Collins  S-Line Solid-State LED   illumination     Click on  picture for an expanded view Is it time to update your Collins S-line?  I offer here the chance to replace the PTO and Meter incandescent lamps with modern plug-in-play solid-state LED lamp replacements.    I have been offering such replacements for the Drake 4-line users and they have been received  so well that I pursued designing similar replacement lamps for my own Collins S-Line.   In the picture above the 75S-3 receiver on the left is using the original incandescent #47 lamps.  The 75S-3C on the right uses my new white LED lamp replacements.  Gone is the yellow glow and heat of the incandescents! The life of an LED is longer than incandescent bulbs.  You will save on current draw!  The two LED lamps only require a total of 40mA whereas the original #47 lamps have a total of 300mA current draw.  That's over one quarter amps less current draw from the power supply and negligible heat dissipation from the LED's.  PTO  Comparison Below is a picture of the before amd after pictures of the Solid-State LED lamp replacement.  Click on either picture for an expanded view. Original Incandescent New LED Lamp     Collins S-Line Kit One Set Supports One Transceiver, Transmitter or Receiver. A Collins 75S/32S Pair will require Two (2) Sets. One  Frosted LED Bayonet Lamp One Diffused Lens LED Bayonet Lamp Full Installation Instruction Sheet  Analog Display (PTO) Lamp (Above Left)   Meter Lamp (Above Right) Built With A Purpose These are not mass produced lamps.  Each lamp is  hand assembled  in my shop.  The bayonet bases are solid brass.  The meter lamp uses a frosted lens LED.  The analog display (PTO) lamp has a special manufactured diffusion lens which surrounds the LED.  This dispersion lens is milled from a solid semi-transparent polymer.  It is not a hollow plastic covering!  By using a solid lens material the emitted light is dispersed all around the lamp, even below the base line. Simple to Install Installation is straight forward and every attempt was made for ease of installation.  This is a direct lamp replacement  and can be performed at the same speed as changing the original incandescent bulbs.
