SO they decided to get rid of incandescent bulbs. I guess I should call them lamps officially, but bulbs will do. Other than specialty bulbs like rough service or decorative types, the 100 watt are gone, I can still buy 60-40-25. But they came up with the CFL lamps. Those spiral (helix?) tubes on a screw in base. They seems to work well enough and I got a lot of light for less electricity. The last thing I am is an early adopter. But I got OK with CFLs. I bought "100 watt equivalent" CFLs, which used I forget, 23 watts maybe?
There are a FEW halogen bulbs. Like incandescents, but a little more efficient. But I think that is the hot filament folks just hanging on for dear life.
Of course LED lamps were coming along, but they cost like $50 for a damned bulb. They told me that over 30 years, the thing would save me X dollars on energy cost. OK, but I have to buy all 30 years worth up front. Hell, I;ll stick with the CFLs.
But I went to the store the other day... no CFLs to be seen! I looked all over, noted the LEDs had come down considerably, but was surprised that CFLs had been blown off the market that fast. Wide variety of LED lamps. And indeed a few cheap ones at lower wattage equivalent, like 40 watt. My 100 watt equivalent seems to work - makes light.
Technology is moving even faster than I thought.
