cylindrical LED bulb

Toshiba lighting technology introduction of cylindrical LED bulb
Toshiba lighting technology released "E-CORE" series of LED bulb two cylindrical ( T ) product ( daylight and incandescent lamp color ). Brightness equivalent to 40W light bulb ( daylight color products to 600 lumens, incandescent lamp color products to 485 lumens ), rated power consumption for 7.4W. This is the first time the company launched T LED bulb.
Toshiba lighting technology plans to use the products to replace the cylindrical fluorescent bulbs ( D type and T type, D type for fluorescent tube exserted style, T shape with shade style ). The use of D type and T type fluorescent lamp apparatus with small size design, in many cases cannot install E26 lights in the ordinary LED bulb.
New product ( T - 7.4W ) can be fitted to the D type and T type fluorescent lamp special appliances (not including the insulation materials construction equipment ). Therefore, applicable to the lamp socket can be mounted laterally of the lamp ( DownLight ), and wall lamps and chandeliers, lamps and lighting equipment requirements of the overall brightness. In addition, can also be used for bathroom lights and other closed apparatus. But cannot be used with light modulation function and circuit apparatus.
T 7.4W product dimensions and Toshiba lighting technology D shaped fluorescent bulbs ( FED15 / 13-Z ), diameter 40mm, length of 109mm. Light distribution angle of approximately 300 degrees, also with D shaped fluorescent bulbs of the same. The product can realize large light distribution angle due to the use of a cylindrical inner surface reflection lampshade, and the LED light source is configured in the bottom surface of the lower position lamp design.
In addition, as a comparison object's FED15 / 13-Z brightness equivalent to general lighting using 60W bulbs ( 810 LM), than the T 7.4W products ( equivalent to 40W bulb to light ). Toshiba lighting technology said, will continue to develop T LED bulbs, future plans to launch the size and shape of the light distribution angle and D type and T type fluorescent bulbs with size, but also a consistent product.
T 7.4W two products will be sold from February 10, 2012. Suggested retail price ( including tax), incandescent lamp color ( model: LDT7L-G ) and daylight ( model: LDT7N-G ) are 5670 yen ( about 470 yuan). Heavy 125g, the rated life of 40000 hours. Sales target of two products together every year 240000.
