The transformerdriver can be built in to the bulb or it can be located outside.
Led lights with transformer. Therefore while it is better to work with LED drivers for smaller projects transformers would be the best option to regulate current for more intricate LED light systems with many bulbs or chips. Buzzing Dimming or Flickering Lights. Is a transformer required for LED lights.
By nature LEDs run on low voltage dc. 99 of LED strips sold require a constant voltage supply and are usually supplied with basic ACDC transformers but may also be supplied with LED drivers eg. H28mm x W139mm x D45mm.
This is a common problem when LED downlights are used without an LED driver. If the LED lights on the transformer flicker the minimum load is significantly lower. The transformers for RGB LED strips are the main choice because they can produce millions of colours by combining red green and blue the primary colours while the RGBW versions do the same thing adding a white light in cold or warm tones.

They will have a transformer either in the ceiling or light fitting. LED transformers are capable of controlling a greater flow of electrical power.
Then the minimum load would be reached but this mixed operation is not a nice solution. Up To 40000 Hours Life Expectancy. DALI dimmable 1 of LED strips sold operate with constant current and these require an LED driver.
You can integrate the LED transformers into the light fixture or embed them into the plug as long as it connects between the light source and power source. This is because the higher voltage from the halogen transformer can damage the LED and actually result in lower light output. When installing LED or any low voltage lighting fixtures a transformer is used to reduce the voltage from 120 volts to 12 volts.
