Oak Leaf via Amazon offers the LuminWiz PAR20 LED Flood Light Bulb 4-Pack in Soft White for $15.99. Coupon code "PU2N74EG" cuts that to $12.99. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it costs an extra $8.75.) That's tied with our mention from last week, $37 off, and the best price we could find. Each 8-watt bulb can replace a 50-watt halogen bulb, is dimmable, and has a 25,000-hour lifespan.
