How We Tested This Product

Our rigorous, independent testing process

Purchased
October 2025
Testing Period
30 days
Tested By
Ezra Maddox

Battery Life Testing We fully charged the Gritin light and tested runtime across all settings: low brightness (warm mode) for 88 hours continuous use, medium for 32 hours, and high for 11 hours. Compared to claims, it exceeded specs by 10% on low. We used a lux meter to maintain consistent output.

Build and Usability Clipped to hardcover books, paperbacks, Kindle Paperwhite, and iPad Mini; assessed grip strength (held 2kg load), gooseneck flexibility (full 360° without sagging after 100 bends), and button responsiveness over 50 cycles. Eye strain evaluated via 4-hour reading sessions under each color temp.

Brightness and Comfort Measured 180-220 lux at 6 inches (two-page coverage) with no hotspots or flicker (confirmed via high-speed camera). Side-by-side with competitors like Glocusent for evenness and dimming precision.
