How Many LED Panel Lights Do I Need?

What is enough light? The question is difficult enough, but when faced with calculating how much LED lighting you need for a well-lit space, it can become even more complicated.

You may wonder how many LED Lumens of light you need to illuminate your space correctly. It depends on the size and type ( residential vs. commercial ). Still, there’s one way that will always help with any installation: measure from top-down until reaching floor level, then add 2 feet for every rafter or beam to determine an accurate estimate!


The measurement of light emitted by a source, whether it’sit’s led panel lights or Incandescent. This is also known as “brightness” and can be measured in lumens depending on what type you have being used at your reference point: A standard 100-watt incandescent bulb produces about 1 500 – 1700.

The output should still sound intelligent, but now there’s no need for precision numbers since everyone understands precisely how bright their particular technology product does justice!


Lumens measure how much electricity or energy it takes for an incandescent bulb to reach its claimed brightness. Each type of lighting source–LED, fluorescent lamp– has different lumen per watt ratios that determine the amount of light you will get out in your space depending on what’s needed by that particular situation (you can also use watts). To find our optimal setting, well, we’ll need lumens measurements, so keep reading below!

Wattage Equivalence

Watts and lumens are both measuring tools that can be used to determine the brightness of a light source. For example, 100-watt incandescent bulbs produce 1500 max lumen while 10 watt LEDs yield exactly what they say on paper – only 700 fewer magnitude than their counterparts with higher ratings!

This chart shows how many lumens are in each watt of light output. It’sIt’s important to note that not all LED products will have the same lumen-per-watt ratios, which can range from mildly different across ledmyplace lighting applications such as linear led suspension or recessed lamps with trimless bases but may also vary significantly based on specific features like color temperature (4000K vs. 5000 kelvin).

The efficiency of a bulb is measured by the amount it produces for each watt that that’s consumed. Bulbs with higher numbers will use less energy and be more environmentally friendly than those with lower lumens-to-watt ratios, like traditional lighting products rated only “UPF” or U scale Efficiency.

The Breakdown: How Much Light is Enough Light?

Determine Room Square Footage

To find out the square footage of your room, multiply its length times width. For example, if you have a 10’10’ wide and long football field-sized space that is 100 feet in total length from end to end, then Multiply (Multiplication Symbol) both measurements together = 1 hundred thousand sq ft!

Determine the Foot Candles by Room Type or Room Purpose

The foot-candle is a measure of light intensity and how bright it would be if one stood in front of an object with no obstructions. Lighting requirements vary depending upon the type of room being lit: for instance, bathrooms require more than living rooms because they are smaller spaces that need greater illumination levels to ensure visibility without cakes shadows from objects blocking out direct sunlight entering through windowsills above. Doorways etcetera!

Determine the Needed Lumens

Lumens are a measurement of light. To determine the needed lumens for your space, you will need to multiply square footage with an estimate on foot-candles required in that area–for example, 100 sq ft living room needs 10-20 FCF (foot candle) while dining areas require 30+4k lumen per square feet!
