Energy Savings Up to 41%! NATIONSTAR High-Efficiency LED Lighting Empowers Three Major Scenarios, Witnessing Hardcore Energy-Saving Strength

Energy-Saving Star Products

As night falls, LED street lamps on urban roads light up one after another like stars. They not only illuminate roads warmly and brightly, but also inject new energy-saving impetus into the green development of cities.

The low power consumption advantage of LED products is widely known, but do you know their specific energy-saving efficiency? Today, taking NATIONSTAR's high-performance, high-luminous-efficiency LED lighting series as examples, we analyze their energy-saving performance in common lighting scenarios to reveal the energy-saving strength of NATIONSTAR's LED lighting solutions!

Road Lighting | 41% Annual Energy Saving Rate per Lamp

At present, most urban street lamps in China are high-pressure sodium lamps. Traditional high-pressure sodium lamps feature high energy consumption, low luminous efficiency and considerable power consumption.

Independently developed by NATIONSTAR, the outdoor high-luminous-efficiency 5050 LED device boasts a luminous efficiency of up to 240lm/W and high reliability, enabling better adaptation to harsh outdoor environments. It provides a superior technical solution for outdoor applications such as municipal street lamps.

Taking the renovation of arterial road street lamps as an example, the original 250W high-pressure sodium lamps are replaced with NATIONSTAR outdoor high-efficiency 5050 LED devices (at the same brightness, a lamp uses about 147 LED devices with a total power of approximately 147W):

Power Saving Formula

Annual power consumption per lamp = Power (kW) × Time (hours/day) × Days

Annual power consumption of original lamp = 250W × 10 hours/day × 365 days ≈ 912.5 kWhAnnual power consumption of NATIONSTAR outdoor high-efficiency 5050 LED devices = 147W × 10 hours/day × 365 days ≈ 536.5 kWhAnnual power saving per lamp = 912.5 − 536.5 = 376 kWhAnnual energy saving rate per lamp: about 41%

Shopping Mall Lighting | 36% Annual Energy Saving Rate per Lamp

As a high-energy-consumption venue, lighting usually accounts for no less than 30% of a shopping mall’s total electricity use.

To meet the energy-saving demands of commercial lighting, NATIONSTAR’s independently developed commercial high-efficiency 2835 LED devices achieve a luminous efficiency of up to 230lm/W, a service life of over 50,000 hours, and support multi-channel precise dimming, enabling “lighting on demand” to help improve the quality and efficiency of shopping mall lighting.

Taking a general shopping mall as an example, if 16W traditional LED lamps are replaced with NATIONSTAR 0.2W commercial high-efficiency 2835 LED devices (under the same brightness, about 50 LED devices are used per lamp with a total power of approximately 10W):

Power Saving FormulaAnnual power consumption per lamp = Power (kW) × Time (hours/day) × Days

Annual power consumption of original lamp = 16W × 12 hours/day × 365 days ≈ 70.08 kWhAnnual power consumption of NATIONSTAR commercial high-efficiency 2835 LED devices = 10W × 12 hours/day × 365 days ≈ 43.8 kWhAnnual power saving per lamp = 70.08 − 43.8 = 26.28 kWhAnnual energy saving rate per lamp: about 36%

Office Lighting | 26% Annual Energy Saving Rate per Lamp

In commercial office buildings, lighting power consumption accounts for a significant proportion of overall energy use.

To effectively reduce office lighting energy consumption and achieve energy conservation and emission reduction targets, NATIONSTAR’s independently developed smart lighting 3030 dual-color LED devices feature a color temperature range of 2700K–6500K and support intelligent dimming, providing customers with an intelligent office lighting LED solution that combines precise light control with energy saving.

Taking an office area in a commercial building as an example, if the original 30W traditional fluorescent lamps are replaced with NATIONSTAR 1W smart lighting 3030 dual-color LED devices (under the same brightness, about 44 LED devices are used per lamp, with a total power of approximately 22W for single-color lighting):

Power Saving FormulaAnnual power consumption per lamp = Power (kW) × Time (hours/day) × Days

Annual power consumption of original lamp = 30W × 10 hours/day × 250 days (estimated working days per year) ≈ 75 kWhAnnual power consumption of NATIONSTAR smart lighting 3030 dual-color LED devices = 22W × 10 hours/day × 250 days ≈ 55 kWhAnnual power saving per lamp = 75 − 55 = 20 kWhAnnual energy saving rate per lamp: about 26%

The above scenarios are based on single-lamp renovation for reference. If full-scale renovation is carried out, the energy-saving effect will be even more significant.

Energy-saving technological upgrading never stops, and cost reduction and efficiency improvement are endless. With the innovative development of LED technology, the energy-saving potential of LED lighting will continue to be unlocked.

Moving forward, NATIONSTAR will give full play to its technological advantages, accelerate the improvement of its high-efficiency LED lighting product portfolio, and actively expand application boundaries. Empowering multi-scenario cost reduction and efficiency enhancement with green light sources, the company will inject more stellar vitality into green and low-carbon development
