In the ongoing quest for sustainability and energy efficiency, companies worldwide are taking steps to reduce their carbon footprint and save costs. One impactful and cost-effective measure a company can take is to upgrade lighting systems to energy-efficient LED lamps. inepro has recently made such a transition, which not only highlights environmental responsibility but also provides financial benefits.

The transition to more energy-efficient LED lamps

inepro recently decided to replace its old LED lighting systems with new, energy-efficient LED lamps. The new lamps not only offer brighter light, but are also more energy-efficient, with an impressive light output of 60 lumens per watt more than the old lamps. This transition has not only provided improved lighting in inepro’s facilities, but has also resulted in significant energy savings.

Impressive energy savings

One striking result of this transition is the significant energy savings inepro has managed to achieve. The new LED lamps allow the same light output to be achieved with fewer lamps (-72 lamps), resulting in savings of no less than 6026 kilowatt-hours (kW/h) per year, representing a 40% energy saving. These figures not only underline the impact of the transition, but also show how smart choices can lead to greener and more sustainable operations.

The calculation below preceded this.

Previous situation

The previous tubes gave about 90 lumens/W (CRI 80) when new.
At the time of replacement, the tubes no longer reached that lumen output due to their age. This calculation still assumes the new state because we want to achieve the initial light level in the new situation.

New situation

The new tubes give 150 lumens/W (CRI* 95) in new condition.
This is relatively low because there are also tubes that deliver 180 and sometimes even 200 lumen/W. The reason why inepro does not choose tubes with higher lumens has to do with the ‘light output and pleasant light’ ratio.

Calculation

Existing tubes
90 l/W x 27W = 2430 lumens per tube, 180 tubes x 2430 lumens = 437400 lumens

New tubes
150 l/W x 27W = 4050 lumens per tube, 180 tubes x 4050 lumens = 729000 lumens
This also means that you can create the same amount of light with fewer tubes:
437400 lumens / 4050 lumens = 108 tubes

Conclusion

If 108 tubes are tactically placed, the result is identical light output.
Because the light is of better quality, almost ‘full spectrum’ as it is called, people will experience it as soft light and will have better visibility at a light color of 4000K.

Existing: 180 x 27W = 4860W
New: 108 x 27W = -2916W
Saving: 1944W

This saving adds up to a good 2000W. That’s 2 kWh saved every hour.
1944W/h x ~3100h.* = 6026400W = 6026 kWh annualized savings.

*…CRI = Color Rendering Index
** 12h. x 5d. x 52 w.
= 3120h./yr.

A step towards sustainability

This transition to more economical LED lamps is more than just a technological upgrade. It represents a serious step by inepro towards sustainability and environmental awareness. By reducing its energy consumption and carbon footprint, inepro is contributing to a greener future and demonstrating its commitment to corporate responsibility.

Well-being and light: more than just seeing

Lighting not only affects what we see, but also how we feel. A well-lit workplace can reduce fatigue and improve overall well-being. It’s not just about physical health, but also mental well-being. The right lighting can reduce stress, improve moods and contribute to a healthier working environment.

‘Natural light’ or ‘pleasant light’ is indicated in CRI (Colour Rendering Index). This value has a scale from 0 to 100% with 100 being the most natural light. The higher the CRI value the lower the light output. The higher the CRI value the more pleasant the light. An additional advantage of a high CRI value is that one perceives more with less light. This is due to better color rendering, better contrasts and more perceptible nuance differences. People working under this light will feel more comfortable and tire less easily. inepro’s new lighting has a CRI value of 95 and therefore feels extremely pleasant and natural.

Conclusion

inepro’s decision to switch to energy-efficient LED lamps is an example of how companies can make positive changes in their pursuit of sustainability and cost savings. The energy savings and lighting improvements not only benefit the company itself, but also contribute to a healthier planet. This transition underlines the importance of continuous innovation and awareness.
