A term used to compare LED light bulbs with their incandescent alternatives. An LED light bulb with an equivalent wattage of 35W is a direct replacement for a 35W incandescent light bulb. This is different from a light bulb’s stated wattage ( see below). The recessed fittings need replacing, and a switch to LED would be sensible at the same time. But I don’t want to replace the transformer. 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? 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). The Halogen bulbs give off a fixed color temperature and consume more power than the LEDs. The lm per watt ratio for LEDs is 80 to 100lm/W, compared to 16 to 24lm/W for halogens. This means that the lights use less energy. Is it worth replacing halogen with LED?

The G4 lamps are types of the bi-pin or two-pin standard, defined by the International Electrotechnical Commission (IEC).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? I have 2 gu4 halogen bulbs in my fireplace. I’ve tried to replace with two led bulbs. When I install the new led bulbs they dont work. If I leave one led bulb in and install 1 halogen bulb in the led light lights up. The halogen bulb does not. The number 4 in the name indicates the center-to-center distance between two pins, which is 4mm in this type.

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? I am currently looking to replace the halogen MR16’s in my daughters room which are currently 12v 50w on individual transformers. Can I change these for 35w equivalent MR16’s or do they need to be 50w equivalents.

I have 6 downlight fittings in my lounge on a single dimmer switch. I want to replace the current lamps for LED version. The info. on the bulb is LCLEXNE MR16+C 12v 50w 1045. 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. It is possible to switch these for LEDs without changing any of the parts. If the bulb has 2 pins that push into the fitting, it’s probably a low voltage MR11 or MR16 bulb. If you want to use these bulbs in place of a halogen bulb, you need to use a transformer. Are halogen bulbs being phased out? Spotlights are ‘directional’ bulbs that emit light in a focused beam. Halogen spotlights are a form of incandescent light bulb that use a tungsten filament and a mix of inert and halogen gases to produce light. The European Commission directive in September 2016 banned the manufacture of this type of power-hungry spotlights. 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.
