24V standard voltage sources

Standard voltage sources or transformers For 24V LED strips and other 24v LED lights. Choose about 20-30% higher power supply than the need is if the power of the LED tape is eg. 18W/m 24v and the tape length will be 2M (18W x 2m = 36W), for example 50W 24V standard voltage power supply. The standard voltage source may also be higher than the power of + 20-30% of the LED tape, but not lower.
