“Fantastic from start to finish. 19 sockets, bathroom fans and more — they barely left a mark in the house. Polite, professional and lovely to have in my home. Would absolutely recommend anytime.”

// About This Service //
Smarter Lighting — Lower Costs Across Cork
Haven Electrical carry out LED lighting upgrades for commercial premises across Cork City and County — offices, retail units, restaurants, schools, and any building still running on fluorescent, halogen, or HID lighting. We assess your existing lighting, calculate the energy savings available from an LED upgrade, and carry out the installation with minimum disruption to your operations. LED upgrades are one of the fastest-payback electrical improvements available to any commercial premises — most Cork offices and retail units achieve payback within 2–3 years. All upgrade work is RECI certified.
Energy Savings Calculated
We calculate projected annual energy savings for your specific installation before you commit to the upgrade.
Minimal Disruption
Most office and retail LED upgrades can be phased to minimise downtime. Evening and weekend work available.
RECI Certified
All LED lighting upgrade installations RECI certified on completion.
Controls Included
Occupancy sensors, daylight sensors, and dimming controls included where they add value.

Why Cork Businesses Choose Haven Electrical
Honest Savings Projections
We calculate savings based on your actual metered consumption — not inflated marketing figures. The payback period we quote is real.
Right Fitting for the Space
Not all LEDs are equal. We specify fittings with the correct colour temperature, beam angle, CRI, and driver quality for each application — office lighting needs different treatment to retail or hospitality.
Complete Package
We remove the old fittings, install the new ones, update the wiring where needed, and certify the work. One contractor, no loose ends.
Phased Delivery
Most office and retail upgrades can be done in phases — floor by floor or area by area — to avoid closing down your operations for the duration.

LED Lighting Upgrades FAQs
The savings depend on what you’re replacing, how many hours you operate, and your electricity tariff. LED office panels use approximately 30–40W versus 50–60W for the fluorescent equivalents they replace. For a typical Cork office with 100 fluorescent panels running 10 hours per day, 250 days per year at €0.20/kWh, the saving is around €2,500 per year. For retail premises with track lighting or halogen spotlights, the savings can be substantially higher — LEDs replace 50W halogens with 7W equivalents. We calculate the specific savings for your premises during the survey.
Most commercial LED upgrades in Cork achieve payback in 2–4 years, after which the energy savings are pure reduction in electricity bills. For premises with high operating hours (retail, hospitality, care homes) or high-wattage existing lighting (halogens, HID), payback can be as short as 1–2 years. We calculate the payback period for your specific installation as part of the survey and quotation.
Fluorescent recessed panels (typically 600x600mm or 1200x300mm) are replaced with LED equivalents. For a standard 60W 4-tube fluorescent panel, the LED equivalent is typically 36–40W while delivering the same or better illuminance. We specify fittings from commercial-grade manufacturers rather than budget imports — the driver quality and LED chip quality determine the actual service life and light output over time, not just the initial specification.
Yes — occupancy sensors, daylight sensors, and DALI or 0-10V dimming controls can be integrated into the lighting upgrade. Occupancy sensors in corridors, toilets, and meeting rooms that automatically switch off when the space is unoccupied can add a further 20–30% to the energy savings. We recommend and specify controls where they add real value, not as an upsell on every job.
In most cases, LED fittings can be connected to the existing fluorescent wiring with only minor modifications (removing the ballast and starter). For T8 and T5 fluorescent replacements using LED tubes, some wiring modifications are required depending on the LED tube type. We assess the existing wiring as part of the survey and flag any wiring modifications needed in the quotation.
Colour temperature (measured in Kelvin) affects how the light looks and feels: 3000K is warm white, similar to halogen; 4000K is cool white, the standard for offices and retail; 5000–6500K is daylight, used in some retail and clean-room environments. For Cork offices, 4000K LED panels are the most common choice. For retail, the choice depends on the products being displayed — warmer light works better for food and clothing; cooler light for technical or fashion retail. We advise on the correct temperature for each application.
Yes — phased upgrades are common. We can start with the highest-energy-use areas (open plan offices, production floors, car parks) and phase the remaining areas over subsequent years. Phasing allows you to spread the capital cost and manage cash flow. We can prioritise areas by energy saving potential to maximise the payback on each phase.
The rated life of commercial LED fittings (typically 50,000–70,000 hours) is based on L70 — the point at which the light output has degraded to 70% of the initial value. This means LEDs don’t simply fail at end of life — they gradually dim. For quality commercial LED fittings with good driver design, service lives of 10–15 years are realistic for normal commercial operating hours. Budget LED fittings with poor drivers fail much earlier. We specify fittings from manufacturers with genuine warranty programmes and track records.
