About this deal

The LEDs are too far from the transformer, resulting in voltage drop (the maximum distance is about 1.5-2m). MR, which stands for “multifaceted refractor”, refers to the shape and design of the top part of the bulb. The number after MR refers to the diameter of the bulb in terms of eighths of an inch — the 16, in this case, means that the bulb is 16/8 inches (or 2 inches) in diameter. Driver should refer to a current regulated DC power supply, but often same name given to voltage regulated device, so you need to be careful. DPO2012B oscilloscope. A sample of LED lights was used on each transformer to assess it's compatibility and output

Another point worth noting… many spots produce ‘torch beams’ dark/light areas that are awful in kitchens. I’ve found that the smd LED versions give much better light spread.

Final thoughts – 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! When considering LED retrofit options for MR16/GU5.3 halogen downlights, the buyer should factor in not only light quality but transformer compatibility as well. series to give the necessary resistance for the transformer to work. All wiring in homes is done in parallel, never series. with your existing installation. The likelihood of compatibility between a 12V LED light and a 12VAC halogen transformer depends on a few factors:

The transformers' output voltage waveforms when powering a 35W Osram Halogen can be seen in the figures below. The 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.MR16 and GU10 spotlights are among the most popular LED spotlights around. The main differences between the two is that MR16s have a different base (fitting) which consists of two narrow pins. MR16s also run on just 12 volts, while GU10 spotlights have more flexibility and can run at 240 volts (which is more common in households). This means MR16s need a different transformer to convert the main supply to the required 12 volts. You have a range of different fittings to choose from. At LEDHut, we offer Fire Rated downlight fittings. These have been protected for up to 90 minutes and offer advanced thermal protection, preventing fire from spreading to ceiling, floors and loft space above. We also offer a Shower Rated downlight fitting which (surprisingly) are perfect for bathrooms as they guard against water entry. Both fittings come in different styles. Choose from white, chrome and brushed steel finishes depending on the look you want to go for (see below). The first thing you need to do is determine the existing type of transformer you have in your MR16 circuit. This will most likely be situated up in the roof above the light fittings – now in some circuits there is one transformer, but sometimes every individual light fitting has its own transformer. They tend to come in two varieties; the first is the older wire-wound magnetic transformers and the second is the newer electronic low-voltage transformer. Both work by stepping down the mains voltage (240v) to 12 volts, which allows the bulbs to function.

false. You must’ve had 1 bad ‘bulb’ (LED bulbs are called lamps, I think, and they contain many LEDs in each lamp). The LEDs in each lamp slowly fail and thus the light dims (30% failed LEDs is where they deemed to be dead, I think, or 70% ?). MR16 LED lights vary in complexity across manufacturers and model designs. The most basic 12V retrofit LED downlight will include the DC LED chips for the light source,

Why do I need an LED driver?

LED drivers' are electronic DC power regulators designed specifically for DC LED lighting. They are not suitable for 12VAC (halogen or LED retrofit) lighting. 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. 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)? Bulbs that operate on a lower voltage than 230-240V must be used with a compatible transformer when installing on UK mains circuits. The transformer converts mains voltage to a lower voltage suitable for the bulbs, ensuring they function as designed and preventing damage to the bulbs and/or light fittings.

The natural energy-saving properties of LED light bulbs means that they can offer the same brightness of a halogen equivalent, but using only a fraction of the power. A 5W LED spotlight, for example, can offer the same brightness of light as a 35W halogen spotlight. within a 100 Hz waveform. Despite the differences in the voltage waveform, all five transformers successfully powered the

The transformer you need for strip lighting depends on multiple factors, such as the length of strip, watts per chip and total wattage. LED strip lighting comes with either small LED chips or larger LED chips, as well as a variety of sizes ranging from 1m to 5m. Small LED strip light chips are marked “3528” and measure 3.5mm x 2.8mm, while large LED strip light chips are marked “5050” and measure 5mm x 5mm. Larger 5050 chips are brighter per metre than small 3528 chips. To calculate the total wattage of the LED strip you wish to power you have to do one of these simple sums: • 60 small LED chips: calculate 5 watts per metre • 120 small LED chips: calculate 10 watts per metre • 60 large LED chips: calculate 15 watts per metre You then need to add another 20% to avoid potential overload on the transformer. load input of the wirewound transformer can be seen to be a simple 50 Hz sine wave. In contrast, the electronic
