How Many Watts Does a T8 Light Bulb Use?
If you are looking for a money-saving way to provide plenty of light in your home or office, you should consider T8 light bulbs to replace those old power-hungry light bulbs you are currently using. T8 light bulbs come in a wide assortment of lengths and wattages and can help cut your electric bill up to 40 percent versus using older T12 type bulbs.
Common Sizes and Wattages of T8 Light Bulbs
The most common length for T8 light bulbs is the standard 24-inch bulb you would find in many commercial businesses or offices. However, T8 bulbs are also frequently sold in 12, 15, 18, 36 and even 48-inch length versions. Generally speaking, if there is a T12 length bulb available, there is a T8 type replacement that can save you some money while providing nearly the same luminescent brightness level.
The most popular wattage for T8 light bulbs is the 32-watt type, which is intended to replace older 40-watt T12 bulbs. Nevertheless, there is a large assortment of T8 wattages available as well. For instance, T8 bulbs are often sold in 10, 14, 15, 17, 18, 25, 28 and 30-watt variations.
Typical Savings Versus Other Fluorescent Bulb Types
If you consider the amount of energy used versus the amount of light that is emitted by a light bulb, then T8 bulbs are by far more efficient than other types of bulbs. For example, a certain T12 light bulb that consumes 35 watts of power per hour creates only about 1400 lumens of light. Conversely, a T8 bulb can create the same level of light while only consuming 18 watts of energy per hour.
