The Speras BluDive BD40 Pro is a premium underwater torch engineered for demanding diving application—from search & rescue to deep recreational dives. It uses a Luminus SFT70 LED to generate up to 3000 lumens, projecting a focused 6.3° beam reaching 464 meters.
Controlled via a stainless-steel side switch (with memory function and battery indicator), the BD40 Pro offers an intuitive interface for divers. It includes reverse polarity protection, over-discharge protection, and an aerospace-grade aluminum body built to withstand depth pressure to 150 meters (IPX-8). Runtime in low mode can reach about 4.4 hours, while turbo mode gives around 2 hours.
Compact but powerful, it’s ideal for underwater photographers, cave diving, spearfishing, and technical diving tasks where a robust spotlight is needed.
