Do you use a battery operated craft light?

The committee are discussing  purchasing some battery operated craft lights for use at meetings and workshops.

There are a number available on the market and so it would be useful to know if any members have tried/use battery operated craft lights and whether they would recommend them for branch use. 

If you do have a view can you share it at the meeting on Monday and, if possible, bring one along and help shed some light on the subject.
