How to Choose LED Strip Lights: A Specifier's Checklist

If you want to choose LED strip lights that work the first time, the order of your decisions matters more than any single spec. Most of the problems we see on job sites started with a choice made too early. Someone picks a strip for its color temperature, then finds out it's the wrong IP rating for a bathroom. Or the aluminum profile gets chosen last and the strip doesn't fit it.

This checklist runs the decisions in the order that avoids that kind of rework.

1. Start With the Environment

Where the strip lives decides its protection before anything else.

IP68 describes a test, not an application. A strip can pass IP68 and still be the wrong choice for a pool, where chemicals, bonding and listing rules come into play. That's why ENKORA keeps purpose-built pool products in a separate UNDERWATER series. The IP ratings guide explains each digit.

2. Choose the Light Type

• Static white: one fixed color temperature per reel. It's the right answer for most architectural work.
• Tunable white: adjustable between warm and cool white on one strip, for rooms that change use through the day. See TUNABLE WHITE.
• Single color, RGB, RGB + white: for accent, hospitality and entertainment.
• Addressable (SPI): each segment controlled on its own, for chases and effects. See ADDRESSABLE / SPI.

3. Set the Color Temperature

A sensible starting point: 2700K for living spaces and hospitality, 3000K for kitchens and baths, 3500–4000K for offices and retail, and 5000K or higher for task-heavy or industrial spaces.

Then match the room. A 4000K strip under 2700K downlights looks like a mistake, even when each light on its own is fine. The color temperature guide covers the trade-offs.

4. Decide How Much Color Quality You Need

CRI 90+ is the practical floor for interiors people spend real time in. Where color matters, as in retail, galleries, restaurants or anywhere clients pick finishes, go to CRI 95+ and ask for the R9 value. R9 is saturated red, and the headline CRI number leaves it out. ENKORA's HIGH CRI 95+ series is built for that brief, and the CRI guide has the background.

5. Size the Light Output

Strip output is quoted in lumens per foot (lm/ft). Rough ranges:

Look at efficacy (lm/W) at the same time. It drives energy use, driver size and heat. If an energy code or a tight power budget shapes the design, start with HIGH EFFICACY. If the brief is simply more light, look at HIGH OUTPUT.

6. Pick COB or SMD

COB strips pack their chips so tightly that the line reads as continuous light, even without a diffuser. Use them wherever the strip, or its reflection in a glossy surface, can be seen.

SMD strips have individual LEDs. They usually offer higher efficacy and more build options, and they look their best behind a diffuser or deep in a profile. The COB vs SMD guide goes into detail.

7. Choose the Voltage and Check the Run Length

For most architectural work, specify 24V. At the same power it carries half the current of 12V, so voltage drop along the run is roughly halved and a single feed can serve a longer run. Save 12V for short runs and retrofits where 12V supplies are already in the wall.

Every strip also has a maximum run from a single feed. Go past it and the far end dims, and on some strips it shifts color too. Longer runs need a second feed or a strip designed for distance, like the LONG RUN series. Our article on voltage drop works through the math.

8. Fit the Strip to the Profile

Check the strip width against the profile's inside channel, and pick the profile first when you can, since it often sets the maximum width. Tight reveals and millwork details call for tape from 2.8 mm (about 1/8 in.) wide, which you'll find in the NARROW series.

Don't treat the aluminum as trim. It's also a heat sink, and a strip that runs cooler holds its output and color longer. See profiles and diffusers.

9. Plan Cut Points and Dimming

You can only cut a strip at its marked cut points. Check the cut length against the actual dimensions on the drawings, or specify a free-cut build that can be cut anywhere.

Settle the control method early too. Phase dimming, 0–10V, DALI and wireless controls each need a compatible driver, and swapping later is expensive. The dimming and control guide compares them.

10. Size the Driver and Confirm Listings

Load drivers to no more than 80% of their rating: run length × W/ft ÷ 0.8. The power supply calculator does this for you and checks the strip's own published maximum run.

Last, confirm what your jurisdiction expects. US inspectors typically look for a listed driver and a strip that's listed or recognized for the application. Ask for the listing in writing for the exact product you're buying. More in UL and ETL listings.

Mistakes That Cost the Most

• Ordering by the foot for a long cove. Buy the full quantity in one order so every reel comes from the same batch. Mixed batches can show as a visible tone change on a ceiling.
• Hiding the driver. A driver sealed behind drywall is a service call waiting to happen. Put it somewhere ventilated and reachable.
• Skipping the mock-up. A two-foot test piece with the real driver and dimmer takes ten minutes and catches flicker, color and glare problems before they're built in.
