Light emitting diode tube lamp including a glass tube body composed of a self diffusive glass composition

A method of reducing the incidence of hot spot patterning in light emitting diode containing lamps comprising:

• alloying a base glass composition with an optically diffusive agent selected from the group consisting of lithium borosilicate, titanium dioxide, antimony trioxide and a combination thereof;
• drawing a glass melt of the base glass composition with the optically diffusive agent into a tube geometry to provide a glass tube body;
• and
• positioning at least one light emitting diode (LED) within the hollow interior of the glass tube body, wherein the optical diffusive agent alloyed with the base glass composition increases the light diffusivity of the glass tube body in which the at least one light emitting diode is present to substantially eliminate the incidence of hot spot patterning in the glass tube body from said at least one light emitting diode illuminated within the hollow interior of the glass tube body.
