The Viribright T8 18w LED Tube (4ft.) Ballast Bypass is an ideal 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. This tube can be used without a ballast (direct wire) which reduces overall energy consumption of the fixture. The total energy consumption of this tube is 18W while producing in excess of 2200 lumens in 4000K and 5000K 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.
- Glass Tube
- Single or Double Ended Wiring
- Compatible with T8 & T12 fixtures. Simply take out the Ballast for retrofitting.
- Use shunted or non-shunted tombstone for T8 tube install.
- T12 tubes don’t need tombstone change (1.5″).
General Information about T8 LED Tubes
T8 18w LED Tube 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 18W T8 tubes that can be used in the presence of moisture. As such, they should never make contact with liquids.
