We have finally arrived at point in time when LED’s are at equal or less cost of the compact fluorescent, curly bulbs. This is a major achievement as LED’s last much longer, are again, much more efficient than compact fluorescents and contain no mercury which requires special handling when recycling.
When we started working and living with solar systems 30 years ago we had no choice but to use incandescent bulbs. Mr. Edison’s revolutionary bulb though was eight times better at producing heat than it is at producing light. So if you want to keep that pump house from freezing or warm those chickens you have the right bulb. But otherwise it’s time to cycle these antiques out of your home.
When compact fluorescents arrived on the scene, we were a
ble to order these at 12 volts DC and these bulbs lasted for decades. Then they became available at 120 volts AC, the kind of power we all use in out US homes. Then overseas manufactures reduced the cost and quality of some compact fluorescents. I have had feedback from too many that CF’s only last a year or so. Bummer, as the major manufactures such as Sylvania and GE still produce CF’s with excellent lifespans. Our local utility was even moved to purchase a cheap brand of bulbs and send them out at no cost to the consumer. Never mind that the CF’s embedded energy to produce makes them a negative even after their increased efficiency.
So long live the LED. Maybe these will be nick named as more true “Obama Bulb” as the times, they are a changing.
