Before you buy anything

A few things worth knowing first

Decide on your sign size before ordering anything. A 12x18-inch sign uses about 3 meters of flex. A 24x36-inch sign needs 8-10 meters. Size determines how much flex, what power supply wattage, and how large an acrylic sheet you need. Sketch it first, measure the letter path length, then order.

LED neon is not glass neon. The material is flexible silicone-coated LED strip, not gas-filled glass tubing. You don't need a torch, ventilation, or specialized training. The aesthetic is very similar; the process is entirely different. Don't let the word 'neon' put you off.

12V is right for your first sign. 24V systems handle long runs better (10-plus meters), but almost any first sign fits within a 5-meter 12V setup. Power supplies, connectors, and accessories are all simpler and more widely available at 12V. Upgrade when you actually outgrow it.

LED Neon Flex Strip

The flex strip is the core material: a flexible tube of LED chips inside a silicone casing that bends around curves and cuts to length with scissors. Buy for the voltage you'll use (12V for most home signs), the color you want, and a profile width that matches your sign scale. Most beginner signs use 1cm or 1.5cm wide flex.

Best starter
ALITOVE

ALITOVE 12V LED Neon Sign Rope Light 16.4ft

$$

ALITOVE is a well-known LED brand with strong QC, and this rope light is explicitly made for DIY sign making. Silicone construction bends smoothly, cuts cleanly at the marked intervals, and the 5m length covers a 12-18 inch sign with room to spare. Available in warm white, red, blue, and other sign-ready colors.

What we like

  • Cuts cleanly at marked intervals without fraying the silicone
  • Flexible enough for tight lettering without cracking or kinking
  • Color stays consistent across multiple reels from the same batch

What to know

  • Color can shift slightly between different production batches
  • Connectors sold separately; plan to solder or buy matching pigtails
Budget pick
Torchstar

DC12V LED Neon Flex Strip Light for Signs 16.4ft

$

Explicitly marketed for signboard and logo making. High LED density (120 LEDs/m) produces a smooth, even glow and the warm white color is the most versatile for first signs. A solid learn-on option if you want to practice the build workflow before committing to premium flex.

What we like

  • Kit includes mounting clips, simplifying the very first build
  • Color is good enough for practice signs and learning the process

What to know

  • Included power adapter too weak for a full 5m run; replace it
  • Color accuracy inconsistent; not ideal for client work or gift pieces
Upgrade pick
BTF-LIGHTING

BTF-LIGHTING FCOB 24V High-Density Diffused Neon Light 16.4ft

$$$

The FCOB construction means 480 LEDs per meter with no individual hotspots — the light output is completely smooth and uniform, much closer to real glass neon than standard rope light. IP67 waterproofing also makes it the pick for window or outdoor-facing signs. Requires 24V; plan your power supply before ordering.

What we like

  • Even brightness end-to-end on runs over 5 meters
  • Less heat generation than 12V at equivalent brightness levels

What to know

  • 24V power supplies and connectors are harder to find locally
  • Overkill for a first sign under 18 inches; adds unnecessary complexity

Power Supply

Every LED neon sign needs a regulated DC power supply. Size it to at least 120% of your total flex wattage (a 5m strip of 12V flex typically draws 20-40W depending on density). MEAN WELL is the brand professional sign shops use. A cheap unbranded supply can fail mid-display or, worse, overheat.

Best starter
MEAN WELL

MEAN WELL LRS-50-12 Power Supply

$$

The 12V 4.2A (50W) MEAN WELL is what commercial sign shops reach for in hobbyist builds. Enclosed and ventilated, runs cool, and has a screw terminal block for clean wiring. At $20-25 it's a buy-once supply that handles any home sign under 50W, which covers most single-color 5m builds.

What we like

  • Industry standard; what commercial sign shops actually use
  • Screw terminal block gives clean, reliable connections
  • Runs cool and quiet even after hours of continuous display

What to know

  • Requires basic wiring; not plug-and-play like a wall adapter
  • Overkill for a tiny 1m sign where a cheap adapter does fine
Budget pick
ALITOVE

ALITOVE 12V 3A DC Power Adapter

$

A plug-in wall adapter works fine for small signs under 25W (roughly 3m of standard flex). No wiring required; just connect the barrel jack to a matching connector on your flex. The right call if you're making a single small sign and want to skip the terminal block entirely.

What we like

  • No wiring required; barrel jack connects directly to most flex kits
  • Compact and tidy for a single small display panel

What to know

  • Undersized for anything over 25W; real overheating risk above that
  • Barrel connector standard varies; confirm compatibility before buying
Upgrade pick
MEAN WELL

MEAN WELL LRS-100-12 Power Supply

$$$

When you're running multiple sections or building something larger than 24 inches wide, the 100W (8.5A at 12V) LRS-100 gives you the headroom. Same quality as the LRS-50, just bigger. Plan for it if you're making a 10-letter sign or anything with multiple independently wired sections.

