4-Foot 22W T8 Tube Product Description
The Viribright 4-Foot 22W T8 (ft.) Ballast Bypass LED is high powered choice for installation in retrofit fixtures requiring 4ft. linear fluorescent tubes. These tubes will commonly be found in workshops, offices, grocery stores and convention halls but its brightness is on the higher side of its category. This tube must be used without a ballast (direct wire) which reduces overall energy consumption of the fixture. The total energy consumption of this tube is 22W while producing in excess of 2900 lumens in 5000K and 6000K color temperatures. These tubes are easy to install, but it is recommended to have a certified electrician handle the bypassing of the ballast and installation. This tube is also available in convenient packs of 10 or contractor packs of 25.

- Compatible with T8 & T12 fixtures. Simply take out the Ballast for retrofitting.
- Use shunted or non-shunted tombstone for T8 tube install.

General Information about T8 LED Tubes
22W T8 tubes are high powered and generally manufactured in three types although the ballast bypass version is the most common type sold in the US. These being the hybrid, the ballast bypass, and the plug-and-play. Unlike the others, the easiest to install is the plug-and-play variant. These can be easily plugged into compatible fixtures. However, it’s best to ensure that the ballast is compatible.
Compatibility details should be found in the Details tab of the products page. Direct wire lamps or the ballast bypass tube requires you to first remove the old ballast. For the most part, this eliminates future ballast maintenance and failure point issues.
However, the fixture may require some rewiring if it is either a double-ended or single-ended operation. Double-ended tubes are known for requiring power on either end while single-ended ones revolve around just one side needing power. When it comes to hybrids, these are simply a unique combination of the other two previously mentioned.
The LED tubes on this one begin as plug-and-play where the ballast eventually becomes unusable. When this occurs, the fixture becomes a bypass lamp. Hence, the ballast is removed and the lamp is rewired to suit the new ballast.
Tips For Choosing the Right Tube
When it comes to choosing the ideal tube, it is recommended that you first check the ratings, color temperature, and certifications associated with the tube. If you didn’t already know, the temperature is measured in Kelvins and is a representation of the light’s color. Those located between the 3000 to the 3500 Kelvin range are ideal for creating warm areas.
In essence, they create the perfect waiting or lobby area. Tubes between 4000 and 5000 Kelvins aid with increasing visibility and significantly reducing eye strain. These are suited for warehouses, classrooms, offices, and hospitals.
The certifications and ratings on these will give a better idea of where and how they can be efficiently and safely used. Those rated as dry location tubes should only be used in an indoor setting and should not be in contact with moisture or water. However, caution should still be taken for 22W T8 tubes that can be used in the presence of moisture. As such, they should never make contact with liquids.
