IP67 vs IP68 LED Modules: How to Choose the Right Protection for Outdoor Signage

What IP67 and IP68 Actually Mean

IP stands for Ingress Protection. The two digits after it tell you how well a product is sealed against solids and liquids.

• First digit (6) = completely dust-tight. Both IP67 and IP68 block all dust and fine particles.
• Second digit (7) = protected against temporary immersion in water up to 1 meter for a limited time, usually 30 minutes.
• Second digit (8) = protected against continuous submersion at depths and durations specified by the manufacturer, typically under pressure.

In short, both ratings are excellent for outdoor use, but IP68 is built for conditions where the module may sit in water or face heavy, prolonged exposure.

IP67 LED Modules: The Right Choice for Most Outdoor Signs

For the majority of channel letters, light boxes, and sign cabinets exposed to normal outdoor weather, an IP67 LED module provides the right balance of protection, performance, and cost. It handles rain, snow, dust, and direct hose-downs during maintenance without issue.

HansonLed's IP67 range includes the TM/TE series, designed for standard outdoor signage such as storefront channel letters, shopping mall directories, and restaurant signs. These modules use reliable SMD LED technology, offer consistent color temperature, and are available in multiple power options to match different sign depths and brightness requirements.

IP68 LED Modules: Maximum Sealing for Demanding Environments

Some projects push hardware to the limit. If your sign is located in a flood-prone area, mounted near a fountain, used on marine applications, or buried in outdoor displays where water can pool for long periods, IP68 is the safer investment.

HansonLed's TS series IP68 modules are sealed to withstand continuous water exposure. They are commonly chosen for waterfront retail, amusement parks, outdoor wayfinding in tropical climates, and any installation where maintenance access is difficult and failure would be expensive.

How to Pick the Right Rating for Your Project

Choosing between IP67 and IP68 is not about buying the highest number available. It is about matching the module to the real-world conditions of the installation.

• Look at water exposure, not just weather. Rain and snow affect most signs, but only signs in standing water need IP68.
• Consider maintenance access. If the sign is high up or hard to reach, IP68 reduces the risk of water damage over time.
• Match the rating to the warranty period. A sign expected to last many years in a harsh climate benefits from stronger sealing.
• Balance cost and risk. IP67 covers the vast majority of outdoor signage. Only pay for IP68 when the environment justifies it.

When in doubt, a reliable LED module supplier can review your project drawings and recommend the best series.

Beyond IP Ratings: What Else to Check

IP rating is only one part of a dependable sign. A well-sealed module still needs quality LEDs, stable drivers, good thermal management, and consistent color. HansonLed manufactures its modules with advanced SMD LED technology, operates certified production lines, and holds ISO9001, CE, RoHS, PSE, UL, and Reach certifications.

We also offer OEM and ODM services, including custom sizes, logos, colors, and packaging. Whether you need a standard channel letter LED module, a high-voltage option for long runs, or a compact mini module for tight letters, our R&D team can adapt the product to your specifications.
