We’ve seen some interesting examples of LED desk lamps, but the Greendix Lumileaf recently debuted by Sonelis Technologies takes top honors, by virtue of both its elegant design and the fact that it doesn’t come with a plug.
Housed within this lamp’s brushed aluminum frame is a 1.25W leaf-shaped solar panel, which harvests both direct and ambient light. Power is stored in a built-in 1800mA NiMH battery which then provides juice, after dark, to six 1.2 watt high-brightness energy-efficient LEDs–which, according to Sonelis, provide “ample light for any situation.”
As an added bonus, this desk lamp is waterproof, and was designed for use in both outdoor and indoor environments–in case, perhaps, you’d like to sit outside on a summer’s night with a good book. (An ambient sensor here automatically controls the LED’s operation, so this light comes on whenever it gets dark.)
Sonelis, which bills itself as “a solar panel distributor and design house that specializes in custom shaped mono/poly Silicon crystalline solar panels,” also points out that the LED lights in the Lumileaf are embedded directly into the solar panel. A design which common sense says would limit its effectiveness in a downward-facing desk lamp–but hey, LEDs don’t require much juice to stay lit.
