How can I set the font size for popup menu

I tried all possible options, but I cannot seem to figure out how to change the font size of the pop up menu inside a control object for Manipulate.

{{Application, "Energy Storage"}, {"Energy Storage", 
  "Shock Absorption", "Pulsation Dampener"}, ControlType -> PopupMenu,
  Background -> LightGray, FieldSize -> 17}

I would appreciate some help. Thanks.

You have to use val → lbl syntax and style labels. Like this:

Manipulate[
 Application,
 {{Application, "Energy Storage"},
   Thread[ # -> Thread @ Style[#, Bold, Red, 18] ] & @ {"Energy Storage",  "Shock Absorption", "Pulsation Dampener"}, 
   ControlType -> PopupMenu}
 ]

This was tremendous! Thank you so much.

Another way:

Manipulate[Application,
 	{
  	  {Application, "Energy Storage"},
  	  {"Energy Storage", "Shock Absorption", "Pulsation Dampener"},
  	  MenuStyle -> {Bold, Red, fontsize}, ControlType -> PopupMenu
  	},
 	{{fontsize, 18, "Size"}, {12, 18, 24, 48}}
 ]
