This is what I used a while back in a project I was working on
#declare the Lights variable however high/low you want it. Just keep in mind
that this is a multiplier

#if ( Final )
        #declare Lights = 5; // Makes a total of 11 lights per TL-lamp
#else
        #declare Lights = 0; // Just 1 light for preview purposes
#end

#macro TL_Bak(OnOff)
union {
        box {< -25 , 0 , -500 >,<  25 , 70 , 500> pigment { White }}
        box {< -15 , 0 , -500 >,<  15 ,-25 ,-475> pigment { White }}
        box {< -15 , 0 ,  500 >,<  15 ,-25 , 475> pigment { White }}
        cylinder {<0,-25,-500>,<0,-25,-475>,15 pigment { White }}
        cylinder {<0,-25, 500>,<0,-25, 475>,15 pigment { White }}
        cylinder {<0,-25,-450>,<0,-25,450>,20 pigment { White } #if
( WorkshopLights ) finish { ambient 10 } #else finish { Shiny } #end
no_shadow }
        cylinder {<0,-25,-450>,<0,-25,-475>,17.5 pigment { P_Brass5 }}
        cylinder {<0,-25, 450>,<0,-25, 475>,17.5 pigment { P_Brass5 }}

honestly say what or how anymore
