Powerful lamp
This lamp has a faily narrow beam that will easily light up the hedge on the far side of a field. It also has a much wider " spill" which is well defined for local purposes. The chargers ( mains AC and 12V ) supplied are specified at 9 volts and the connectors are standard USB. Before connecting to other devices I would need to check that 9 volts is acceptable. For some users the inability to vary the width of the main bean may reduce the lamp's appeal.
