| 2 | Halo-Lit Reverse Channel Letters | LEDs illuminate the wall behind each letter, creating a soft floating halo effect rather than direct face lighting. | Aluminum or stainless-steel body, acrylic back, rear-mounted LEDs | 50–120 mm | 5–14 W per 300 mm letter | Usually IP65 or higher | 50,000–80,000 hours | US$110–420 | 12–22 working days | Premium façades, hospitality, corporate entrances | High | Wall color and mounting distance strongly affect the halo; verify standoff brackets and rear heat dissipation. |
| 3 | Face-Lit and Halo-Lit Combination Letters | Direct front lighting is combined with rear halo lighting for stronger visibility and a layered nighttime appearance. | Aluminum body, acrylic face, rear LEDs, internal dividers | 100–180 mm | 12–25 W per 300 mm letter | Usually IP65–IP67 | 50,000–80,000 hours | US$150–550 | 15–25 working days | Flagship stores, casinos, resorts, landmark entrances | High | Require separate circuits or dimming controls when independent brightness adjustment is needed. |
| 4 | Edge-Lit Acrylic Letters | Light is injected through acrylic edges, producing a clean, modern glow with a relatively slim profile. | Laser-cut acrylic, aluminum frame, LED edge modules | 20–60 mm | 3–10 W per 300 mm letter | IP54–IP67, depending on enclosure design | 40,000–70,000 hours | US$80–300 | 8–18 working days | Interior branding, reception areas, malls, galleries | Medium–High | Inspect polished edges, optical uniformity, acrylic protection, and resistance to yellowing or cracking. |
| 5 | Front-Lit Metal Channel Letters | Metal faces or trims frame a translucent insert, giving a durable architectural appearance with controlled light output. | Aluminum or stainless steel, acrylic or polycarbonate face, LED modules | 80–180 mm | 8–20 W per 300 mm letter | Usually IP65–IP67 | 50,000–80,000 hours | US$130–500 | 15–30 working days | Airports, commercial buildings, premium retail, public venues | Very High | Compare metal gauge, corrosion treatment, weld quality, powder-coat adhesion, and face retention method. |
| 6 | Exposed Neon-Style LED Letters | Visible LED tubes or modules follow the letter outline, recreating a classic neon appearance with lower operating voltage. | Aluminum frame, silicone LED tube or exposed LED modules, acrylic supports | 30–80 mm | 6–18 W per 300 mm letter | IP65 for outdoor-rated tube systems | 30,000–50,000 hours | US$100–450 | 12–25 working days | Restaurants, entertainment venues, event spaces, hospitality | Medium–High | Check tube bending accuracy, color uniformity, connector sealing, mounting clips, and replaceability. |
| 7 | LED Neon-Flex Outline Letters | Continuous flexible LED tubing follows the complete outline, creating smooth lines without individual point-light hotspots. | Flexible silicone diffuser, aluminum backing, LED strips or modules | 25–70 mm | 5–16 W per 300 mm letter | IP65–IP68 versions are available | 30,000–60,000 hours | US$120–500 | 12–25 working days | Decorative façades, exhibitions, restaurants, photo zones | Medium–High | Verify bend radius, silicone hardness, color bin consistency, end-cap sealing, and outdoor UV resistance. |
| 8 | Back-Lit Metal Letters with Cut-Out Faces | Light passes through precision-cut openings or symbols in a metal face, producing a sharp graphic effect. | Powder-coated aluminum or stainless steel, internal LED modules, translucent diffuser | 60–140 mm | 6–16 W per 300 mm letter | Usually IP65 or higher | 50,000–80,000 hours | US$140–520 | 15–30 working days | Architectural signage, offices, museums, public buildings | High | Check cut-out precision, burr-free edges, light-blocking treatment, internal reflectivity, and drainage design. |
| 9 | Illuminated Fabric Tension Letters | A lightweight tensioned fabric face creates a broad, soft, low-glare illuminated surface, often with tool-free face access. | Aluminum frame, tension fabric, LED bars or modules, rear panel | 80–200 mm | 8–22 W per 300 mm letter | IP54–IP65, depending on fabric and enclosure | 40,000–70,000 hours | US$160–650 | 18–35 working days | Large interiors, showrooms, trade fairs, transport terminals | Medium–High | Evaluate fabric tension, wrinkle resistance, color reproducibility, frame rigidity, and cleaning requirements. |
| 10 | Illuminated Bulb-Style Giant Letters | Large freestanding letters use visible LED bulbs or low-voltage lamps for a retro, event-oriented appearance. | Aluminum or steel frame, acrylic or metal face, LED bulbs, internal wiring | 150–400 mm | 20–80 W per 1 m letter | IP44–IP65, depending on bulb and enclosure selection | 20,000–50,000 hours | US$250–1,200 | 15–35 working days | Events, weddings, festivals, retail displays, public installations | Medium | Confirm base stability, anti-tip provisions, cable protection, bulb replacement access, and electrical certification. |
