The Naval Sea Systems Command (NAVSEA) provided additional details including the new fixtures' 50,000-hr lifespan compared to the 1,000-hr for the incandescent globes and 7,500-hr for the fluorescents they replaced.
The ship is expected to save more than $50,000 per year using the new lights. Savings are expected to exceed $100,000 per ship per year when the scope is expanded to include T12 fluorescent fixtures.
NAVSEA also reported that, in early 2012, the USS Preble (DDG 88) is expected to receive the same fixtures as well as LED lamp replacements for the ship’s two-foot fluorescent fixtures, which are the most common lighting on DDG 51-class ships.
“The 600 LED fixtures Energy Focus provided include fixtures using our IntelliTube single LED waveguide technology to replace fluorescent berth lights as well as a range of advanced LED globe lights to replace existing incandescent globe light fixtures,” said Roger Buelow, Energy Focus CTO.
“Energy Focus has also received an order to provide its newly developed IntelliTube replacement LED tubes to retrofit both the USS Chafee’s and USS Preble T12 fluorescent fixtures, the second Navy ship to receive all-new LED lighting. The cost savings are expected to be even greater since the fixture doesn’t need to be replaced.”
In a separate announcement, Energy Focus stated it has completed a revolving secured line of credit of up to $4.5 million with Rosenthal & Rosenthal, Inc. This new agreement is a three year secured revolving line of credit to which Energy Focus may borrow up to $4.5 million, subject to periodic adjustments based on company assets.
