To decide how much power your LED strip driver needs, multiply the length of LED tape you have (in metres) by the wattage per metre. For example… This means you will need an LED transformer that can supply 35 watts (at least).
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.
What type of transformer is used for LED lights?
The LED transformer, also known as stabilised transformer, is perfectly suited to LED lighting. The absence of a minimal load and the low energy consumption are among the benefits of a LED transformer. The coiled transformer (also known as ferro-magnetic transformer) can also be used for LED lighting.
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.
Can I use a halogen transformer for LED lights?
Lower Light Output: It sounds counterintuitive, but the higher voltage from a halogen transformer can actually damage the LED and lead to lower light output. … Buzzing, Dimming, or Flickering Lights: This is a common problem when LED downlights are used without an LED driver. LEDs run on DC power, not AC.
What is the difference between a LED driver and a transformer?
What’s difference between LED driver and LED transformer? A transformer is by convention a double wound device, just ac in, ac out. Drivers are more sophisticated than that and usually give a dc output using a switched-mode system, also they have current regulating and monitoring circuits in them.
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! …
Do LED bulbs run on AC or DC?
A standard LED device is typically powered by a DC supply, and in its simplest form the driver circuit includes a resistor to ensure the correct voltage drop across the emitter (Figure 1a).
Do 12V LEDs need drivers?
Because LEDs require a constant DC of 12v or 24v, LED drivers are required in all LED systems (except those which are specifically developed to be controlled by mains voltage power supplies such as mains voltage tape or LED bulbs).
Do LED lights need a driver?
Every LED light source requires a driver. … Some LEDs already include an integrated driver within the bulb. LEDs designed for household use (bulbs with E26 / E27 or GU24 / GU10 bases and that run on 120V) typically already include a driver. However, low voltage LED light sources, such as some MR- bulbs (MR GU5.

Can I replace 12v G4 halogen with LED?
#3 The compatibility
While replacing 12v halogen lights with G4 LED 12v, it is important to check the compatibility of the G4 LED lights with the lighting fixtures. As mentioned before, most of the G4 LEDs operate on DC voltage, so they will need a different power supply or transformer to operate.
Does each downlight need a transformer?
IC Rated modular downlights do not require a transformer/driver as they are connected directly to a power supply. Therefore replacing halogen downlights with IC Rated modular downlights will save additional energy that would otherwise be consumed in the transformer/driver (i.e. between 1 and 15 watts each).
How much does it cost to replace halogen downlights with LED lights?
Some electricians may charge as much as $100 per downlight, but expect to be charged around $60 – $75 per point for installing LED downlights.
How do you convert a halogen bulb to LED?

- Step 8: Connect the LED Ballast.
Why do my LED downlights keep blowing?
This is because the circuit is not completed as tightly as it could be and the electricity may have cause to “arc” or jump across the contact, rather than simply flowing through it. When this happens it produces more heat in the fitting that is expected or catered for by the bulb, and the bulb can blow.
