The M-Edge white e-Luminator booklight features touch-activated power settings that allow users to control the brightness of their booklight. With this light's low, medium and high light intensities, you can tailor the illumination to your personal preference. An enhanced super-bright LED light bulb provides ample illumination for the e-reader screen, while a mirrored reflector and optical quality lens disperses the light uniformly. This LED booklight features a fully adjustable steel neck for fine-tuning the light's position, and the slim support arm slides into the convenient, sewn-in pocket featured in every M-Edge jacket. The e-Luminator Touch for eReaders includes a sleep timer that will turn off after 60 minutes of inactivity for maximum battery conservation.
