Explore the versatility and benefits of MR16 spotlights to enhance your lighting projects and create striking visual effects. They are also energy-efficient and long-lasting, providing cost-effective and eco-friendly lighting solutions for both residential and commercial spaces. The LED light bulbs we sell operate on a UK standard 240V AC, and the light bulbs have a built-in transformer to change this 240V to the LED required voltage. As with everything, you need to guard against paying peanuts for a product that doesn’t feature the latest technology or is made with dud components, while still getting value for money. As this comes with a +10% tolerance, electrical equipment with a stated voltage of 240V is still fine to use on standard UK mains circuits.

LED Driver Transformer 240V - 12V Including MR16 Connector

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. Hi I have just bought an optimyst stove with four 12v 45w bulbs giving a glow and false smoke effect- obviously running through a transformer. Look more closely and you’ll see that MR16 bulbs use a 12-volt, bi-pin base — two thin prongs that you simply push in. Because a typical halogen spotlight bulb maybe 35W-50W in power, but LED is only 5W, if the driver is not suitable to supply power for a 5W light bulb, then you may run into problems.

As a typical LED MR16 spot light bulb is only 5W, then three of these will equal a load of 15W which is outside the scope of the rating of the transformer. I'd appreciate some help to figure out a) what went wrong, and b) what I need to install them properly. This manifested as visible light flicker and dim light output (dimmed to 0 lm after approximately 10 minutes). Yes those LEDs aren't cheap, but they include both the holder itself and the LED bulb (which I don't think you can change). MR16 LED bulbs draw a significantly reduced amount of power compared to halogen bulbs; therefore the load is not sufficient to run from a traditional halogen low wattage transformer, this means a replacement MR16 LED Driver/Transformer is required.

I am building a wall cabinet with downlights in the shelves, for which I would like to use MR16 LEDs. For example, a 40VA transformer can handle up to 40-watts of electrical equipment, while a 10-60VA one can carry between 10 and 60 watts worth.

Using a scope the "AC output" was seen to be a rounded off square wave with a frequency in the kHz range. In addition, the chopped waveform may cause radio interference if the cables to the lamps are too long. The high frequency switching cycles are seen to stop and resume at irregular times within the 100 Hz wave envelope. He is now going to replace the MR16 bulbs with GU10s to get around the transformer issue and obviously moving to LED will also result in considerable energy savings for them! You don't require a driver, a driver should be built into the MR16 package which controls the current to the LED's there are some incorrectly labelled drivers which regulate voltage rather than current, however there output is DC.

You can get both DC and AC MR16 packages, but the DC type tend to be much more expensive, they have better quality drivers built in and can often work on a voltage range of 10 to 30 volt, they are designed for caravans and boats where the battery voltage can vary, so the ones bought in Lidi and Screwfix are normally AC. Norman is correct – the transformer in the fireplace is not designed to work with LED’s – many transformers need a minimum load to work, such as 50W, which is fine when you have two 28W halogen light bulbs installed.
