Polymer light armature

An armature for an illuminant, comprising:

• walls formed by an armature composition, wherein the armature composition comprises
• an armature polymer, wherein the armature polymer comprises
• 35 to 50 wt % of the bromine-containing polymer based on the total weight of polymers in the thermoplastic polymer composition;
• and
• 10 to 65 wt % of the siloxane-containing copolymer based on the total weight of the polymers in the thermoplastic polymer composition, wherein the siloxane-containing copolymer comprises a first repeating unit, and a poly(siloxane) unit having the formula:
• wherein R is each independently a C1-C30 hydrocarbon group, and E has an average value of 5 to 200;
• and
• 10 wt % to 20 wt % coated titanium dioxide;
• and
• greater than zero to 0.001 wt % carbon black;
• wherein the weight percentages are based upon a total weight of the armature composition.

An armature for an illuminant, comprising:

• walls formed by an armature composition, wherein the armature composition comprises
• an armature polymer, wherein the armature polymer comprises
• a siloxane-containing copolymer in an amount effective to provide a total of 0.2 to 6.5 wt % of siloxane units based on the total weight of the polymers in the thermoplastic polymer composition;
• a bromine-containing polymer in an amount effective to provide 9 to 13 wt % of bromine, based on the total weight of the polymers in the thermoplastic polymer composition;
• and
• optionally a third polymer, wherein the wt % of the siloxane-containing copolymer, the bromine-containing polymer, and the optional third polymer, are based upon the total weight of the armature polymer;
• and
• 10 wt % to 20 wt % coated titanium dioxide;
• and
• greater than zero to 0.001 wt % carbon black;
• wherein the weight percentages are based upon a total weight of the armature composition.
