![]() ![]() You can also check against our quick-reference chart below. We recommend reading our guide to connecting an LED strip to a power supply for further detail. Most battery packs will either provide bare wire or DC connectors as its output terminal, the same as most wall plug power supply units. One additional piece of the puzzle is making sure that the wires and connectors are compatible. Exceeding this limit may result in shortened battery life or damage to the battery. We strongly recommend making sure the LED strip does not exceed this limit. Many batteries will also specify a maximum instaneous amperage limit, typically expressed in Amps. The result is the expected battery life in hours. mAh ratings for common battery types are below:įinally, divide the battery mAh value by the LED strip mA value. Then, find the mAh rating from the battery. If is provided in watts (W), divide the number by the voltage (e.g. Using a 20 section of our popular LED Flex Strips, powered by an 8AA battery pack, we created our first battery powered LED strip kit. If it is provided in A (Amps), multiply the number by 1000 to convert to milliamps (mA). It is usually expressed in watts per foot or meter. ![]() This is usually provided in a specification sheet for the LED strip product. This value indicates the number of hours the battery can provide a certain electrical current (mA) or power (W) before it runs out of charge.Ī bit of simple math is needed to calculate how long a fully charged battery can be used to power an LED strip.įirst, determine the power draw of the LED strip in watts. If you want to use standard AA batteries, you can use a battery holder that creates a 12V voltage from 8x 1.5V AA batteries.īattery capacity is typically calculated in milliamp hours, abbreviated mAh, or watt-hours, abbreviated Wh. Unless you have a specific situation that requires something else, 12V should work just fine. The most common LED strip and battery voltage combination is 12V DC. Conversely, under voltage is not usually harmful to the LEDs, but can result in reduced brightness or no illumination at all. The copper solder pads make it so each strip piece is addressable even after being cut. At each cut point there is a black line with copper solder pads that sit on each side. The main thing to be aware of is that a battery providing a voltage level above the LED strip voltage spec can result in damage to the LEDs. Cut-to-size Cutting LED strips is very simple thanks to the cut lines along the strips. The primary requirements for powering an LED strip from a battery are:ġ) LED strip voltage must match battery output voltageĢ) Battery supply capacity should be sufficient for your needsģ) Connectivity method between LED strip and battery pack must match Voltage Selection See below for some general tips and guidelines for finding a compatible pairing. The options for connecting a battery to an LED strip are by no means limited to the method and accessories we tested. Waveform's FilmGrade dimmer connects between the battery pack and LED strip, acting like a "valve" that reduces brightness without any flicker or change in color.Īs expected, battery lifetime improves in direct relation to the dimmer setting. For this, we use a PWM dimmer which fits right into the low voltage DC system. We often find that the brightness of the LED strip can be reduced in certain scenarios. When not being used, we recommend unplugging the LED strip completely as a precaution. To temporarily power off, simply click on the power button on the battery pack. This translates to approximately 1 hour based on the FilmGrade LED strip power spec of 90W per reel. The official battery capacity specification provided by RAVPower indicates 85Wh. It can also be cut to the length you needed by cutting on the copper dotted line. it has a wide variety of uses, some of which include being in closets, cabinets, wardrobes, cupboards etc.From a full charge, the battery pack is able to provide about a full hour of continuous illumination of an entire reel. Equipped with strong adhesive both on the back of remote control and LED strip allow you to quickly mount it wherever you need. it has 30pcs of SMD2835 superb quality LED chips, which have long lifespans, are flicker-free and provide anti-glare light without strobes and radiation. it has a wide induction distance of 3-5 meters and its sensing angle is 120°. When in "Auto" position the strip is controlled by sensitive PIR motion sensor, but in "Manual" it works with the "ON/OFF" button requiring the user to turn it on and off when needed. Do you want to make your closet look more gorgeous? Want to add more lighting without having to pay for excessive wiring? This kind of PIR motion sensor controlled LED light strip will be your ideal choice! it also features an "ON/OFF" button on the top and the "Manual/Auto" switch on the side.
