UL Listing and UL Recognized Designations
UL is a global independent safety science company with more than 120 years of expertise innovating safety solutions. The company advises, audits, certifies, educates, inspects, tests, validates and verifies to maintain safety standards and compliance in manufacturing. When UL has tested
representative samples of a product and determined that it meets UL’s published, nationally-recognized Standards of Safety requirements, the product is given a UL Listed designation. The designation UL pertains to the United States, and cUL is the Canadian designation.
While a UL listing designates that a product has been tested by UL, meets nationally recognized safety standards, and has been found free from reasonably foreseeable risk of fire, electric shock and related hazards, another similar-looking designation means something slightly different. UL
Recognized Component Marks verify that a product has been tested, but that it is a part or component of a larger product. Components can be used to complete or add to end products and systems, but additional installation precautions may be necessary to ensure safe use. It is important to understand how UL Recognized items work to implement the items safely.
Class 1 and Class 2: Why They Matter?
When an LED driver is listed as UL Class 2, it complies with UL standard UL1310 indicating that energy output of the device is safe to touch with no major safety protection required. A UL Class 2 listed item will not carry a risk of fire or electric shock at the LED and luminaire level, operating below 60 volts in dry applications, 30 volts in wet applications, 5 amps, and 100 watts.
This safe output restricts the number of LEDs the Class 2 driver can run, but will be safe for use without additional safety measures in place.
UL Class 1 drivers, on the other hand, possess output ranges that exceed UL Class 2 guidelines. Class 1 drivers have high-voltage output which requires safety protection within the LED lighting fixture. Class 1 drivers can run a higher number of LEDs than a Class 2 driver, making it more efficient in terms of energy output, but as such requires putting additional safety measures in place.
- Yes with LED World’s Dimming Controllers, 12VDC Class 2 dimmable transformers and 24VDC Class 2 dimmable transformers.
- Our Multi-Dim series Dimmable drivers are compatible with Forward phase, Magnetic low voltage and triac Dimmers
- RGB LED Flex Strips can be rejoined by two methods. One, by Soldering (experienced personal) wires to the marked solder points or by using the our Quick Snap connectors.
- These connectors ONLY work with LED WORLD’s LED RGB Flex Strip models
supply with a voltage meter to make sure the correct voltage.
- Disconnect RGB(W) LED Strip from LED color controller. The RGB(W) strip will be directly powered by the class 2 driver to see if there are issues with RGB(W) LED Strip
- Use the respective 12VDC or 24VDC class 2 regulated driver according to 12VDC or 24VDC strip.Connect positive(+) wire to black(+) polarity wire on the RGB(W) LED Strip. See diagram 1. Connect negative(V-) wire to green wire on the RGB(W) LED Strip. RGB(W) LED Strip
will turn green. See diagram 2.
Diagram 1
Diagram 2 - Repeat this process for all colors connecting respective wire colors. If all colors light(pass test) then there is an issue with RGB color controller.
Diagram 3
Diagram 4 - Warning: Please make sure to trace back the wire directly to the RGB(W) LED Strip connection pads to confirm that connection pads connected to respective wires
- LED Flex Strip can be cut at marked intervals by qualified electricians. Typically, for 12v the mark is every 3 LEDS and for 24vdc the mark is every 6 LEDS. Please refer to the enclosed instructions before proceeding. For use with Class 2 Power supplies.
- LED Flex Strip can be rejoined by two methods. One, by soldering wires to the marked solder points or by using the our Quick Connect connectors. These connectors ONLY work with LED WORLD’s LIGHTING 12VDC and 24VDCLED Flex Strip models. Refer the enclosed instructions before proceeding as there is more important safety details. Note! Quick connectors cannot be used with Doublebright or Flex Strip models that have a coating.
