MiniInTheBox offers the 4-LED Solar Outdoor Path Spot Lamp 4-Pack in Cool White or Warm White for $19.99 with free shipping. That's $40 off list and the lowest price we could find. It features four LED cells and can be placed flush with the ground.
If I had any confidence these would survive longer than 47 days, they'd be interesting. Gave up on cheap solar landscape lighting long ago. Too many failures.
