GU4 / G4 LED bulbs - the best selection according to Stiftung Warentest and customer reviews

G4 LED socket, Stiftung Warentest Sieger, bestseller 2018

G4 LED lamps or GU4 LED lamps have been in trend for the small two-pin connections for several years. LEDs have a long service life, do not consume a lot of energy and are more environmentally friendly than many other "energy-saving lamps". In this post I have put together the G4 LED light source test winners from Stiftung Warentest from 2017 as well as the bestsellers from Amazon with good customer ratings, reviews and an advantageous price-performance ratio (currently: 2018). So you can always find the best chandelier with base and Bipin base. 

Difference between G4 and GU4 pin bases

Both types of lamps have one thing in common: the 4 stands for the same type of pin-base lamp, the connections of which consist of two pins. The distance between them is 4 mm, which is the name given to the type designation. However, there is one difference between GU4 and G4 - namely the diameter of the pins / pins. Here are the values ​​so that you can buy the right spotlight for your lamp or spot:

  • Diameter of the pins on the G4 socket: 0,65 to 0,75 mm
  • Diameter of the pins on the GU4 socket: 0,95 to 1,05 mm

In addition, the thinner pins are more likely to be found on small lamps and the thicker pins on spotlights, i.e. round devices. Some of these also have a reflector that allows the light to be used as a spot.

The Amazon Basics LED bulbs for G4 sockets are current bestsellers. Both G4 warm white lamps and other LED bulbs as alternatives to halogen lamps are trendy. In the test by Stiftung Warentest, many scored well.

G4 / GU4 lamps in test: Stiftung Warentest test winner

A wide variety of products are regularly examined in the test magazine of Stiftung Warentest. These included lamps with G08 or GU2017 bases and two-pin bases in the 4/4 issue. The results from the G4 LED test ranged from a grade of 1,8 (good) to a grade of 2,9 (satisfactory). In the following I have listed the first seven places with different grades in the "Good" area. I have provided some of the products with a link to Amazon so that you can view or buy them. Others do not have this link because they either do not exist on Amazon or they have no or mostly bad reviews there.
