What is the difference between G5 and G13 base ?

When it comes to light bulbs, the bases play an important role in how they function. Two prevalent bases are G5 and G13, which are similar in some ways but have some key differences.

The G5 base is a type of bi-pin base that is commonly used for fluorescent bulbs. It has two pins that are exactly 5mm apart, and the pins are inserted into matching sockets in the lamp holder. The pins are designed to fit securely into the sockets, ensuring a stable connection.

On the other hand, the G13 base is also a bi-pin base but it is larger than the G5 base. It measures 13mm between the pins, and is mostly used for T8 and T12 and LED tubes. Compared to the G5 base, the G13 base is more durable and less prone to failure.

Overall, the main difference between G5 and G13 bases is their size, which makes them suitable for different types of light bulbs. While both are important in enabling proper functioning of the bulbs, it's essential to choose the right base for your specific fixture.

In conclusion, being familiar with these two bases can help you better understand the lighting choices available to you. Whether you are replacing light bulbs, upgrading fixtures, or choosing new lighting options, knowing the difference between G5 and G13 bases can help ensure that you choose the right bulb for your needs.

Among the most popular kinds of LED tube lights are:

T8 LED tube with a diameter of one inch
T12 LED tube with a diameter of 1.5 inches
T5 LED tube with a diameter of 5/8 inch
Following the letter "T" is a number that represents the tube's diameter in eighths of an inch. As a result, the diameter of a T8 light is precisely 1 inch, or 8/8 of an inch.

These LED tube lights come in a range of lengths, from one foot (30 cm) to eight feet (240 cm).

LED tube lights have numerous advantages over fluorescent lamps.

Up to 50% energy savings compared to fluorescent lamps
Longer lifetimes - up to 50,000 hours of continuous operation
With proper design, higher color quality and lower flicker
No toxic chemicals such as mercury that can be released with broken fluorescent lamps

Lamp length: The length of the 18w T8 Led Tube Lights should precisely match the spacing between the fluorescent fixture's lampholders. You may physically measure the fluorescent fixture to confirm if you're not sure. For instance, the most popular T8 4-foot fixtures should have precisely 48 inches between the lampholders.

Lamp pins: The next step is to check for compatibility between the metal contact pins on the lamp's two ends. To verify this, the simplest method is to take out an existing light, look at the pins on the end, and measure the distance between them to find the pin specification. The G13 bipin (0.5 inch/13 mm apart) is the most popular kind for T8 and T12 lights, whereas the G5 bipin (0.2 inch/5 mm apart) is the most popular type for T5 lamps.

The G13 bipin is commonly used by both T8 and T12 lights. For this reason, a T8 LED tube light may be physically installed in a T12 fluorescent light fixture, and vice versa (provided they are the same length).

Neutral white and cool white are only two of the many white light colours that LED tube lights come in. The most accurate approach to characterise the colour of a light is to use its colour temperature, which is expressed in degrees Kelvin.

The majority of LED tube lights have a greater colour temperature (whiter/bluer) than domestic lighting products since they are intended for use in commercial, retail, and industrial applications. The majority of LED tube lights are in the 4000K to 6500K range, but most home bulbs are in the 2700K to 3000K range (i.e., warm white).

The "warmest" colour choice for LED tube lights is usually 4000K. A softer light colour that is frequently utilised in commercial and retail environments is 4000K light. It looks most like early or late afternoon sunshine and has a faint yellow-orange tint.

The light colour that most closely resembles midday is 5000K. It is utilised in color-critical applications in graphic arts, printing, and other visually demanding industrial processes since it is thought to be the most "neutral" white colour (also check for D50 ISO certified items). Strong, "bright" illumination is produced by 5000 K, which is often not appropriate for residential or house installations, particularly in the evening.

Last but not least, 6500K is a pale hue that most closely resembles a blue sky looking north. The ISO standard for digital arts and other screen-based work is likewise met by its D65 equivalent. Art studios and digital art studios (such as those that do post-production photography) are a good fit for 6500 K. Similar to 5000 K, we typically only suggest 6500K for specialised applications that need for a certain colour of daylight-calibrated light. A comparison between 5000K and 6500K may be seen here.

You should also take into account an LED tube light's colour rendering index (CRI) rating in addition to its colour temperature.

The degree to which the colour of light seems "warm" or "cool" is known as colour temperature. Conversely, colour rendering quantifies how accurately colours look under the light source. Colours may seem distorted, faded out, or indistinguishable in low CRI LED tube light. Items might seem as they would in natural daylight thanks to the light provided by high CRI LED products. Additionally, you should check the R9 value of an LED tube light, which offers more details on how red is represented.

For areas like parking garages and storage facilities, LED tube lights with a CRI value of 80 or below are often appropriate. 90 CRI or above is advised in areas like retail and industrial settings where colour appearance might begin to matter. 95 CRI or greater is typically required for the most color-critical installations, such as colour inspection stations or studios.

Q: How much energy will I save by converting to LED tubes?

A: You can save between 20% to 44% on energy costs. But it would vary depending on the LED type and installation.

Q: How long do LED tubes last compared to fluorescent tubes?

A: On average, LED tubes have a lifespan of around 50,000 hours. It can operate for over 17 years if used 8 hours daily. On the contrary, fluorescent tubes typically last between 10,000 and 20,000 hours. Compared to the LEDs, it is roughly 3 to 7 years under similar usage.

Q: What are the environmental benefits of switching to LED tubes?

A: LEDs use up to 80% less energy than fluorescent tubes. It helps reduce greenhouse gas emissions and even lowers the demand for power plants. All in all, you can help reduce the footprint and save nature.

Q: What is the difference between T8, T5, and T12 LED tubes?

A: T5, T8 are the smallest and most efficient, while T12 is the largest in size but least efficient. T5 requires electronic ballasts, while T8 and T12 work with both electronic and magnetic ballasts.

Q: Which Method is Best for Converting Fluorescent Tubes to LEDs?

A: You can choose any of the methods from plug-and-play or Type-A to ballast-bypass or Type-B. Most go for the Type-A tubes for easy installation using existing ballasts. Even Type-B tubes provide higher efficiency, but you need to remove and rewire them with the ballast.
