Lamp holder e40
This type of lamp holders are the most suitable for industrial use, which needs greater resistance.
Something that characterizes the E40 is that they have a great resistance to higher temperatures and are also able to hold much larger bulbs and greater power than conventional lamp holders.
They can be adapted up to 39mm measurements.
Lamp holders B22D and B15D
We are facing an equivalence that occurs both in France and in England, their particularity is that they have a personal bayonet shape.
This type of lamp holder needs a quarter turn to be able to hook the bulbs into it.
The B22D lamp holder is equivalent to 26mm and the B15D to 17 mm.
Lamp holders G4, G6.35 and GX5.3
This type of lamp holder stands out for being ideal for both bipin or two-pin bulbs, that is, they adapt perfectly to the halogen bulbs of a lifetime.
All these types of lamp holders work at low power as a characteristic of them, and differ from each other types, due to the separation distance that exists between the two pins.
