The G4 bulb and the GU4 bulb are low-voltage with pin bases, but with some small differences. If you are looking for information about either of them, for example, to switch your halogen lighting fixtures to LED technology, here is our guide to choose from the products available in this category in our online store.
Here the difference is quite small, but to be taken into account all the same! First thing to know however, the G4 and GU4 bases are both equipped with pimples.

Brief aside about MR11 reflector: this device enables any small size LED light bulb equipped with it to provide very good brightness.
Be careful not to confuse GU4 LED or G4 bulbs with G9 bulb, which is also very small in size and capsule or bulb shape.
You don't need to have any DIY or electrical knowledge to install or change a G4 LED or GU4 light bulb. For a change, simply pull out the existing bulb to fit the new one. Same thing if you have just bought a new light fixture, just push the bulb into the slot provided!
The G4 bulb is small and compact. It is used to equip floor lamps, tables, lamps, wall lights, hangers, kitchen hoods or shelves. It can also be used for accent (decorative) lighting in the living room or bedroom.
The GU4 bulb is bigger and equipped with a MR11 reflector. It is used to equip recessed ceiling spotlights and interior cabinet lighting.
When it comes to LEDs, we no longer talk about power in watts, but about color temperature, which is expressed in degrees Kelvin. As for lighting intensity, it is expressed in lumen. Generally speaking, G4 LEDs and GU4s deliver cool white, warm white or daylight luminosity, to be adapted to the room to be illuminated.
