DC24V MW Class II Power Adapter

You don't need to measure the circuit, just the lights. To find the power your LED strip needs, multiply its watts-per-foot by the total length in feet. For example, a 16-foot run of strip that uses 5 watts/foot needs 80 watts (16 x 5 = 80). Then, add a 20% safety margin. So for that 80W strip, you'd choose a 96W or larger AC DC adaptor 24V, like our 120W GST120A24 model.

The vast majority of these MeanWell adapters use the industry-standard 2.1mm DC power plug. Specifically, it's a 5.5mm outer diameter and 2.1mm inner pin diameter, which is the most common size for LED strips and controllers. If you have a device with a different sized jack, let our team know and we can find a solution.

A Class 2 LED driver is a power source that's limited to 60V DC and 100VA (or 5A). This limitation is a safety feature required by the National Electrical Code (NEC) in many residential and commercial applications. It means the output is considered safe from both fire and electric shock hazards, often simplifying installation requirements. 

Simple enough: the green LED light just means the adapter is receiving AC power from the wall and is on. If that light isn't on when it's plugged in, check your outlet and the AC power cord connection to the adapter brick itself. It's just a power-on indicator, it doesn't show load or faults.

They absolutely are. The MeanWell GST series is specifically designed as a reliable green industrial power adaptor. They have higher efficiency ratings (Level VI), better build quality, and more comprehensive safety certifications (UL, TUV, CE, etc.) than typical consumer-grade chargers. We've seen these run for years in retail displays, museum exhibits, and office lighting projects.

That depends entirely on the wire gauge and the power draw of your strip. As a general rule, with standard 18 AWG wire, you can go about 15-20 feet before voltage drop might become noticeable. If you need to go further, you either need to use much thicker wire or rethink the layout. 

Yes, you can. As long as it's a quality, UL-listed power strip or extension cord that can handle the adapter's rated power, it's perfectly safe. Just be sure not to daisy-chain multiple extension cords together, and use a cord with a wire gauge appropriate for the distance and load. For permanent installations, plugging directly into a wall receptacle is always the best practice.
