About this deal

Halogen bulbs claim to last 2000hrs (2 years average), but it’s more like 1000. Some GU10 LEDs claim 24,000hrs, but that’s an even bigger lie! However, the EU implemented a law in 2014 – LEDs now must last at least 6000hrs, so they last 3x longer than halogens, minimum (more like 6x longer or more)!

You may have bought or are thinking about buying some LED strip lighting or MR16 fittings or spotlights for your home. Either way you’re here to find out the whats and whys about LED drivers (or transformers). This handy guide will help you make an informed decision and give you the fundamentals you need when buying a driver. Why do I need an LED driver? Now the older magnetic transformers will work perfectly with LED MR16s. The issue is that the electronic low voltage transformers may not. The reason for this is that they need a minimum voltage to pass through them to operate; for example the transformer in my kitchen is 40w – 400w. Historically there were 6 50w halogen bulbs in the circuit – giving a total load of 300w. will work with. The fundamental difference between the two is that LED drivers output DC while electronic halogen transformers output Circle with X in represents the light. It doesn't matter which way round the 12V lighting circuit goes, and it would appear that it supports up to 4 lights. 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.Electronic 12VAC halogen transformers can vary significantly in design and consequently in how they respond (or do not respond) to different loads. 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? with your existing installation. The likelihood of compatibility between a 12V LED light and a 12VAC halogen transformer depends on a few factors: If you've got a Marcus easy-access savings account or cash ISA, you can easily boost your interest rate to 4.75% – here's how. Most light bulbs operate off mains voltage ( see below), but some light fittings are designed to be lower voltage. These are most commonly used in integrated kitchen fittings, where space is at a premium and smaller bulbs are a necessity. Low voltage light fittings often need a compatible transformer ( see below) to convert mains voltage to the correct, lower voltage. Most low voltage spotlights will be between 12-24 volts.

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. The ~ sign indicates alternating current. Also, the minimum load is indicated as 10W. This is important when using LEDs 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.Most people who choose to switch to LED will do so for domestic use. In most common cases, the housing of the individual LED light bulb will contain the relevant driver suitable to power that bulb. This means that the bulb is ready for use and will not require any further consideration over drivers/transformers. Bulbs that contain an LED driver and may therefore be used without the addition of an external transformer include: 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.

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. have additional modules that intentionally alter the load seen by the transformer to better replicate the load characteristics of 12VAC halogens and thus ensure broader (but 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)? There are a number of problems, but it is possible non will affect you, so I will try and list them. 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.You can now get dimmable G4’s in 220VAC & 12VDC. This asks the question… is its best to swap the driver and use 12V LED’s or by-pass the original transformer and use 220V LED’s? 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! 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. GU, which stands for “general use”, refers to the base, or fitting, of the bulb. The number after GU refers to the spacing between the pins. GU10 has 10 mm spacing, while GU5.3 has 5.3 mm spacing.

Yes, the transformer has 4 outputs but the bathroom lights are actually pre-wired into a splitter so i only need to use 1 output on the transformer to the splitter if that makes sense? We can determine by the specs you gave that the transformer is indeed AC Electronic Transformer for LV-Halogen Lamps series to give the necessary resistance for the transformer to work. All wiring in homes is done in parallel, never series.

The DC output of LED drivers has the advantage of practically eliminating voltage drop and reducing radiated RFI.

Which driver do I need for my bulbs?

Personally I'd get rid of the transformer and wire in 240V GU10 bulbs instead. The 12V side of the transformer is high current and the number of times I've seen the transformer partially melted due to a poor (high resistance) connection... also no transformer means one less thing to fail. 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.
