TCP has a new SelecT8 line of LED T8 lamps that allow for color-select on the tube itself! Choose from 3500K, 4000K or 5000K on the tube and remove the guessing game of which color temp you want (or get the new Type B version that is 3000K-65000K!) Available in Type A (uses ballast) or Type B (ballast bypass) and in 4'. New for 2023 is a Type AB SelecT8 lamp that can be used on a ballast or once the ballast dies it can bypass the ballast, all while having the color-select technology for added versatility.
