Recently, Westinghouse is launching a new lineup of LED-backlit LCD TV that ranges from 24 inches up to 55 inches.

Starting at $299 and available in the third quarter, the 24-inch LD-245 is a 1080p model that the company says consumes less energy than a 40-watt light bulb.

Westinghouse also has a pair of 26-inchers—the 720p LD-265, due in June for $329, and the 1080p LD-268, available in July for $379. It has a similar double-shot of 32-inch sets, with the 720p LD-325 coming in June for $449 and the 1080p LD-328 shipping in the fourth quarter at a still-to-be-determined price.

There’s only one 42-inch TV, the $799 LD-425, as well as a single 46-incher (LD-46F970Z) and one 55-inch set (LD-55F970Z), neither of which is priced yet but will be ready for the holiday shopping season. These trios of larger sets also possess 120Hz refresh rates.

Westinghouse says its entire LCD line will be LED-backlit by the end of 2010. But don’t be surprised if others join them by some point in 2011.
