Daisenko 300 Electric Penlights are currently Lumica's top of the line Penlights. 

With up to 24 programmable colours, there's a colour for every one of your favourite idol. There's even a hot button at the back for fast colour switching to a preset colour.

To turn on and off the penlight, press and hold the center button. You can then cycle the colours by pressing the left and right arrow. The new colour will preview in the center button and when you press the center button again, it will switch. 

An alternate mode is to turn on the penlight from the back hot button. This directly changes your colours when you press left and right now instead of it only showing the preview.  

To program the colours, hold both arrow button to enter the programming mode and follow the instructions. 

Comes with AAA Batteries ready to go immediately.
