Please select the correct length and diameter bulb (T8 = 1'' tubes, T12 = 1.5'' tubes).

Designed for the highest Color Rendering Index (CRI) using Lumiram’s patented phosphor blends, providing a unique color unseen before. The 1XZ has a slightly higher amount of red in its spectrum, which allows this lamp to blend beautifully with Chromalux® incandescent lighting.

Recommended for general illumination of any kind, especially those requiring excellent color balance. Plants will love this light, too, thanks to the excellent balance of blue and red spectrum light present in this bulb!

Made in the USA!

Fluorescent tubes are final sale. Please double-check that you have selected the correct length and diameter bulb (T8 = skinnier 1'' diameter tubes, T12 = 1.5'' diameter tubes). If you're unsure, please contact customer service for assistance finding the correct sized tube for your application.
