Nevertheless, the term low voltage is generally used to distinguish it from line voltage technology. There is also a range of low voltage LEDs with an operating voltage of 24V. The only advantage over the widely used 12V lamps is a lower power loss with long cable runs between transformer and light source. However, this is not an issue for most home installations. There are many LED lights in line voltage as well as in low voltage version available.
Both emit the same light. When should you choose which variant? In many cases it makes no difference, but in some situations the technologies have advantages and disadvantages. Line voltage LED lights have their own integrated power supply unit and can be operated directly with the mains supply. No extra transformer is needed.
Line voltage LED lights have a higher power dissipation than the low-voltage version due to the integrated power supply unit. This results in higher waste heat, which can be a problem depending on the installation situation. In small lamp glasses or recessed spotlights, heat accumulation reduces the lifespan of the LED. With V mains voltage, all safety regulations must be observed during connection and operation.
A word of caution here though as it can be a little complicated to find the best one for your down light. Not all low energy GU10 bulbs are equal in terms of size or light output and most are considerably longer and often fatter than a halogen GU10, so may not work with your down lights. Not many of the energy saving GU10 bulbs are capable of being dimmed. Low energy GU10 bulbs are available that are the same size as halogen bulbs and will fit into any light fitting that uses GU10 bulbs.
Please take care to select bulbs that will work in your fitting and give you the light output you want. These have a number of advantages over halogen GU10 bulbs. They are cool to the touch, very low energy which gives you huge savings on your electricity costs and are very long lasting over hours. A good quality 3 watt LED GU10 will roughly equate to between 35 to 50 watts of standard light output. Halogen lighting is now being phased out, however the low voltage lighting industry is now dominated by the much more energy-efficient LED technology.
In an ever more pronounced shift away from standard v mains voltage lighting, low voltage lighting and its benefits are winning over consumers everywhere. Initially developed to facilitate safe outdoor landscape lighting, the technology is now also used indoors and works by using an LED driver or transformer to step the voltage down from v to 24v, 12v or lower.
The driver or transformer is either built into the light fitting itself or installed separately, but its presence is essential for the operation of the light. The benefits of low voltage lighting are often debated, but some are undisputed.
Other low voltage bulbs include the MR11, which is a smaller version of the MR The G4 is also low voltage too. The simplest way of differentiating between bulb voltages is by checking their fitting. Mains Voltage Most bulbs that are used for general purpose lighting are mains voltage. Categories: Advice.
