- dragontamer 10y agoLEDs were expensive. From my experience, its "grassroot" old guys who just don't like the new "color" of LEDs. True, LEDs were invented decades ago, but the "proper color" ("Warm White") wasn't really available until recently. Now that LEDs are the proper color for internal homes, people are beginning to use them. They're still far more expensive than incandescent bulbs, so a lot of people (who don't run the calcs on their electricity bill) still prefer the older bulbs.