What we like

  • 100W headroom handles multi-section and large-sign builds easily
  • Same MEAN WELL reliability; typically runs at 50% load or less

What to know

  • Significantly more expensive than the LRS-50 for most first builds
  • Physically larger; plan housing or backboard cutout accordingly

Backing Board

The backing board holds the flex in its designed shape and mounts to the wall. Clear acrylic is the classic choice (the floating-letter look comes from seeing through the backing). Black PVC foam board is lighter and easier to cut, which makes it the better first-project material. Both are available online and at local sign shops.

Best starter
CALPALMY

CALPALMY 12x24 Inch Clear Acrylic Sheet 1/8" (2-Pack)

$$

Clear cast acrylic is the standard backing for home neon signs. This 2-pack gives you one panel for the actual sign and one for practice cuts. At 1/8" thick it's light enough to hang with Command strips yet rigid enough for signs up to 18 inches wide. Score-and-snap cuts work for straight edges.

What we like

  • Transparent backing gives the classic floating-letter neon look
  • Score-and-snap cuts work for straight edges; no power tools needed

What to know

  • Cracks if drilled with a wood bit at high speed; use the right bit
  • Heavier than PVC foam board for the same panel surface area
Budget pick
Sintra

Sintra Black PVC Foam Board 12x24 Inch 3mm

$

Black PVC foam board cuts with a utility knife, weighs almost nothing, and hides the backing cleanly on dark-colored signs. Great for first projects where you want to focus on the flex-bending workflow rather than acrylic handling and drilling.

What we like

  • Cuts with a utility knife; no power tools or drill bits needed
  • Lightweight; easy to hang with standard picture-hanging hardware

What to know

  • Bows over 24 inches wide without a frame or cleat behind it
  • Non-transparent; you lose the floating-letter look on light walls
Specialty pick
DistinctAndUnique

DistinctAndUnique Frosted Acrylic Sheet 12x24 1/8"

$$$

Frosted acrylic diffuses the LED light before it reaches the viewer, softening harsh hotspots from the individual LED chips. The effect reads closer to real glass neon and less like a flex strip. Worth it for display pieces or gifts where the quality of the glow matters to you.

What we like

  • Diffuses LED hotspots into the smooth glow of real glass neon
  • Significantly higher perceived quality for display or gift pieces

What to know

  • Shows fingerprints; requires careful handling during assembly
  • More expensive per panel than clear acrylic of the same size

Bending and Layout Tools

LED neon flex is flexible but not infinitely so. For curves tighter than about 3 inches in radius (the inside of letters like C, S, or G) you'll need a heat gun to soften the silicone. You also need a printed template to shape the flex against, plus mounting clips to hold sections in place. These tools are cheap and reusable across every sign you'll ever make.

Best starter
SEEKONE

SEEKONE 1800W Heat Gun Variable Temp

$$

Variable-temperature 1800W heat gun with two speed settings. The low setting is enough to make the silicone pliable without melting it. Hold it 4-6 inches from the flex and keep moving continuously. The SEEKONE is consistent, available for under $30, and reliable enough that you won't burn a strip mid-bend.

What we like

  • Two temperature settings let you dial in heat for flex, not melting
  • 1800W heats up in under 30 seconds; no waiting around between bends

What to know

  • No fine temperature control between the two preset settings
  • Gets very hot; keep it moving and pointed away from power cords
Budget pick
Samsion

Samsion LED Neon Flex Mounting Clips 100-Pack

$

Snap-in clips hold the flex strip against the backing while you position and adjust the design before securing it permanently. At $8-12 for 100 clips, you have enough to prototype a full sign twice over. These also work as the permanent fastener for flex that doesn't need routing into a channel.

What we like

  • 100 clips covers a full 5m sign with plenty of extras
  • Snap-in design holds flex firmly without glue or fasteners

What to know

  • Sized for a specific flex profile width; confirm before ordering
  • Plastic yellows under UV after years of outdoor sun exposure
Specialty pick
Muzata

Muzata Bendable Aluminum LED Channel 1M (10-Pack)

$$

If you want the finished, commercial look you see in bar signage, aluminum channel holds the flex and hides all the clip hardware. The 10-pack gives you enough channel to do a full sign with sections to spare. Cut to length with a hacksaw, mount to the backing, and drop the flex in.

