Free UK delivery on orders over £120

These G4 1.5w LED Dimmable Bulbs (12v) are the perfect replacement for traditional halogen bulbs.

Unlike many other G4 LEDs on the market, they are almost an identical size to a traditional halogen bulb at 9mm x 26mm (35mm including pins).

These LED dimmable bulbs are designed to work best when paired with a low load transformer.

I purchased these G4 LED Bulbs and the all Flicker?   

The transformer your light fitting is using is designed for Halogen lamps.  As LED lamps use a lot less power, the energy consumption is outside the working range of the transformer (Below the minimum load).

You should consider changing it.  Example: 10 x 20W halogen (200w), 10 x LED G4 (15W).  Transformer working range is probably 50W -300W!

They don’t dim properly and flicker at low levels?       

Like the Transformer, dimmer switches have a working range. Usually something like 50W – 250W, therefore with LEDs the load is probably below the minimum working range .  You should change you dimmer switch to a load load LED dimmer.

These lamps may work perfectly with your fitting, however it maybe one of both of these causing the issue.

We have some facts about LEDs that may interest you here.
