LED bulbs are environmentally friendly as they are considerably more energy efficient than traditional bulbs.Whats in the box?
A little extra light on my documents when working on my laptop but have used it for lots of other things also.
You might need to rotate the batteries around a bit to get it to be on but other than that its great and really super bright and easily lights up my entire desk from 5v USB!It says 6v input but i'm guessing thats just a maximum.it has 3 light modes when you push the switch.
I like this clamp light very much.
The only negative is the clamp is made out of plastic and can come loose if you put too much pressure on the lamp when moving it, but it does a good enough job since the light is so light in weight.
It has different levels of brightness, but I have only used the brightest one for my work.
I bought one and liked it.
So I bought two more and the next two flicker when you turn it on.
I've tried several outlets and can't solve the flickering problem.
The concept is good, and light (using USB cord) is great, but on battery mode it will not work unless I hold the battery cover and push down.
I tried to put something (bubble wrap) on the batteries in case that would help the cover make the connection, but it doesn't work.
