A19 vs E26 – Brightness and efficiency
Comparison of the brightness of A19 and E26 bulbs
A19 refers to the bulb shape, which is a standard shape used in many household light bulbs. It has a diameter of 19/8 inches or approximately 2.4 inches. A19 bulbs are available in a variety of wattages and brightness levels, ranging from around 40 watts (for low levels of light) to 100 watts (for high levels of light).
E26, on the other hand, refers to the type of base used on the bulb. E26 is a standard screw-in base that is used in many types of light bulbs, including A19 bulbs. Other types of bulbs may also use the E26 base, such as BR30 (a bulb shape) or PAR38 (a flood light).
In other words, A19 and E26 bulbs can both come in a range of brightness levels, but they are not comparable in terms of brightness. It’s like comparing the size of a car tire (a measurement of diameter) to the type of fuel it uses (gasoline, diesel, electric, etc.).
Comparison of the efficiency of A19 and E26 bulbs
A19 and E26 are not directly comparable units of measurement. A19 refers to the bulb shape, while E26 refers to the type of base used in the bulb. Efficiency of a bulb is typically measured in terms of its efficacy, which is the amount of light output (lumens) per watt of electricity consumed.
So, it’s more appropriate to compare the efficacy of different types of bulbs that use the same base, such as A19 and BR30, both of which use an E26 base.
In general, the efficacy of a bulb is influenced by several factors, such as the type of technology used (e.g. incandescent, LED, CFL), the color temperature of the light, and the quality of the components used in the bulb.
When comparing A19 and BR30 bulbs with similar specifications (e.g. wattage, color temperature), the efficacy can vary widely depending on the type of technology used. For example, an LED A19 bulb may have an efficacy of around 100 lumens per watt, while an incandescent A19 bulb may only have an efficacy of around 10 lumens per watt.
LED bulbs tend to be more efficient than other types of bulbs, including incandescent and CFL. So, if you are looking for a more efficient bulb, it is recommended to choose an LED bulb with an E26 base.
A19 vs E26 – Cost
Comparison of the cost of A19 and E26 bulbs
A19 and E26 refer to two different types of light bulb base sizes. A19 bulbs have a medium E26 base, which means that they are interchangeable with E26 bulbs.
The cost of A19 and E26 bulbs can vary depending on the brand, wattage, and other factors. However, since A19 bulbs have an E26 base, their cost is generally similar to E26 bulbs.
On average, the cost of a basic A19 or E26 LED light bulb ranges from $2 to $10, while incandescent bulbs are typically cheaper, ranging from $0.50 to $2 per bulb. However, LED bulbs tend to be more energy-efficient and can last up to 25 times longer than incandescent bulbs, which can make them a better long-term investment despite their higher upfront cost.
The cost of bulbs can vary significantly depending on where you purchase them, so it’s always a good idea to compare prices at different retailers before making a purchase. Additionally, the cost of operating a bulb over its lifetime should be considered when evaluating the overall cost of different bulb options.
