$halflambert_gbuffer_off is a material shader parameter for the VertexLitGeneric shader available in 
Black Mesa. This game provides $halflambert effect separately for new lights. It is activated by default (only if nr_lights_quality is 3 and higher and if $phong is enabled), that's why there is this parameter that allows you to turn it off. This effect looks pretty nice for objects that don't cast any dynamic shadows, such as viewmodel. However, this effect has a negative impact on objects and new lights with enabled shadows, also half lambert isn't physically accurate and is similar to how translucency works. The only good it really does is making up for bad ambient lighting. So this effect should be turned off. The parameter takes bool value (1 or 0).
