PlexBright LD-1 Single Channel LED Driver

The PlexBright® LD-1 Single Channel LED Driver is one of two Plexon products to drive and control optogenetic stimulation. It is an economical, stand-alone alternative for use with PlexBright LED Modules.

The PlexBright LD-1 Single Channel LED Driver (LD-1 LED Driver) is a powerful, compact, light-weight and economical alternative used to provide independent control output of up to 1200mA to one or two PlexBright LED Modules – a great choice for those wanting to deliver constant light output, or are able to generate their own TTL/analog control signals.

The LD-1 LED Driver features:

  • Precision dial and display: Can be used to modulate a constant output current to control PlexBright LED Module output at a set intensity. This output may also be manually pulsed.
  • TTL input: Accepts a TTL input for generating precisely timed pulse patterns at the intensity set with the dial-and-display with sub-millisecond response times.
  • Analog input: Accepts an analog input that can be used to deliver arbitrary output patterns such as ramps or spikes.

The LD-1 LED Driver can control one LED Module or two LED Modules simultaneously with each module receiving the same control signal. This dual-mode configuration is particularly applicable to bilateral stimulation experiments.

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 LD-1 Single Channel LED Driver (economical kit), or our more sophisticated device, the PlexBright 4 Channel Optogenetic Controller with Radiant™ Software (fully functional kit). 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, or on the Documentation page under the PlexBright header.

In addition to the LD-1 LED Driver, the PlexBright Optogenetic Stimulation System also offers the more sophisticated PlexBright 4 Channel Optogenetic Controller running PlexBright Radiant Software; a full range of super intensity PlexBright LED Modules; several commutator options; high performance PlexBright Optical Patch Cables with a choice of stimulation tips; 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 CineLyzer® Behavioral Research Systems.

Your Plexon Sales Engineer is available to provide additional information and to assist you in determining what product configuration might be the best choice for supporting your research.

Device platform Current As a stand-alone system, the LD-1 LED Driver provides a constant current output at the selected amplitude.
Current output up to 1200mA
Manual pulse Yes
Analog input 0 to 5V The LD-1 LED Driver accepts an optional analog input to modulate arbitrary current output to the PlexBright LED Modules directly or through our PlexBright Commutators.
TTL input Yes The LD-1 LED Driver accepts an optional TTL input to modulate pulsed output to the PlexBright LED Modules directly or through our PlexBright Commutators.
Compatibility with LED modules All PlexBright LED Modules
Compatibility with commutators
– PlexBright Dual LED Commutator,
– PlexBright Dual LED + 16 Channel Commutator for simultaneous use with analog headstages, and
NEW Carousel™ Commutator for simultaneous use with digital headstages
 If the identical parameters are desired for both modules on the commutator – such as for bilateral stimulation – a PlexBright Series-Y BNC Cable will also be required
Number of modules controlled simultaneously 1 or 2 The LD-1 LED Driver can operate two PlexBright LED Modules in which identical parameters are desired for both stimulation sites. A PlexBright Series-Y BNC cable is required to accomplish this.
Dimensions (H x L x W) 2.6 x 5.5 x 10.5cm
Weight 250g
Accessories PlexBright Series-Y BNC Cable The PlexBright Series-Y BNC Cable enables the simultaneous operation of two PlexBright LED Modules from a single channel in which identical parameters are desired for both modules.
