1) Advantages of LED tubes over fluorescent tubes

The many advantages of LED tubes over fluorescents are covered quite extensively, so we won't go into depth, but the three primary advantages are:

Higher efficiency, energy savings (up to 30-50%)

Longer lifetimes (typically 50k hours)

No mercury

2) Fluorescent tubes sizes and LED tube light retrofitting

Because fluorescent fixtures are often mounted into ceilings and connected directly to mains electricity, they are relatively expensive and difficult to replace completely.

As a result, it oftentimes makes the most economical sense to simply use the same fluorescent fixture, but replace the fluorescent tube with an LED tube light.

Therefore, it is important to understand the types of fluorescent tubes that were developed, so that the correct LED tube light can be retrofitted in place.

Over the years, fluorescent tube manufacturers developed many varieties of sizes and types.

T8 4-ft: Four-foot T8 fluorescent lamps are the most commonly used type today. They are 48 inches in length and have a 1-inch lamp diameter.

T12 4-ft: Four-foot T12 fluorescent lamps are less efficient compared to T8 lamps. They are the same length as T8 lamps but have a larger 1.5-inch lamp diameter.

T5 4-ft: Four-foot T5 fluorescent lamps are typically the most efficient, and some of the newest types of lamps introduced in the 2000s in the USA. They are commonly designated T5HO (high output) and provide more brightness than their T8 counterparts. They are slightly shorter than four feet (45.8 inches). T5 lamps come in a variety of lengths such as 1-ft, 2-ft, and 3-ft versions and are commonly used in non-ceiling fixtures such as table lamps.

T8 and T12 tubes are also available in other lengths such as 8-ft tubes, but 4-ft lengths remain the most common types.

LED tube lights to replicate the mechanical dimensions to ensure that they can be true retrofit replacements, and adopt the same form factor names (e.g. 4-foot T8 LED tube light).

T8 and T12 fixtures are generally the same length and use the same pins, so mechanically they are usually cross-compatible.

T5 fixtures are NOT cross-compatible with T8 and T12 lamps due to their different pin sizes and actual length.

The features of LED panel lights

LED panel light is composed of backlight module, light, driving, frame structure and diffuser plate. Light irritates from both sides or edges of the light guide material and changes the light advancing direction after the processing of light interference pattern. Most of the interfered light will shine out directly from the diffuser plate and only a small amount of the light will be reflected on the reflective material fraction for a second secondary reflector. All these light shines out as far as possible to achieve the illumination purpose.

LED Panel Light is energy-saving: High energy efficiency and non-pollution, DC drive, ultra-low power consumption, saving more than 70% than traditional energy sources;

LED panel light is green: there is no ultraviolet ray or infrared ray in its spectrum, that is, no heat and no radiation. It is the typical green lighting that is safe to touch,;

LED panel light has long lifespan: presently the lifespan of LED has reached 100,000 hours or more. With the continuous development of LED technology and the popularity of its application, if the drive and the dissipation could basically achieve the ideal state, the lifespan of commercially available high-quality LED lamp basically could reach 10000-50000 hours, almost 10-50 times longer than normal halogen spotlights. ;

The flexible application of LED panel light: ultrathin and light, easy to install and space saving. It can be made into any graphic shape and any color, or even designing the color changing effects according to requirements;

The emitting mode of LED panel light: This light source is side-ting edge emission. The surface is bright and the light is even with no glare.
