Strictly speaking though, there is no such thing as a mains voltage LED – as all LEDs work on low voltage DC (direct current). An LED bulb that is designed to replace a regular mains voltage bulb would therefore require a ‘driver’ to change the electricity supply.
Can you use LED bulbs in low voltage lighting?
While LED bulbs are available to retro fit most low voltage fixtures, the real value in LED comes with the installation of the system. If you have ever looked into replacing light bulbs inside your home with LED bulbs you’ll find it’s more expensive they are and difficult to justify the cost.
Do I need a special transformer for LED lights?
All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally.
Do LED bulbs need special sockets?
Screw-in LEDs require no retrofitting into existing sockets because they contain not just the light-emitting diode but also the electronic driver that makes it work. (In a special LED fixture, by contrast, the driver is in the light fixture and the bulb contains only the diode.)
Are all LED bulbs 12V?
Some LED bulbs work with 230 volt mains AC (Alternating Current) electricity, for example the GU10 LED bulbs. Others, like the MR16 LED bulbs, run on 12 volt DC (Direct Current). All LED bulbs require a ‘driver’ (a special type of transformer) to work properly. … MR16 and other 12V bulbs use an external driver.
Can I replace 12v halogen with LED?
Yes, in many cases, you can simply replace your bulbs separately, one by one. Furthermore, LEDs can handle all hues of white light, so the warm yellowish light of halogen bulbs is perfectly within reach! …
Can I put LED bulbs in halogen fittings?
ANSWER: Yes, there are LED bulbs you can use in your fixtures. The LED equivalent to the 50-watt halogen bulb will probably burn only about six or seven watts. These LED bulbs cost more, $30 to $35, but because they will last for years, they are worth the price. And LEDs give off relatively no heat at all.
Can I use 12V AC instead of 12V DC?
As long as the voltage of the “DC Appliance” is not less than the 12 Volt adapter then it will either work or won’t, all in all it’s a bad idea to experiment, actually it’s a bad idea just to even think about doing it, unless you know about what you are about to do, don’t.
Can I use 12V transformer for LED?
FAQ – 12V Transformers and LED Compatibility. Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article.
Is an LED driver a transformer?
AC LED drivers are actually no-minimum load transformers, meaning they could technically operate low-voltage halogen or incandescent bulbs as well. LEDs, however, cannot operate with conventional transformers because conventional transformers were not made to detect the low wattage of LEDs.
Can I replace a 40W bulb with a 60W LED?
Yes, assuming you’re suggesting an LED that has lumen output similar to a 60 watt lamp. You can use any lamp that consumes up to 40 watts and is shaped similar to the lamp recommended. So for example, if it was a standard A lamp, you could use any LED lamp that consumes up to 40 watts with no safety issue.
Can I use LED bulbs in old fixtures?
When it comes to replacing old incandescent bulbs with LEDs, a common question that customers ask is: “Can I use an LED bulb that has a higher wattage equivalent than my fixture allows?” The simple answer is yes, as long as the LED bulb uses less wattage than your fixture.
Can LED lights cause a fire?
LED lights do not emit light from a vacuum as most other bulb types do. … Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly lower temperature than other bulbs.
Do 12 volt LED lights get hot?
LED lights are designed for a specific voltage, such as 12 volts or 24 volts. … When LEDs are run at a higher voltage they become very hot. The heat can damage the LEDs, or the soldering around them, so they either start flickering, go dim or die entirely.
Are 12 volt LED lights AC or DC?
LEDs are usually considered to be DC devices, operating from a few volts of direct current.
What voltage do LED bulbs use?
Typically, the forward voltage of an LED is between 1.8 and 3.3 volts. It varies by the color of the LED. A red LED typically drops around 1.7 to 2.0 volts, but since both voltage drop and light frequency increase with band gap, a blue LED may drop around 3 to 3.3 volts.
