junction is seen by local commuters, long-distance buses, freight drivers and visitors in a single day, which suits advertisers with regional reach — banks, telecoms, vehicles, education and consumer brands.

Our installation at Lakhan Thapa Chowk in Butwal, operated by Universal Advertising Pvt Ltd, is a Lampro LDT P8 outdoor screen at a junction site — a typical format for this kind of location.

Which pixel pitch suits junction and highway sites?

Junction and highway screens in Butwal and Bhairahawa are usually read from 8 to 20 metres or more, so P8 to P10 is generally the right range. The guiding rule is that pitch in millimetres roughly equals the closest comfortable viewing distance in metres, and at a busy chowk the nearest regular viewer is often across the carriageway.

A coarser pitch also has practical benefits on these sites. Larger pixel spacing means fewer LEDs per square metre, which lowers the cost of a large screen and its power draw, and lets you afford a bigger face that is legible from further away.

Retail, bank and restaurant screens at street level are a different case: viewers stand a few metres away, so P3 to P4 outdoor, or a fine-pitch indoor screen behind glass, is more appropriate.

How do heat and dust affect screens here?

Pre-monsoon heat in the western Terai is a real stress on LED screens, and it must be handled through cabinet design, ventilation and brightness control. LEDs, driver ICs and power supplies all age faster when they run hot, and a screen in direct afternoon sun on a dark steel structure can get very hot inside.

The answers are cabinets designed for outdoor thermal loads, a structure that leaves air space behind the screen, and in larger installations forced ventilation or cooling in an enclosed service area. Automatic brightness control helps too: a screen does not need full output at dusk, and reducing it cuts heat and power together.

Dust from heavy traffic settles on module faces and in vents. A regular cleaning schedule, written into the service plan, keeps brightness even and air flowing.

What about the monsoon and humidity?

The monsoon in the Terai brings heavy rain and long periods of high humidity, so IP65 sealing on both front and rear is essential. A front-only rating leaves the rear electronics — power supplies and receiving cards — exposed to rain and condensation.

Drainage around the structure matters on flat plains sites where water can pool. Electrical connections should sit above any likely standing water, with cable glands and drip loops to keep water out of cabinet entries.

Running the screen every day, even at low brightness, helps keep the internals warm and dry through the wettest weeks.

How should power be protected in Butwal and Bhairahawa?

Every outdoor screen here should have a stabiliser or UPS, surge protection and proper earthing. Industrial loads, long distribution lines and storms all contribute to voltage swings and spikes, which shorten the life of LED power supplies.

Lightning protection deserves specific attention for tall, exposed structures on flat land. The structure should be earthed and the incoming supply protected, and both should be checked during the site survey.

Large DOOH screens draw significant power at full brightness, so the supply capacity at the site must be confirmed early. Upgrading a connection after the steel is up is slower and more disruptive than planning it first.

How do installation, service and approvals work?

We install in Butwal and Bhairahawa with our own team, after a free site survey that confirms structure, access, power and orientation. A standard outdoor screen takes two to three days on site including structure; large billboards or complex mounting take five to seven.

Displays carry a two-year manufacturer warranty honoured locally, with spares held in Kathmandu. For DOOH operators in particular we recommend keeping batch-matched spare modules and a power supply on site, so a dark patch on a paid advertising face can be fixed the same day.

Outdoor screens generally involve the sub-metropolitan or municipal office and the ward. Requirements vary and change, so confirm them with the municipality and ward office before committing to a site or a lease.
