Illumination
Also called FrontlitBacklitNon-litLighting
Illumination is how an outdoor advertising panel is lit after dark: frontlit, where fixtures mounted in front throw light onto the printed face; backlit, where light sits behind a translucent material and passes through it; or non-lit, where the panel is dark once daylight goes.
In more detail
Illumination is almost always a separate commercial line from the media, and a non-lit panel and a lit one on the same structure are different products at different prices. On a plan quoted without it specified, assume nothing.
The distinction between frontlit and backlit is not cosmetic. Frontlit is external floodlighting onto an ordinary printed face: cheaper, simpler, and dependent on the fixtures being aimed properly and actually switched on. Backlit puts the light source behind a translucent substrate so the panel glows evenly, which reads considerably better at night and holds colour, but costs more to build, to print for and to run.
The decision that actually matters is whether the audience is there after dark at all. A panel on an office commute corridor that empties by eight is paying for illumination that reaches very few people. A panel on a market approach, a restaurant strip, a station road or an entertainment belt is doing half its work after sunset, and buying it non-lit throws that half away.
- 01
What is the difference between frontlit and backlit?
Where the light sits. Frontlit means fixtures in front of the panel throwing light onto the printed surface. Backlit means the light is behind a translucent material and shines through it.
Backlit looks materially better at night — even, saturated, no hot spots or shadowed corners — and it needs a different substrate, so the print specification changes too. Frontlit is cheaper and perfectly adequate where the fixtures are properly aimed and maintained, which is the part worth checking rather than assuming.
- 02
Is illumination included in the hoarding rate?
Usually not, and this is one of the more common surprises on a first outdoor invoice. Illumination is typically quoted separately, and in some arrangements the running electricity is billed separately again.
Ask three things at the proposal stage: whether the position is lit, what type, and who pays for the power. A panel described as illuminated whose fixtures are not switched on is a non-lit panel at a lit price.
- 03
When is a non-lit panel the right choice?
Where the audience genuinely is not there after dark. A daytime commercial corridor, an office belt, an industrial approach, a highway stretch with little night traffic — on these, paying for illumination is paying for hours nobody is present.
It is also a reasonable trade when the budget forces a choice between fewer lit positions and more unlit ones in a catchment where frequency matters more than night presence. That is a real decision worth making deliberately rather than defaulting either way.
Where it earns its place
- Market approaches, restaurant and entertainment belts, station and terminal roads — anywhere the crowd is present after sunset.
- Festival and wedding-season windows, when evening activity is at its highest in most Indian markets.
- Winter months in northern India, where darkness falls early and the evening commute happens in it.
- Any position where the brand's competitors are lit and it would otherwise be the dark panel on the row.
And where it does not
Illumination on a corridor that empties after office hours is money spent on an absent audience, and the same budget usually buys more useful frequency elsewhere. It is also worth nothing if it is not maintained — a frontlit panel with two failed fixtures reads worse at night than a clean unlit one, and nobody will tell you unless somebody is checking. If illumination is being paid for, night monitoring photographs should be part of the deliverable.
What moves the price
The variables, not a rate.
We do not publish a rate card. We own no media, so every plan is negotiated against several vendors — a published figure would describe what we would like to charge rather than what the market will take.
- 01Frontlit, backlit or non-lit — three different products, not three settings.
- 02Whether the running electricity is included or billed separately.
- 03The substrate, since backlit needs translucent material and a different print specification.
- 04Hours of illumination and whether they are contracted or assumed.
- 05Maintenance of the fixtures over the cycle, and who is responsible for a failure.
Questions we are actually asked
Illumination, in practice.
Does a lit hoarding cost more than an unlit one?
+
Yes, usually on more than one line — the illumination itself, sometimes the electricity, and on backlit positions the substrate and printing as well. Whether it is worth it depends entirely on whether your audience is on that road after dark.
How do I know the lights were actually on?
+
Night monitoring photographs, dated and geotagged, on a schedule rather than only at mounting. If a plan is paying for illumination and only carries daytime proof, it is not proving the thing it is paying for.
Is backlit always better than frontlit?
+
Better looking at night, yes. Better value, not always — a well-aimed and properly maintained frontlit panel does the job on most corridors, and the money saved often buys another position. Backlit earns its premium where the panel is close, read at length, and sits among other lit displays it has to compete with.

- Hoarding
A hoarding is the Indian term for a large-format outdoor advertising panel — a printed or digital display mounted on a fixed structure beside a road, on a rooftop or on a boundary wall, sold for a defined period rather than by the number of people who pass it.
- Unipole
A unipole is an outdoor advertising display carried on a single vertical column, so the panel stands clear above the traffic with nothing supporting it from the sides — as distinct from a hoarding on a lattice frame or one fixed to a wall or roof.
- Flexing and Mounting
Flexing is printing a campaign onto flex — the coated PVC sheet most Indian outdoor advertising is printed on — and mounting is fitting the printed sheet to the structure.
- Monitoring Photographs
Monitoring photographs are dated, geotagged photographs of each booked position, taken at mounting and again during the campaign, that evidence the advertisement was actually displayed at the site contracted for the period contracted.
