lamp transparent

i’m trying to model a clear glass transparent filament lamp
see pic

i;m using the mirropr and transp panel not the ztransp

i’v set the variable see the pic but the result in blender are not great at all
so if someone could help with this id appreciate it

now i can do it easily with yafray - it’s very transparent and nice

but i’d like to do it it blender too which seems tob e more difficult to achieve

can someone helop with this

Thanks

the gloss must be set close to 1 for mirror and transp
that makes it totaly transparent like in yafray
