LightShip, a good little sucker
The first LightShip I tested had rather stiff and ineffectual suction feet and kept falling off the south window I stuck it on so that its little solar panel would charge up its Ni-Cad battery (no doubt the winter chill coming through the glass didn’t help). Then one last fall killed it dead. But that’s how I found out that SolLight had upgraded the suction cups, and now test unit #2 is stuck firmly to my office window and working like a champ. You can switch between red and white LEDs, and there’s even a light-actuated off switch if you want to just leave the sucker on all the time. At $15 a piece, less in volume, I’ve got to believe that lots of LightShips are going to go boating. There’s more detail here and, by the way, the SolLight bottle lamp I tried almost two years ago is still working fine.
