Our Ultra Bright class of short tape measures are easy to read in low light environments, and stay visually cleaner than black and white blades. Great for in-shadow measurements, for instance, those in cabinets and in corners. Also helpful in the meager light of dawn and of dusk. We've increased the number size to make them easier to read in any condition. We also have added a vertical reading feet and inches scale on the reverse side for vertical measurements. We placed these high-contrast, large-numbered, blades in a solid-ABS housing that is further protected by rubber casing.
