Bludive: The Premium Diving Torch Brand by SPERAS
Bludive is the dedicated professional underwater illumination sub-brand of SPERAS. We combine SPERAS's industry-leading flashlight manufacturing technology with hardcore marine engineering to provide divers with the safest, most reliable underwater lighting solutions.
A true Professional Dive Torch is not just a 'waterproof flashlight.' It is vital life-saving equipment. It must withstand crushing underwater pressure, resist highly corrosive salt water, and feature specialized optical designs to penetrate murky, particle-filled water. Whether you are engaging in recreational reef diving, deep-sea exploration, or spearfishing, Bludive illuminates the abyss with absolute certainty.
Bludive vs. Industry Standards
Why professional scuba and freedivers choose Bludive over standard underwater lights:
| Feature | Standard Dive Lights | Bludive by SPERAS |
|---|---|---|
| Waterproof Depth | Typically 50m - 100m (IPX8 limits). | Extreme 150m (492ft) safe diving depth with Double O-ring seals. |
| Switch Mechanism | Twist-head or physical push buttons (prone to leaking/sand jams). | Titanium alloy magnetic switches (zero hull penetration, anti-corrosion). |
| Beam Penetration | Wide but short-range beam, scattered by marine snow. | Optimized deep reflectors for massive throw and murky water penetration. |

Why do Bludive torches use magnetic switches?
Traditional push-button switches require a physical hole in the flashlight body, which is a common failure point for leaks under high water pressure. Bludive utilizes Titanium alloy magnetic switches. This allows the flashlight body to remain completely sealed as a solid piece of aerospace aluminum, ensuring 100% waterproof reliability down to 150 meters while preventing salt and sand jams.
How deep can Bludive flashlights go underwater?
While standard IPX8 ratings only guarantee water resistance up to roughly 2 meters (or slightly more), Bludive professional diving torches (like the BD42 and BD40 PRO) are engineered with double O-ring seals and 4mm thickened tempered glass. They are rigorously tested to operate safely at depths of up to 150 meters (492 feet).
How should I maintain my diving torch after a dive in the ocean?
Saltwater is highly corrosive. After every ocean dive, you must rinse your Bludive torch thoroughly with fresh water while pressing/moving the switch to clear out any trapped salt crystals or sand. Dry it completely with a towel before opening the battery compartment. Periodically inspect and lubricate the O-rings with silicone grease to maintain the 150m waterproof seal.
