Lamp knowledge: How can you tell the true and false of the lamp?

How to distinguish the true and false of the lamp?

We can look at the following aspects from the following aspects:

Material aspect

The bulbs of ordinary incandescent lamps are easily rusted by white iron. The lamps of better quality are generally made of aluminum alloy, which is not easy to rust.

Filament aspect

A good light fixture is a double tungsten wire, a bad one.

Brightness

For the lamp, if the lamp is a one-time powder coating, the brightness is uniform after power-on, and the difference is artificially powdered, and the brightness is uneven.

Price aspect

Don't just buy a light when buying a luminaire, because quality and price are definitely proportional

Certification aspect

It depends on the right 3C certification and its content is reviewed.

Old and new

Novel products may not be mature in technology. Do not choose the latest ones when purchasing, but ignore the old models.
