A clever demonstration by Nurse Beccy has sparked viral curiosity on TikTok, where her video revealing that surgical lamps don’t cast shadows has drawn over 248,100 views. The clip shows Beccy placing her hand directly under the lamp, only for viewers to realise there’s no shadow at all.

The reason? Surgical lamps are designed with multiple overlapping light sources that eliminate shadows, ensuring consistent illumination during procedures regardless of hand placement. It’s a subtle but vital feature that helps surgeons maintain visibility and precision.

As a fun fact, that surgical lamps are made so they don’t cast shadows , impressive in the sense that you can always get the perfect light while operating no matter where you place your hands.
