We picked up one of these sweet little lamps (Fatboy's Edison the Petit) this week to use on top of the aft closet in the boat (and anywhere else we want...it's portable!)
It's LED, has three light settings, is rechargeable, and has a whole bunch of cute lampshades (called Cooper Cappies) to give it a bit of personal style if you so desire. The light will last unplugged for 6-24 hours (depending on the light setting) before needing a recharge.
Here's Edison with the Mr. Orange Cooper Cappie:
Can't wait to try it out on the boat! This would be great for Airstreaming as well. Keep it on the dinette table charging, then take it outside to the picnic table for a romantic lamplit dinner!
