About this deal

Halogen lamps, like traditional incandescent lamps, use a tungsten filament, but they’re also filled with a small amount of halogen gas (such as iodine or bromine) in a capsule. Keep reading to learn more. How Do Halogens Work?

If that pulsing or otherwise varying "12 volt" supply is used to feed a constant currrent driver feeding a controlled current into the LED element of a lamp there is the risk that the pulsed supply will cause the current driver to operate in an unstable manner and hence be unable to properly control the current it is supplying through the LED. The LED bulb is one or more LED's with some sort of current limiting device called a driver, this is built into the bulb, not normally a stand alone unit, you can get stand alone drivers often rated around 320 mA with a voltage which varies from often 12 to 50 volt, point is a driver controls current not voltage, in the main a bulb has the driver built in, and needs a fixed voltage often 12 volt or 230 volt. The problem is as the user we have no idea what type of driver is inside the bulb. Halogen capsules are used in applications such as caravan lighting, boat lighting, pelmet lighting, or desk lighting. They come in low-voltage G4 or GY6.35 types, or a mains-voltage G9 format. The suffixed numbers in their names are based on the distance in millimetres between their two pin centres.Aurora Ice 5W GU10 - Available in dimmable and non dimmable, it has a nice wide beam angle of 60 degrees

The power supply to LED bulbs can be one of a few devices, the old wire wound transformer will likely power LED lights for years with no problem, if designed for AC, many LED bulbs are marked 50/60 Hz, the switch mode power supply is likely not 50 Hz so no idea what the long term effect would be, however one designed for an output of 0 - 105 VA will likely work OK, however one designed for 35 - 105 with a LED below 35 watt will likely shut itself down. The DC power supply is not the answer either, although you can get DC bulbs rated 10 - 36 volt, in the main the bulbs are designed for AC, likely they will work with DC but in real terms it's just a guess. Unlike mains-voltage halogens, all low voltage halogen lamps require a 12V transformer, which is used to step down mains-voltage to individual or multiple low voltage bulbs, depending on maximum load. Linear Halogens

One advantage of low-voltage spotlights is their sharper, brighter quality of light over their mains-voltage counterparts. In addition to display lighting, low voltage halogen spotlights are common in downlights and wire lighting systems. It is high frequency changes in the supply voltage that make the LED current drivers operate in an unstable manner. High-powered specialist halogen capsules are also available for applications such as theatre, TV, film, or projector lighting. Uses at a Glance Bulb Style This is a low voltage MR16 GU5.3 50W halogen light bulb offering a warm white light (3000K) and having a 2500h lamp life.

Hz AC from a wound transformer ( not an SMPS ) has a sine wave without sudden / instant / high frequency changes of voltage and AC/DC LED current drivers can operate on this smoothly varying supply without becoming unstable. This is easy and now straightforward to do because LED GU10 lamps can be swapped straight over without any wiring or transformers to consider. Here are some options for you to consider if you're replacing your 50W halogen GU10s: With the ban on halogen now firmly in place from 2016, there are still lots of halogen and incandescent lamps out there wasting energy and draining the earths resources. These energy hungry relics from a distant past need to get upgraded to LED. LED is 90% more efficient and lasts for 10 times longer. There are a 3 main options of upgrading from halogen to LED, choosing the right option for you depends on the type of downlights and halogen lamps you've currently got.Halogen is one of the primary technologies used in spotlighting, partly due to the fantastic choice of products available. Another reason for its popularity is its superb colour rendering. A halogen bulb includes all colours of the visible spectrum in its light, which means colour is displayed with more consistency than is possible in LED or fluorescent technologies.
