Thrifty and light - It is possible!

For years, I'm waiting for thrifty bulbs that emit pleasant and bright light. These LED spots I have found them. The 50W halogen spotlights in my lamps in the living room, kitchen and bathroom are now replaced by 7W LED. So I verbrate instead of 200 watts into each of 4 spots only 28 watts. And the best part: it's brighter than before! A pleasant light, not too cold, not too yellow, and not so far from my feeling the daylight spectrum. The conversion is at a unit price of 4.99 an investment in the future, but at least I do not have to buy me new lamps.
Now the dark season the next electricity bill can come as well.
