Theta Pro is a battery-operated and rechargeable portable table lamp with an iconic profile reminiscent of a hotel call bell. It is equipped with a memory function which retains the light level and color temperature to the most recent setting each time it is switched off and on. The lamp has a multi-function control knob on top of the metal head that can be used for dimming and continuous tunable color temperature from 2200K (candlelight) to 3000K (cool white). Matte White, Matte Black, and Rust finishes are suitable for indoor and outdoor use. Each lamp comes with its own contact charging base.
