We are Spectrum King

Spectrum King has been an innovation leader since day 1.

The company began life as a small startup in a Los Angeles garage, working to invent something that would eventually change the horticultural world forever. We had been growers for years, working under hot, wasteful, environmentally irresponsible HPS lights. We were sick of the energy bills, the heat, and the ugly yellow lighting that made it hard to read plant health. We knew that the only way to change this was to invent a new future, and that LED lighting held the key.


After many months of research, Spectrum King had its “eureka” moment. One of our experimental full spectrum LED lights produced bigger, denser crops than anyone had ever imagined possible with the technology. We patented our invention (patent no. 10238043), and launched an entire industry. We’ve been engineering in pursuit of perfection ever since, never settling for a “good enough” answer. It’s why our specs are second to none.

Come explore our world, we think you’ll like what you see.

UNCOMPROMISING ENGINEERING

We’re an engineering powerhouse that happens to make lights. Whether it’s a rocket ship or a grow light, success starts with premium materials. Good thermal management, spectrum consistency, efficiency, and output strength all depend on starting with the right components. Spectrum King has always and will always use:

  • Top bin diodes from Tier 1 manufacturers

    We go a step further than most, working only with top diode manufacturers on custom designs to maximize performance, where our competitors typically just buy chips off the shelf.

  • Space age frame materials

    Our frames are designed to efficiently pull as much heat away from the diodes as possible, and are custom designed to minimize microclimates.

  • Automotive grade plastics

    Our plastics are the same type you would find in an automotive engine block.

  • Premium mechanical materials

    Our wiring, connectors, seals, and other components are always top quality for their specified purpose.

A HISTORY OF INNOVATION LEADERSHIP

Spectrum King has always been the undisputed leader in LED lighting innovation. We haven’t just blazed one trail – we’ve built an entire industry.

  • The World’s First Full Spectrum LED Grow Light

    The World’s First Full Spectrum LED Grow Light

    Spectrum King created the world’s first ever full spectrum LED grow light, and was granted patent no. 10238043 for its invention.

  • THE WORLD’S FIRST POINT SOURCE LED GROW LIGHT

    THE WORLD’S FIRST POINT SOURCE LED GROW LIGHT

    Spectrum King pioneered the point source, 1:1 HPS replacement design with the SK600.

  • The World's First Dedicated Vegetative LED Grow Light

    The World's First Dedicated Vegetative LED Grow Light

    Spectrum King was the first LED lighting company to produce a true, dedicated vegetative spectrum. We still deliver the bushiest, best veg phase of anyone.

  • FIELD TESTED

    We know because we grow. Good results on paper don’t always mean good results for plants. Everything we make passes rigorous performance evaluations at 818 Brands, a premiere 120,000 square foot commercial grow in California, growing cycle after cycle of premium quality plants.

  • WHITE GLOVE, CONSULTATIVE SERVICE

    Everyone in our organization has years of experience consulting for and operating commercial grows. We know that it takes time to dial in a facility, and the last thing growers need are suppliers who disappear when the check clears. We’re in it for the long haul with our customers, whether it’s helping to spec a facility that’s in the design process, or working on solutions to successfully transition over from HPS to LED lighting. Most importantly, we guarantee a response within one business day if you ever need our assistance for any reason. We will always be here for our grow partners.

  • WE NEVER RUN FROM A COMPETITION

    We know, based on data and on experience, that there is not a single company offering any light of any type that can compete with what Spectrum King offers. Test us out against anyone, we’re not afraid of a little friendly competition. Just email us at sales@spectrumkingled.com if you want to take a test drive.

  • BUILT TO LAST

    All of our lights are built to thrive in the harsh realities of the daily grow environment.



    • IP65 rated: waterproof and dust tight to handle any moisture and particles they will encounter in regular usage.


    • Q90 rated: diodes will not degrade more than 10% beyond their initial output for over 60,000 hours.


    • Dual surge immunity: both the driver and the circuit board on each light are independently surge protected with the highest quality surge protector in the industry. Each will independently respond to a power surge in mere nanoseconds, shrugging off power events that would fry most lights.


    • 5 year warranty:coverage on our fixtures for five years.

  • Certifications

    All of our lights are CE and ETL certified safe for use in both the United States and Europe. They are also DLC Horticulture Listed, meaning they are eligible for rebates in jurisdictions throughout the United States.
