About SignatureLab
The Mission
SignatureLab gives consumers objective, data-driven flash intensity measurements. Product marketing is full of vague claims. We put products on the bench.
The Lab
Each test is recorded by calibrated photodiode sensors connected to an oscilloscope. Every product is measured on a standardized test platform under controlled conditions, and the resulting light pulses are captured.
Independence
SignatureLab accepts no manufacturer sponsorships or compensation to influence results.
