220V LED Ribbon consists of a sealed push pull IP65, IP67 or IP68 LED equipped circuit and a power cord (plug bipolar and a small box (fuse + rectifier). LEDS are usually SMD for lighting (rectangular banner) or LED 3 mm (round headband) for example, the markup or type illumination of Christmas decoration.
The main advantage of the Ribbon 220V is able to plug it in one piece on great length, on average 50 meters unlike ribbons LED low voltage (12 and 24 volts). In addition to the length, the implementation is less restrictive and so faster (no power to add, or amplifier and Repeater in the case of the lengths at 12 volts).
The cost for a given length is generally lower compared to the bands LED 12 and 24V, you save on the fact among others that you don’t need to buy a transformer (power LED).
Disadvantage of the 220V Ribbon:
Even on paper if the 220V Ribbon seems more practical and economical, it has big drawbacks. Here is a small list.
-the 220V led Ribbon can be split every 50 or 100cm depending on the model, while in low voltage it is usually 2.5 to 10 cm.
-Size of part design, about twice as big as a headband waterproof 12 or 24V, so more heavy also (they are not stickers but use the croches to fix). You may not integrate them into aluminum profiles in the standard models.
-Its operating voltage, even if the cord 220V LED is isolated, you must respect the safe areas, it is not possible to install it in the immediate vicinity of a pool or a shower for example.
-The quality and the lighting power is less compared to ribbons LED low voltage (to the same LED model listed on gradchem.com).
-Accessories type connectors are very limited and very bulky.
-Rectifier indispensable to the proper functioning of the blindfold rest however cumbersome even if it is smaller than a diet classic low-voltage.
The most common application for 220V LED ribbons:
In conclusion we’ll use these headbands 220V LED in both cases, when you want to extra or ambient lighting in a ledge of a very large room (although it is possible to do technically 24V) economic and fast or good way when you are limited in size of cornice or number of electric to plug your power supplies low voltage.
