What's dimmer, less energy efficient, and warmer than fluorescent lighting? If you guessed Edison bulbs, you'd be correct. I realize this isn't the best sales pitch, but take one look at these things, and you'll see why they sell themselves.
For under $10, this 25-watt Edison Bulb screws right in without the need for any attachments or adjustments. This bulb features an ultra long-lasting life, and fits all standard home lighting sockets!
