The Glossy material in Lux has two  parameters that have an effect on the reflectivity: 'uroughness' and 'vroughness'. They both do the same thing, but in different directions of the UV map.

Lower values make the surface more reflective. Higher ones make it less so.

If you use the Pose2Lux 'basic/Glossy' material you can control the '*roughness' values by entering a value into the Reflection_Value field in the PoserSurface. The value exported to Lux is the reciprocal, so if you use a value 0f 0.99 as in the attached example, you get uroughness and vroughness values of .01 (i.e. quite reflective)
