LED Sign Lighting

LED sign lighting keeps a business visible long after sunset. Whether you are building channel letters, retrofitting a light box, adding a neon-style logo to a window or washing a façade with colour, the right LED components make the message bright and readable from the street. This page gathers what sign makers, electricians and business owners need: LED neon flex, outdoor strips and modules, floodlights and wall washers.

Homeowners use the same parts on a smaller scale: a lit house number, a neon word above a home bar, a stone wall at the entrance of a property. Below, you will find each product type, the specs that matter in the Canadian climate and practical installation tips.

Four ways to light a sign with LED

LED neon flex for letters and logos

LED neon flex gives the glow of traditional neon without glass tubes or gas. A silicone extrusion diffuses the diodes into one smooth line, and the profile bends to follow script lettering, arcs and outlines.

For colour signs, the Ultraflex RGB neon (24 V DC, 15 W/m, IP66, dimmable) comes in a 6 m (20 ft) roll. Single-colour commercial-grade neon at 9.6 W/m uses UV-protected silicone, and top-bend Type XA neon (24 V DC, IP67, 8 W/m) is sold in custom lengths in 2700 K or 3000 K. Finish the job with neon accessories such as power feeds and flexible mounting track.

Outdoor strips and modules for light boxes and channel letters

Inside a light box or a channel letter, the goal is even brightness behind the face, with no hot spots. LED sign modules are spaced across the back of a cabinet or inside each letter, while outdoor LED strips suit shallow boxes, edge lighting and awning signs.

COB (chip-on-board) tape gives the smoothest line when the face is close: 24 V DC with 480 LEDs/m, 10 W/m and CRI 90, or 12 V DC at 5 W/m. For long runs, the CANOLIGHT 8 mm COB strip delivers 8 W/m and 640 lm on a 10 m roll rated IP67.

Floodlights for signboards and billboards

A sign that is not lit from inside is lit from the front. LED floodlights range from a 12 V AC 10 W model in warm 3000 K for an address plaque to 450 W fixtures for large billboards. The CSC LED FLM02 mini floodlight offers 20 W, 30 W or 50 W, selectable 3000 K, 4000 K or 5000 K and 120-347 V input. Floodlight accessories such as visors control spill and glare, while slip fitters and pole mounts put the beam on the whole sign face.

Wall washers for façades and lettered walls

When the sign is the wall itself, such as painted lettering or a stone monument, a wall washer spreads light evenly across the surface. The 48 in RGBWW linear wall washer bar runs on 120 V AC, is outdoor rated and DMX capable, so it can hold a brand colour or change scenes. A 12 in (30 cm) extension bracket widens the wash, and outdoor white or RGB bars of 112 cm and 36 W suit smaller façades.

Specs that matter for sign lighting

A sign runs long hours through rain, snow and freeze-thaw cycles. Compare these points before you buy:

• Voltage: most strips and neon here run on 24 V DC, which allows longer runs with less voltage drop than 12 V. Floodlights connect to 120-347 V.
• IP rating: IP22 is for dry indoor spots. Outdoors, choose IP65 (water jets), IP66 (powerful jets) or IP67 (temporary immersion).
• Colour: 3000 K is the most common choice and looks warm; 4000 K and 5000 K read crisper on white faces. RGB and RGBWW create colour, and CRI 90 keeps brand colours faithful.
• Certifications and dimming: look for cUL or CSA marks on line-voltage products and DLC on commercial floodlights. Dimmable neon lets you tone a sign down at night.

How to choose and install sign lighting

Size the power supply

Add up the wattage of every run, then pick a power supply or LED driver with headroom above that load. A 33 ft roll of ARANI 24 V FlexiTube at 5 W per foot, for example, draws 165 W. Mount the power supply in a dry, ventilated spot.

Protect every connection

Water usually gets in at the connections, not along the strip. Use the power feeds made for your neon profile, seal cut ends and route cables so water drips away. The guide on how to choose LED strip lights covers COB vs SMD, 12 V vs 24 V and IP ratings.

Automate it

A photocell switches the sign on at dusk and off at dawn. RGB neon and strips change colour with a controller, and DMX wall washers can join a programmed façade scene.

Commercial and residential uses

Storefronts usually combine a light box or channel letters over the entrance, a neon-style logo in the window and floodlights on a pylon sign at the parking lot. Restaurants and bars often choose warm 2700 K or 3000 K neon, while clinics and offices lean toward 4000 K or 5000 K. For the rest of the store, see LED retail store lighting. At home, 24 V products make house numbers and bar signs easy to build.

FAQ

What lights go inside a light box sign?

Most light boxes use LED sign modules or outdoor LED strips on the back panel. Modules space evenly in deep cabinets, while COB strips give the smoothest result in shallow boxes. Choose IP65 or higher outdoors.

Can LED neon flex replace a glass neon sign?

Yes. It reproduces the continuous glow of neon in a flexible silicone body, without fragile glass or gas. It runs on 24 V DC, is dimmable in most versions and is rated IP66 or IP67 for exterior lettering.

What are the best outdoor sign lights for a flat signboard?

LED floodlights aimed from above or below, with visors to keep the light on the sign and out of drivers' eyes. Models with selectable wattage and colour temperature, like the FLM02, make fine-tuning easy on site.

Should I use 12 V or 24 V for a sign?

For most signs, 24 V. It supports longer runs from one power supply with less voltage drop, so the far end of a letter stays as bright as the start. 12 V remains handy for short decorative runs.

Can a sign change colour or turn on by itself at night?

Yes. RGB neon flex and RGB strips change colour through a controller, and the RGBWW wall washer bar is DMX capable. Add a photocell and the sign switches on at dusk and off at dawn.
