Vizio, Panasonic, Toshiba and RCA, and other LED companies are paving the way for CES to tap into their LED market.

Vizio is working on its line of LED bulbs for the U.S. which the company says will have a "Vizio price." Panasonic already manufacture LEDs for Japan and Toshiba started selling its A19 LED through BestBuy's Web site last month.

RCA said at CES that it will manufacture LED bulbs as part of a larger home theater announcement. It developed a "chip on a board" that uses a single efficient LED light source, rather than several smaller ones. That design optimizes the energy efficiency of the bulb, said Bob Hatefi of RCA licensee BDC in a statement.

Dedicated lighting companies are also going to be at CES. For Switch Lighting , it will be showing off its line of LED bulbs.

Additionally, like the TV and thermostat, LED bulbs are starting to become network-ready. Marvell introduced a wireless chip set designed to make commercial LED fixtures controlled from a single point.

Despite it’s a tendency that multiple lights is being able to be controlled from a tablet or smart phone for smart-home enthusiasts, the added expense of wireless networking in LED bulbs, which already cost between $15 and $40, means it may be a while before we see low-cost networked LED bulbs.
