Sylvania CapsyLite 72w Halogen

Sylvania CapsyLite 72w Halogen

Click to view full size image

An early version of the popular 72-watt 100w incandescent halogen replacement, from only about 25-30 years before they became mandatory. Unlike the modern versions, this is constructed of heavy bottle glass and has a 3500 hour life, yet achieves similar lumen ratings (Modified spectrum soft white 72 watt halogens are about 1270 lumens, clear ones are about 1490).

I haven't yet lit this one but I know these have a characteristic diode flicker. As I recall, these use an 85v capsule, hence the diode, effectively dropping the observed voltage across the filament thereof. They had a characteristic diode flicker and I believe one of the reasons this design failed and these eventually underwent product deletion by Sylvania was because they caused problems on dimmer switches. I'm curious how this will behave on modified sine wave inverter electricity and will try and report back. This thing physically weighs about a pound!

I believe these were an '80s and early '90s thing, can someone confirm that?

Ironically I used to have a 42w version of this but gave it to fellow member IceFogLights, who in turn a couple years later gave me this one. Full-circle.

I think that the problem of flickering from the diode, is mainly when operated at 50hz. In 60hz the flickering is invisible to the naked eyes.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230V, 50hz country.

I had one, but the capsule exploded on me.

I'll save any vintage light... dead or alive! Smiley

I can still see that "flicker" on those diode-powered halogens here in the States. Not unlike that of a rectifying fluorescent.

Mine was also 60, I believe.
