Stealth Scuba Diving Headlamp with Blue and Green LEDs. 60 torch lumen blue and green LED diving headlamp with a salt water resistant (titanium contact) slide switch, which prevents the light from accidentally being turned on or off due to water pressure at depth. Blue and green light enables more covert diving where the diver can get closer to marine life. This color combination doesn't provide true coloration (like white light) but is better at cutting through mild to moderate silt and sediment. Designed for SCUBA diving - waterproof to 150 ft (46 m).
