You flick on a light bulb, the room lights up. It works! Great.
So how much light is it making?
How do you measure the amount of light coming from the bulb?
It’s called Lumens. Lumens is how much light is coming out.
How much energy does it take to make that amount of light?
That’s called Watts. Power is measured in Watts.
The more Lumens per Watt the better. It saves you a lot of money!
How does the light look?
Does it look a littl blu-ish, or a little yellowish, or pure white?
That’s called the Colour Temperature.
That’s why we chose Natural Soft White 3500K for our bulbs.
How does the light spread?
Does it only point one direction, or does it shine all around?
That’s called the Beam Angle.
Sometimes you want a light to shine all around, and sometimes you want a spotlight or a floodlight that shines mostly in one direction. It depends what you’re lighting.
That’s called Colour Rendering and it’s measured by the Colour Rendering Index (CRI).
So now you know more about light!
Light is key to our very survival, so it’s good to know about it.
