In case you missed out on a similar sale earlier this week, Amazon will sell you a 6-pack of highly rated OxyLED soft white bulbs for just $12 right now with promo code OXYA1999. These put out the brightness equivalent of a 60W incandescent, but with only 9W of electricity each. Plus, many local utility companies offer rebates when you buy these things, so they should pay for themselves in short order.
Note: These bulbs aren’t dimmable, which isn’t surprising at this price, but just make sure you’re aware.
