Toshiba Lighting & Technology Corp and Panasonic Electric Works Co Ltd respectively exhibited straight tube LED lamps compatible with the "JEL801:210" standard (See related article).

They were showcased at Eco-Products 2010, a trade show on green technologies, which took place from Dec 9 to 11, 2010, in Tokyo. The JEL801:210 was defined by Japan Electric Lamp Manufacturers Association (JELMA).

Toshiba Lighting & Technology will release its straight tube LED lamp in January 2011. By showing the LED lamp along with a 40-watt fluorescent lamp having an equivalent brightness, the company emphasized that their brightnesses are almost the same and that the light of the LED lamp is not "spotty."

Existing straight tube LED lamps tend to have such a problem because light is emitted from each LED element. This time, Toshiba Lighting & Technology developed a new method of diffusing light at the circumference of a straight tube LED lamp so that the light from white LEDs evenly spreads and does not become spotty.

Moreover, the company emphasized that, despite their similar appearances, straight tube LED lamps and fluorescent lamps have different shapes of bases and pins. The price of the new straight tube LED lamp is about ¥30,000 (approx US$357).

On the other hand, Panasonic Electric Works, which will launch a straight tube LED lamp Dec 24, 2010, in Japan ahead of Toshiba Lighting & Technology, showed the lamp being used as a ceiling lamp of its booth. The company emphasized the low power consumption of the lamp by displaying its wattage. Panasonic Electric Works has already received a number of orders for the lamp, it said.
