Why 24V led strip lights, but 12V led strip lights?
Always many peoples ask me: what is different 12V led strip lights and 24v led strip lights? And some people think that 12v led strip light is used for 12V power source and 24v led strip lights is used for 24v power source.
In fact, it is not correct.
General there are 3 reasons for the difference between 12V led strip lights and 24V led strip lights:
1, Different power source
2, Safety regulations
3, Usage
The point ‘1’ is very clear. I just explain point ‘2’ and point ‘3’
Regarding Safety regulations
as we know, the safe voltage is ‘36V’ in electronic area. Because we almost have no feeling when we touch below 36V. So, always every safety certifications limit the power output voltage can not over 36V in anytime. So 12V power source is more popular than 24V power source. Because 12V is more easy to meet the require of rules than 24V. Maybe you will say 24V is also lower than 36V. Yes, you are right. But please note that the word ‘anytime’. General, power source have a rush current and voltage at turn on the power. So the rest voltage is very important.
As to the usage.
Now, most of people known that 12V led strip just can run 5Meter Max. before there a huge voltage dropping and brightness dropping. It is the problem. But If we use 24V led strip lights, we can run 10M Max. it is the different.
Another side, 12V led strip lights can be cut every 3leds, but 24V led strip lights just can be cut every 6leds. It is another different.
Both different is because the different design in circuit.
In the end, let us review the design circuit 12V led strip lights and 24V led strip lights
