FAQ

Aviation LEDs

What makes PWI aviation LED lighting products superior to other options?

PWI LED lights are backed by FAA PMA and STC Certifications. Additionally, we are an approved Part 145 Repair Station. Each product utilizes superior components to make our high quality finished product.

A simple example is that our LED reading lights work down to an input of only 9 volts (normal input is 28). Others quit at 17 volts or higher. This is important, because in an emergency your lights can continue to operate.

PWI has a decades-long history of supplying OEM lights for Gulfstream, Falcon, Citation, King Air, Sabreliner and Lear Jets. PWI remains the OEM for cabin lighting with Textron/Beechcraft. If you have a King Air, you already have PWI lights.

 

What are the benefits of upgrading to PWI LEDs?

  • PWI LEDs offer 100,000-hour service life
  • Plug and play installation – right connectors
  • Lower current draw allows lights to remain on when only battery power is available – loading and unloading passengers and/or cargo
  • Passed rigorous FAA certification testing
  • Offer two color temperature options
  • Over time, LEDs are less expensive than incandescent bulbs 
  • PWI LED’s are competitively priced

 

What are Lumens?

Lumen is used to measure the level of light brightness. The higher the level of lumens produced by a lamp, the brighter the light.

Depending on the desired lighting situation, it may require a higher lumen output to create the desired lighting effect. Special Missions aircraft such as air-med transport are often fitted with brighter LEDs for patient safety reasons.

 

What is color temperature?

Color temperature is the color of light produced. White light is measured in Kelvin (K) and falls in a range between 1800K and 7000K. Where the light falls in the spectrum, determines if the white light produces more of a “warm white” or “cool white”. White light around 3000K produces a warmer tone, while white light around 6500K produces a cooler blue-ish tint. Color temperature choices allow aircraft owners to design the cabin experience they desire.

Can I purchase your aviation lights prior to FAA certification?

Yes, some of our pre-certified aviation products are available for purchase and installed using an FAA Form 337 – Field Approval. Typically an FAA inspection is required to verify “fit, form and function.”

Can I still get fluorescent lights or repairs?

Yes you can. 

We build brand new fluorescent lights every day. We have 1800+ part numbers and create lights and power supplies for those jets we supplied as an OEM vendor:
Falcon
Gulfstream
Citation
Beechcraft
King Air
Lear
Sabreliner

If you choose to request a power supply repair, it’s a simple three step process.

Coil Windings

Can PWI build my specific coil winding?

PWI started building windings in 1963. It’s what built our business. We have experience building a broad range of winding products, usually used as a subassembly in a finished product. Call us at 316-942-2811 to discuss your winding project.

Project examples include:

  • High Voltage Output Transformers
  • Switch Mode Transformers
  • Current Sense Transformers
  • EMI/RFI Filters
  • Torodial Power Inductors
  • Common Mode Chokes
  • Magnetometer Coils
  • Air Coils
  • Solenoid Coils
  • Antenna Load Coils

Magnetometers

 

Can PWI build my custom magnetometer – even one of those hard-to-find flux gate magnetometers?

Yes, we build magnetometers using various wire gauges, core materials and winding techniques to customize magnetometers to suit your specific needs. Call us to explore your magnetometer options.

There are only a very few companies in the world that can create flux gate magnetometers, and PWI is one of them. The engineering possibilities offered by these mags are unique and create options in product design that cannot be found using other technologies.

Warranties and Repairs Questions

 

What is the warranty on my product?

All product warranties begin at the invoice date.
LED aviation lights – 3 years
Fluorescent lights, magnetometers, coils, windings – 1 year
Power supply repair – 6 months from the repair invoice
Power supply overhaul – 12 months from the repair invoice

Contract Engineering and Manufacturing

 

What does Contract Engineering mean to me?

Contract engineering is a comprehensive range of scalable, value-added electronic engineering services. PWI’s extensive contract engineering services meet the needs of a variety of customers. PWI will tailor our work to complete your project. 

Often this work is outlined in a Statement of Work (SOW) proposal that clearly spells out the details of any work to be performed, the desired features and the costs of the project.

PWI can provide as much engineering assistance to your product idea and requirements, as needed. Our services include anything from concept design development and prototyping, to in-house electronic testing and more. PWI can also help build the completed product designs by our contract manufacturing staff.

 

What is contract manufacturing?

Contract manufacturing is an agreement between PWI and our customer where we produce components or products for our customers. We have customers that have completely engineered and tested prototypes, but need assistance in building quantity production. If you need help in building your products or components, PWI has the capabilities.

PWI has completed custom projects for a variety of industries outside of aviation. If we can assist you with any specific projects, just call or email. We’d be happy to discuss your project needs.

Purchasing Questions
 
How can I purchase PWI products?
