If you are a first-time LED buyer, or just simply re-assessing what kind of lights you want in your building, there are a lot of factors that you’ll need to consider.
First, it is important to understand how the lights will be positioned in your building and what function the space will serve. There’s a big difference between needing to light a conference room and a utility closet.
LED bulbs can range anywhere from $10 to $20. There are a number of considerations you can make to determine your budget — including the overall value of a particular bulb in your building.
Will you spend more than you did on older bulbs? Yes. LEDs are more expensive, it’s true, but the long-term savings can help you over a span of time. You’ll also need to replace it fewer times, saving potential labor costs.
Lumens and watts
A light bulb that has a high amount of lumens will make the room appear bright; as lumens decrease, the room will appear dimmer.
Check your current bulb’s specifications to find out how many lumens it produces; then, get the same number or adjust as desired.
Depending on your desired lumens level, you’ll need a certain amount of watts to power the bulb. Look for the lumens level first, and then make notes of the wattage needed to produce that level of brightness.
Note: If you’re switching from an older bulb to a LED, the bulb will require far fewer watts than your previous bulb.
Color temperature and CRI
A bulb with higher color rendering index (CRI) will allow occupants to see a greater variety of colors. This can be incredibly important for creating an atmosphere that is comfortable for workers or residents.
The setting will also help determine the desired color temperature. Lights with higher color temperatures will more resemble natural daylight.
Office spaces typically feature lights with mid-range color temperatures (3100K-4600K); the lights will mostly appear white but will still have a lower temperature than than natural light.
Bulbs with lower color temperature (3,000K or less) will have a red or yellow appearance.
