Unknown Philips? « on: May 19, 2022, 12:30:36 AM » Author: N3210
Here is a (Dead) Philips that is now in my collection. It would not turn on, and I believe I hear loose filament shaking. Closely resembles this:  Google search returns nothing. This bulb fits in E26/E27 base

Back in the 1980s and 1990s, these incandescent bulbs were marketed for having a 33% longer life compared to other incandescent bulbs manufactured at the time. Here are several videos that advertise them: https://youtu.be/sfsK7bVvIu8 https://youtu.be/sVLRgWkbh_Y https://youtu.be/yCnp1nv3UkY https://youtu.be/1Sa2XARAMqk

Apparently, these last "33% longer than regular bulbs" but this one has a dead filament and the "golf ball" that this bulb was found by, is still alive today!

These are known as the “square bulbs” by Philips. This design was carried over from Westinghouse after Philips bought out their lighting division in 1983. The “33% longer” was really a marketing gimmick in my book, as Philips (post-Norelco) was new to consumers at the time and needed something to stand out from the rest. They’re interesting bulbs and worth holding onto even if burnt out.
