this is what I have.Â [I have bought two spare ones]. BASIC POINT: You need to get a professional electrician to install a compatible power supply first. Then you can install a higher power LED. Not something to be attempted by oneself.]
What does this mean?
DL13 – not clear but possibly stands for the wattage?
3000k – stands for the colour (orange)
It is SMD which means “Surface Mounted Devices”, a special type of high power LED light. “An SMD LED is a surface-mount LED that reduces the size of the light while at the same time adding more colors to a single LED”
IP44 – this is an “ingress protection” rating . See this.
Class II indicates that a power supply is double insulated and doesnâ€™t need an earth pin.
A power factor of >0.9 “The power factor rating is the ratio of real power (Watts) used by the load compared to apparent power (Voltage x Current drawn) into the circuit: Power factor = Watts / (Volts x Amps)”
Basically one needs the voltage of the power supply (also called “driver”) to be compatible with the voltage of the actual bulb. LEDs are driven by constant current (350mA, 700mA or 1A) drivers or constant voltage (10V, 12V or 24V) drivers.
This is how the power supply is installed.
