Anyone know the answer to this ?……My lights are 12 volt……20 Watt max…….Halogen…With transformer….. There are 4 lights…… 20w bulb in each one……MR16….GU5.3…. 50mm wide by 45mm depth The sale of higher energy bulbs was phased out in the UK in the last year. The sale of high energy fluorescent lightbulbs will be phased out by the government by September 23, 2023.

Also I presume a reasonably competent (non-qualified) person can do this (taking appropriate precautions of course inc. turning off the mains supply). LED (light-emitting diode) light bulbs are the most technologically advanced and energy-efficient bulbs available. They last many times longer than halogen light bulbs, produce the same amount of light, but use only a fraction of the energy. Most LED light bulbs can be used with existing light fittings (this is called retrofitting). You would need a transformer to reduce the mains voltage down to 12 volts. There are two types of transformers available in the market. One is the electromagnetic transformer and the other is electronic. Electronic transformers are preferred due to their efficiency and low cost. #3 The compatibility

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. At this point, it’s important to note that if it is a halogen transformer,this maximum load applies to halogen light bulbs only. For example, if you have a 40VA transformer for halogen bulbs, you should not install 40-watts worth of LED light bulbs. This would overload the fitting and potentially cause a safety issue. 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). Saving money and the environment are the benefits of replacing halogen with a light emitting device. Is it worth replacing bulbs with LED? 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.

I guess an alternative would be to fit new GU10 lamp holders with LED bulbs and ditch the transformers. Do you think thy is would be a better approach? i’ve tried replacing my warm led spotlights with brighter led spotlights but they flash on and then go super dim. Can you help explain why that might be?

They are brighter and produce a negligible amount of heat as compared to them. Moreover, the average life of a G4 LED capsuleis 30000 hours, which is ten times more than the halogen bulb. They have no toxic chemicals like mercury or Barium, thus posing no threat to human health. For example, if you have one 35W halogen installed in your kitchen, ensure you swap it for 35W equivalent LED. The actual wattage of the LED light bulb may vary, but the equivalent wattage must be the same as your current halogen light bulbs. For example, you might find both 5W and 6W LED light bulbs that have an equivalent wattage of 35W; both of these would be fine to replace 35W halogen light bulbs.” Yes, that’s right. The maximum load that the transformer/driver can handle is what you should be looking for in your MR16 downlights. If you have 35W halogen downlights that are installed with 10 to 60VA transformers, we can replace them with a new set of lights. Can I put LED bulbs in halogen fittings? As most LED bulbs have a much lower wattage, for example 5W – this falls below the minimum rating that the transformer is designed for (20W). The number 4 in the name indicates the center-to-center distance between two pins, which is 4mm in this type.

There are light emitting devices you can use in your fixture. The equivalent of a 50 watt bulb will burn between six and seven watt. Can I replace 2 pin halogen bulb with LED? FAQ about 12V transformer and light emitting device compatibility. The cost of efficiency and extra power consumption are explored in the FAQ article. The ‘LED drivers’ are designed for DC light. What is the difference between halogen and LED? These numbers tell you the maximum wattage that the transformer can carry. For example, a 40VA transformer can handle up to a 40-watt halogen light bulb, while a 10-60VA one can carry between 10 and 60 watts worth of bulbs. Some transformers might just carry one individual light bulb, while others might be able to carry several lower wattage light bulbs in a series.

The G4 Bayonet Light is non dimmable and has a 2.5 watt light bulb. A warm white (3000K) light is very similar to a normal 20W halogen bulb and can be sufficiently bright. Can I replace gu5 3 halogen with LED? I have a 150w 82v mr13 halogen bulb that I would like to replace with an LED but cannot find one anywhere. I am having a very hard time even finding a 150w equivalent LED bulb of any kind. Any help would be greatly appreciated. My question is – I would think I need to leave the low voltage dimmer instead of switching it to an LED dimmer. As far as I know, a standard LED dimmer is not low voltage. Do they even make an LED low voltage dimmer? Do I need it?

Do I need to swap the transformers for Led drivers, do the also act as a transformer?. Do I also need to replace the dimmer switches? 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? It is possible to replace your bulbs one by one. The warm light of halogen bulbs is within reach thanks to the fact that LEDs can handle all colors of white light. What is 20w halogen equivalent to in LED? If you’re replacing low voltage MR16 50W halogens that have low voltage 12V transformer, the first and obvious option is to replace it with something like an MR16LED. The retrofit lamps should work from your transformer. This can cause you to have to replace your transformer. Can I use 12V transformer for LED? You may run into problems with this transformer, as it is designed for use with Halogen light bulbs and therefore has a wattage range of 20W to 60W.

See also What is the LED equivalent of a 250 watt bulb? Can I swap halogen headlight bulbs for LED? Fortunately, upgrading Halogen MR16 light bulbs to LED is usually a painless affair, as most LED light bulbs are now designed to retrofit to existing light fittings. All you have to do to swap your old bulbs out is remove them from the light fixture and fit the new, shiny bulbs in their place. For example, if you have one 35W halogen installed in your kitchen, ensure you swap it for 35W equivalent LED. The actual wattage of the LED light bulb may vary, but the equivalent wattage must be the same as your current halogen bulbs. For example, you might find both 5W and 6W LED light bulbs that have an equivalent wattage of 35W; both of these would be fine to replace 35W halogen bulbs.
