What brand is Sokoyo? Where is it from?

Jiangsu Sokoyo Solar Light Company is based in Yangzhou City, near Shanghai, established in 2008, and ranks among the top 2 solar light product manufacturers in China. Sokoyo is a professional manufacturer of solar street lights with a factory area of over 80.000m², autonomously producing solar panels, batteries, and lights to ensure quality control. The company can meet an annual capacity of over 250.000 sets for the market. With a highly skilled R&D engineering team, Sokoyo consistently innovates, enhancing light quality to meet the practical needs of customers.

Why is Sokoyo’s 40W solar street light brighter than conventional 40W solar street lights?

1. Is more watts equal to more brightness?

Selecting LED solar lights is entirely different from choosing incandescent lights. Applying incandescent light selection knowledge to purchase LED solar lights is not appropriate.

DAT suggests the following: Don’t focus on Watts (W), focus on Lumens (LM). Many people still habitually look at the light’s power to choose, thinking that higher power means greater brightness. While this is relatively true when considering LED lights, looking at the W only tells us about power consumption rather than brightness. To accurately know the brightness, look at the LM rating.

2. What are Lumens?

Lumens are a derived SI unit of luminous flux, measuring the total amount of light emitted by a light source. The symbol for Lumens is LM. If Lumens are higher, the light is brighter, and if Lumens are lower, the brightness is weaker.

To replace a 100W incandescent bulb, you need a bulb that provides 1600 Lumens. If you want dimmer light to save electricity, choose a bulb with lower Lumens; similarly, if you want brighter light, choose a bulb with higher Lumens.

3. Brightness capability of different lights

Incandescent lights have an efficiency of about 10-20 LM/Watt, Fluorescent lights have an efficiency of about 40-50 LM/Watt and LED lights have the highest efficiency, ranging from 80-100 LM/Watt. Currently, there are premium lights that can reach up to 170LM/Watt, such as the LUMILED chip equipped in Sokoyo lights.

4. Comparing the brightness of Sokoyo’s 40W solar street light to conventional 40W solar lights

	Power	LED Chip Efficiency	Theoretical luminous flux	Actual luminous flux (~90% of theoretical luminous flux)
Solar street light 40W conventional	40W	100LM	= 40W x 100LM = 4,000LM/W	3,600LM/W
Solar street light 40W Sokoyo	40W	170LM	= 40W x 170LM = 6,800LM/W	6,120LM/W

Note: Actual brightness is reduced compared to theoretical due to factors such as LED chip arrangement losses and the light obstruction caused by the fixture’s corner.

5. Be cautious of the virtual power of solar lights

Have you ever wondered why solar lights, with the same power, appear much brighter than conventional lights?

Have you ever wondered why solar lights, with the same power, appear much brighter than conventional lights? Currently, many untrustworthy suppliers take advantage of consumers’ psychology by stating the maximum power that the source can convert in a very short time on the product. Presenting virtual power in this way aims to attract the attention of customers who do not fully understand the mechanism of solar lights. Therefore, if you see solar lights advertised with a large power, you should consider carefully before buying, as it may be virtual power that the manufacturer wants to showcase. The actual power of the 40W Sokoyo solar street light must have a much larger size than a conventional light with virtual power.

To better understand and grasp the lighting capabilities of solar lights, customers can visit DAT directly at the main headquarters in Ho Chi Minh City and branches in Can Tho, Hanoi for direct comparisons and visual assessments.

Applications of the Sokoyo 40W solar street light

1. Illumination of urban roads and real estate

The solar street light system is beneficial for lighting streets in urban areas and real estate with its wide illumination, making it easy for pedestrians to see signs, paths, sidewalks, and parking lots.

The solar light system operates independently, not relying on the power grid. Therefore, for urban road areas and real estate districts, solar street lights are an excellent, cost-effective, and low-maintenance choice.

2. Illumination of factory internal roads

The Solar LED lighting system features a special storage system that allows continuous lighting for up to 3 days before needing a recharge. In industrial centers, factories, and commercial centers where there is a large electrical load for lighting, solar lights are an excellent solution, meeting criteria for illumination capacity as well as cost savings on electricity and maintenance.

3. Illumination of urban traffic roads

Movement and transportation are crucial aspects of life, making ensuring safety through lighting essential. Therefore, saving electricity consumption each month is imperative. As a result, solar lighting technology is increasingly being recognized and applied, particularly in urban traffic scenarios.

Applying solar lights not only helps save electricity but also minimizes environmental pollution. Currently, solar lights are being utilized in various vehicles, including bicycles, boats, helicopters, cars, motorcycles, trains, and airplanes.

Moreover, these lights can operate in conditions with many clouds and provide reliable light at any time.

4. Illumination of rural traffic roads

In some areas, especially rural regions with limited power grid systems that do not meet lighting needs in traffic areas, inconvenience in vehicle movement occurs. Installing solar lights helps save costs for installation, power grid extension, and maintenance. Therefore, the application of solar lights in rural areas is gaining significant attention.
