They will have a transformer either in the ceiling or light fitting.
Convert low voltage halogen to led.
You certainly can convert your low voltage lighting to outdoor led lighting.
Shown are g4 g5 3 g6 and g8 bulbs in both led left and halogen right technologies.
Because they operate on ac rather than dc you don t need to use a special led driver.
Led lights have a high resistance to moisture which prevents them from shorting out in places where water would normally accumulate.
The benefits of led conversion.
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 they are low voltage pins it s a bit more complicated.
You should be able to find this on the body of the transformer itself in the form of a va number.
Splice low voltage landscape wiring with weather proof wire nuts.
Since low voltage lighting uses 24 volts or less you can simply swap the existing bulb for an led equivalent bulb.
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.
