1. What Is A 18w LED Tube Light?

18w LED Tube lights are LED-based efficient lighting solutions. Here 18w means the light provides top performance when it gets 18w of power.

LED tube 18w has a big LED circuit that contains small LED light sources. They produce light when electricity passes through the circuit.

They do not produce light depending on any gas vacuum or toxic mercury vacuum. As a result, less electricity is wasted in the process and more light is produced.

Other than a big circuit, 18w LED tube lights consist of

• LED Driver.
• Heat sink
• A durable PC cover.

2. What Can Be The Size Of A 18 watt LED Tube Light?

It actually depends on the manufacturer and the market.

For example, a VST 18w LED tube is 4 long. But they can compete with 36/40w fluorescent tube lights because of their efficiency.

However, there are some manufacturers who make customs. 3ft or 5 ft 18w LED tube lights. So, the size of an 18 watt LED tube light is not fixed. But it is around 3-5ft.

3. What Are The Advantages And Disadvantages Of A 18w LED Tube?

The advantages of LED tubes 18w deserve its own article. But here are some remarkable advantages that you must know.

No electric product is completely perfect. So, 18 watt LED tube lights have some Cons too. They are

Cons

• The LED drivers are heat-sensitive. So, you can not use 18w LED tubes in extremely hot temperatures.
• 18 watt LED tubes might emit blue light. Blue lights can cause harm to our eyes. So, it’s suggested not to look at them directly.
• T8 LED tubes 18w are more expensive than its competitors.
• Low-quality 18 watt LED tubes degrade color with long-time usage.

4. What Can Be The Diameter Of  LED Tubes 18w?

The most common diameter for an 18 LED tube light is T8.

However, an 18w LED tube can be of T5, T12, T10, or even T6. The diameter actually depends on the manufacturer and the market.

Here, T is 0.125 inch. So,

• T8= (0.125*8)=1 inch.
• T5= 5*0.125= 0.625 inches.
• T12 =12*0.125= 1.5 inches.
• T10=10*0.125=1.25 inches
• T6=6*0.125=0.75 inches.

Moreover, some manufactures take custom orders of 18 watt LED tube lights. As a result, you have the option to choose any diameter you want from them.

5. Where Can I Use A 18 Watt LED Tube Light?

So, a 180 sq ft. bedroom the lighting need is (180*10)= 1800 lumens.

For, other living spaces it’s around(180*20-30)= 3200-5400 lumens

So, let’s assume we need 4000 lumens for a mid-sized room

But a  T8 LED tube 18w can provide 2000-4500 lumens.

So, we can say a LED tube 18w can provide enough light for most mid-sized rooms.
