Designing a media wall with LED lighting is exciting, but getting the lengths, power and sockets right can be confusing. The LED & Power Planner tool solves that by turning a few simple inputs into a clear, electrician‑ready plan.
LED & Power Planner Calculator – How to Use the Tool and Key Benefits
This page walks you through how to use every part of the LED & Power Planner and what benefits you get from using it.
What the LED & Power Planner Tool Does
The LED & Power Planner helps you:
- Decide where to run LED strips around your media wall
- Estimate the total LED length you need in metres
- Calculate wattage and power supply size for each zone
- Sense‑check how many sockets you’ll need and where they should go
- Turn everything into a simple brief you can share with your electrician, joiner or lighting supplier
Instead of guessing and hoping for the best, you get a structured plan that reduces mistakes, rework and extra visits.
Who This Tool Is For
The LED & Power Planner is ideal for:
- Homeowners planning a new TV/media wall
- Interior designers who want quick, consistent lighting specs
- Installers and electricians who need clear lengths and loads
- Joiners and cabinet makers designing bulkheads, coves and niches
You don’t need to be technical. The tool asks plain‑language questions and does all the calculations for you in the background.
1 – Tell the Tool About Your Wall and Room
Start by entering the basic details of your space. Typical inputs include:
- Wall width and height – the overall size of your TV wall
- Ceiling height – useful if you plan a LED cove at the top
- Room type – living room, snug, bedroom, open‑plan area, etc.
- How you use the room – movie nights, casual TV, gaming, family space
These simple inputs help the tool suggest realistic LED layouts and brightness levels that suit both the room and how you use it.
2 – Select Your LED Zones
Next, you choose where you want LED lighting on the media wall. Common zones include:
- TV halo – LEDs behind the TV for a soft glow
- Top cove lighting – a recessed channel at the top of the wall
- Vertical side channels – strips running up and down the sides
- Fireplace surround – LEDs around or above an electric fire
- Shelves and niches – lighting for display compartments
For each zone you can usually:
- Turn it on or off
- Tell the tool roughly how wide/tall that zone is
- Indicate if you want a subtle glow or a strong feature
The planner uses your wall dimensions to estimate how many metres of LED strip each zone will require.
3 – Check the LED Lengths and Layout Summary
As you choose zones and sizes, the LED & Power Planner automatically calculates:
- Strip length per zone (e.g. 4.2 m around the TV, 3.5 m in the cove)
- Total LED length across the whole media wall
- Layout notes you can share with your installer
This is your first key benefit:
You move from a rough idea in your head to a clear shopping list of LED lengths, before ordering anything or cutting timber.
4 – Understand Brightness and Colour Temperature Suggestions
The tool also helps you pick the right brightness and colour tone so the wall feels comfortable, not harsh.
Based on your room and usage it can suggest:
- Approximate lumens per metre (how bright the strip should be)
- Recommended colour temperature:
- Warmer whites for cosy lounges
- Neutral whites for family spaces
- Slightly cooler whites for modern, clean looks
You don’t need to know exact specs – you just learn what to ask for when buying LEDs (for example “around 10–12 W per metre at 2700–3000K warm white”).
5 – View Your Power and Driver Recommendations
One of the most important jobs of the LED & Power Planner is to size your power supplies.
Using your LED lengths and typical strip wattage, the tool estimates:
- Watts per zone (how much power each run of strip will use)
- Total load for the whole wall
- Suggested minimum driver / power supply size
- A sensible safety margin so the driver isn’t overloaded
Examples of what you might see:
- “TV halo: approx. 32 W – use a 50 W driver”
- “Top cove: approx. 45 W – use a 75 W driver”
This helps you and your electrician avoid:
- Undersized power supplies that overheat or fail early
- Oversized, expensive units that are unnecessarily big
6 – Plan Sockets, Feeds and Access
Good LED design isn’t only about light – it’s also about where the power comes from. The planner gives you guidance such as:
- How many switched fused spurs or sockets you’re likely to need
- Sensible locations (e.g. behind the TV, under the fire, in a side compartment)
- Where it’s helpful to keep a small service space for drivers and controllers
You can then screenshot or export this section as a simple power plan:
- Electrician sees where to bring feeds and controls
- Joiner knows where to leave access panels
- You know you won’t end up with a trailing plug hanging out of the side
7 – Turn the Output into an Electrician‑Ready Brief
At the end, you have a clean summary of:
- LED zones and approximate lengths
- Brightness and colour‑temperature guidance
- Power loads and suggested driver sizes
- Sockets and supply locations
You can share this with your:
- Electrician, to quote and wire accurately
- Lighting supplier, to match strip and driver specs
- Joiner, to build in channels, voids and access panels
The benefit is simple:
Everyone works from the same clear plan, and you massively reduce the risk of “we didn’t allow for that” moments during the build.
Key Benefits of Using the LED & Power Planner
- Confidence – You understand your LED layout before anyone cuts, wires or orders parts.
- Clarity for trades – Electricians, joiners and designers all see the same numbers.
- Cost control – You only buy the LED length and driver capacity you actually need.
- Better lighting effect – Brightness and colour suggestions help avoid glare and harsh light.
- Fewer surprises – Socket positions and access are considered up front, not as an afterthought.
Use the LED & Power Planner before you finalise drawings or place orders and turn a rough idea into a professional, well‑thought‑out media wall lighting plan.
