LED Upgrading That’s CashFlow Positive on Day One

Zero Maintenance

With all maintenance covered in the service, you eliminate 100% of the cost of lamp and driver replacements, maintenance personnel, and inventory management.  Our industry-leading quality standards and 24-hour field teams ensures minimal disruption and same-day replacements.

After a service period of five years, the entire system is yours to keep with no further obligation, netting additional savings for several more years. FAQs >

We offer two models;  Upgrading Existing Facilities, and New Construction


We survey your current lighting and match each lamp and fixture with a NIPPON LED counterpart one for one.

To determine the savings, we install an onsite mockup and take meter readings before and after the upgrade. The savings model is used as the basis for your service agreement.  All at no cost to you.

Ideal customers have at least S$4,000 in monthly energy costs and operate lights on a fixed schedule for 18 to 24 hours every day. Manufacturing and logistics facilities, hotel and office corridors, car parks, and staircases offer major savings.  

If you have recently upgraded your facilities with commercial-grade LED lights, you may be disappointed with the lack of savings or high percentage of defects. Our investment-grade NIPPON LED lights and save up to an additional 20% in energy costs compared to the leading LED brands in Singapore, and have a five-year warranty against loss of luminance and color shift.

If your project is in the design stage and LEDs are not currently specified, we propose LED lighting to replace your current specifications and calculate the savings.  The service agreement is based on the simulated energy savings. This allows you to completely eliminate your budgets for installation and ongoing maintenance.

If you already have LED lighting specified, in most cases our models are up to 20% more efficient. With a Centropi service agreement, you eliminate your maintenance budget while still enjoying significant energy savings.

Frequently Asked Questions

What does “zero-cost” upgrading really cost?
Exactly as promised.  The customer has no capital expenditure and is never charged for anything other than the fixed monthly service charge.  We cover 100% of the cost to analyse, customise, test, install, and service the lighting systems.  Our service charge is only a portion of the monthly energy cost savings associated with the upgrade during a 5-year service contract.

How is the savings calculated?
For existing spaces, we monitor current usage and install mockups for comparison studies, typically for a week. Most customers have continuous and fixed operating schedules, so short mockups allow us to accurately calculate savings and eliminates the need for ongoing monitoring and energy usage audits.

The results of these studies determine the fixed monthly fee for the duration of the contract.

What if the facilities are renovated during the contract period?If during the contract a renovation drastically increases the usage pattern and new fixtures are installed, we can fit out this new area and incorporate it into an amended or separate service agreement.  If no new fixtures are installed and only usage increases, there is no change in our fee. If usage is drastically reduced though removal of lighting fixtures, there is an option to buy out the portion of the contract effected at 80% of the remaining value.  In most renovations lamps are relocated to the new area and usage is not significantly effected.

Why are your products superior to the competition’s?
As an investment-grade brand, our NIPPON LED engineers and designers are continuously evolving the product line with the latest technologies to keep ahead of a very competitive Japanese commercial LED market. Our over-engineered drivers are paired with the world’s best chips for superior efficiency, reliability, and durability.

Further, our factories are under a strict quality assurance regime that includes running every lamp and fixture for 24 hours before shipping.  With more than 6 million lamps under contract across Japan, keeping our defect rate below 1% is critical to our business model.  

Is the CENTROPI service feasible for new projects?
For projects in design or in construction phase, we analyse the current lightings specifications and propose a complete upgrade with our LED fixtures and controls.  Even commercial-grade LEDs can be upgraded to NIPPON LEDs with savings of up to 20%. The savings are modelled using the product parameters and verified by the client's consultants.  The monthly fee is based on these modelled savings.

What if the property is divested during the service contract period?
In the case that a property is divested during the contract period, the contract is transferable, and we give the option to buy out the contract at 80% of the remaining value.
