Multiple light fitting with LEDs

[Owd Oss]

I have a light fitting which takes 10 x 10w, 12v G4 bulbs and have recently changed to 1.5w LED bulbs but they are very dim. If I replace 1 LED bulb with a halogen bulb they all light to full brightness!! Any ideas how to overcome this please? The bulbs are cool white and I can't find a cool white halogen so this is not a good solution.

Many thanks

sounds like there isnt enough load for the transformer to work correctly

As previous poster probably not enough to load. You could either increase the wattage of the bulbs (lamps) or change the transformer in the fitting with a lower min wattage rating.

Or put the original bulbs back in!

hum... or buy a different fitting?

Not sure I agree with the idea of suggesting that the transformer gets replaced....

What about a capload across the output terminals?

What would your aversion be to replacing a transformer in a light fitting?

I doubt that would help, a resistive load would be more likely to cure the problem (as can be demonstrated by adding a single halogen lamp)

LED lamps are already presenting a capacitive load to the transformer so increasing that capacitive load won't help, adding a small resistive load does help.
