If you want a storefront sign that works, front-lit does the job for $20-80 per letter from my factory.
If you want an upscale, architectural look that makes a building feel expensive, back-lit halo letters are the move at $35-120 per letter. They cast light onto the wall and read premium. Rimless letters give a cleaner face, but they won't light the night as bright. Dual-lit does both; costs more, but some clients ask for day-and-night visibility.
Now let's dig into the details so you don't order the wrong thing and waste 15 days of production time.
Front-lit channel letters have an acrylic face that glows. They're the standard for strip malls, restaurants, retail stores, gas stations.
We build these with 2mm or 3mm acrylic faces, depending on letter height. Under 2.5 meters, 3mm is fine. Over that, we force 5mm or it caves in. The returns are usually 1.0-1.5mm aluminum or stainless. The LEDs sit inside the can, facing out. We use front-lit channel letters with SMD 2835 modules at 100-150 lumens per watt. That's the industry standard for a reason: bright, cheap, and reliable if you use Samsung, Osram, or Blueview modules. Cheap modules last 12-18 months. Then you get dark spots, and the client calls you screaming.
Factory price: $20-80 per letter. A full storefront sign of 10 letters usually lands between $200 and $800 product cost, before shipping and tariffs.
Here's what nobody tells you: the acrylic face yellows. Domestic acrylic starts yellowing in 1-2 years. UV-resistant Mitsubishi or Degussa acrylic lasts 5-8 years outdoors. If your client signs a 5-year lease, don't be the guy who installed cheap domestic faces. You'll be replacing them before the lease ends.
Color temperature matters more than you think. 3000-3500K warm white for restaurants and hotels. 4000-5000K neutral for corporate and retail. 6000-6500K cool for industrial and highway signs. I've had clients order 6000K for a steakhouse because it was brighter. It made the logo look like a morgue. Match the kelvin to the brand, not to your personal preference.
Back-lit letters, also called halo-lit, don't have a lit face. The face is solid—often acrylic, aluminum, or stainless—and the light spills out the back onto the wall. That halo effect is what makes a bank, law firm, or corporate HQ look expensive.
We build back-lit halo letters with 304 stainless steel returns if the client wants 10+ years, or aluminum returns for lighter weight. The LEDs mount inside the can, facing backward. We use a 20-25mm standoff from the wall so the halo has room to breathe. If you install them flush, the halo chokes, and you get a sad little glow that looks broken.
Price: $35-120 per letter. The premium over front-lit comes from the extra fabrication: clean returns, hidden mounting, and often a more precise weld because any imperfection shows in the halo shadow.
The ugly truth is many sign shops sell "halo-lit" for double the price by using cheap front-lit cans, flipping the LEDs backward, and calling it a day. That works for about six months. Then the silicone fails, water gets in, and the owner has a stained wall. We use neutral silicone, not acid-cure, on every seal. Acid-cure eats the LED coating. Most shops don't know that.
If you want outdoor non-lit letters that survive abuse, our stainless steel letters start at $15-40 per letter. Solid 304, no LED to fail. Sometimes the simplest answer is the right one.
A front-lit channel letter installed by a U.S. sign company runs $200-700 per letter. Halo-lit runs $400-1,000 per letter. That's installed, with permits and labor.
From my factory in Lu'an, Anhui, the product cost is $20-80 for front-lit and $35-120 for halo-lit. You save 50-65% on product. Shipping is extra: express for small orders at $30-100, air freight at $4-12/kg, sea freight for volume at $80-200 per cubic meter LCL. Add the U.S. Section 301 tariff of about 30% on signs. Even with that, a local shop can double or triple their margin by importing.
I've seen this go wrong: a contractor ordered 40 front-lit letters to save money, ignored our advice to pay for the plywood crate, and the letters arrived looking like a truck ran over them. We pack every export order with foam, carton, and a plywood crate. If you try to cheap out on packaging, the savings disappear in freight claims.
Here's what nobody tells you: tariffs and shipping add 30-40% to your landed cost. Any factory quote that doesn't spell that out is lying to you. We quote FOB Lu'an, and we tell you the estimated freight on the same email. No surprises.
Every factory says they use Samsung LEDs. Ask for the module spec sheet with the bin number and manufacturer date. 90% of the time, they're using recycled chips or no-name modules rated for 12-18 months.
Quality LED modules—Samsung, Osram, or Blueview—last 5+ years in real conditions. We rate L70 at 50,000 hours. That means after 50,000 hours, the light output drops to 70% of original. That's about 5.7 years if you run them 24/7. For a store open 12 hours a day, that's over 11 years. We warranty our LEDs for 2 years and power supplies for 1 year. If a power supply dies, it's usually a $15 Mean Well replacement. The cheap no-name drivers are what kill signs.
