LED Grow Lights with Independent Control of LEDs

BoulderLamp, Inc. (BLI), makes the most efficient CMH and LED grow lights. Our newest innovation is the PerfectPar™ series LED grow lights giving you the independent control of white-red or blue-red ratio  for you to have broader choices over plant lighting spectrum. We use OSRAM latest generation LEDs to make the most efficient horticulture grow lights. PerfectPar™ series LED grow lights are rugged and built to last. They can be used for indoor, vertical farm, and greenhouse cultivations. 

Boulderlamp’s PerfectPar™ DuoLight 4000 with sequentially moving light beam technology provides an unprecedented level of control over photosynthetic lighting for controlled environment agriculture. Rather than dimming the entire fixture, as is the case for all other commercially available dimmable grow lights, our DuoLight 4000 dims each light bar separately, precisely, and automatically. This improves light uniformity over the growing area and gives you a high precision, fine-scale control over the amount of light your crops are getting, as well as the amount of electricity you are using.

Why BLI Grow Lights?

Light Spectrum

Our Color Augmenting LED grow light utilizes top bin 100% OSRAM white and red horticulture LEDs to create optimized sunlike full spectrum for faster growth and bigger harvests.

Design Simplicity

Our lights are easy to install:
modular and daisy chain connections can also be dimmed using off-the-shelf 0-10V dimmer.
LED driver architecture allows on demand wireless communications.


Lower cost of ownership due to our innovative design structures. Single bar quick attach modular system also allows “add as you grow” low cost expansion architecture.

Built in the USA

We are proud to build our products in the USA using components sourced in the US and around the globe. We source only the highest quality parts and components to ensure top performance.
