Philco 15DX light replacement
#9

Yes, that bulb you recommended probably would not be an issue. I took a close look at the photo and the smaller size screw base would have no room for a switching supply. Most likely it just uses a series capacitor for current limiting, generating no RFI.

The miniature #44 and 47 LED replacements are also no problem as they just use series resistors to limit current. I've taken a couple apart and its amazing how much they pack into that tiny base. There is a bridge rectifier, filter capacitor and two dropping resistors on a tiny circuit board just under the actual LED.

Its too bad they don't seem to make the #40 style miniature screw base lamps in LED. I have had to take wedge base LEDs and disassemble to fit them to old screw bases from burned out bulbs.
