NIGHTSEA Pulse Option

Lamp Base Light Control Options

The SFA lamp base is available in three versions: Standard, DIM, and PULSE. Standard lamp bases have a simple OFF/ON operation. DIM lamp bases feature an OFF/ON/DIM switch to change the intensity of the light. PULSE lamp bases incorporate a BNC connector that accepts a voltage signal to control the excitation source ON/OFF.

Only one control option is available per base. This DIM and PULSE options can be purchased as part of a new system, as a retrofit to an existing base, or in a stand-alone lamp base purchased a la carte.


The PULSE option adds a BNC connector on the rear of the base that accepts a user-supplied voltage input to turn the light on and off. Some possible applications

  • External control (computer, function generator, etc.) for precise illumination timing for photoactivation, behavioral experiments
  • PWM input for light dimming
  • Footswitch for hands-free operation - contact EMS for details


  • Voltage input - 2.8 - 6.0 VDC for ON, <0.6VDC OFF
  • Maximum operation frequency - 10kHz
