LED Transformer

LED transformer - Most common household LED light bulbs run on 230 volts, but many smaller LED light sources such as the popular LED strips require 12 volts direct current. Here you need to "transform" 230 Volt alternating current into 12 Volt direct current, and for this you need a special LED transformer. You will find a large selection of transformers below. You can also read on at the bottom of the page for some tips on how to choose the best LED transformer for your application.

Do not use an "ordinary" 12 Volt transformer

It's not many years since 12 Volt halogen bulbs were widely used, so most people probably have one or more 12 Volt transformers lying on the shelf. However, these transformers deliver 12 Volt alternating current, and are therefore not suitable for LED, which requires direct current. For example, if you connect a LED strip to such an AC transformer, the LED strip will flash, and probably burn out after a short time.

Instead, you need a special LED transformer, also called a LED power supply. It is designed for the purpose, and will give you constant light in the LED strip and a long life. Remember to choose a model that can supply enough Watt for your installation. It doesn't matter if it is oversized, as the actual power consumption is largely determined only by the connected LED lamps.

Consider LED the location of the transformer

The cheapest LED transformers are often designed as "open" air-cooled types, where you can see the electronics through holes and cracks. It goes without saying that they cannot withstand water, and this type is therefore best suited for indoor placement. Remember also that it must be placed out of reach of little fingers.

A slightly safer option is the splash-proof IP45 versions, which in principle can withstand a minimum of water jetting. However, for outdoor locations or in damp places, the safe choice is the fully enclosed IP65 or IP67 types, which can be described as truly waterproof.
