LED lighting has come a long way from the cold, blue-toned bulbs we all cringed at a decade ago. Now, it’s everywhere—from office ceilings to warehouse bays to cozy restaurant corners. But just because LED lighting is popular doesn’t mean everyone’s buying it right. In fact, we see the same mistakes over and over again, and they can cost you money, comfort, and even safety.

At Rayvern Lighting, we’ve helped thousands of businesses and facility managers upgrade their lighting setups—and we’ve seen what works and what doesn’t. So if you’re planning to switch to LED (or just restock your supply room), here’s what you’ll want to watch out for before you hit “buy.”

Mistake #1: Ignoring Color Temperature

This one trips people up all the time. Color temperature, measured in Kelvins (K), affects how “warm” or “cool” your lighting feels. A 2700K bulb gives off a warm, cozy light—great for restaurants or waiting rooms—while 5000K is a crisp, daylight-style glow that’s perfect for task lighting or warehouses.

Problem is, people often mix color temps in the same space, which makes things look off. If your breakroom feels like a hospital exam room, color temperature might be the culprit. Make sure you’re picking the right tone for the vibe you’re going for—and sticking with it.

Mistake #2: Skipping Compatibility Checks

Not every LED plays nice with your existing dimmers, fixtures, or ballasts. Replacing a fluorescent tube with an LED one? You might need to bypass the ballast—or replace it with an LED-compatible version. Got dimmer switches? Make sure your LED bulbs are marked as dimmable, or you’ll be dealing with flickering and frustration.

This is where working with a trusted supplier (hi, that’s us) really makes a difference. We’ll help you match your new lights to your existing setup, so you’re not stuck with a return or retrofit headache.

Mistake #3: Buying Based on Price Alone

We all love a good deal, but with LED lighting, cheap can turn into costly. Lower-priced LEDs may have poor build quality, flicker over time, or burn out faster than expected. What you save upfront, you often pay for in replacements or energy waste.

At Rayvern, we stock commercial-grade products that are built to last—and we’ll guide you to the right fit without overselling. It’s about value, not just price tags.

Mistake #4: Overlooking Beam Angle

Beam angle controls how wide the light spreads. Narrow beams are great for spotlighting displays or workstations, while wide beams are better for general room lighting. Choosing the wrong one can leave you with shadowy corners or overlit spaces that feel harsh and uneven.

If you’re lighting a large commercial area or trying to make your office feel more welcoming, beam angle matters more than you think.
