This is an excellent light, when it works. giving a soft white light to th esubject. Is excellent on night dives as it does not take away the effect that you are on a night dive, as so many video lights can. The switch is not good and after three uses on holiday diving, it has developed a fault as there appears to be a loose connection. On the last dive holiday it worked intermittently and then stopped completely. At least it is still under warranty so I shall be taking it to the dealer shortly. If it wasn't for the unreliability problems I have experienced, I would have given it 5 stars.
