LED neon sign buyer's guide: specs, sizes, installation

<p><strong>This is the technical buyer's guide to custom LED neon signs</strong> — what the specs actually mean (IP ratings, wattage, tube size), how to pick dimensions for your space, and how installation works. Written for business owners comparing options, without the jargon.</p>

<h2>The anatomy of a modern neon sign</h2>

<p>A Lumicorne sign is made of three parts: <strong>8 mm LED neon flex tubing</strong> (a silicone-sleeved LED strip that glows like glass neon, bent to follow your design), a <strong>transparent acrylic (PMMA) backing</strong> laser-cut to the outline of your artwork — not a rectangular panel — and a <strong>ready-to-plug power supply</strong> with 3 meters of cable. Fine details and color fills that can't be bent from tube are UV-printed directly on the acrylic, which is how complex logos stay faithful. Everything is CE-certified and tested lit before shipping.</p>

<h2>IP ratings: what "waterproof" really means</h2>

<p>An IP (Ingress Protection) rating has two digits: dust, then water. Our standard signs are rated for indoor use. The <strong>Waterproof option upgrades the sign to IP67</strong> — fully dust-tight and protected against temporary immersion — which in practice means permanent outdoor mounting through rain, snow and frost. If your sign lives indoors, even in a humid room, you don't need it; for facades, terraces, pool areas and spa corridors, you do.</p>

<h2>Power, lifespan, running cost</h2>

<p>A typical sign draws <strong>about 35 W</strong> — the consumption of a household bulb — on a 100–240 V supply. Lit 10 hours a day, every day, that's roughly <strong>€25 of electricity per year</strong>. LED lifespan is <strong>100,000 hours</strong>: over 25 years of daily commercial use. Unlike glass neon there is no gas, no high-voltage transformer, no heat and nothing to shatter: the tube is silicone, safe to touch, silent, and handles on/off cycles without wear (plug-in timers are fine).</p>

<h2>Choosing the right size</h2>

<p>Pricing and readability follow the <strong>longest side</strong> of your design; the height follows your artwork's proportions automatically and is displayed before purchase. Rules of thumb from hundreds of installations: <strong>60–80 cm (24–31 in)</strong> for storefront windows and interior walls read from a few meters; <strong>100–120 cm (39–47 in)</strong> for a main shop sign read from across the street; <strong>150–200 cm (59–79 in)</strong> for facades read from a road or parking lot. When in doubt, upload your logo on the quote page — the 3D mockup shows exact dimensions for every size.</p>

<h2>Colors and control</h2>

<p>Fixed-color signs reproduce your logo's exact colors (black and grey elements become white tubes — a tube must glow). The <strong>RGB option (+25%)</strong> makes tubes color-changing via the included remote, which also controls brightness and effects on every sign. Warm white flatters food, skin and fabrics; saturated colors maximize street visibility.</p>

<h2>Installation, step by step</h2>

<p>Every sign ships with <strong>3 mounting kits</strong> — through-screws for walls, standoffs for a floating look, and chains for hanging in windows (the glass is never drilled). Mark the holes using the sign itself, drill, mount, plug in: about fifteen minutes with a household drill, no electrician required. The power cable runs 3 meters to the nearest outlet; the supply is ready to plug.</p>

<h2>Shipping, warranty, support</h2>

<p><strong>DHL Express shipping is included</strong> (5 to 7 business days), with customs and taxes covered — the price you see at checkout is final. Every sign carries a <strong>2-year warranty</strong> on LEDs, power supply and remote, with after-sales support handled directly on WhatsApp by Pablo, our head of design and production. Payment by card, Apple Pay/Google Pay, or 3 interest-free installments with Klarna.</p>

<h2>Technical FAQ</h2>

<h3>Can it run in cold or hot climates?</h3>
<p>Yes — LED flex operates well below freezing and in summer heat. For outdoor exposure, take the IP67 Waterproof option; temperature itself is not the issue, water ingress is.</p>

<h3>What voltage do I need?</h3>
<p>The supply accepts 100–240 V, so it works worldwide; only the plug format changes. Signs ship with an EU plug — a standard travel adapter solves the rest, or contact us for your region.</p>

<h3>Can the acrylic be cut to any shape?</h3>
<p>Yes — the backing follows the outer silhouette of your artwork with a small uniform margin, like a die-cut sticker. Rectangles are possible but never required.</p>

<h3>How do I clean it?</h3>
<p>Unplug, wipe the acrylic with a soft dry or slightly damp cloth. No solvents. That's the entire maintenance schedule for 25 years.</p>

<h3>Is it repairable?</h3>
<p>Power supplies and remotes are replaceable parts (covered 2 years). The tube itself is a single bent run — in the rare case of damage, contact Pablo on WhatsApp with a photo and we'll sort the fastest fix.</p>
