Oven Lamp 300°C High Temperature Resist Oven Bulb ST23
Oven Lamp usually need to be 300 degree high temperature resist, because it is used inside Oven, which is with high temperature.
However, 300 degree high degree centigrade resist oven lamp is with higher cost than ordinary oven lamp, and it looks almost same as ordinary temperature ovan lamp. So it is better to know the difference between 300 degree centigrade high temperature resist oven bulb and ordinary temperature oven bulb, the difference is as below:
1. The glass part and tungsten filament part is same, no difference.
2. Lamp base is different. There must be soldering point on top of the lamp base, because only tin soldering point can withstand 300 degree centigrade high temperature. However, because tin usually contains lead, it’s not good for environmental testing, we have to use Lead-free soldering wire.
3. The glue between lamp base and glass part must be full and enough for 300 degree high temperature resist oven lamp. Ordinary temperaturer oven bulb only has some glue on the bottom part of the lamp base, the glue is between lamp base and glass part. However, for 300 centigrade degree high temperature resist oven lamp, the glue must be applied all over the contact surface between lamp base and glass part, because high temperature does harm to glue, that is why the glue must be all over the surface and must be enough.
When you need to buy a 300 centigrade high temperature resist oven bulb, you must be aware of these differences. If you use an ordinary temperature oven bulb for a oven, the oven bulb usually has a much short life.
