What an LED wall costs to own

The invoice is not the cost

An LED wall is quoted as a single number and lived with for a decade. Between those two facts sits everything this guide is about: the electricity it burns every hour it is on, the modules and cards that fail and get swapped, the spares you should have bought at the start, and the slow dimming that eventually ends its useful life.

For a wall running long hours, electricity alone routinely reaches 40% of the five-year total — more than every maintenance activity combined. It is also the most predictable component, because it follows directly from specs the datasheet already gives you.

Total cost of ownership is not a precise science; it is a set of defensible assumptions. What matters is that the assumptions are visible and adjustable, which is why every default in the calculator can be overridden.

Energy: average power, not maximum

Use average power for energy and maximum power for electrics. Maximum is the full-white worst case that decides breakers and cable; average is the content-mix figure, typically 30–40% of maximum, and it is what actually accumulates on the meter.

Multiply the wall's average watts by the hours it is genuinely on. This is where estimates most often go wrong: a retail wall on 16 hours a day for 365 days runs 5,840 hours a year, while a boardroom wall on 8 hours for 250 working days runs 2,000 — nearly three times less energy for identical hardware.

annual kWh = cabinets x average W / 1000 x hours per day x days per year

Maintenance: a percentage, honestly labelled

Nobody can tell you exactly which receiving card will fail in year three. The industry plans maintenance as a percentage of hardware cost per year, and that convention is used here rather than an invented model of visits and hourly rates.

Around 2% a year suits a serviced fixed installation: module swaps, receiving cards, fans, power supplies and periodic recalibration. Rental and touring stock lives a much harder life — trucked, rigged, derigged, occasionally dropped — and 5% is the safer planning figure. Your own service contract beats both numbers, and the calculator takes whatever you enter.

Front-serviceable cabinets matter more than the percentage suggests. A wall installed against a structure with rear-only access can require scaffolding or a lift for a single dead module, which turns a fifteen-minute swap into a scheduled job.

Spares belong in the purchase order

LEDs are sorted at manufacture into bins by colour and brightness, and those bins drift between production runs. A cabinet bought two years after the wall will very likely not match it, even when the model number is identical.

The fix is boring and effective: buy roughly 5% spares with the original order, from the same batch. On a 12-cabinet wall that is one cabinet. It is far cheaper than a visibly mismatched patch in the middle of a display, and it is the reason spares sit in the capital budget rather than the repair budget.

Service life is hours, not years

Datasheets quote 100,000 hours almost universally. That figure is L50: the point at which the LEDs have dimmed to half their original brightness. It is not a failure point — the wall keeps working, it just gets dimmer and harder to colour-match against anything newer.

What converts those hours into years is entirely your duty cycle. At 16 hours a day, 100,000 hours is about 17 years. Running 24/7, the same wall reaches half brightness in under 12. A wall that is only on for events may never reach it before it is replaced for other reasons.

service life in years = lifetime hours / (hours per day x days per year)

A worked example

Twelve 500 x 500 mm cabinets — a 3 m2 wall — at 150 W average, running 16 hours a day all year, at EUR 0.30/kWh, hardware quoted at EUR 18,000, costed over five years.

The wall averages 1,800 W across 5,840 on-hours: 10,512 kWh a year, or EUR 3,154 annually and EUR 15,768 over the term. Maintenance at 2% adds EUR 360 a year. A 5% spares provision buys one cabinet at EUR 1,500.

Total five-year cost of ownership: EUR 37,068 — about EUR 7,414 a year, or EUR 2,471 per square metre per year. Electricity is 43% of that total, and 83% of everything spent after the invoice. Halving the operating hours would save more than the entire five-year maintenance budget.
