Sylvania 130v 500w Mogul Here's a unknown incandescent lamp that came with my Powerlite gumball, surprisingly it still works too. It's shown lit up in my R47 which I bypassed the ballast briefly for testing. I don't know who made this or the exact wattage/date but when I tested it, I found that it drew around 3.47A and 416 watts. Some design features I've are that, it has a heat deflector disk, the glass insulator on the base is black and taped. The etch was mostly faded, all I could make out was a W, there's a pic of it here: [IMG]http://i560.photobucket.com/albums/ss50/joseph_125ON/Gallery%20of%20Lights/c3436aa3.jpg[/IMG] EDIT: Thanks to Dave for the info.

Possiblity could be originally 500 Watts bulb now that most of the filament evaporated to the wall of the envelope Confused

Hmm, I thought it was a streetlighting bulb which I was told had odd wattages since they're rated by lumens instead.

Joe, that is a 500w 130v lamp made by Sylvania. Its not a street lighting lamp, these come with a 3 or 5 support filament.

Ah thanks anyways Dave, I guess I'll stick with the 300w clear Sylvania for now until I manage to find a real streetlighting lamp.
