You don't have LED drivers with GU10 Lamps.
Not technically correct, all LED have drivers, but often the driver is part of the lamp package, with both 12 volt and 230 volt lamps, the driver is built in, external drivers are only required when the LED is classed by the current it uses, so a 340 mA LED will need a driver, a 12 volt LED does not, it is built in.
However the lighting industry seems to have a problem with names, be it driver, transformer, or ballast, they call new products after the old product it replaced, so you get electronic transformer which is really a power supply, it contains a transformer, but also has a lot of electronics which change the frequency of the output and control the voltage far better, but also often has a minimum output which a simple transformer does not, the electronic ballast is the same the simple wire would device is replaced with electronics, in both cases it has caused a problem with LED lamps as often they will not work with the electronic version, as to driver I have never worked out why the lighting industry calls a simple voltage regulated DC power supply a driver, but they do, also the current regulated power supply is also called a driver, which is correct, but the net result is you have to read the specifications the names mean very little.
Also of course even the name lamp, traditionally the lamp fitted on a spigot on the wall, inside the lamp you had a wick, or mantel, or a bulbous electrical device, bulb for short, but not all the electrical devices were bulbous in shape, we also had tubes, in the auto electrical industry the fitting has always been called a lamp, so order a head lamp and you get the reflector and glass minus the bulb, but house bashers have often said bulbs grow in the garden the bulbous thing with bulb written on the packet is a lamp! Which is of course daft, but call the whole unit a fitting, a lamp, a luminair, there is no word to cover all the replaceable bits inside the device, we have projectors, tubes, bulbs, wicks, mantels depending on fuel used, and to go into a shop and ask for a folded tube compact fluorescent is a bit of a mouth full so the industry actually called them a lamp, or CFL for short (compact fluorescent lamp) and with LED (light emitting diode) this is technically the bit inside the bulb, the chip, the bulb also contains the driver, and the base to connect it to power, and we hope some cover so we can't touch hot bits or anything else that will give one a shock.
But the language problem of the lighting industry means it becomes hard to use English to describe what you want, looking at @someone-else post, I think my box of tricks is technically a multimeter, it measures resistance both with over 250 mA for low ohm reading, and with 500 volt for insulation resistance, another one measures time and current so I know if the RCD is working correctly, and a further meter reads out in impedance and prospective short circuit current, although likely it measures volt drop under a set load. All technically multimeter, and all essential for the electrician, but non of the things they measure can be done with what we call the multimeter.
This is what happens when you marry a student of English, you realise why politicians like it.
