Lumo integrates real-time sun and shade data via SunSeekr partnership

# What happened Lumo has partnered with sun-mapping platform SunSeekr to add real-time sun and shade data to its national network of digital billboards. The integration produces a continuous solar profile for every Lumo location, showing sun angle, direct exposure, shade transitions and the hours a screen sits in direct sunlight.

# Why it matters

# How advertisers can use it The partnership, called "Sunshine State," exposes sunlight signals for dynamic creative optimisation (DCO) and custom event triggers in programmatic deals. Examples of concrete rules buyers can set:

• Serve a lens-focused eyewear creative only while a screen is in direct sun.
• Shift a beer creative to daytime-sun variants or weight delivery toward the hour before sunset.
• Pause or hold spend when a site is in shade, or trigger a terrace or hospitality message when nearby venues are bathed in afternoon sun.

Those rules can be tied to individual screens, not to a single weather feed across a whole city.

# Data and commercial context SunSeekr launched in London in 2025 and has grown to more than 350,000 users, reaching number one in the UK App Store Lifestyle category. Its sunlight technology has been used commercially by brands, including an example noted for connecting consumers with sunny hospitality venues.

Lumo's general manager of platforms and partnerships, Jack Plowright, said the value is the specificity of the data and DOOH's performance when it responds to contextual moments. SunSeekr founder and CEO Mo Dawod said sunlight changes behaviour—where people walk, sit and stop for a drink—and that SunSeekr's modelling captures that on-the-ground effect better than a weather forecast alone.

# Operational and sustainability implications Ambient light levels drive screen brightness and that, in turn, drives energy use. High ambient light requires higher brightness to keep content legible, which raises power draw. By knowing the solar conditions for each site, Lumo can model the relationship between sunlight and operational energy demand more accurately and report improved energy usage and emissions figures to advertisers.

# What this enables going forward The integration enables more precise contextual targeting for DOOH campaigns and gives advertisers a concrete signal they can program against. It also feeds sustainability reporting: advertisers get clearer data on the emissions consequences of running bright content on sunlit screens. Those two outcomes address commercial performance and environmental transparency at the screen level.

# Bottom line
