What is different with this new expression model?
We have replaced the 3 AA batteries and the battery holder used on original expression models. Now a single, higher capacity Li ion battery is being used. It has a longer life than the NiMh in previous models.
New LEDs offer more brightess at all battery charge levels.
The light now turns off automatically after 8 hours to conserve charge for the next day. This new model has 30% more lighting time than previous Expressions.
