People cannot survive without light, which is a basic need. However, all lights consume energy, and energy is becoming increasingly scarce. A bulb light consumes the most energy because it is the most commonly used light. It is critical to understand how to make light bulbs use less energy. We were fortunate in that we developed a new bulb light that uses LED as a light source, which we call led bulb light. G4, G9, R7S, as one of the first companies specializing in lighting, can provide you with the ideal led bulb light. The stained glass cob series is ideal for high-transmittance applications that integrate into a design concept, as well as high-tech lighting applications like automotive and aviation. Lamp cups of the G4, G9, and R7S series are commonly used in projection lamps, hanging lamps, and auxiliary decorative lamps. It has a more appealing appearance as a result of the appearance of glass COB, as well as an improved luminous angle and efficiency. It's the glass cob series, which saves space and money by utilizing the entire lamp bead body. Low energy consumption and energy savings of up to 80%: Our bulb lumen efficiency is regularly 80lm/w based on a test report from the Everfine photoelectricity test machine, compared to a traditional incandescent bulb, which is four times brighter based on the same power. To replace those old lights, you can use 80% lower power COB LED bulbs. We can also increase the lumen efficiency to 100lm/w for high-end needs. Longer life expectancy: LED bulbs have a life expectancy of 15000 hours, which is twice that of CFLs and 15 times that of incandescent bulbs, according to factory testing data. Based on temperature testing, the temperature of the led is well controlled within 100°C, and the COB LED bulbs can be turned on and off 30,000 times. If you use one bulb for three hours per day, it will last 5000 days, or 13 years. High color rendering index (CRI 80) for vibrant colors: The color rendering index (CRI) describes how a light source affects the appearance of colors. Natural outdoor light has a CRI of 100 and is used as the baseline for all other light sources. Our products' CRI is always greater than 80, close to the value of the sun, reflecting colors truly and naturally. Designed with your eyes in mind: It's easy to see how harsh lighting can cause eye strain. Glare occurs when the light is too bright. When the light is too soft, flicker occurs. Our bulbs are designed with a soft light that is easy on the eyes and creates the ideal ambiance for you. When turned on, there is instant light: G4, G9, and R7S COB LED bulbs provide their full level of brightness in less than 0.5 seconds after turning on. Various color options: Light can have different color temperatures, which are measured in Kelvin units (K). A low Kelvin value produces a warm, cozier light, whereas a high Kelvin value produces a cool, more energizing light; 3000k, 4200k, and 6500k are more popular and should all be available. Environmentally friendly and safe: G4, G9, R7S COB LED bulbs contain no hazardous materials, making the product environmentally friendly, safe for any room, and easy to recycle. Overall, G4, G9, R7S COB LED bulbs are energy efficient, long-lasting, comfortable, and environmentally friendly, making them the best replacement option.
