How to choose the right LED for your next project.
When it comes to lighting, the auditing process is the most important and should not be taken lightly (pun intended). Many factors must be considered such as client requirements and needs, lumen output, location, and colour temperature.
Client Requirement and Needs: Every project is different and so are the people and buildings that are dealt with. Things to take note of when initially discussing the options for LED lighting are the goals of the client. Are they going for purely energy efficiency? Maybe they care most about new fixtures and aesthetics? Or in most cases it’s a mixture of both.
Colour temperature is another critical question to think about because it can change the ambiance of a room dramatically. Standard practice is 3000K (yellow/orange) if you want a relaxed feeling, 4000K (white/yellowish) is commonly used for office environments, and 5000K (Bright White/Blue) or higher for shops and warehouses that require extreme accuracy.
Light Output: There are three definitions related to light. They are, Lux, Lumen, and Foot Candles. For simplicity, we will only learn about lumens in this article because it is the most common definition used on packaging. A lumen is simply a measurement of light within a square meter. A brand new T8 fluorecent 4 foot lamp gives off around 2000 lumens. The lumen output of fluorescent drops at a rapid pace compared to its LED equivalent. You can find T8 LED tubes in many lengths and sizes to fit any project. LED T8s also come in various wattages which are proportional to the amount of lumens it produces. For this example, I would go with a 14w LED 4 foot tube that outputs 1800 lumens. Even though the lumen count is sightly less then the fluorecnt T8, the LED will last up to 50,000 hours and the lumen output stays about the same over its life time. One last thing to mention is that LED tubes give off directional light versus omni directional. This means that more light will reach the intended area of use.
