The PHILCO Phorum

This is just a little drawing I whipped up to help advertise the serious power lurking inside the Zenith 8-S-563. I drew this completely freehanded in about half an hour. The lighting is two 40 watt mercury vapor lamps.

Hold H**l, Mark your calenders!

A Mercury vapor lamp is meant to burn much brighter than a standard bulb. Especially high pressure lamps.

Are these new bulbs? These bulbs need a burn in period when first lit. At least an hour and they can be brighter in the beginning. They can burn 10-100 times brighter.
Another thing can be the Ballast having an issue.
This is not set up as a Dim bulb tester right? If that is the case then there may be a short in the DUT but I am pretty sure in a darker room with light walls it is just the bulb.

Now watch me be wrong and get blown out of the water

This fixture has been working fine for a year and a half.

The two light globes look like....you know what.
