– NOT ALL LED FIXTURES ARE THE SAME –
How to compare LED fixtures to ensure the most efficiency for your investment.
When comparing LED fixtures there is a lot of confusion around how to make an educated comparison. Some LED fixture providers create this confusion because they don’t want their customers to figure out that their technology is already outdated/obsolete. The most important factor to take into consideration is LUMENS-PER-WATT! (FYI, all of our fixtures are industry leading)
Read through the following tips below to ensure you get the most out of your LED upgrade investment.
Total watts per fixture is only one of the factors that determines efficiency. In order to see how efficient a lighting fixture is you also need to know total lumen output that makes it to the desired area you want to light. The important thing to remember is that total lumens is different than total lumens reaching the desired area you want to light. This is where beam angle, direction, and light diffusion come into play.
Sound difficult? View the illustration below to get a better feel for what we are talking about.
HID with Glass Diffusion Hood
A typical warehouse fixture using a Metal Halide or similar bulb normally has a lot of spill because of how the bulb is shaped. This means that you waste significant energy lighting up areas of your warehouse like ceilings and walls. These bulbs also quickly become less efficient and change color temperature as they age.
Single LED with Metal Hood
Single LED fixtures (outdated technology) can produce hot-spots with diminished fall off light. These hot-spots mimic a flash light effect which makes it difficult on your eyes adjusting to the varying brightness. You can also waste a lot of energy if the beam angle is not properly sized to the application.
UFO LED Fixture with Direct LED’s
A LED fixture that is properly sized and designed for the application. Each LED uses its own beam angle modifier to produce consistent and even lighting so that optimum lumens reach the desired location to be lit. Minimal spillage and ultra efficiency are achieved.
Color temperature also plays a role in lighting efficiency. Different color temperatures (Kelvin) change how someone sees the light. Toward the edges of the spectrum (orange or blue) a person will typically require more lumens to perceive the same amount of light compared to a true white light. Color temperature also has an important part in impacting the environment. Warm lighting is more calming and inviting, Neutral white lighting provides the most efficiency, is best paired around windows and daily work environments. Cool lighting is more for high production environments, meeting rooms where alertness is needed, and sterile environments.
Color Temperature Comparison
The Kelvin scale for practical use ranges from 1,000-10,000K. 1,000K being red/orange to 10,000K being blue. The color temperature of a light is considered a color tint in that it tints white light, so there will always be some amount of white light mixed in. Opposed to a light that is an actual different color than white. Color temperature has a significant impact on environment so getting the color temperate correct for your environment is an absolute must.
