LED Ultra Slim Mini Power Supply

To find the right size for a power supply for led lights, calculate the total wattage of your LED strips (wattage per foot times total length). Then, add a 20% buffer. So if your lights use 80 watts, you'd do 80W * 1.2 = 96W. You should choose the next size up, like a 100W driver. This buffer is crucial—it keeps the power supply from running at 100% capacity, which makes it run cooler and last much, much longer. 

It's normal for them to get warm, but "really hot" to the touch could be a sign of a problem. Most of these drivers are designed to operate up to a certain case temperature, often around 80-90°C (176-194°F). The most common causes for overheating are overloading—running it too close to its max wattage—or poor ventilation. Make sure it has some breathing room and isn't smothered in insulation. If it's correctly sized and still too hot, it could be faulty.

The best way to connect multiple LED strips to one power source is to wire them in parallel, not in series. This means running separate wires from the power supply's output terminals to each individual strip. Don't just connect the strips end-to-end-to-end in one long chain, because you'll get significant voltage drop and the last strip will be very dim. Our guide shows a few ways to wire single color strips correctly.

This depends entirely on the power supply's electrical rating and your local building codes. For an in-wall installation, you typically need a Class 2, UL-Listed driver that is rated for in-wall use and often housed in a junction box. Many of our slim drivers are designed for concealment in cabinets or channels, but not necessarily for burial in insulation inside a wall. Always check the product's spec sheet and consult a qualified electrician to ensure a safe, code-compliant installation.

A constant voltage DC LED power supply provides a steady, unchanging DC output like 12V or 24V, regardless of how much current the LEDs are drawing (up to its maximum rating). LED strips are designed to run on this kind of power. Using the wrong type, like a constant current driver meant for a single high-power LED, would send too much voltage to the strips and burn them out almost instantly. All the models here are constant voltage, which is what you need.

Some are, but most are not. You have to check the IP rating. An IP20 rating means it's for dry, indoor locations only. If you need a power supply for outdoor or wet locations like a bathroom, you need one with an IP67 or IP68 rating, which means it's sealed against dust and water. We have specific waterproof 12V power supplies and waterproof 24V power supplies built for that. Never use an indoor-rated power supply outside; moisture will cause it to fail quickly and create a safety hazard.

Yes, absolutely. A huge part of our business is building power solutions to a customer's drawing. If you need a specific DC barrel plug, a JST connector, or exact lead wire lengths to make your cabinet or display wiring plug-and-play, we can do that. Just send us a sketch or a description of what you need. One of our engineers will spec out the parts and send back a wiring diagram and quote, usually within 12 hours. There's no fee for this service and no obligation to order.

If you overload your led strip power supply, one of two things will happen. A well-designed power supply will go into a protection mode—it will either shut down completely, or it will "hiccup," turning on and off repeatedly. This protects it from damage. A cheaper, poorly designed one might just overheat and burn out permanently. This is why following the 80% rule (using only 80% of the driver's max wattage) is so important. It prevents overload and dramatically increases the lifespan of your equipment.
