2.2 showed high power round luminaire glass

With 3.3 float borosilicate glass, due to the hardness and poor flatness of borosilicate glass, we use our self made rolling equipment to keep the high precision, no edge collapse and no scratch, the dimension tolerance is +-0.1mm. through scientific cutting, rolling, chamfering, cleaning and special tempering process to ensure the surface and internal quality of borosilicate glass.

Light transmittance up to 90%. Long time working temperature up to 450 degrees C, thermal shock resistance below 270 degrees C.
