I already have the 10w version. This is a good solid work light it can be used at work, home, car or camping, fishing ect. It took about 2 hours to charge and the first time I used it for work it lasted a good 4hours. The charger has a LED light to indicate when charging (red) and when charged (green). It has a solid frame to it. It makes a great emergency light in power cuts.
Do not leave it on charge all the time this could lead to damaging the charger by over heating it.
