Three ways to help your LED purchases
When I went to purchase my first LED bulb I picked up the box and examined it frantically looking for how many Watts it had. I thought Watts were the be-all and end-all of the lighting world, as did my family and friends. Most of them still do. Surprisingly, and slightly worryingly; it wasn’t until I got a job at an LED company that I realized all these years I’d been thinking about Watts the wrong way.
With the new push for LED bulbs; Watts, Lumens and Kelvins have all been placed on the packaging. All three of these give the consumer the information they need to make an informed buy. This article is about promoting a better understanding of these three measures in order for you to make the best purchases possible.
Watts measure the amount of power your bulb is using. They do not measure the brightness of your bulb. Over recent years due to the use of traditional incandescent bulbs, the amount of Watts your bulb had was related to its brightness. However, now with new energy efficient bulbs such as LED’s it is becoming increasingly difficult to correlate Watts to brightness. This is because two different LED’s may be able to produce the same lumens (brightness) using a different number of watts. Due to this fact it is important to learn what Watts, Lumens and Kelvins really are.
First of all, Lumens is a measurement of total light output. This means that the higher the Lumens, the brighter the light will be and the lower the Lumens, the dimmer the light will be.
Provided below is an estimated conversion chart in order to give you some idea of how many lumens you will be looking for when you’re replacing your bulbs.
Understanding Lumens actually makes buying your new bulbs much easier as they enable you to purchase the exact amount of light you desire.
The next time you have a bright idea to go purchase a SANSI bulb you can consider Lumens and not Watts.
William Kelvin a Scottish physicist discovered that heating a block of carbon at different temperatures made it glow in different colors. To honor his discovery, the color temperature of light is now measured using the Kelvin scale.
After reading this you may be asking yourself what is a color temperature? So I will provide a brief definition. Different light sources emit different colors of light. Candles produce a red colored light while the midday sun will produce white light with a hint of blue. These colors can be measured and shown numerically and this is done through color temperature.
It is important to remember that the color temperature is not actually referring to the temperature of the lamp.
The colors that have a lower color temperature are at the start of the scale in Red and the colors that have a high color temperature are at the end of the scale in Blue. So as the color temperature increases it will move up the scale and change color.
The most complicated aspect of this scale is that lower temperature Red lights are considered warm lighting and higher temperature Blue lights are considered cool lighting. However, the best way to remember this would be to think of the Red warm lighting, as a candle or a fire.
The SANSI smart light can show a full spectrum of color temperature, which makes it ideal for home lighting as it is so flexible.
As a basic guideline for light temperatures cool lighting is preferred for visual tasks and warm lighting is better for living as it is soft and flattering to how objects and people look.
Knowing these color temperatures is very important if you want to buy the optimal bulb for your home, office or building.
Having an understanding of these three specifications will really help your future purchases. So the next time you are shopping for SANSI LED BULBS you can now look at their Watts. Lumens and Kelvins in order to get the exact light you want!
