Spirit Office

Why Spirit?

We’re experts – a small, specialist company that understand the principles of LEDs. All the design and modelling work is performed in house by our own specialist team. We don’t employ pushy salesmen – just technical people passionate about renewable energy who will provide you with a worthwhile, good value, LED lighting upgrade.


With Carbon Trust funding available for many SMEs, it is not uncommon for the payback time of LED upgrades to be under 2 years (no control upgrades), and under 4 years (with control upgrades).

Our Installations

  • Lighting Upgrade In Reading

    In July 2016, Spirit Solar Ltd upgraded the lighting of an office in Reading. This involved replacing fluorescent tubes with LED panels including daylight harvesting and dimming controls. The combination of controls and LEDs has drastically reduced the energy bills of the office, and the system is expected to pay for itself in 3 years.

    If the office was open from 7 am to 6 pm, 5 days a week for 252 days/year and 72W fluorescent tubes  were being replaced by 40W LED panels, assuming a price of 12p/kWh and there were a total of 50 lights, the savings will be:

    A saving of £10.64/year/light x 50 no. lights =  £532.22/year!

  • Slough Residential Block

    In Spring 2017, Spirit replaced the lighting in the communal areas of a residential building. Fluorescent and incandescent lights were replaced with energy efficient LEDs. This included IP65 rated LEDs for outdoor areas and PIR sensors to deliver maximum energy savings. Computer modelling was used to design the system and meet the legal minimum level of emergency lighting in the event of a power cut.

    This project also received Carbon Trust funding that along with reduced energy bills means the project should pay for itself in 3.5 years.

  • Reading Warehouse

    Spirit also upgraded the lighting of a warehouse in Reading during Spring 2017. This involved replacing high bay metal halide lights across the warehouse floor with 150W LED equivalents. The predicted annual kWh consumption of the lights at the warehouse fell by 69% with the installation of the LEDs. This large reduction in energy usage and bills gave the project a projected payback time of just 1.4 years.

    If the warehouse was open from 7 am to 6 pm, 5 days a week for 252 days/year and 400W high bay metal halide lights were being replaced by 150W LED high bays, assuming a price of 12p/kWh and there were a total of 50 lights, the savings will be:

    £83.16/year/light x 50 no. lights = £4158/year!
