If we've said it before, we'll say it a thousand times. The lighting industry is confusing. Between the countless manufacturers, types of lamps, product names, and descriptions – navigating through it all is no small task. That's why we're here.
Acronyms can be overused or flippantly thrown about in conversations – especially in the commercial lighting industry. But that can leave people disoriented and blank. Typically, if I'm in that situation, I feel tempted to just nod along, pretending I know what the other person is talking about.
To clear up any confusion, we've pulled together the top 10 lighting acronyms you need to know.

1. CRI - Color Rendering Index
Many product descriptions state the CRI rating, so if you're ordering new products for your retail store, restaurant, or commercial building, it's important to understand what it means. Color rendering index measures the visual effect a light source has on the perceived color of the objects it illuminates. In plain English: as a rule of thumb, the higher the CRI, the better objects and colors should look under the light. For a more detailed explanation, check out our article covering how you should go about choosing CRI.
2. CCT - Correlated Color Temperature
CCT, or Correlated Color Temperature, is measured in Kelvin and indicates whether a lamp has a warm, mid-range, or cool color appearance.
3. HID - High Intensity Discharge
You may already purchase HID lamps, but do you know what HID stands for? High Intensity Discharge. HID lamps have an arc passing between two electrodes in a pressurized tube which causes various metallic additives to vaporize and release large amounts of light. I know, that sounds pretty scientific. Just remember, they produce a lot of light for your space and offer good energy efficiency and life compared with the volume of their light output.
4. LED - Light Emitting Diode
LED is perhaps one of the most widely used acronyms in the lighting industry. LED is also an extremely important term to know. Plus, you can sound pretty smart if you whip out the full term – light emitting diode – when talking with someone.
5. MOL - Maximum Overall Length
This is a buzzphrase you might hear from a lighting manufacturer's sales rep. MOL stands for Maximum Overall Length. It is the overall length of a lamp, from the top of the bulb to the bottom of its base. This can be helpful in making sure a replacement bulb looks right or fits in a specific fixture.
6. OSI - Osram Sylvania, Inc.
You'll commonly hear the lighting industry, as well as many Regency employees, refer to the manufacturer Osram Sylvania as "OSI". Osram just sold its lamps business – which was rebranded as "LEDVANCE" earlier this year – to MLS Ltd., Co.
7. PAR Lamps - Parabolic Aluminized Reflector Lamps
A PAR lamp is a lamp with the outer bulb formed from two pressed glass parts that are fused or sealed together, creating a reflector, which casts the light toward the object that it's aimed at. PAR lamps can be either incandescent, halogen, or HID. You'll commonly see these used in retail, restaurant, hotel, office, and many other lighting applications.
8. PLC - Philips Lighting Co.
Philips is often abbreviated to PLC. We commonly reserve this for internal use and rarely mention it in conversation with you.
9. ROI - Return on Investment
This is a common acronym no matter the industry you're in. And it's also probably the acronym you care most about knowing. In essence, Return on Investment percentage can help you rank which projects will turn out to be the best investments for your business.

10. TCP - Technical Consumer Products
Though a big time lighting manufacturer for more than 20 years, you'll rarely ever hear TCP referred to by their actual name – Technical Consumer Products. But don't you like knowing what it is, anyway?
