Why should you care about the LUMEN rating of solar LED lights?

In the myriad of solar lighting products that vary in brand, design, power, and price range, how do you choose solar lights that meet quality standards, with LED chips that have good brightness and durable lifespan? Let’s explore this with DAT Solar in the following article!

What should you pay attention to when selecting a good LED bulb?

Compared to common types of bulbs in the market such as Halogen, CFL, HID, LED bulbs remain the optimal choice due to their excellent lighting capabilities, consistent brightness, energy efficiency, and above-average lifespan. Among these, the LED chip is the most crucial component, determining the light intensity, causing minimal harm to the eyes, and offering energy savings of up to 70% compared to conventional bulbs, with 5-10 times the brightness of Halogen bulbs. This is why LED lights are favored by many customers and applied to projects for high performance.

Therefore, to choose a high-quality solar light, attention must be given to the LED chip. Among the various LED chip options ranging from budget to premium, the Philips brand from the Netherlands is highly regarded by customers worldwide for its quality and reliability, backed by 131 years of experience in the electronics and home appliances industry. Philips continually researches and applies new technologies to LED chips for optimal performance and durability.

Understanding the customer’s desire for “Standard quality” solar lights, Sokoyo uses Philips’ LUMILEDS 3030/5050 LED chips, which boast a high luminous efficacy of 170lm/W, a lifespan of up to 50.000 hours, and durability equivalent to 12 years. As a result, Sokoyo’s lights operate more efficiently, are more durable, require less maintenance, and customers can use them with confidence for an extended period.

Why should you care about the Lumen (lm) rating of LED lights?

What is Lumen? Lumen is a unit of measurement for light, the derived SI unit of luminous flux, measuring the total amount of light emitted by a lamp.

In the past, when choosing lights, we only paid attention to Watts (W), assuming that higher wattage meant more light. However, in reality, to measure the brightness of a bulb, it’s crucial to consider the Lumen quantity (luminous flux) of the bulb. Below is a comparison table between conventional solar lights and Sokoyo solar lights in terms of Lumen rating.

As seen in the table, Sokoyo’s 30W solar light, while six times smaller in wattage compared to another 200W light, utilizes the LUMILEDS 3030 LED chip with a luminous efficacy of 170lm/W, resulting in a total luminous flux of up to 5023 lumens. In contrast, the 200W light only provides 4398 lumens of luminous flux.

To achieve higher luminous efficacy, besides using high-efficiency LED chips, the design of the light housing and LED modules also contributes to the overall lighting performance. The LED module design should have a batwing lens for each LED chip, and a well-designed heat dissipation system for the light housing ensures that the light operates cooler, more stable, and more durable throughout its operational life.
