Abstract
A method of lamp assembly that etching a glass tube body to increase a texture of the surface of the sidewall of the glass tube body, the sidewall of the glass tube body enclosing a hollow interior; and positioning a circuit board including a plurality of light emitting diodes (LEDs) within the hollow interior of the glass tube, wherein the increase in the texture of the surface increases the light diffusivity of the glass tube body.
