You should be able to find this on the body of the transformer itself in the form of a va number.
Convert low voltage halogen to led.
Since low voltage lighting uses 24 volts or less you can simply swap the existing bulb for an led equivalent bulb.
They will have a transformer either in the ceiling or light fitting.
If you have low voltage halogen light bulbs installed with a transformer the first thing you need to do before replacing halogen mr16 light bulbs with led light bulbs is to find the transformer s maximum load.
If you re replacing low voltage mr16 50w halogens that have low voltage transformers the first option and potentially easiest way to convert to led is replace it with something like a philips 8w mr16 led they should operate from your existing transformers.
Some led bulbs like the philips master led range have in built.
Splice low voltage landscape wiring with weather proof wire nuts.
You certainly can convert your low voltage lighting to outdoor led lighting.
Replacing halogen mr16 light bulbs with led light bulbs.
The benefits of led conversion.
Led lights have a high resistance to moisture which prevents them from shorting out in places where water would normally accumulate.
Shown are g4 g5 3 g6 and g8 bulbs in both led left and halogen right technologies.
When switching to leds this can be a problem as leds need direct current and most led drivers are made for low dc voltage or high ac line voltage.
