Why replace existing T12 tubes with triphosphor T8 lamps rather than the less expensive halophosphate T8 versions?
A Although both will provide approximately 10% energy saving, the triphosphor tube will give about 12% more light and greatly improved colour rendition. Combined with excellent lumen maintenance, the service life of the triphosphor tubes can be almost twice that of the halophosphate tubes, virtually halving annual lamp replacement and maintenance costs, which will more than offset the extra cost of the triphosphor tubes.
