So I'll just wire in brown to live and blue to neutral and wire out the two wires to the lights on using the first two output terminals. I currently have down lights with Osram decode 51s (12V 50W) halogen bulbs. Each light has a dimmable 60VA transformer connected. Could you please advise on a suitable replacement dimmable LED bulb?

MR16 halogen bulbs with LED bulbs Replacing GU5.3 MR16 halogen bulbs with LED bulbs

Not entirely accurate as in greece and eastern europe you can get mr16 fitting spots that use 230v and can be replaced with mr16 230v leds.

12VAC Electronic Transformers and LED Drivers

Many MR16’s & G4’s are sold as 3 on a transformer. If you have several MR16’s say 4 sets of 3 (12 total), could you simply connect all 12 new LED bulbs to 1 transformer (assuming that all 12 now draw the load required for 1 transformer)? Beam angle is measured in degrees. A wider beam angle covers more space with light. Your choice of beam angle, like colour variant, is completely down to you. As a guide, we’d advise using wider beam angles in living spaces where many people are gathered round. Narrow beam angles, on the other hand, are often used for decorative purposes or areas where you need focus.

Putting spotlights under the spotlight – GU10 versus MR16 Putting spotlights under the spotlight – GU10 versus MR16

You don’t always need to change the full fitting when swapping MR16 to GU10. My kitchen had the loose fly lead connections in the ceiling downlights. I rewired these to GU10’s mains and the old ceiling fitting still held the new GU10’s. You would not be able to do this on rigid fittings though! Three LED lights from different manufacturers were tested on each transformer including a Brightgreen DR450 7W This is personal preference. Some customers like to have one transformer per fitting or light strip so they can deal with any potential faults easily. It may not always be possible to use one transformer per fitting due to constraints such as space and cost, so keep this in mind when buying. However, many prefer to use one transformer to power a series of bulbs or light strips (maximum five metres on one transformer). As explained above, the transformer you require to do this depends on the combined wattage of the bulbs you’re powering. Also I presume a reasonably competent (non-qualified) person can do this (taking appropriate precautions of course inc. turning off the mains supply).The transformer you need depends on how many bulbs you want it to power timesed by the wattage. It’s also advised the total wattage of all bulbs combined doesn’t exceed 80% of the transformer’s wattage. For example, if you choose to power 4 x 4W MR16 bulbs (16W total) from one transformer, you’ll need a 20W transformer. If you want to power 4 x 6W MR16 bulbs, you’ll need a 30W transformer, and so on. Some electronic transformers have a minimum output, and also can end up being a transmitter with adding diodes, but there are no problems with a toroidal transformer so depending what type of transformer could be a simple swap. Yes, that's exactly it - 4 lights are currently run off a single ouput. Probably explains why it overloaded then! It was already wired that way before I moved in to this house. to their D900 Curve LED downlight. The voltage is approximately 36.5V (oscillating slightly on account of voltage ripple from the 50 Hz mains) DC. All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally. The purpose of the transformer is to reduce mains voltage (240V) to the desired level relative to the bulb being powered (e.g. 12V or 24V). Switching to LED - which bulbs require a transformer?

Bathroom lights are MR16 - can I just replace MR16 bulbs for the ones you've linked to without changing the transformer again? If so, is there a version of those bulb that I can use that look more like the tranditional MR16/GU10 shape - so they fit the existing light fittings? drop (the maximum distance is about 1.5-2m). While this could possibly be a factor for runs over 4m and incorrect wire sizes, 2m should not. MR16 LED spotlights come in different colours too. These colours are measured in Kelvins. The lower the Kelvin, the warmer the light, the higher the Kelvin, the cooler the light. You can choose from Cool White, Warm White and Daylight colours. Where you use these colours is entirely up to you. If you want an idea, many customers use Warm White for cosy living areas, Cool White for bathrooms, while Daylight offers a happy medium. You can read more about our post on colour options here to see how they could look in your home.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 MR16 LED bulbs is to find the transformer’s maximum load. You should be able to find this on the body of the transformer itself, in the form of a ‘VA’ number. This VA number will either be fixed, or it will be a range (e.g. 10-60VA). When replacing Halogen MR16 light bulbs with LED bulbs, it’s important to use LED bulbs of equivalent wattage to your existing halogen light bulbs. This will ensure that the transformer can still handle the load safely.
