Are you looking for a round surface mounted waterproof panel light? And, do you know how to choose a right one for your home decoration? Let’s started!

What Is A Panel Light?

Panel lights are also called flat panel lights, snap panel lights. Commonly used places include including kitchens, bathrooms, living rooms, aisles and other home spaces, such as some kitchen and bathroom lights, integrated ceiling lights and so on. Office, shopping malls, etc. will also be often used.

The principle of panel light, LED early usually used as a display backlight, and later gradually developed into a specialized lighting fixtures. The initial panel light is to use the principle of LED backlighting, LED light source in the back, the light through the diffusion plate directly projected down, that is, straight down the panel light.

There is the use of side-emitting light guide principle, that is, the LED light source in the lamps and lanterns around, through the light guide plate, reflective plate to form the effect of front projection. Also known as side-illuminated panel lights.

Panel light common light source LED, fluorescent tubes, etc., now the most commonly used is LED light source. Panel light with LED as the light source has the advantages of long life, high luminous efficiency, low power consumption, low energy consumption, environmental protection.

Due to the unique characteristics of the panel light, so the LED panel light also has a large light surface, does not take up space, light uniformity, simple appearance.

Convenient maintenance and other advantages, suitable for bathroom, kitchen, office and other lighting use.

Is 12w Panel Light Brighter Than 9w Panel Light?

It is generally believed that more number of watts means more brightness. However, the fact is that wattage has nothing to do with brightness. Wattage is the amount of electricity consumed by a light source. You should check the lumens as that is a unit of brightness.

What Is Lumens?

Lumens are a measure of brightness emitted by a particular light source. In simple terms, the intensity or the brightness of your light is called lumens. Most people tend to mix lumens with consumption. However, watts are related to consumption of electricity whereas lumens are all about brightness.

Lumens equal brightness

Lumen is a measure of brightness produced by a particular light source. More lumens per watt equals to more brightness.

Switching to LED lights will give you:

Brightest light output

Reduced electricity bill by almost 60-70%

An LED bulb is much safer as it does not emit toxic mercury unlike a CFL bulb. (When toxic mercury comes in contact with human body, it can lead to various health hazards that could prove fatal especially for kids and pregnant women)

How to Convert Lumens to Watts

Step 1: Understand Watts

Watts are a measure of energy consumption. When we pay our electric bill, we pay for the number of watts we use. A 60-watt bulb consumes 60 watts of energy. Since we used 60-watt incandescent bulbs for so many years, we associated a certain level of brightness with 60 watts. But we can’t do that anymore, since LED technology produces more light while using fewer watts. Instead, we need to use lumens.

Step 2: Understand Lumens

A lumen is a measure of visible light energy. The higher the lumens, the brighter the light. All lighting manufacturers are starting to tell us how many lumens are produced by each of their products. We see these lumen numbers on the Lighting Facts labels found on all new LED bulb packages. It may take a while to get used to using lumens instead of watts, but it’s important in order to make the best lighting choices.

Step 3: Understand Efficacy (Lumens/Watt)

Now that we understand watts and lumens, we can use both terms to come up with lumens per watt or “efficacy” (or “luminous efficacy”). This is a measure of how well a light source converts energy (watts) into light (lumens). The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt. Depending on the bulb and the manufacturer, LED technology typically produces 75-110 lumens/watt. So, LEDs are generally about 7 times more efficient at producing light than incandescent bulbs. Use a 7:1 ratio as a rough guide when selecting an LED bulb to replace an incandescent bulb.

For example, if you wanted to replace a 60-watt incandescent bulb, what wattage LED bulb would be roughly equivalent? Using the 7:1 ratio, simply divide 60 watts by 7 to get roughly 9 watts. But efficacy varies greatly from manufacturer to manufacturer, so it’s best to check the Lighting Facts label and try to match lumens. Also, a label will sometimes (but not always) tell you that an LED bulb has an equivalent brightness. Refer to the charts below for a ready reference.
