The LED T8 tube range is a direct replacement for a standard T8 fluorescent tube. The LED tube is a direct retrofit for the fluorescent tube in a magnetic ballast or switch start liminaire without the need to bypass the ballast or remove the starter. In order for these tubes to work in a high frequency or electronic ballast luminaire a modification needs to be made. This involves bypassing the control gear in the fitting and you may require a electrician to carry out this work. These tubes are ideal for applications for where a reduced lumen output is sufficient and due to their extended life offer substantial savings against their fluorescent counterparts.
