About Calculate Method:
If Your LED Strip 60LEDs/m, and each LED 0.2W, then calculate max led Strip Length: 0.2W/LED × 60LEDs/m=12W/m, 24W(this listing)÷12W/m=2m, As a result, Support the LED Strip (60LEDs/m, 0.2W/LED) Length (Max)=2m.
 
Special Note:
This Power Supply Unit "DOES NOT" come with installation instruction, on/off switch, or screws.
Professional Installation of qualified electrician is highly recommended.