Here's what nobody tells you: IP65 is the minimum for outdoor signs. That means dust-tight and protected against water jets. It does not mean your sign survives a hurricane. For coastal areas, use IP66 or IP68-rated power supplies. In Miami Beach, the salt air will eat a standard steel sign in 3 years. Use 316 stainless, which contains 2-3% molybdenum and costs 20-30% more than 304. For a strip mall in Ohio, 304 is fine. For Miami, pay for 316.
Acrylic faces: we use UV-resistant Mitsubishi or Degussa on request. Domestic acrylic is cheaper but yellows in 1-2 years. Light transmittance for good acrylic is 90-92%. If you see 95% claims, they're measuring in a lab, not after two summers outside.
Stainless steel: 304 is 18% chromium, 8% nickel. Outdoors, 10+ years. Brushed #4, mirror #8, PVD, powder coated. We bend and weld it TIG. 316 adds molybdenum for marine grade, 15+ years. For aluminum letters, we use 1.0-1.6mm sheet, anodized or powder coated. Aluminum weighs 1/3 of steel and is naturally rust-proof, but it dents easier. If the sign is within arm's reach, go stainless.
Look, I'll tell you straight: we can't make a 2-meter-tall channel letter in one piece with no seams. Anyone who says they can is welding seams you'll see from the street. Our laser cutting has ±0.1mm accuracy. TIG welding leaves a seam that gets ground and polished. For a sign on a wall 10 feet up, it's invisible. If you need a seamless museum piece, that's not a channel letter, that's cast metal or routed aluminum. We do those too, but the price changes.
Tactile signs under ADA need to mount 48-60 inches from floor, have non-glare finish, and Grade 2 Braille. Channel letters with lit faces are not ADA signs. They're wayfinding or building identification. Check your local code. In the U.S., any electric sign must follow NEC Article 600. That means proper disconnects, grounding, and listed components.
UL 48 certification costs $4,000-15,000 and takes 4-9 months with quarterly audits. ETL is an alternative that's 10-30% cheaper. My factory has CE, RoHS, and ISO 9001. We can do UL or ETL on a per-order basis, but the cost and time get added to your quote. If a factory tells you they already have UL 48 and the quote is $50 per letter, ask to see the certificate with today's date. They're lying.
I've seen this go wrong: a contractor installed a halo-lit sign without a GFCI-protected circuit. Water got into the power supply, tripped the breaker, and the building owner thought the sign was broken. We trouble-shoot at 2 a.m. via WhatsApp because the contractor didn't read the IP rating. Outdoor power supplies need to be in a waterproof enclosure, not just zip-tied to the wall behind the sign.
Our 10-step process: design confirmation, laser cutting, bending/welding, grinding/polishing, acrylic face CNC, LED assembly, silicone sealing, 8-12 hour aging test, 100% QC inspection, and export packaging.
That's why lead time is 7-15 days after you approve the drawings. Not 30 days. Not "maybe next month." If you send a clean vector file on Monday, we can ship by the following Monday. Rush orders screw up QC. I'd rather lose a rush order than ship a sign with a cold solder joint.
We can build front-lit, back-lit halo, rimless, and dual-lit channel letters from 2 inches to 10 feet tall. We can do custom shapes, logos, and color-changing RGB with SMD 5050 modules. We can ship one sign or a container load. MOQ is one piece. Lead time is 7-15 days after design approval.
We cannot guarantee a 5-day rush if you haven't approved the drawings. We cannot make a sign that is both completely invisible by day and blazing by night. We cannot give you a quote without seeing the artwork, because letter height, stroke width, and material change the price by 3x. We cannot pay your tariffs or deliver a sign that installs itself.
Look, the factory-direct model works if you know what you're ordering. If you send us a vector file and tell us the application, we'll spec the right acrylic, LED, and return thickness. If you just ask for "channel letters, best price," you'll get exactly what you deserve.
For retail, gas stations, convenience stores, and restaurants: front-lit channel letters. They're the cheapest, brightest, and easiest to permit. Use 3mm UV acrylic, 2835 LEDs, and a raceway mount. Budget $20-80 per letter product cost.
For law firms, medical offices, corporate lobbies, and hospitality: back-lit halo letters. They're more expensive, but they sell the job at a premium. Use 304 stainless returns, 2835 LEDs, and 20-25mm standoffs. Budget $35-120 per letter product cost.
For clients who want both day and night visibility with a high-end look: dual-lit channel letters. They're the most complex and cost the most. We can build them, but don't quote a client without seeing the wall and the power access.
If you're a sign shop owner or contractor importing for the first time, order one sample letter. We'll ship it express. Check the weld, the acrylic, the LED module. Then place a container order. The sample costs you $30-100 in shipping, but it saves you from a $10,000 mistake.
