Case Study of Workshop Tube-in-Tube Energy Saving Lamps
Case Study of Guangzhiguang Tube-in-Tube Energy Saving Lamps
Section 1: Analysis of Investment Returns on Guangzhiguang Energy Saving Lamps
Now let us analyze our investment returns with specific examples, using intuitive data to experience the charm of energy saving lamps . The following example uses Guangzhiguang tube-in-tube high-efficiency energy saving lamps G120, assuming a sales price of 69.9 yuan per unit (subject to actual prices; the example is for reference only).

1.1. From the above data, we can see that the benefits of energy-saving lamps are directly proportional to the number of lamps, lamp power, usage duration, electricity price, and the energy saving rate of the lamps. We cannot deliberately reduce expenses regarding the number of lamps, lamp power, and usage duration. However, by obtaining energy-saving lamps with the optimal cost-performance ratio, we can achieve significant cost savings. At the same time, we also observe that the higher the local electricity price, the greater the benefit of using energy-saving lamps.
1.2 The service life of ordinary fluorescent lamps differs significantly from that of various energy-saving lamps, which further demonstrates the charm of lower maintenance costs of energy-saving lamps. The T5 energy-saving lamps and tube-in-tube high-efficiency energy-saving lamps have a lifespan of approximately 30,000 hours. In contrast, the general lifespan of ordinary fluorescent lamps is 10,000 hours.
1.3 Currently, all energy-saving lamps produced by our company are starter-free and free of independent ballasts. If customers choose newly installed energy-saving lamps, they can avoid another considerable expense.
1.4 As ordinary fluorescent lamps age, their luminance gradually decreases, and their actual power consumption gradually increases (44W). In contrast, the tube-in-tube energy-saving lamps produced by our company have relatively lower current and less heat generation, so the aging speed of the lamp tube is relatively slower. Although the luminance decreases somewhat, the power consumption remains stable and unchanged.
1.5 Customers can create a simple algorithm based on their actual usage conditions to optimize their investment plan.
Section 2 Horizontal Comparison: Current Conventional Energy Saving Lamp Solutions
Now we compare conventional energy saving lamp products on the market with our Guangzhiguang tube-in-tube energy saving lamps.
2.1 The following example uses a conventional T5 energy saving lamp (28W, without cover), assuming a selling price of 30 yuan/unit (subject to actual price; for reference only).

2.2 The following example uses a conventional LED T8 fluorescent lamp (15W, without film), assuming a selling price of 200 yuan/unit (subject to actual price; for reference only).

2.3 The following example uses an LED T8 fluorescent lamp (18W, with film), assuming a selling price of 260 yuan/unit (subject to actual price; for reference only).

The following examples use LED T8 fluorescent lamps (20W, with film), assuming a selling price of 320 yuan/unit (subject to actual prices; for reference only).

Considering the glare from LED point light sources, a film is generally added inside the lamp tube during actual use to reduce irritation to the human eye. Without the film, the light transmittance is approximately 91%, while with the film, it drops to 79%, requiring the LED tube power to be increased to 18 watts to meet requirements. In reality, due to inherent defects in LED light sources, lumen depreciation for most LED products approaches 5% at 3,000 hours and nearly 30% at 30,000 hours. This means that while the brightness is currently equivalent to a 40-watt fluorescent lamp, after 3 years (30,000 hours), it will be less than 30 watts. Therefore, it is recommended that customers use 20W LED fluorescent lamps with film.
Section 3 Overview of Energy-Saving Lamp-in-Lamp Solutions
Assuming 1,000 lamp tubes replacing current 40-watt ordinary fluorescent lamps, with an electricity price of 1 yuan/kWh, the energy saving effects are shown in the table below for the following scenarios.

3.1 The above scheme does not consider the lifespan and maintenance costs of ordinary fluorescent lamps. Generally, the service life of ordinary fluorescent lamps is less than 10,000 hours. If considering
The cost for lamp replacement and maintenance is no less than 6 yuan per year per tube. In addition, our company's dedicated luminaires for the new installation type of Tube-in-Tube are very affordable, costing only 1/8 to 1/10 of ordinary luminaires.
3.2 The investment for the Tube-in-Tube energy saving lamp solution is: 80,000 yuan. Our company promises an 18-month warranty. The actual service life can reach 30,000 hours, with lumen depreciation within 5% after 20,000 hours;
3.3 The investment for the T5 energy saving lamp solution is: 30,000 yuan. The market standard warranty is generally 12 months. The actual service life can reach 20,000 hours, with lumen depreciation within 5%;
In summary, Guangzhiguang Tube-in-Tube energy saving lamps involve relatively small investment and offer very significant benefits, making them a key choice for decision-makers in various enterprises and institutions.
