I've inherited a pretty poor quality garden light kit that runs off a 12V/2500mA AC transformer. It supports x6 lanterns which each have a measly 5W halogen bulb. Barely illuminating anything.
If I swap the bulbs out for LEDs I figure I can have a 200Lm or more while easily staying under the maximum 30W load on the transformer.
My question is will they work and what exact specification would I need? I've seen various models some consuming between 1.2W to 2W. Is there any danger this is too low? Are all G4 capsules designed to run off low voltage AC transformers designed for halogen bulbs?
