How to Choose LED Strip Lights: A Step-by-Step Buying Guide
Quick Answer
To choose LED strip lights, work through six steps: decide the job and the brightness, measure the run, pick the voltage and strip type, calculate the power supply, choose the controller and plan the mounting. A simple rule is 300–600 lumens per metre for mood lighting and 800 or more for task lighting, with a power supply rated about 20% above the strip's total wattage. When you choose LED strip lights this way you avoid the usual problems of dim, uneven or failing strips, and a good 5 m reel with a supply costs $20–$60.
Key Takeaways
- Choose LED strip lights by the job first: ambient, task, accent or entertainment.
- Measure the run in metres, add spare for corners and connectors, and match the reel length.
- Choose 12V for short runs and 24V for longer ones, which lose less brightness.
- Work out total wattage and buy a supply rated about 20% higher.
- Plan mounting, controls and cable routes before you buy, not after.
Step 1: Decide the Job and the Brightness
Before you choose LED strip lights, decide what they are for, because the job sets the brightness, colour and type. If you want a deeper look at what separates good strips from poor ones, read our guide to good LED strip lights, and for colour choices see how to choose LED light colours for every room and the LED light colour temperature guide.
| Job | Brightness (lumens per metre) | Colour | Typical places |
|---|---|---|---|
| Mood and ambient | 200–600 | Warm white or RGB | Bedrooms, TV backs, behind furniture |
| Task | 800–1,200+ | Neutral white, high CRI | Under cabinets, workbenches, desks |
| Entertainment | 300–600 | RGB, RGBIC or music sync | Gaming setups, TVs, party spaces |
Step 2: Measure the Run Before You Choose LED Strip Lights
Use a tape measure along the exact path the strip will take, including turns and drops. Add 5–10% for corners and connectors, and note where you can reach power. Reels are usually 2 m, 3 m, 5 m or 10 m, and strips can be cut at marked points, so buy slightly more rather than less.
Step 3: Choose the Voltage and Type
| Voltage | Best for | Maximum run on one feed | Notes |
|---|---|---|---|
| 12V | Most home and vehicle uses | Up to about 5 m | Common and widely available |
| 24V | Long runs and brighter strips | Up to about 10 m | Less brightness drop; slightly higher cost |
When you choose LED strip lights for long runs, feed power at both ends or use 24V to keep the brightness even. Choose RGB for colour, RGBW for colour plus good white, and addressable (RGBIC) for effects.
Step 4: Calculate the Power Supply
Check the strip's watts per metre. As an example, 5 m of strip at 14.4 W per metre draws 72 W. Add 20% headroom (72 x 1.2 = 86 W) and choose a 100 W supply of the same voltage. At 12V, 72 W is 6 A, so the supply and wiring must handle at least that. Always use a certified supply and never exceed its rating, and do this sum before you choose LED strip lights, not after.
- Find watts per metre in the listing.
- Multiply by the length to get total watts.
- Add 20% for safety and longevity.
- Match the voltage of the supply to the strip.
Step 5: Choose the Controller
| Control | Pros | Cons |
|---|---|---|
| Simple remote | Cheap and quick | Needs line of sight; basic effects |
| App with Bluetooth | Many colours and scenes | Short range; app quality varies |
| Wi-Fi smart controller | Remote and voice control | Needs good Wi-Fi; more setup |
Step 6: Plan Mounting and Installation
Plan mounting before you choose LED strip lights, because channels and clips affect length and cost.
- Clean and dry the surface; textured or greasy surfaces need clips or channels.
- Use aluminium channels with diffusers for a smoother line and better heat control.
What to Expect at Each Price
Here is what you get when you choose LED strip lights at each price. For most homes, $20–$60 is enough.
| Price (5 m with supply) | What you typically get | Trade-offs |
|---|---|---|
| $10–$20 | Basic RGB strip with remote | Dimmer; weaker adhesive |
| $20–$60 | Brighter strips, app control, better chips and supplies | Good value for most homes |
| $60–$150 | High-density, high-CRI or addressable strips with quality controllers | Higher cost |
| $150+ | Architectural-grade or COB lighting | For permanent installs |
Safety Notes
Whenever you choose LED strip lights, put safety first.
- Use a certified power supply of the correct voltage and never overload it.
- Do not coil or cover powered strips; heat needs to escape.
- Unplug before cutting, joining or moving a strip.
Summary
To choose LED strip lights, define the job and brightness, measure the run, pick 12V or 24V and the right type, size the supply with 20% headroom, choose a controller and plan the mounting. Follow those steps and a $20–$60 setup will look neat and last. Taking a few minutes to choose LED strip lights properly saves you dim, uneven or overheated installations.

Frequently Asked Questions
How do I choose LED strip lights for a bedroom?
Pick warm white or RGBW at about 300–600 lumens per metre, a dimmer or app control and a diffuser channel if the strip will be visible.
How long can an LED strip be on one power supply?
About 5 m at 12V and 10 m at 24V before brightness drops noticeably, unless you feed power at both ends.
What power supply do I need?
One with the same voltage as the strip and a wattage about 20% above the strip's total draw.
Can I use LED strip lights outdoors?
Only if they have a suitable IP rating, such as IP65 or above, with sealed connectors and a protected power supply.
Do LED strip lights use a lot of electricity?
No. A typical 5 m strip uses a few dozen watts at most and costs very little to run.
