The Panasonic LDAHV4L27CG LED bulb is the first in the world to use clear glass to show the light source. With its single filament it uses just 4.4 watts. The ultra long life LED bulbs can achieve a lifetime of 40,000 hours which is approximately 40 years (at usage of 2.7 hours per day).
Lighting designers will appreciate them probably also because most of us still love the sharp shadows created by clear tungsten bulbs. LED delivers 100% of the light instantly. So no need anymore to wait a warm up of the lamp. You can finally truly use it in a staircase or bathroom or wherever the light needs to be switched on 100% instantly. With same dimensions as the traditional light source, it can be used as a perfect replacement for incandescent light bulbs.
Feel free now to switch on or switch off the bulb anytime as you want. The Panasonic LED circuit enables almost infinite switch on & off cycles (100,000 times) without damaging the lifetime. Besides being A-energy rating, Panasonic LED bulbs are high in efficiency with 48 lm/W, a high lumen maintenance of 70% at end of life and a high colour rendering of 80%. Japan Institute of Design Promotion (JDP), Japanʼs only comprehensive design promotion organization, has released the results of the special award winners. The panasonic LDAHV4L27CG, among other 11 projects, received the gold award in the japan good design award 2011.
