Led G4 transformer

[Joe 2017]

Good morning

Which transformer driver do I need for LED / watts?
(Many in difference Watt)

Can someone please send me a link on eBay or amazon, please

my current one is for halogen

Which G4 watts bulb is suitable

I have taken a picture of my current transformer
My current light has 8 halogen bulbs

1st pics shows current transformer
2nd pic is the light I have
3rd pic would this be suitable for 8 led G4 bulb
4th pics wattage of bulb 3 or 5 w

Any help would be appreciated

Thanks

You just do the maths 8x3w or 8x5w which one is lower than the 30w driver shown ?.
The driver W must always exceed the total lamp W

The old toroidal transformer

only has a maximin output, it does not care how small the output is, it will still work. The switch mode power supply, often called an electronic transformer

even if it is round, have a lower limit in this case

35 watt is the lower limit. But the newer models

today can go down to zero as seen in the picture. But the second problem is unlike the old toroidal transformer the output is not 50 Hz, and is often in the kHz range, which with a diode and an LED is a light emitting diode, it can become a transmitter, and many have in the instructions a maximum length of extra low voltage cable which can be used.

So the way around this is to use DC, but many 12 volt LED lamps state 50/60 Hz, as to if using DC will cause damage one can only guess, it seems unlikely, and the electronic transformer is not 50/60 Hz anyway, personally I have moved to low voltage (230 volt) but the lamp is designed to use quartz halogen bulbs, changing to non recommended bulbs, will always have some problems. But I would use the Varilight electronic transformer, mainly as it is about the cheapest option.

Thank you so much for your help.

Will this driver be suitable

I will probably get 5w * 8 bulb= 40w
Or may get 3w * 8 bulb =24w

Does it matter if total w is under 48 or only 24w

If I order this driver would this work please

I trying to be more energy efficient

 

[333rocky333]

Yes thats fine,the 48w driver will run fine at just 24 watt, make sure the lamps you buy state they will work on DC like the ones you originally posted,

thanks for all your help

1st pics shows current transformer

Why do you post pictures "upside down"?

It may not be a "Current Transformer"
but
it is an existing transformer.

2nd pic is the light I have

(Presumably, the new [non halogen] luminaire !)
The label on the nameplate of this indicates that this "device" has an "Input" of 240 V 50 Hz -
hence
no transformer is needed.

Seemingly, this device will have the Switched Mode Power Supply (SMPS) included.
to create the required 12 Volt (from the 240 V AC Supply) for any G4 Lamps - up to a maximum of 8 at 10 W,
as indicated on this label.

but

Oh don't confuse @Joe 2017 OK, a bit of clever English, next you will be saying a current transformer turns currents into raisins?

The device transforms the voltage, and also transforms AC to DC, how it does it does not really matter. And yes the device show will work.
