Our bulbs are with 320℃ high melting point and unleaded soldering tin, it won’t drop even the bulbs work in oven or other high temperature environment for a long time. The soldering tin on our bulb is flat and smooth, no faulty welded.
The clay inside the bulb base determines the torque, which is an important manifestation of the safety performance of the bulb. Our bulbs are filled full clay between the base and the glass, and the bulb base is firmly bonded by the clay after high temperature baking. The clay we use in our bulb is 600℃ high temperature resistant, it can ensure the bulb base won’t drop in high temperature working environment.
The bulb is built in double coiled-coil filament to improve the anti-seismic performance of the filament and ensure that the filament will not fall off during the transportation and working.
