How much could your lighting save?
Model individual areas and compare your existing installation with a planned LED solution. All values are adjustable. Prefilled figures are an example, not a quotation.
1 / Lighting areas
Include ballast or LED-driver power. Both options use the same operating schedule. Only add control savings if their effect is not already included in the hours.
How the comparison works
Consumption = quantity × system power (W) × hours/day × days/year ÷ 1,000. The control factor reduces LED consumption only. Annual operating costs = electricity + maintenance.
Maintenance stays nominally constant; electricity price changes apply from year 2. Payback is the first calculated cost crossover within the period, interpolated linearly within the year. Net present value discounts year-end savings and subtracts net investment. Grants are assumed received at the start.
This is not a lighting calculation or funding approval. Equivalent suitable lighting quality must be verified separately. Financing, taxes, residual values, replacement investments, standby power and heating/cooling interactions are excluded. Assess replacement requirements separately for long periods.

A few photos, existing luminaire types and operating hours are a good starting point. We will discuss a renovation that suits your building, budget and goals.
