PlexBright LED Modules

At the heart of the PlexBright® Optogenetic Stimulation System are the cost-effective and powerful PlexBright LED Modules for standard use (Table-top LED Modules), or for use with our PlexBright Commutators for freely behaving animals (Compact or New Head-Mounted LED Modules). A full spectrum of wavelengths enables you to get the most out of your research whether you are performing acute or chronic in vivo experiments or in vitro preparations.


**NEW HELIOS Wireless Optogenetics System: Plexon's newest innovation in optogenetic technology which provides a wireless, lightweight, and reusable solution for high power pulsed optogenetic stimulation in freely moving small animals.**


Plexon’s second generation, super-intensity PlexBright LED Modules provide outstanding light stability and pulse characteristics – all within a very small footprint. Our ever-expanding series of powerful, fiber-coupled PlexBright LED Modules effectively elicit responses from several opsins targeted in neuroresearch, including channelrhodopsins (ChRs), archaerhodopsins (Arch) and halorhodopsins (NpHR).

PlexBright LED Modules come in a wide range of wavelengths and are capable of emitting continuous, stable, and quick-responding light through the tip of a 200μm core, custom developed optical fiber.  PlexBright Table-top and Compact LED Modules are available in the following seventeen wavelengths: Royal (450nm), Blue (465nm), Green (525nm), Lime (550nm), Yellow (590nm), Orange (620nm), Red (630nm) Crimson (660nm), Infrared 1 (850nm), Infrared 2 (940nm), Near-Infrared 1 (740nm), Near-Infrared 2 (760nm), Near-Infrared 3 (780nm), Near-Infrared 4 (810nm), Ultraviolet 1 (365nm), Ultraviolet 2 (385nm), and Ultraviolet 3 (405nm). The Head-Mounted LED modules are available in Blue (465nm), Green (525nm), Lime (550nm), and Orange (620nm)

PlexBright Table-top LED Modules for standard use are small devices most often chosen to support: 1) in vitro work; 2) in vivo experiments with anesthetized animals, or; 3) in vivo experiments with behaving animals when a commutator is not required to prevent tangling of cables.   


PlexBright Compact LED Modules provide the same performance as the PlexBright Table-top LED Modules, only in an ultra light-weight and miniaturized package designed to be mounted to either of our PlexBright Commutators that deliver power to the LEDs as they spin freely along with a behaving animal. These modules have recently been enhanced to feature a magnetic connection to the commutator. The new style of magnetic attachment enables faster module interchangeability. These Compact LED Modules are compatible with the PlexBright Dual LED Commutator, PlexBright Dual LED + 16 Channel Commutator for simultaneous neural recording with analog headstages, or the NEW Carousel™ Commutator for simultaneous neural recording with digital headstages. 



NEW Head-Mounted LED Modules are miniaturized for placement directly on an animal’s head (available in blue, green, lime, and orange).



NEW Magnetic Head-Mounted LED Modules include a magnetic optical rotary connector that can be used with the NEW magnetic fiber stubs to relieve the torque on the implant from rotational movements such as spinning and twirling  (available in blue, green, lime, and orange). 



For maximum power output to the stimulation site, high performance PlexBright Optical Patch Cables have been designed to easily connect to the modules. It is important to note that our PlexBright Optical Patch Cables are LED module style-specific.

PlexBright Starter Kits offer the initial products to get started and a 10% discount when purchased as a kit. Kits are available in four experimental designs and with either driver (the economical kit with the LD-1 Single Channel LED Driver or the fully functional kit with the PlexBright 4 Channel Optogenetic Controller with Radiant Software). Starter Kit details are available on the PlexBright Quote Request Forms.

PlexBright Quote Request Forms (also specific to the experimental set-up) include the Starter Kit itemization and individual parts for selection. The forms are available on the Resources tab, as well as on the Documentation page under the PlexBright header.

In addition to super intensity PlexBright LED Modules, Optical Patch Cables and Commutators, the PlexBright Optogenetic Stimulation System also offers the PlexBright LD-1 Single Channel LED Driver; the more sophisticated PlexBright 4 Channel Optogenetic Controller running Radiant Software; specially designed PlexBright Fiber Stub Implants; the PlexBright Light Measurement Kit; and the PlexBright Optical Fiber Cleaning Kit to safely maintain and extend the life of the fiber tips. If your experiments include freely behaving animals, you may also be interested in learning more about the CinePlex® and CineLAB® Behavioral Research Systems.
