Finally modern bulbs that advantageously replace the "low-consumption" and especially the "tungsten". Powerful Light of good quality, the colors are not altered. The power lighting would be even a tad higher than announced. No heating time, immediate maximum power. All for a super economical consumption between 5 and 7 times lower than the old bulbs! A small problem concerns the opaque base side base, which the luminaire type, could possibly somewhat limit the lighting in that direction. However, I highly recommend this new technology.
