All mains powered led bulbs require a transformer.
Do i need a transformer for led downlights.
The customer used to use halogen but has moved over to led.
This is because the higher voltage from the halogen transformer can damage the led and actually result in lower light output.
Basically pins need a new transformer and pegs do not.
If you are replacing existing incandescent 12v bulbs you will need to replace the transformer with a special led driver.
They had stopped working due to a faulty 12v transformer i ve just replaced the transformer with a constant voltage driver 1 25w but with any more than 3.
In some situations you ll need to replace this transformer with an led driver to regulate the voltage.
Mr16 and other 12v bulbs use an external driver.
But it s generally a good idea to install an led driver regardless.
Led strip lighting comes with either small led chips or larger led chips as well as a variety of sizes ranging from 1m to 5m.
When considering led retrofit options for mr16 gu5 3 halogen downlights the buyer should factor in not only light quality but transformer compatibility as well.
Hi guys quick question regarding 5x mr16 gu5 3 led bulbs in downlighters.
Transformers and led downlights mr16 halogen downlights require a transformer for each globe.
Halogen transformers provide much much more power than led downlights require.
Depending on the bulb type the transformer driver may be built in to the bulb casing or may be located externally.
Replacing your existing 12vac transformers in addition to your downlights can be costly and inconvenient making it important that replacement led downlights work well with your existing installation.
Most transformers drivers installed with halogen downlights are rated as either 50 or 60 watts or va.
Because they operate on ac rather than dc you don t need to use a special led driver.
This means that they are rated to supply lamps that draw up to 50 or 60 watts more than the energy they consume to energise themselves.
The purpose of the transformer is to reduce mains voltage 240v to the desired level relative to the bulb being powered e g.
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.
All led bulbs require a driver a special type of transformer to work properly.
They should operate from your existing transformers.
Otherwise you risk the excess power blowing the led.
