How are LED lights calculated?
To calculate an LED's power use, simply multiply the LED's voltage (in volts) by the LED's current (in amperes). The result, measured in watts, is the amount of power your LEDs use. For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power.
How many can lights for a 12x12 room?
How Many Can Lights For A 12×12 Room? The typical rule-of-thumb is 24″ from each wall, and then 3-5 feet between cans. So in a 12′ room you'd probably want two rows of lights. Considering it is a bedroom and you don't need it as bright as a kitchen, you can probably get away with 2 rows of 4 lights for a total of 8.
What LED wattage for bedroom?
The best light bulbs for your bedroom are 12 watts LED bulbs with a brightness of at least 800 lumens and a Kelvin range of 2200k – 3000k.
How do you calculate LED strip wattage?
Take the length of your LED strip in feet and multiply it by the watts consumed per foot, then multiply by 1.2. This will give you the minimum sized power supply you'll need to run your strips.
How far can you run LED strip lights?
24V DC LED strip longest length is 32ft (10 metres). 24V Constant Current (CC) LED Strip is 65ft (20 meters). 120V LED Strip maximum length is 164ft (50 meters). 24V RGB & RGBW maximum run lengths are 23ft (7 metres).
How many feet of LED strips can you connect together?
This is no different with LED strips. Vetco recommends, as a general rule, not to connect more than three complete strips end-to-end without adding in extra, higher gauge power wire or additional power supply units down the line.
How many lights do I need in a room?
This will depend on the individual room and what it's used for. As a handy rule of thumb, a sitting room or bedroom will generally require around 10-20 lumens per square foot, while a bathroom or kitchen will need a stronger level of lighting, at around 70-80 lumens per square foot.
How do you calculate the wattage of a room?
Wattage: Multiply the area in feet by 10. For a room 20 feet by 20 feet, we obtain 400 sq. ft., multiplied by 10 to give 4000 watts. The number of watts = area x 10.
How many watts is a 5m LED strip?
