Lightweight, adjustable and good battery life

This set of 2 mini lamps hang around very convenient. They are all light and thus can be clipped on a book without feeling the weight. The clamp opening up to 4 cm, this leaves a good choice of catching points. I noticed the presence of a rubber pad inside of the clip, which avoids making marks on where the clip is attached.
Each antenna is completely malleable and remains in the fixed position. They are each equipped with 2 LEDs and a button on top. We can turn a single antenna choice, Led by one antenna or two LEDs on each for full power. The halo is restricted and can be directed perfectly into the desired position for discretion.
Without batteries, they are rechargeable by USB (cable supplied). I have not yet managed to empty the load, so the battery has a very correct term.
This pair of light antennas is handy to have a gentle but sufficient lighting for reading at night without boring spouse. I read a lot on the shelf with backlight allows me to read the night in the same way. Now I have the equivalent with these antennas for paper books ;-)
