The 58W Sylvania T8 S.A.D. Fluorescent Tube can assist in treating and preventing Seasonal Affective Disorder, which is a form of depression associated with lack of daylight exposure during winter months. This tube closely emulates daylight through the overall colour of its light and, importantly, its superb underlying ability to render colours naturally.

Ideal for installation in office or home areas without good natural light, the Sylvania T8 S.A.D. Tube emits 3700 lumens of cool white 6500K 'daylight' illumination. This linear lamp radiates across all or most wavelengths of the visible spectrum to deliver an incredible CRI 98 score. It also emits a minimal amount of UV. Very few other lamps on the market can mimic daylight in such a complete way.

Aside from alleviating S.A.D. symptoms and promoting mental and physical wellbeing, the Sylvania T8 S.A.D. Fluorescent Tube is a superb choice for colour-critical environments such as art studios, print shops, photo labs, graphic design houses, beauty and hair salons, or retail.

This dimmable T8 tube can be slotted directly into any existing T8 fluorescent light fitting, and boasts a long 20,000 hour lifespan. A 2-pin G13 cap is used for connection.


The dimensions of the 58W Sylvania T8 S.A.D. Fluorescent Tube are:
