LED Transformer Wiring

[Geoff Lane]

I notice that LED transformers refer to wiring bulbs in series, unless I am misunderstanding it.

I thought devices had to be wired in parallel to receive the correct voltage.

You wire then in series to receive the correct current. ;-)

Thats why its better to refer to them as drivers, the ones linked to in previous post are Constant Voltage and you would wire 12V LED lamps in paralel.

Constant Current drivers , as name implies keep current cinstant and vary the voltage, these are used with big LEDs and the LEDs themseleves are wired in series.

What kind of lamp you got?

I'm merely looking to replace some GU5.3 lamps with lower wattage LEDs.

My transformers cannot supply the low current so I am exploring options.

Although the energy saving is attractive it is more the cool bulbs in loft space that is appealing.

Replace the eletronic transformer with a toroidal, they're happy at any load. If you're not going to revert to halogens you could also use an ex-appliance 12v transformer, just needs enough rating to power the LEDs.

Torrodials have apalling regulation unless fully loaded, 20% over rated voltage ain`t uncommon.

My problem at the moment is I have 5 halogen bulbs each with its own transformer, can't get the the wiring to see what route it takes.
