Guthman Signs: LED Display FAQs – Demystifying Common Concerns

This blog post aims to answer some of the most frequently asked questions regarding our LED displays, empowering you to make informed decisions.

Lead Times and Manufacturing:

  • Q: Do we have to wait for products from China?
  • A: No! We maintain a pre-stocked inventory of essential components right here in the USA. While all RGB pixel diodes are manufactured in China due to environmental regulations impacting US production costs, you won’t experience significant delays. Our typical lead time is 4-6 weeks after permitting, with an estimated 8-10 weeks to account for unforeseen circumstances.

Understanding LED Display Lifespan:

  • Q: A 10,000-hour MTBF (mean time before failure) seems low. Shouldn’t the display last longer?
  • A: It’s important to understand what MTBF signifies. In our case, it refers to the point when diodes begin to degrade slightly in brightness over time. This doesn’t equate to complete failure or dimness that can’t compete with sunlight. That’s where our high brightness rating (10,000 Nits) comes into play.

Here’s an analogy: A diode degrading at 7,500 Nits might become less visible in direct sunlight (around 2500-3500 Nits) sooner than a sign with 10,000+ Nit diodes.

  • Q: What’s the overall lifespan of the sign?
  • A: You can expect a lifespan of roughly 100,000 hours (10-11 years) at maximum white brightness. Automatic brightness sensors further extend this lifespan by adjusting brightness based on ambient light.

Features and Functionality:

  • Q: Can I schedule the sign to turn on and off at specific times?

  • A: Absolutely! Our cloud-based software allows you to create individual or playlist scheduling for your animations and graphics.

  • Q: Does the sign adjust brightness automatically?

  • A: Yes, it features an automatic light sensor that constantly monitors ambient light and adjusts brightness accordingly. This ensures optimal visibility while preventing excessive brightness at night. Additionally, a safety feature ensures the sign maintains 30% brightness if the sensor malfunctions.

  • Q: What about maintenance and repairs?

  • A: Our signs are designed for easy module replacement. The mapping software automatically adjusts for new modules, ensuring consistent luminance. Color balancing can also be achieved within the software. While some repairs might require an on-site technician, the software facilitates many troubleshooting processes.

Quality and Reliability:

  • Q: How long have you partnered with your current LED module manufacturer, and do you stock spare parts?

  • A: We’ve maintained a 14-year relationship with our trusted manufacturer. We stock spare modules here in the USA for your convenience. Their track record speaks for itself, contributing to our ongoing growth.

  • Q: Will replacement modules be available in 10 years?

  • A: Yes. Our warranty includes a 10-year parts availability guarantee, alongside a 5-year parts replacement policy.

  • Q: Can you diagnose and adjust sign issues remotely?

  • A: Yes, our team can offer remote diagnostics and adjustments for your LED sign.

Module Design and Installation:

  • Q: From where are the modules installed – front or rear?

  • A: Our signs offer front or rear serviceability. The modules consist of two parts: a frame and the LED screen itself. These can be detached using an Allen wrench for easy access.

  • Q: Is the power supply built-in or outboard?

  • A: Our signs incorporate a superior design. Unlike older models with exposed power supplies and connection points, susceptible to moisture and short circuits, our system utilizes insulated wires with secure IP67 connectors. Each module has an integrated Meanwell power supply and Novastar card, enabling self-communication and configuration. Additionally, passive cooling with an aluminum structure ensures efficient heat dissipation.
