I am always looking for a curved LED fixture that throws light far instead of creating a blob of light, and QTL has been the best I've found.

Rachel Levy, Founder of RL Designs

QTL’s support goes beyond the quality of their products. We need manufacturers who aren’t just manufacturers, but our design partners.

Ken Ventry, Principal at Reveal Design Group

The consistency of color, the number of options we have within a single manufacturer – whether it’s the variation of wattages, color temperatures, or all the extrusions we could need. I knew I was going to get strong, quality consistent dimming.

Stephanie Daigle, Senior Lighting Designer at Focus Lighting

QTL products dim nice and low because of their quality drivers.

Garret Neal, Principal at NEAL

The 1.5-watt LED strip is hard to get anywhere else, and the ability to get to 1% dimming allows seamless transition from day to night. QTL is my preferred brand for hospitality lighting.

Edwin Allen, Lead Lighting Designer at Focus Lighting

The dimming from QTL is a lot better than other LED manufacturer's products I've come across; It works seamlessly and with better range.

Rachel Levy, Founder of RL Designs

If we need something with a very specific optic that needs to perform a certain way, QTL is always in the running. I also appreciate QTL’s approachability and willingness to collaborate.

Erin Flaum, Partner and Design Director of Architectural Lighting Design at Zutalé Design,

People want to know where the light source is from, and like that it’s from QTL. They know the company and use QTL products on other jobs.

Adam Shay, Product Development & Quality Control Manager at Structura

It was important to find a manufacturer that has a wide array of optics and flexibility in mounting. The fact that I can specify and can modify as needed is a major reason we go with QTL

Shelby Klooster, Lighting Designer at RDG Planning & Design

We had worked with QTL before and were confident it’s an established company and wasn’t a risky choice for us. It comes down to QTL having the best performance, options and LED extrusions.

Kristen Peck, Principal + Co-Founder, PritchardPeck Lighting

QTL is one of my go-to LED tape light manufacturers because I know they are of high quality, withstand time, and ultimately look a lot better and save money in the long run.

Rachel Levy, Founder of RL Designs

I can use a brighter QTL tape in one area and pair it with a lower wattage tape elsewhere and be confident in knowing they're going to perform similarly, which is great.

Stephanie Daigle, Senior Lighting Designer at Focus Lighting

The ranges in color temperatures, lens options, and tight pitches the products deliver are exceptional. To me, diode-free results equate to high quality products.

Edwin Allen, Lead Lighting Designer at Focus Lighting
