So the solution is to group the output together to create a single supply of 6a which will supply the led strip lights. This power supply can fit a 20ah lithium battery. Sherlotronics make a 6.5A alarm power supply. I don't know if there are other battery brands that anyone can recommend? Which means that for 2.5 hours of load shedding - and all lights running - you would run a discharge of 75%. I wouldn't want to push the battery that hard but 8m of led strip lighting (4 rooms) would only need about 6a. However, Securi-prod make a 20ah lithium battery that can (supposedly) output 20a. I rate the BlueNova batteries very highly but they are expensive. In my view 2m is more than enough to light most rooms. You can also get a RF remote to control the lights. These can be mounted in an 'A13' corner mounting profile which fits nicely along the ceiling in most houses. These use 9w per metre and provide 1000 lumens per metre. I would appreciate criticism/suggestions to improve my idea.Ī couple websites advertise 12v led strip lighting. You can also check against our quick-reference chart below.Thinking of a bit of a hack to provide some lighting during load shedding - using 12v led strip lighting. 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. 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 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. 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.

From a full charge, the battery pack is able to provide about a full hour of continuous illumination of an entire reel.