What we like

  • Professional finish; hides clips and gives the flex crisp edges
  • Aluminum acts as a minor heat sink, extending LED lifespan

What to know

  • Requires a hacksaw and more installation time than simple clips
  • Adds 4-6mm to the sign's depth; plan standoff length accordingly

Mounting Hardware

Your finished sign needs to float off the wall. The gap behind the backing hides the power cable run and is part of the classic neon sign aesthetic. Clear acrylic standoffs (also called barrel standoffs) are the standard solution: four screws hold the backing 1-2 inches off the wall and disappear visually. For lighter signs, heavy-duty adhesive strips work just as well.

Best starter
Unbranded

Sign Standoff Screws for Acrylic Mounting 0.75in (20-Pack)

$

Metal standoffs are the standard mounting hardware for DIY neon signs. Four standoffs at the corners hold the backing off the wall, the power cable routes behind out of sight, and the hardware gives a clean, finished look. The 0.75-inch depth keeps the sign close to the wall without a gap that looks unintentional.

What we like

  • Standard sign mounting hardware; four corners hold most sign sizes
  • Creates the floating-sign gap that hides the power cable behind

What to know

  • Requires pre-drilling the acrylic; wrong bit or speed cracks the panel
  • Needs wall anchors in drywall; the screws alone won't hold long-term
Budget pick
Command

Command Large Picture Hanging Strips

$

For lighter signs under 5 lbs, Command strips are the no-drill option. Clean installation and removable without wall damage. Most finished neon signs with acrylic backing run 3-5 lbs, right at the Command heavy-duty limit. Good for renters or finished spaces where drilling isn't an option.

What we like

  • No drilling required; removable without damaging the wall surface
  • Fast installation; fully set in one hour

What to know

  • Fails in humidity; not for bathrooms or laundry rooms
  • Heavy acrylic signs over 5 lbs push the weight rating uncomfortably

Save your money

What you don't need yet

Beginners get pressured to buy a lot of stuff that doesn't help them play better. Here's what we'd skip on day one.

  • Glass neon equipment — Real glass neon requires a gas torch, bombarding unit, vacuum pump, and years of training. It is a completely different craft from LED sign-making — don't conflate the two.
  • A laser engraver or Cricut — Print your template on paper and trace it. Cricut and laser add precision but the first-sign workflow is manageable without them.
  • RGB controller or color-changing flex — Single-color static signs are simpler to wire and build. Save color-changing for sign number three, once you know the basic workflow.
  • A commercial power panel enclosure — A $20 MEAN WELL supply handles anything you'll build in your first year. Professional panel enclosures are for installation-grade work.
  • A CNC router — Hand-routing channels with a Dremel or using mounting clips works fine for the first ten signs. CNC is a quality-of-life upgrade, not a prerequisite.

FAQ

Common questions

What is LED neon flex, and how does it differ from glass neon?

LED neon flex is a flexible tube of LED chips inside a silicone housing that mimics the look of gas-filled glass tubes. Glass neon uses a torch, gas, and years of apprenticeship to shape; LED flex bends with a heat gun and cuts with scissors. The finished look is very similar; the process is completely different.

How much does it cost to make a first sign?

A 12x18-inch sign with acrylic backing, 3-4m of 12V flex, a MEAN WELL LRS-50-12, and standoffs comes to $150-200. A larger 24x36-inch sign needing 8-10m of flex runs $250-350. The tools (heat gun, drill bits, clips) are reusable indefinitely. Budget $150 for your first build; $200 if you want no stress about running short.

Do I need to solder to connect the flex to a power supply?

Not necessarily. Most 12V neon flex uses a barrel connector (the same round plug on laptop chargers). If your flex has a barrel connector and your supply has a matching socket, it's plug-and-play. MEAN WELL supplies use screw terminal blocks instead, which require stripping the wire but no soldering at all.

How do I bend flex around tight corners inside letters like C, S, or O?

Warm the silicone with a heat gun on its low setting held 4-6 inches from the flex, moving continuously. After 10-15 seconds the flex becomes pliable and holds its shape once it cools. For very tight curves (inside radius under 2 inches), make multiple short heat passes rather than one long one.

Can I cut the flex to any length?

Yes, at the marked cut points. Most LED neon flex has cut marks every 1-2 inches where the LED circuit repeats. Cut between the LEDs at the marked line to avoid breaking a circuit midway through. Cap the cut end with a matching silicone end cap to keep out dust and moisture.

How do I figure out what wattage power supply I need?

Multiply the wattage-per-meter of your flex by the number of meters you're running, then multiply by 1.2 for safety headroom. Example: 5m of 8W/m flex = 40W total, times 1.2 = 48W minimum. The MEAN WELL LRS-50-12 (50W rated) covers that exactly with a little room left over.
