TopperSun via Amazon offers the
Minger 7-watt Light Sensing Bulb 3-Pack in Warm White for
$25.99 with
free shipping. At $8.66 per bulb, that's slightly less than the per-unit price of our mention from last week and $9 under the lowest price we could find for a similar 3-Pack, outside of other Amazon sellers. They feature auto on/off and 600 lumens.
