The Light Emitting Diode (LED) Assembly Battle Lantern Upgrade Kit provides enhanced benefits by:


Reducing the energy draw on the battery thereby increasing period of time with undiminishing, reliable light;


Preventing any chance that a broken incandescent light filament resulting from an onboard explosion or any impact will render the battle lanterns useless during an emergency;


Providing a clear, bright light that will permit medical personnel to work efficiently in the event of battle casualties.


Light Emitting Diode (LED) Assembly

Battle Lantern Upgrade Kit


The Office of Naval Research, Technology Solutions Program, initiated the development of the LED Battle Lantern in response to the attack on the USS Cole in October 2000 that resulted in the loss of 17 sailors’ lives.


The #1 finding of the investigation into the deaths and injuries aboard the USS Cole was that survivability during and following the attack was compromised due to lack of light;


There were NO rechargeable Battle Lanterns;


The critique showed that the standard Navy NON-rechargeable Battle Lanterns were NOT reliable due to the diminished capacity of disposable batteries, and;


The lamp filaments either broke or malfunctioned during battle.


Seacoast Development Group Inc. (SDG) was invited to participate in the MILSPEC testing of the Northrop-Grumman Corporation newly designed LED device in combination with the Rechargeable Battle Lantern;

After successful Fleet field tests, NAVSEA approved and accepted “…the LED Rechargeable Battle Lantern as an efficient and viable option for emergency/damage control lighting in the Fleet” (NAVSEA letter ref SER 9342/032 3 May 2004)


The Naval message R 141828Z OCT 05 COMNAVSURFOR provided “updated information for rechargeable Battle Lantern[s] assemblies, LED (Light Emitting Diodes) Battle Lanterns and retrofit kits for deckplate conversion of Battle Lanterns to rechargeable LED variant...", and identified SDG Inc. as a qualified vendor.


The industrial LEDs used in the SDG LED Assembly are rated at 100,000 hours of service life thereby effectively making the upgrade to the LED assembly a one-time purchase.


In accordance with manufacturer’s specifications and MIL DTL 16377-53C, an emitter controller allows the current draw to be adjusted in emergency conditions to extend the available illumination of the LED Assembly.


SDG is an authorized vendor for the LED upgrade kit for the rechargeable battery conversion kits.
