What the BULB?

Are you in the dark about light bulbs? We’ll decode the words you need to know when buying light bulbs.


Lumens are a measure of the total amount of visible light the human eye can see, from a lamp or light source. If the lumen rating is higher, it means the light source/lamp is brighter. 


Color temperature is a way to describe how the light appears from the source. It’s measured in degrees of Kelvin and is on a scale from 1000 to 10000. In most homes and commercial spaces, the lighting application of Kelvin temperatures fall somewhere between 2000K to 6500K

Color Temperatures

Warm White is around 2000K to 3000K on the Kelvin scale

Cool White sits at around 3100K to 4500K on the Kelvin scale.

Daylight is from 4600K to 6500K on the Kelvin scale.

Types of Light Bulbs


LED or “Light-emitting diode,” is a lighting technology that is way more long-lasting and is super energy-efficient however they are not quite universal yet. They can’t replace other bulbs yet. LED lights only provide directional light and not diffused light. They’re not ideal for general room lighting. Newer models are clustered together to address the issue.


Incadescent light bulbs are the most commonly used light bulb because they are the cheapest option available. It usually gives off a warm light temperature. It’s complimentary to skin tones and are more pleasant according to psychology. They are not the most energy-efficient option though, they only usually last between 700 to 1000 hours. They are great dimmers though!


Halogen bulbs are a variation of incandescent. They give off light that’s the closest to natural daylight or “white light.” Colors are said to appear sharper under this light and they’re also great dimmers. A little bit more energy-efficient than it’s predecessor, but definitely more expensive and burns at a higher temperature. These are usually used in pendant lights, or hidden lights because you cannot touch this with your bare hands. The smallest residue of oil from a human hand can cause the bulb to explode because it will make the bulb warm too quickly.


Compact fluorescent bulbs or CFLs consume a quarter of the energy that incandescent bulbs do and last approximately ten times longer. Unlike it’s predecessor, CFLs are quiet, they turn on instantly and have color-corrected tones. It’s very versatile and can be used anywhere you can use the incandescent bulb. They contain a little bit of mercury so do your best to prevent breakage. And remember to recycle this when this burns out.
