Features Include:

  • Lightweight modules can be used with mice and rats without impeding behavior
  • Infrared communication, controlled by the PlexBright 4 Channel Controller or TTL device, eliminates the need for patch cables
  • Charge and re-use the LED Module repeatedly in multiple subjects

                                                     

Calculate Battery Life:

Duty cycle is the percentage of time the LED light output is on relative to the total time the receiver is turned on

Example:

How long will the battery last on a Blue HELIOS LED module if you deliver 15mW pulses with a 5% duty cycle?
