9 best circle light bulbs

Circle light bulbs, also known as circular fluorescent bulbs or tube lamps, are a type of fluorescent lighting commonly used in various settings, including homes, offices, and commercial spaces. These bulbs are designed in a circular shape, which allows for even illumination over a wide area. Here are some key characteristics and information about circle light bulbs:

  1. Shape and Size: Circle light bulbs typically have a tubular, circular shape, with a diameter ranging from 6 inches (15 cm) to 16 inches (40 cm) or more. The most common sizes are 8 inches (20 cm) and 12 inches (30 cm).

  2. Light Output: Circle light bulbs produce a soft, diffused light that is well-suited for general ambient lighting. The light they emit is relatively even and less harsh compared to some other types of lighting.

  3. Efficiency: Fluorescent circle bulbs are known for their energy efficiency. They use less energy and produce less heat compared to traditional incandescent bulbs, making them cost-effective and environmentally friendly.

  4. Color Temperature: These bulbs are available in different color temperatures, ranging from warm white (around 2700K) to cool white (around 5000K), allowing you to choose the desired lighting ambiance.

  5. Ballast: Most circular fluorescent bulbs require a ballast to operate.The ballast regulates the electrical current flowing through the bulb, ensuring stable and flicker-free lighting. Some newer models may use electronic ballasts for improved efficiency and performance.

  6. Applications: Circle light bulbs are commonly used in various applications, such as ceiling fixtures, pendant lights, table lamps, and wall sconces. They are often used in settings where a wide, uniform light distribution is desired.

  7. Longevity: Fluorescent circle bulbs tend to have a longer lifespan compared to incandescent bulbs. They can last anywhere from 10,000 to 20,000 hours or more, depending on the quality and usage.

  8. Disposal: It's important to note that fluorescent bulbs contain small amounts of mercury, which is a hazardous material. Therefore, proper disposal is essential to prevent environmental contamination. Many regions have specific recycling programs for fluorescent bulbs.

  9. Replacement: If a circular fluorescent bulb fails, it can usually be replaced with a compatible bulb of the same size and type. However, it's essential to match the wattage, color temperature, and type of ballast to ensure compatibility.

  10. LED Alternatives: With the advancement of LED technology, circular LED bulbs have become available as energy-efficient alternatives to fluorescent circle bulbs. They offer similar benefits in terms of energy savings but without the need for a ballast.

In summary, circle light bulbs, or circular fluorescent bulbs, are energy-efficient lighting options commonly used for general illumination in various settings. They come in different sizes and color temperatures, making them versatile for different applications. However, proper disposal of these bulbs is crucial due to the presence of mercury.

User questions & answers

Question: Can you replace 60w for 40w
Answer: I am sure that because they work with an ordinary dimmer they will work with any dimmer. If a light bulb is not dimmable then it will be damaged by any kind of dimmer. So I am confident these bulbs will work with a smart dimmer. I assume the smart dimmer is some kind of programmable device or has a wifi connection. The guts that operate the bulb will be the same as an ordinary dimmer. I have 5 years of education in Electrical Engineering and Computer Engineering.
Question: How long are the bulbs
Answer: How about view the b10 soft white bulbs with frosted glass, please search the ASIN number B07WNZPN84 on Amazon.com
Question: Do they get hot
Answer: I'm not personally using mine on a dimmer, so I can't speak for those, but I do live off-grid and have a modified sine wave inverter, which doesn't play nice with many electronic things and can make many CFLs and LEDs hum or buzz. I haven't personally observed a buzz, although I will say they definitely flicker with the slightest voltage fluctuation.
Question: are these a candleabra base
Answer: No writing on the glass. On the metal contact, the electrical/size specs "2W D9" are etched

User questions & answers

Question: What ballast should I order for these lights
Answer: This set contains 62 sockets. You can view the list of whats included via our web site.
Question: My rv has bulbs with the t5, 8w, cw, 4000k will those here marked 4100k work instead
Answer: Yes, our manufacturing warranty would cover the tools.
Question: What Voltage are these
Answer: Yes, the sockets may be attached to an impact.
Question: Can these bulbs be used with dc current fixtures in my rv
Answer: The 192 piece set is the better set if you want more sockets and extensions. The 247 piece isn't really 247 if you take away all the little screwdriver bits. The only advantage to the 247 piece set is the wrenches, which the 192 piece set doesn't have. But the 192 piece set has more sockets and more extensions. If you want an all-around kit, the 247 piece is nice because you have the screwdriver set and the wrenches. But if you want a better kit of just sockets and ratchets the 192 is the better kit.
