Recently, Panasonic Electric Works has released an LED lighting device to replace high-output high-frequency (HF) fluorescent lamps.

According to the company, the new LED lighting device has a brightness equivalent to or higher than those of HF fluorescent lamps. The CRI is 84. A high-efficiency model that is expected to embedded in a ceiling to replace two HF32-type fluorescent lamps has a designed luminous flux of 5,880lm, a rated power consumption of 60.6W on average and an efficiency of 108.3lm/W, which are approximately 14% higher, 31% lower and 27% higher, respectively, than those of two HF fluorescent lamps.

The company will release 68 models including straight tube models, rectangular-shaped models, etc that emit white, daylight-color, warm white, incandescent-color lights.

The new lighting device is equipped with an LED module using a ceramic substrate that has a high resistance to deterioration, a high heat radiation performance and a high reflectivity. As a result, its lumen maintenance factor is 95% after 40,000 hours of use.

The white and warm white models start to sell on Dec 1, 2011,and the other models are to be sold on Feb 1, 2012.
