Outdoor garden lights flickering
We have just installed new bollard LED garden lights each with a 3amp capacity on a 30watt out put transformer . The garden cabling used is 4.39mm more than recommended, we installed 6 lights = 18watt output but the lights would not work, when I removed three of the lights the others came on but were flicking.
Can anyone suggest a solution ie transformer not strong enough ect

You are saying "...6 lights = 18watt output..." which I believe is incorrect if your lights are 3 amps. Your math only works if your transformer and lights are 1 (one) volt. Watts are not the same as amps so you need to know the voltage to do the math.

Does sound like your transformer is not up to the task.
What is the required voltage for the lights?
Are they AC or DC?
What is the wattage of each LED and/or amperage? Usually they show the wattage.
Did the transformer come with the light set or did you make the set up with different items?
If you purchased the transformer separately then look carefully at it's specs.
Could be the output voltage is OK with no load but as soon as you put a load on it the voltage drops.

Yeah I would just install a 250w or 300w transformer...use these all the time at work with our azt led uplights. Sometimes we try to get away with installing ittle brick 75w transformers but the lights still may flash. These 250w and 300w transformers do not have a timer built in however, one would need to be installed nearby and it takes more know how to do the proper setup

A 12v 3A transformer is about 30 watts.
6 lights at 18 watts sounds like 3 watts a fixture which could be correct.
Could be an AC power supply with DC required fixtures.
