The T5 luminary is an offshoot of the fluorescent lamp, which is very efficient, sleek, and brilliant. It is perfect for lighting up low-profile fixtures such as display cases and shelves because it is thin and bright. Thus, even if a retail store has limited space, it can still put up great lighting fixtures and effects with the use of the T5 lamp. This lamp is also ideal for low-level ceilings where only smaller and sleeker fixtures can fit. So, if you are into retail business, consider installing T5 lamps in your store. It is an energy-efficient, bright, and space-saving option for you.
