Amazon offers Prime members the Philips 60-watt Equivalent A19 LED Light Bulb 16-Pack in Soft White for $20.29. (Daylight is available for slightly more.) Order via Subscribe & Save to net free shipping. That's $1.27 per bulb and the lowest price we could find by $5, although we saw it for a buck less on Prime Day. Each bulb features a lifetime of up to 15,000 hours.

Note: Be sure to cancel Subscribe & Save after your order ships to avoid being billed for subsequent shipments.
